A bathroom exhaust fan is a mechanical ventilation device which, when ducted to the exterior of the house, draws out stale, impure and very humid air thereby improving the quality of indoor air. A properly installed bathroom exhaust fan will rid the bathroom air of excess moisture, humidity, odors and other pollutants, Northfield, IL ac hvac rooftop units residentail and commercail heating and air conditioning free estimates experts, service repair and installation AirEase
Central heating or cooling equipment (furnace, air conditioner, or heat pump) contains a fan that forces heated or cooled air into supply ducts leading to the rooms. The fan gets its air supply through return ducts, which in the best systems are installed in every room of the house.

Your combi boiler diverter valve is a valve that opens and closes to provide heat to the radiators or to heat your water. The diverter valve will always give priority to your hot water, so if you turn your heating on, and then a hot tap, it will heat the water to the tap first, Edgewater, Chicago, IL ac hvac rooftop units residentail and commercail heating and air conditioning free estimates maintenance, service repair and installation Ameristar
Boilers are pressure vessels designed to heat water or produce steam, which can then be used to provide space heating and/or service water heating to a building. In most commercial building heatingapplications, the heating source in the boiler is a natural gas fired burner. Oil fired burners and electric resistance heaters can be used as well. Steam is preferred over hot water in some applications,

Boilers have several strengths that have made them a common feature of buildings. They have a long life, can achieve efficiencies up to 95% or greater, provide an effective method of heating a building, andin the case of steam systems, require little or no pumping energy. However, fuel costs can be considerable, regular maintenance is required, and if maintenance is delayed, repair can be costly. Both gas and oil fired boilers use controlled combustion of the fuel to heat water. The key boiler components involved in this process are the burner, combustion chamber, heat exchanger, and controls, Lake View, Chicago, IL ac hvac rooftop units residentail and commercail heating and air conditioning free estimates technicians, service repair and installation Armstrong
The burner mixes the fuel and oxygen together and, with the assistance of an ignition device, provides a platform for combustion. This combustion takes place in the combustion chamber, and the heat that it
generates is transferred to the water through the heat exchanger. Controls regulate the ignition, burner firing rate, fuel supply, air supply, exhaust draft, water temperature, steam pressure, and boiler
pressure. Lincoln Park, Chicago, IL ac hvac rooftop units residentail and commercail heating and air conditioning free estimates serviceman, service repair and installation Bryant
Hot water produced by a boiler is pumped through pipes and delivered to equipment throughout the building, which can include hot water coils in air handling units, service hot water heating equipment,
and terminal units. Steam boilers produce steam that flows through pipes from areas of high pressure to areas of low pressure, unaided by an external energy source such as a pump. Steam utilized for
heating can be directly utilized by steam using equipment or can provide heat through a heat exchanger that supplies hot water to the equipment. Gold Coast, Chicago, IL ac hvac rooftop units residentail and
commercail heating and air conditioning free estimates servicing, service repair and installation carrier
The pressure difference between the boiler combustion chamber and the flue (also called the exhaust stack) produces a draft which carries the combustion products through the boiler and up the flue.
Natural draft boilers rely on the natural buoyancy of hot gasses to exhaust combustion products up the boiler flue and draw fresh air into the combustion chamber. Mechanical draft boilers include: Forced
Draft, where air is forced into the combustion chamber by a fan or blower to maintain a positive pressure; and Induced Draft, where air is drawn through the combustion chamber by a fan or blower to
maintain a negative pressure. Old Town, Chicago, IL ac hvac rooftop units residentail and commercail heating and air conditioning free estimates trouble shooting service repair and installation Comfortmaker
Boilers are classified as either low pressure or high pressure and are constructed to meet ASME Boiler and Pressure Vessel Code requirements. Low-pressure boilers are limited to a maximum working
pressure of 15 psig (pound-force per square inch gauge) for steam and 160 psig for hot water (2). Most boilers used in HVAC applications are low-pressure boilers. High-pressure boilers are constructed to
operate above the limits set for low-pressure boilers, and are typically used for power generation. Operating water temperatures for hot water boilers are limited to 250o
F (2). Bucktown, Chicago, IL ac hvac rooftop units residentail and commercail heating and air conditioning free estimates repairing, service repair and installation Concord
If your home doesn't have a hot-water tank, you probably have a hot-water or steam home-heating system that also heats water for your taps. To accomplish the job, your boiler has a tankless water heater. In this system, a coil of pipe is connected at one end to the cold water supply, and at the other to your hot-water delivery piping. As the boiler heats the water that warms your home, that water heats the coil, creating hot water at your taps. Logan Square, Chicago, IL ac hvac rooftop units residentail and commercail heating and air conditioning free estimates fixing, service repair and installation Daikin
Because tankless heaters only heat water as it's used, there's no cost for maintaining heat in a large volume of water during periods of low usage. However, they do have a few drawbacks. First, the hot water generated is far hotter than necessary, so a cold-water mixing valve should be installed to reduce the chance of scalding. Second, the boiler must fire to generate hot water—which is efficient during the winter months, but decidedly more wasteful when the weather is warm. Like tank-type heaters, tankless heaters are designed to achieve a specific heating rate. Once the rate is exceeded by demand, the temperature of the water drops. In some cases, storage tanks are connected to the heating coil to increase hot-water availability. Avondale, Chicago, IL ac hvac rooftop units residentail and commercail heating and air conditioning free estimates cleaning service repair and installation day and night
In addition to boiler-mounted tankless heaters, stand-alone units are available. Gas-fired instantaneous water heaters utilize a coil and heat exchanger to heat water as it's required. Like boiler-mounted units, instantaneous water heaters don't use energy to maintain the heat in a volume of water, but only fire as hot water is required. A downside is that stand-alone units typically have a lower flow rate than boiler-mounted systems and may fall short during periods of high demand. Because water heaters both heat and store water, the rate at which the water is heated and the capacity of the tank affect the supply of hot water at your fixtures. The speed at which a unit heats water is called its recovery rate. This figure indicates the amount of water in gallons that can be heated to 100 degreesF in 1 hour. Once you draw water faster than it's heated, the temperature drops. Forest Glen, Chicago, IL ac hvac rooftop units residentail and commercail heating and air conditioning free estimates serviceman, service repair and installation Trane
However, because the tank stores hot water, its capacity also affects the ongoing availability at the tap. Choosing a water heater that has an appropriate capacity and recovery rate depends on how much water your home demands and how your unit heats the water. Typically, heaters with low recovery rates have a high tank capacity. Although it takes longer to heat the water, there's more of it for intermittent use. Electric heaters fall into this category. On the other hand, a fuel-fired heater with a high recovery rate needn't have a large tank, because it can heat the water faster. In general, electric models have the lowest recovery rate, and oil-fired units have the highest. Irving Park, Chicago, IL ac hvac rooftop units residentail and commercail heating and air conditioning free estimates checking, service repair and installation Fraser Johnston
Instead of electrical-resistance elements, gas-fired heaters have a burner that's fed gas through a control valve and a thermostat switch. In an oil-fired heater, the burner is similar to that found on an oil-fired furnace. In either case, the burner is usually situated to throw a flame under the tank. The exhaust gases are vented either through a hollow core at the center of the tank or around the tank sides. Because fuel-fired heaters heat the tank, which in turn heats the water, there will be more wear and tear on the tank than with electric heat. A fuel-fired heater, therefore, may have a shorter life expectancy than an electric heater. Albany Park, Chicago, IL ac hvac rooftop units residentail and commercail heating and air conditioning free estimates replacements service repair and installation Frigidaire
Power is delivered to each element through a thermostat—a switch that senses the water temperature. When the temperature drops, the switch closes to allow current flow, and it opens when the temperature reaches its preset limit. Thermostats have a dial for setting the maximum water temperature—generally between 130 degrees and 140 degreesF, or as low as about 120 degreesF for increased energy savings and scald protection. Humboldt Park, Chicago, IL ac hvac rooftop units residentail and commercail heating and air conditioning free estimates installations, service repair and installation Gibson
When a hot-water tap is opened, cold water enters the tank through the dip tube and the drop in temperature triggers the thermostat and element at the bottom. As the water at the top of the tank is replaced by cool water, the temperature at the top thermostat drops and its element kicks in. When the tap is turned off, the heating elements continue to carry current until the thermostats are satisfied.The typical electric unit is wired to a 220-volt circuit. To heat the water, the current passes through electrical-resistance heating elements—usually two, one at the middle of the tank and one at the bottom.

The standard water heater comes in two flavors: electric and fuel-fired. In the latter, the fuel most commonly used is gas, either natural or propane, but oil-fired heaters are popular in many areas. Fuel-fired units have a vent pipe at the top to carry away exhaust gases. Electric models, on the other hand, simply have a power cable that connects the heater to your electric service panel.

The job of the tank-type heater is not only to heat the water, but to store it until it's ready to use. Therefore, in addition to the tank's heating system, every tank is equipped with insulation to help keep the water warm between heating cycles.Wicker Park, Chicago, IL ac hvac rooftop units residentail and commercail heating and air conditioning free estimates furnace service repair and installation Lennox
On top of every tank you'll find the water supply and delivery pipes. The supply pipe routes cold water to the bottom of the tank through the dip tube. The hot-water delivery pipe takes water from the top. For safety, all water heaters are equipped with a T&P valve (temperature-and-pressure relief valve). This valve opens if either the temperature or pressure of the water exceeds a safe limit. The valve is connected to a pipe that runs down the outside of the tank, ending about 6 in. from the floor. It's a good idea to keep a bucket under the end of the pipe to catch water if the valve opens. The T&P valve should not be connected to a drain. If the valve did open, a sign that a problem exists, you might never know that it had opened.

Most tanks are made of steel, which is glass-lined on the inside to help prevent corrosion. In fact, corrosion is the primary reason that tanks fail. Once rust produces a hole, there are temporary fixes, but the tank should be replaced. All tanks also have an anode rod to control corrosion. The magnesium anode rod protects the tank by corroding in place of the steel. Because the rod is designed to corrode, it will eventually wear away. After this happens, corrosion of the steel accelerates. It's a good idea to check the anode rod once a year, and replace it if necessary. At the bottom of every tank is a drain cock to empty the heater, and a valve on the supply pipe allows you to shut down the hot-water plumbing without affecting the cold-water supply to the house.

Most homes have a tank-type water heater. If you find a large, cylindrical tank standing on end with pipes attached to it, you have a tank-type system. If you don't find a tank, but you have a hot-water heating system that heats your home, it's likely that the hot water reaching your taps is heated bythe boiler. In other cases, hot water may be supplied by a stand-alone instantaneous water heater that's mounted near the fixture it serves.

Like many other household conveniences, a good supply of hot water is only truly appreciated when it stops. And if it stops when you're in the shower, this realization can arrive quite abruptly. Fortunately, it doesn't happen that often. The systems that provide hot water are generally reliable and operate for years without a hitch. But when the hitch comes, some background can help. Even if you can't make the repairs yourself, you'll have a good idea what to tell the doctor when he arrives.

A water tank is a container for storing liquid. The need for a water tank is as old as civilization, to provide storage of water for use in many applications, drinking water, irrigation agriculture, fire suppression, agricultural farming, both for plants and livestock, chemical manufacturing, food preparation as well as many other uses. Water tank parameters include the general design of the tank, and choice of construction materials, linings. Various materials are used for making a water tank: plastics (polyethylene, polypropylene), fiberglass, concrete, stone, steel (welded or bolted, carbon, or stainless). Earthen pots also function as water storages. Water tanks are an efficient way to help developing countries to store clean water.

An air handler, or air handling unit (often called an AHU), is used to condition and circulate air as part of an HVAC system. An air handler usually contains a blower, heating or cooling elements, filter racks or chambers, sound attenuators, and dampers.
A: Humidifiers help make dry air more comfortable by boosting your indoor humidity level. Typically, your humidity level - or the amount of water vapor in the air - drops during the colder months because cold air cannot hold as much moisture as warm air.
A vaporizer (steam humidifier, warm mist humidifier) heats or boils water, releasing steam and moisture into the air. A medicated inhalant can also be added to the steam vapor to help reduce coughs.
Though the sun emits all of the different kinds of electromagnetic radiation, 99% of its rays are in the form of visible light, ultraviolet rays, and infrared rays (also known as heat).

Electrostatic filters use an electrostatic charge to attract pollutants and trap them on collector plates. Electrostatic precipitators use electronic cells to charge particles within the purifier and immediately trap the impurities on collector plates. The main advantage with this type of air purifier is that the collector plates never have to be replaced; they can be easily washed in the dishwasher. But if the collection plates are not cleaned frequently, they quickly lose efficiency. Be aware that some electrostatic precipitators also generate ozone, which is a known lung irritant.

Studies by the EPA (Environmental Protection Agency) and other organizations have found that people spend as much as 90% of their time indoors. Today’s building construction practices means our homes and other buildings in which we spend time are more airtight and energy efficient than ever. As a result, we trap potentially irritating and harmful substances such as chemicals, odors, pollen, smoke, bacteria, mold spores, animal dander and numerous other irritants inside our homes. Various studies indicate poor indoor air quality has been linked to chronic diseases such as diabetes, asthma, allergies, cancer, Alzheimer’s disease, heart disease, high blood pressure, weight gain, internal organ damage and respiratory infections. Since studies of indoor air have found that air inside the home can be as much as 100 times more polluted than outdoor air, indoor air quality should be a concern for everyone. Young children and the elderly are most susceptible to poor indoor air quality.

Each person inhales over 3,500 gallons of air each day. Children inhale more particles for their size than adolescents or adults. The average person takes 20,000 breaths per day! Polluted air causes 94% of all respiratory problems. More than 31 million Americans have been diagnosed with asthma, about 1/3 are children under 18. About 40,000 dust mites, a common household allergen, can live in one ounce of dust. An estimated 10-15% of the entire population may be allergic to cat or dog dander. A person sheds up to 700,000 skin flakes per day. Indoor air pollution comes in 3 basic variations: Northlake, Illinois ac hvac rooftop units residentail and commercail heating and air conditioning free estimates experts, service repair and installation day and night
1. Particulates (35%): Particulates include: pet dander, dust, dust mites, asbestos dust, pesticides, pollen, post-fire ash, spray mist from aerosol products and more.
2. Gases (31%): Gases include: tobacco, paints, welding fumes, chemicals, varnishes, correction fluids, paint strippers, household cleaning products and more.
3. Germs (34%): Germs, mold, bacteria and viruses breed in consistently moist and / or unclean environments. They’re introduced into your home with water damage or when people enter your home.

There are many sources of indoor air pollution in any home. These include combustion sources such as oil, gas, kerosene, coal, wood, and tobacco products; building materials and furnishings as diverse as deteriorated, asbestos-containing insulation, wet or damp carpet, and cabinetry or furniture made of certain pressed wood products; products for household cleaning and maintenance, personal care, or hobbies; central heating and cooling systems and humidification devices; and outdoor sources such as radon, pesticides, and outdoor air pollution. Addison, Illinois ac hvac rooftop units residentail and commercail heating and air conditioning free estimates professionals, service repair and installation Frazier Johnstone
Some sources, such as building materials, furnishings, and household products like air fresheners, release pollutants more or less continuously. Other sources, related to activities carried out in the home, release pollutants intermittently. These include smoking, the use of unvented or malfunctioning stoves, furnaces, or space heaters, the use of solvents in cleaning and hobby activities, the use of paint strippers in redecorating activities, and the use of cleaning products and pesticides in house-keeping. High pollutant concentrations can remain in the air for long periods after some of these activities.You should first consider a variety of factors when selecting the air cleaner that best suits your needs, such as: Bensenville, Illinois ac hvac rooftop units residentail and commercail heating and air conditioning free estimates specailists, service repair and installation Frigidaire

In "event-based" air cleaning, you can control your air cleaner to clean the air in your home even if the HVAC system is not heating or cooling. How do you do this? By simply turning the blower fan in your HVAC system on when the heating and cooling function is off. This keeps air flowing through your air cleaner at all times, whether heating, cooling or simply running the blower fan. Why would you want to do this? Maybe the outdoor seasonal pollen has made its way inside and is causing an increase in allergy or asthma triggers. Maybe someone in your home has a chronic health concern that requires constant air cleaning. Maybe you are remodeling and demolition particles from drywall, wood, insulation and other sources are everywhere!

Companies may advertise "Event-Based" air cleaning as if it's new, special or unique technology. The fact is ALL whole house HVAC-installed air cleaners (including GeneralAire®) are capable of event-based cleaning; either manually (by simply turning your fan on at the control unit / thermostat) or automatically (with a programmable control unit / thermostat). If you wish to use a thermostat for automatic control, be sure it is one designed to program your heating, cooling and fan operations.

Air is cleaned by an HVAC-installed air cleaner while the HVAC system is on (actively heating or cooling the house, or while the blower fan is on) because it moves air through the air cleaner filtration system. As the air passes through the air cleaner and the filter media within, it traps the unwanted particulates, allergens and contaminates. The air leaving the air cleaner after passing through the filter is free of particulates, allergens and other harmful contaminants. UV Purifiers (as found inside the TERSus Air Cleaner) utilize germicidal irradiation like the sun outdoors to eliminate mold, bacteria, germs and viruses from the air.

Not completely. There will always be some dust that settles on furniture, as is it is too heavy to stay airborne and travel through your air cleaner. To ensure your air cleaner is providing the greatest benefit, either run it continuously or run it often to keep air circulating through the air cleaner. Be sure to change your air filter media as recommended; or in the case of an electronic air cleaner, clean it per the recommended intervals. Be sure to use authentic GeneralAire® replacement filter media.A flue lining in a masonry chimney is defined as "A clay, ceramic, or metal conduit installed inside of a chimney, intended to contain the combustion products, direct them to the outside atmosphere, and protect the chimney walls from heat and corrosion." Although building codes vary from one state or locality to another, the installation of flue lining has been recommended since the early part of this century, and indeed most fire codes now mandate liners. Elk Grove , IL ac hvac rooftop units residentail and commercail heating and air conditioning free estimates fixing, service repair and installation Payne In the 1940's and again in the 1980's, masonry chimneys were tested by the National Bureau or Standards for durability due to rising concerns about their performance and safety. The tests revealed that unlined chimneys were so unsafe that researchers characterized building a chimney without a liner as "little less than criminal".
Liners in chimneys serve three main functions:
1) The liner protects the house from heat transfer to combustibles. In the NBS tests, unlined chimneys allowed heat to move through the chimney so rapidly that the adjacent woodwork caught fire in only 3 1/2 hours. Evanston IL ac hvac rooftop units residentail and commercail heating and air conditioning free estimates cleaning service repair and installation Rheem
2) Liners protect the masonry from the corrosive byproducts of combustion. In the tests it was determined that if the flue gases were allowed to penetrate to the brick and mortar, the result would be a reduction in the usable life of the chimney. The flue gases are acidic in nature and literally eat away at the mortar joints from inside the chimney. As the mortar joints erode, heat transfers more rapidly to the nearby combustibles and dangerous gases such as carbon monoxide can leak into the living areas of the home. Glencoe, IL ac hvac rooftop units residentail and commercail heating and air conditioning free estimates checking, service repair and installation Tappan
3) Liners provide a correctly sized flue for optimum efficiency of appliances. Modern wood stoves and gas or oil furnaces require a correctly sized flue to perform properly. The chimney is responsible for not only allowing the products of combustion a passage out of the house, but the draft generated by the chimney also supplies the combustion air to the appliance. An incorrectly sized liner can lead to excessive creosote buildup in woodburning stoves, and the production of carbon monoxide with conventional fuels.Chimney liners come in three main types: Clay Tiles, Metal, and Cast-in-place, Glenview, IL ac hvac rooftop units residentail and commercail heating and air conditioning free estimates replacements service repair and installation Tempstar
1) Clay tiles are the most common type of masonry chimney liners. They are inexpensive, readily available, and perform quite well for open fireplace chimneys that are properly maintained. There are two disadvantages to clay tiles. The first is that, being a ceramic product, they cannot rapidly absorb and evenly distribute heat during the rapid temperature rise that occurs during a chimney fire. This uneven heating produces an unequal expansion which in turn causes the flue tiles to crack and split apart. This is similar to immersing a cold drinking glass in very hot water. It will instantly shatter. A chimney with cracked chimney liners must be repaired before use. The second disadvantage is that tiles cannot adequately contain the liquid combustion byproducts produced by modern gas appliances. Arlington Heights, IL ac hvac rooftop units residentail and commercail heating and air conditioning free estimates installations, service repair and installation Trane
2) Metal chimney liners, usually of stainless steel or aluminum, are primarily used to upgrade and repair existing chimneys. These liner systems are U.L. tested and listed, and if properly installed and maintained are extremely safe and durable. Stainless steel is suitable for woodburning, gas, or oil applications, while the aluminum is an inexpensive alternative for certain medium efficiency gas applications only. It is usually required that high temperature insulation be used in conjunction with the liners for safety and performance considerations. Buffalo Grove ac hvac rooftop units residentail and commercail heating and air conditioning free estimates air conditioning service repair and installation Weather King
Cast-in-place chimney liners are lightweight, castable, cement like products that are installed insidethe chimney forming a smooth, seamless, insulated passageway for the flue gasses. They can improve the structural integrity of aging chimneys, and are permanent liners suitable for all fuels.

Considering the dangers of old unlined or damaged chimneys, and the many cost effective options now available to make these chimneys safe components of the home heating system, may we suggest you have your chimney professionally inspected to be sure it meets modern safety standards.

Falling Debris
Bits of brick or mortar debris falling down the chimney flue indicates a decay in its structure. The debris could be small pieces of brick, sand, tar or soot or lumps of mortar. This problem can be easily fixed by patching or replacing old broken bricks, and re-tarring the flue. Evanston, IL ac hvac rooftop units residentail and commercail heating and air conditioning free estimates professionals, service repair and installation American Standard
Heated Chimney Openings
When the chimney openings in adjoining or above wall heats up, it is a sign of flue deterioration. A common symptom of this problem is dull black stains that begin to appear on its opening, caused due to condensed tar or acids in the flue, that are damaging to the brickwork of the chimney. Glencoe, IL ac hvac rooftop units residentail and commercail heating and air conditioning free estimates specailists, service repair and installation Ameristar
Not Enough Fire
When fire is not drawn adequately, it is caused due to obstructed flue or when the height of the chimney is insufficient in relation to the ridge of the roof. However, just increasing the height of the chimney will not alone help to draw out enough fire, and it needs to be combined with clearing the flue obstruction. Elk Grove , IL ac hvac rooftop units residentail and commercail heating and air conditioning free estimates fixing, service repair and installation Payne
Fumes in the Rooms
Chimney fumes containing carbon monoxide (CO) is dangerous and capable of killing. Even lower levels of CO concentration can cause dizziness, mental confusion, severe headaches, nausea and fainting. Many times, a leaky chimney will send fumes all over the house. This kind of a problem requires the immediate attention of a qualified technician. Glenview, IL ac hvac rooftop units residentail and commercail heating and air conditioning free estimates maintenance, service repair and installation Arcoaire
Excessive Soot
When the flue is not of appropriate diameter for the fire or stove, or at times, when the fumes does not rise rapidly, it can create soot deposits. Soot deposits are particularly hazardous, if the chimney structure has deteriorated. Ensuring that the flue is of correct diameter, will reduce collection of soot. Harwood Heights, IL ac hvac rooftop units residentail and commercail heating and air conditioning free estimates repairman service repair and installation Armstrong
Too Much Fuel
Uninsulated flues require a lot of fuel to draw heat. When small outlet fume pipes, discharge into large uninsulated flue, they won't rise up. To accelerate their ascent, they consume more fuel. An insulated flue of the correct size will solve excess fuel consumption problems. Dampness in the Chimney, Highland Park, IL ac hvac rooftop units residentail and commercail heating and air conditioning free estimates technicians, service repair and installation Bryant A damp chimney will stain the ceiling and the chimney opening, as well as walls around the fireplace.

Chimneys need to allow free passage of dangerous combustion gasses. Regular cleaning will remove soot and creosote, helping prevent dangerous chimney fires. Cleaning will increase the efficiency of some appliances. Bird nests, cobwebs and other blockages will be removed.

A simple way to keep other animals and birds out of a chimney is a top-sealing damper. When you are not using your fireplace, you can securely close a top-sealing damper with a pull on a chain located inside your fireplace. Not only can birds and other animals not get in, but also cold air doesn't enter your home during the winter and air conditioned air doesn't escape during the summer. This sure-fire way to keep birds out of the chimney is a cost-effective and energy-saving investment in your home, not to mention never again having to worry about a bird lose in your home or unwelcome bird nests in the chimney. Lincolnwood, IL ac hvac rooftop units residentail and commercail heating and air conditioning free estimates servicing, service repair and installation Comfortmaker
Another choice is whether to do it yourself or bring in a chimney sweep to remove bird nests from a chimney. Some chimney bird nests can be easily removed by any homeowner willing to go up on the roof. Others, such as barn swallow nests, require scraping off the nest from the interior of the chimney, a messy process that can drop unsanitary and possibly mite-infested material into your fireplace. If you do this type of bird nest removal yourself, we suggest you take your shop-vac to the roof and use it to catch bird nest debris as you remove it. Morton Grove, IL ac hvac rooftop units residentail and commercail heating and air conditioning free estimates trouble shooting service repair and installation Concord
Whether you remove the chimney birds nest yourself or hire a chimney sweep to do it, it is imperative to remove any nests or remaining nesting materials before your use your fireplace in the fall. Combustible material inside your chimney flue and a burning fire are not a good combination! Mount Prospect, IL ac hvac rooftop units residentail and commercail heating and air conditioning free estimates repairing, service repair and installation Daikin
This depends a lot on how much you use your fireplace or stove. The National Fire Protection Association says, "Chimneys, fireplaces, and vents shall be inspected at least once a year for soundness, freedom from deposits, and correct clearances. Cleaning, maintenance, and repairs shall be done if necessary." So, even if you don't use your chimney a whole lot – birds, squirrels, raccoons and other critters may have been using your chimney making it unsafe to use without clearing out the accumulated debris from nesting activity. North Mayfair, Chicago, IL ac hvac rooftop units residentail and commercail heating and air conditioning free estimates trouble shooting service repair and installation Westinghouse
The CSIA (Chimney Safety Institute of America) says that fireplaces should be cleaned when 1/8″ of sooty buildup is evident inside the chimney and flue system. If any glaze is appearing in the flue, cleaning should be done even if there is less than 1/8″ of build up. Any time an appreciable accumulation of soot and creosote occurs it can be enough to fuel a chimney fire that may damage the chimney and even spread to the roof and home. Furnace flue systems also require cleaning, so don't neglect regular cleaning of those venting systems.

Some heavy use fireplaces produce an incredible amount of soot and creosote during a cleaning. Recently we removed nearly 2 full 5 gallon buckets of material from one chimney! Removing this material is critical to continued safe use of the fireplace and reduced risk of chimney fires that start when this highly combustible material builds up to unsafe levels.Expansion Tanks for Water Heaters. An expansion tank prevents pressure increases due to thermal expansion of your water. As your water is heated from 50° F to 120° F, it expands by approximately 2%A low-water cutoff is a mechanical device (usually a float switch) that is used to turn off the burner or shut off fuel to a boiler to prevent it from running once the water drops below a certain point. If a boiler is "dry-fired" (burned without water in it) it can suffer rupture or catastrophic failure. Winnetka, IL ac hvac rooftop units residentail and commercail heating and air conditioning free estimates specailists, service repair and installation Trane
The cause of low-water cutoff device failure is usually lack of maintenance, incorrect maintenance or improper modification.Low-water cutoff devices for boilers are one of the most important safety devices. These devices are installed on most steam heating boilers and also on many hydronic or "hot water" heating boilers as a safety device to shut down the boiler in the event of loss of water in the system.The device's function is simply to prevent boiler operation in low-water conditions once it detects liquid levels dropping. These are relatively simple mechanisms; their purpose is to shut off fuel to the fire when the water level drops below a safe operating level. This is accomplished either mechanically or electronically. Without a properly functioning low-water cutoff, the burner can continue to fire, allowing for intense heat to build. The results can be catastrophic — explosions, fires and the possibility of severe injuries to personnel and property. Norridge, IL ac hvac rooftop units residentail and commercail heating and air conditioning free estimates checking, service repair and installation Fraser Johnstone Low-water cutoff device failures are easy to prevent. Indicators of failure include:
Physical signs of poor maintenance Very low blowdown frequency Sediment buildup Rough or erratic function in boiler componentsHydronic (hot water boilers) in proper condition do not normally consume any water. Once the boiler and the baseboard, radiator, or convector piping are connected and filled with water, that same water remains in the system indefinitely. The water in the boiler is heated and circulated through the occupied space to provide heat to the building occupants. Northbrook, IL ac hvac rooftop units residentail and commercail replacements service repair and installation Frigidaire
Water may be lost from a hot water heating system, however, due to a small leak that may be un-noticed, or water may be removed from the system during servicing.Some older heating systems may not have an automatic water feeder and may only provide a manually operated valve to add water to the boiler. To maintain the water level in these heating systems, water can be added from the building water supply piping manually by simply opening a make-up valve. A manual valve will simply be a shutoff valve that can be opened by hand to force water into the heating boiler.On many heating boilers the expansion tank and water feeder valve are separate physical units. Wicker Park, Chicago, IL ac hvac rooftop units residentail and commercail heating and air conditioning free estimates furnace service repair and installation Lennox
On these older systems the "automatic water feeder" is often a bell-shaped device which opens and sends makeup water into the heating boiler and its piping whenever the heating system's internal water pressure falls below a normal level (perhaps 12 psi when the boiler is cold). In our photo at left the gold colored bell-shaped device pointed to by the red arrow is an automatic pressure-reducing & water feed valve for a hot water boiler. An arrow cast into the valve base shows the direction of water flow (from building supply at right into the boiler at left in this photo). Palatine, IL ac hvac rooftop units residentail and commercail heating and air conditioning free estimates installations, service repair and installation Gibson
The screw and lock nut on top of this valve permit adjustment of the automatic water feeder valve pressure (it's normally set to 12 psi).The horizontal lever is a bypass that will send water through the valve on to the boiler at full building pressure (it's normally left "off" in the position shown here).The separate heating system backflow preventer / check valve indicated by our green arrow in the photo above is discussed in more detail
at BACKFLOW PREVENTER VALVE, HEATING SYSTEM .The device to the right of the automatic pressure reducer (water feed valve) in our photo above is a back-flow preventer that is required in some municipalities. The back-flow preventer makes sure that water from inside the heating boiler cannot flow backwards into the building (and community) water supply. This prevents back-contamination of potable water piping from the boiler should the building water pressure fail.The automatic water feed valve reduces the incoming water pressure from the building supply side down to (typically) 12 psi. That's because the normal in-boiler water pressure, when the heating boiler is cold, is about 12 psi in a normal residential system. A tall building may need to start with higher cold-system water pressure to be able to push hot heating water to upper floors. Wilmette, IL ac hvac rooftop units residentail and commercail heating and air conditioning free estimates professionals, service repair and installation Payne
The water feed valve adds water to the boiler when needed: If water pressure in the heating boiler drops below 12 psi, the water feeder valve will add makeup water to the system automatically, until it reaches 12 psi inside the boiler. So is the B&G Pressure Reducer an Automatic Water Feed Valve or Not? Wheeling, IL ac hvac rooftop units residentail and commercail heating and air conditioning free estimates heating and air conditioning free estimates experts, service repair and installation Maytag
Well yes, and no. The valve can automatically feed water into a hot water heating boiler whose pressure falls below the set-pressure (12 psi at factory setting) if the water shutoff valve for the boiler has been left "on".The B&G pressure reducing valve shown at left includes a bypass lever shown in the "up" or "open" position in the illustration. In this position water is fed into the boiler at street pressure. When the valve is "down" in the "closed" position, IF the shutoff valve before the pressure reducer is open, water is fed to the boiler if its pressure drops below the valve's pressure setting (adjusted by the lock-nut and screw on the valve top). Park Ridge, IL ac hvac rooftop units residentail and commercail heating and air conditioning free estimates air conditioning service repair and installation Goodman
But the manufacturer warns that the purpose of the pressure-reducing (and automagic water feeding) valve is to fill heating boilers after installation or servicing. The company saysIt is not a safety device and is not intended to be used as as a water feed valve to control boiler water at a safe operating level".OPINION: this is interesting since for closed-system hydronic heating boilers (not steam boilers) that's how lots of service techs and inspectors view this device. Skokie, IL ac hvac rooftop units residentail and commercail heating and air conditioning free estimates cooling service repair and installation luxaire
In the company's service manual you'll see on the installation piping sketch (edited) for the pressure reducing valve (green, to the right of the blue shutoff valve at the left side of the sketch below) that they expect the installer to include a water shutoff valve (blue at the left end of the sketch below) before this pressure reducer.B&G wants you to keep the boiler water supply valve shut except during service - as a precaution that allows easy detection of a boiler leak by noticing the reduced water pressure in that system. The company also points out that too-frequent feeding of water into a heating system can increase the effects of corrosion and system damage. Prospect Heights, IL ac hvac rooftop units residentail and commercail heating and air conditioning free estimates heating service repair and installation Heil
In my [DF] opinion, a typical building owner or occupant almost never thinks to check the water level in a hydronic heating system (hot water boiler) until there is some indication of a problem (like no heat or a damaged leaky boiler). In our experience most hydronic heating boiler installers and service techs leave that shutoff valve "open" or "on" so that the boiler won't be at risk of being ruined or unsafe by operating at low or no-water level - their experience may be similar to mine. The manufacturer is telling you what's safe in some regards, but they may not have the same view of what people actually do in the field.
