Commercial Warm Air Heating

Commercial Warm Air Heating

heating equipmentIn the heating and cooling world of which we are a part, we try to bring to you some of the latest information on behalf of your Heating Installation in St Louis near O Fallon MO.  Some of the most intriguing data comes from subjects that are somewhat fundamental, yet mysterious to most, such as how heating systems actually operate. Today, we will talk about the two main types of heating systems:  warm air and radiant heating in St Louis near O Fallon.

Warm air heating is classified as the first type of heating system and makes use of fan to draw air across a heat exchanger, which increases the temperature of the air and distributes it evenly throughout an area or space. These are ideal for environments requiring constant temperature.  The process involved here is for a warm air heating commercial system in St Louis and starts from a gas or oil fired burner as the initial source of warm air.  Then, hot water circulates throughout the heat exchanger or the electric element.

How are these particular heaters in St Louis installed?  Well, they can be situated by suspending them above the space being heated or mounted on the walls or even on the floor.  For those of you heating a commercial space who need to resort to the floor installation, the following may be important to note, “The floor standing models may use outlets to direct the warm air to specific areas or they can be directed to a duct work system to distribute the warm air to a bigger area. The choice will depend on the floor area or layout of the space.”  There is more to discuss here, regarding the warm air heating process and specifics on how these particular heaters work.  Stay tuned for future posts on the subject on behalf of your St Louis Heating Installation near O Fallon MO.

Radiant Heating in Commercial Environments

Radiant Heating in Commercial Environments

radiantWe recently set out to discover the types and ways in which it is best to heat a commercial space in St Louis near Belleville IL.  We found that there are two main styles of heating and that after you understand the area that you are attempting to heat or cool, you will likely be able to better decide which way works best for the space in question.

The first type, which we went into pretty good details over in the previous post here on behalf of your St Louis Heating and Cooling installation and sales near Belleville, is referred to as warm air heating.  Ideal for areas that require a more constant temperature, these commercial heating set ups are usually started with a gas or oil fired burner as the source of heat, then hot water is typically circulated through the heat exchanger or an electric element from there.  There are floor models or those that can be suspended above the space in being heated by your St Louis Heating Service near Belleville.

“The floor standing models may use outlets to direct the warm air to specific areas or they can be directed to a duct work system to distribute the warm air to a bigger area. The choice will depend on the floor area or layout of the space.”  Radiant heating is yet the other type of heating in St Louis near Belleville IL and it is a popular way to heat commercial space as well.  Typically provided by radiant tubes that are placed in built-in duct work throughout the roof, the radiant plaque heaters are sometimes used there instead.  In either case though, according to our St Louis Heating sales near Belleville IL, the heat energy is emitted in the form of infrared radiation from the hot surfaces of the heaters. The infrared radiation warms the people or occupants and other objects exposed to it.

Types of Heating Systems for Commercial Buildings

Types of Heating Systems for Commercial Buildings

industrial heating maintenance in MOAmerican Services industrial heating equipment installation near Wood River knows that there are many types of efficient heating systems to select from for commercial buildings. Examples are; radiant heating, eat pumps, radiators, and more.

Radiant heating systems function by supplying heat directly to the floors or to wall or ceiling panels of your commercial building. Radiant heating systems depend on transfer of heat or delivery of heat directly to objects in the room. This type of radiant heat is called “infrared radiation.”

Radiant heating is far more efficient than baseboard heat or forced air because there is no loss of heat through the duct system that forced air must travel through before entering the room it is heating.

Steam radiator systems are another option of heating for commercial spaces.  Steam radiators utilize  a boiler which actually heats water to a boiling point into steam.  This steam then moves through the pipes and it does not require pumping. One drawback to steam heating is that it requires a period of time before the system is hot enough to heat the room.

Heat pumps are yet another type of heating source and it can be a liquid or air source. Liquid heat pump systems are usually made up of several heat pump units located above the ceiling tiles on each floor of a high-rise building. A water loop is required to provide heat to the refrigerant at the heat pumps. The water loop then collects more heat which  is usually from a boiler inside the building.

No matter what type of efficient heating system you choose for your commercial building, contact us today at American Services.  We can help you with installation and maintenance of any heating service select.

Alternative Heating Sources

Alternative Heating Sources

solor heating in MOAmerican Services Heating and Cooling installation service in Missouri knows that there are many options when it comes to commercial heating systems.

One such option is for heat transfer fluids.  If you are considering solar heating heat transfer systems, be sure to consult the local authority in your area to find out what exactly is required for your geographic area.

Water is one type of substance that is effective as a heat transfer fluid, particularly with its low viscosity property which makes it easy to pump. Drawbacks are its low boiling point and high freezing point, and the fact that water can be corrosive and cause mineral deposits.

Glycol and water mixtures are made up of a 50/50 or 60/40 glycol-to-water ratio. Ethylene and propylene glycol make up the properties of antifreeze.

Hydrocarbon oils have a higher viscosity and lower specific heat than water meaning they need more energy for circulation.  With a low freezing point, these types of oils tend to be relatively less expensive than some others.     The basic categories of hydrocarbon oils are synthetic hydrocarbons, paraffin hydrocarbons, and aromatic refined mineral oils. Synthetic hydrocarbons are relatively nontoxic and require little maintenance. Paraffin hydrocarbons have a wider temperature range between freezing and boiling points than water, but they are toxic and require a double-walled, closed-loop heat exchanger. Aromatic oils are the least viscous of the hydrocarbon oils.

Refrigerants are commonly used in refrigerators, air conditioners, and heat pumps as the primary heat transfer fluid. They generally have a low boiling point and a high heat capacity which enables a small amount of the refrigerant to transfer a large amount of heat very efficiently.

If you currently own a refrigerant-charged solar system that requires maintenance, contact us today at American Services and we will sent out a qualified technician.

Active solar heating uses solar energy to heat transfer fluid or air, which then transfers the solar heat to an interior  storage system for later use. Solar heating systems can be implemented as a supplement to other heating systems such as radiant heating, boilers, heat pumps, or forced-air heating systems.

Active solar heating systems are actually most cost-effective in cold climates that have good solar resources.  Liquid and air systems are good choices for forced air supplemental heating. Note that commercial systems usually come with warranties of 10 years or more and usually last much longer.

Radiant Heating Panels

Radiant Heating Panels

industrial heating service in MOAmerican Services heating installation service in Saint Louis MO knows that when it comes to alternative sources of heating, there are many choices available for commercial spaces.

One example is wall and ceiling mounted ceiling panels which are comprised of aluminum and can be heated with electricity. Another heating option for heating panels is to utilize tubing which carries hot water.  The disadvantage of hot water tubing is the concern for water leaks inside the walls or ceilings-thus most commercial radiant panels are electrically heated.

Radiant panels can cost a lot to operate but they can supply supplemental heating supply for individual rooms or can be used when conventional heating systems are not an option.

The advantage to radiant panels is that they have the fastest response time of any other heating method and the panels can be individually controlled in every room.  Using this heating method for rooms that are infrequently used can provide overall cost savings and a fast method of heating rooms to a comfortable temperature within minutes.  These systems should be set to on the minimum heat settings to prevent pipes from freezing in geographic areas where subzero temperatures occur.

“Radiant heating panels operate on a line-of-sight basis — you’ll be most comfortable if you’re close to the panel. Some people find ceiling-mounted systems uncomfortable because the panels heat the top of their heads and shoulders more effectively than the rest of their bodies,” says Energy.gov.

Radiant Cooling for Office Buildings

Radiant Cooling for Office Buildings

radiant cooling service in MOAmerican Services heating and cooling service in Saint Louis knows that most radiant cooling systems are based on aluminum panels that are extended from the ceiling through which cooled water is circulated.

In order for this system to effectively cool the office area, panels must be kept at a temperature near the dew point within the office building and the interior space must be dehumidified.  Condensation will occur in humid climates where radiant cooling systems are utilized, even when there are brief periods of exposure to the outside air within the office space. An auxiliary air conditioner may be needed to keep the humidity level low enough.

Where the climate is arid, such as in the southwest, these radiant cooling systems are advantageous particularly in the ceilings of adobe buildings where the inside air can be maintained at a steady cool temperature.

Offices built on concrete slabs are also considered some of the best candidates for radiant cooling, using the same principal as ceiling systems with chilled water systems in the floor, as well as radiant heating systems.  This option is a great choice particularly with office spaces that have existing radiant floor systems.  Humidity continues to be a concern with radiant floor cooling systems, particularly on floors that have carpet coverings instead of the preferred choice for radiant cooling systems-which is ceramic tile.  Condensation is common in areas with heavy carpet, which also limits the temperature at which the floor can be lowered to.

These systems can be very cost effective even when utilized with auxiliary cooling systems which can be used at off peak hours, reducing overall electricity demand for the business.

Forms of Radiant Heating Available

Forms of Radiant Heating Available

heating repair in MOAmerican Services heating and cooling repair in St. Louis knows that as it is stated on the website energy.gov, “Radiant heating has a number of advantages.” It is more efficient than baseboard heating and usually more efficient than forced-air heating because it eliminates duct losses. People with allergies often prefer radiant heat because it does not distribute allergens like forced air systems can. Hydronic (liquid-based) systems use little electricity, a benefit for buildings off the power grid or in areas with high electricity prices. Hydronic systems can use a wide variety of energy sources to heat the liquid, including standard gas- or oil-fired boilers, wood-fired boilers, solar water heaters, or a combination of these sources.”

One type is air-heated radiant floors. Since air can’t hold large amounts of heat, air-heated floors are not cost-effective in residential construction. Sometimes they can be combined with solar air heating systems. However in these situations, heat is only produced in the daytime. It is inefficient to attempt to heat a home with a conventional furnace by pumping air through the floors at night, even with the benefits of using solar heat during the day.

Hydronic systems can use a wide variety of energy sources to heat the liquid, including standard gas- or oil-fired boilers, wood-fired boilers, solar water heaters, or a combination of these sources.” . Electric radiant floors can also be used for home additions if it would be difficult to use the existing heating system in the new space,

Hydronic, or liquid-based, systems are the most widely used and cost-effective radiant heating systems for in cooler climates. Hydronic radiant floor systems pump heated water from a boiler through tubing laid underneath the floor. Hydronic radiant heat is certainly a topic that can be an efficient energy option for builders to use in a variety of different construction scenarios.

Radiant Cooling

Radiant Cooling

cooling installation in ILAmerican Services heating and cooling installation in Jefferson County is committed to keeping customers updated on the latest in savings on commercial heating and cooling.

Is radiant cooling an appropriate technology to use in commercial buildings in the Northwest?

Researchers say the bottom line is that yes, radiant cooling can be a very cost effective means of cooling commercial buildings in most climates. Evidence suggests that applied properly radiant cooling could save significant energy in the commercial building sector, and may even increase occupants comfort, improve indoor air quality, and increased productivity.

A radiant cooling system works on the same principle as radiant heating, in fact in many cases the same network of piping as the heating system can be utilized. Basically the idea is that thermal comfort is determined not only by the temperature of the air around you, but a combination of the ambient air and heat being radiated to or from objects nearby.

A fairly large surface which is exposed to the building’s occupants must be cooler than the ambient air to provide radiant cooling. Occupants then radiate heat to the object causing a sense of cooling.  In practice, cooling is accomplished by chilled water circulating in an intricate network of pipes in panels or building components. Technically infrastructure can be in the floor, walls, or ceiling.

Radiant floors are popular for heating but have not been as successful for cooling because of condensation and other technical problems encountered. Walls are often not strategically located to give even heating to all occupants. Therefore the most popular choice has been ceilings thus far.The most common approach has been to use ceiling panels which makes the system modular, relatively easy to design, modify and repair.

Commercial Radiant Heating

Commercial Radiant Heating

American Services heating installation in Missouri knows that radiant heating systems basically involve supplying heat directly to the floors or to panels in the wall or the ceiling of your commercial building. These systems largely depend on radiant heat transfer, the delivery or transfer of heat directly from a hot surface to the people and objects in the room this is called “infrared radiation”

There are a number of advantages associated with radiant heating. Far more efficient than baseboard heating, and generally considered more efficient than forced air heating, radiant heating has no energy lost through the ducting system. This lack of moving air can also be advantageous to people with allergies. Hydronic or liquid based systems use little energy. Ideal for those homes off the power grid or high energy rate locations.
These systems can be heated with the wide variety of energy sources including standard gas and oil, wood fired boilers, solar water heaters, or a combination of all or some of these.
There are three types of radiant floor heat:
1. Radiant air floors
2. Electric radiant floors
3. Hot water radiant floors
these three radiant heat processes can be broken down further into type of installation.
1. Wet installations
2. Sandwich installations
3. Dry installations

Air heated radiant floors;
because air is incapable of containing large amounts of heat
Radiant air floors are not cost effective in residential applications. Solar heating systems can be used to offset these inefficient methods.

Electric radiant floors;
Electric radiant floors consist of electric cables built into the floor itself. Systems that feature mats of electrically conductive plastic are also available on the market and are mounted onto the subfloor below a floor covering such as linoleum or tile.
Because electricity is involved the relatively high cost of energy should be considered before selecting this floor heating design.

Hydronic systems are by far the most popular cost effective radiant heating systems. Radiant floor systems pump heated water from a boiler thru tubing laid in a pattern underneath the floor. In some of these systems the temperature in each room is controlled by regulating the flow of hot water through each loop. This is accomplished by a network of zoning valves or pumps and thermostats.

Green HVAC Alternatives

Green HVAC Alternatives

HVAC services in MOAmerican Services HVAC installation in St. Louis knows that energy experts say saving energy with a “green HVAC system” can help reduce your overall heating and cooling costs by 30 percent or more. HVAC contractors warn the do-it-yourself enthusiast that the green HVAC system should be installed by professional Personnel such as American Services.

With heating and cooling services responsible for up to 50 percent of energy bills, the efficient green HVAC system is rapidly becoming a critical requirement in both residential and commercial buildings.

Most HVAC systems were installed before 1992 and rated at 10 SEER (Seasonal Energy Efficiency Ratio) or less. These aging HVAC units continued to drop in SEER ratings year after year. Finally in an effort to increase the efficiency of HVAC systems the Department of Energy mandated and increased minimum SEER ratings from 10 to 13 in 2006. Today manufacturers of HVAC equipment are producing green high-SEER HVAC systems with ratings of 20 SEER or greater.

Replacing the pre-1992 HVAC system with the green HVAC System technology today could reduce your heating and cooling energy costs by up to 50 percent of your total energy bill.
Industry experts recommend replacing traditional HVAC systems with similar ‘green’ high SEER units to dramatically reduce energy costs.

New HVAC industry technology has produced non-traditional HVAC techniques. These technologies are developing quickly, and may be a better suited application for your commercial installation requirements than the efficient Green HVAC system.

Some of those non-traditional solutions are:
1. Automated ducting
2. Evaporative and indirect cooling
3.Geothermal heating
4, Thermal storage
5. Radiant heating and cooling
