American 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.

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.
American 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.
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.
American Services HVAC installation in St. Louis knows that in the last 5 years there has been a significant impact in the zoning market based on new technology.
Below is a sample of the latest products and systems available to suppliers and contractors involved in zoning system design, installation, maintenance and service.
Zone control dampers are offered already attached at the factory. A transformer Rated at 120, 24 volts comes complete with the damper. This damper comes with a power open, power close motor. And features LED light, both red for closed and green for open damper status. Also provided is the wireless thermostat that is available in programmable or non programmable versions.
Other optional mounted controls are available through Jackson systems. These controls can be combined, and mated with the Piro sensing and occupancy controller.
Technology has come up with a residential and light commercial geothermal zoning system called the GTPro. The system allows for additional flexibility with three staging options including; time, temperature and number of rooms. This unit will analyze indoor and outdoor air temperatures, monitor loop temperature and multi point thermostat data which maximizes service efficiency, operational control and comfort. In addition humidity controls allow for contractors to make adjustments for different reasons or climates. The unit also allows for the contractor to have multiple configurations on additional relays for assorted application customization schemes.
Another option is the DA2. This damper is based on the Belimo MP Bus Platform. This is a proportional damper/valve actuator. The camper is programmable to communicate wirelessly with Can2Go controllers. Wireless operations reduce wiring and down time cost. Some experts say it is optimal for HVACs applications such as retrofitting water based central heating system, geothermal systems, most chillers and cooling tower installations, radiant floors and chilled slabs.
