Radiant hot water heater windows#
Radiant floor heating does not blow air from one room to another, so less heat is lost from air infiltration and through windows or walls. (This is especially an asset in bathrooms, for people with poor circulation, and is a hit with the cat and dog.) The floor surface temperature can be adjusted to adapt to any floor covering. The floor becomes the warmest surface in the room, not the coldest. Heat from the floor warms all the mass in your rooms, giving every surface an inviting sensation that you can feel. The system is usually coordinated with the domestic water heating, with a heat exchanger separating potable water and the heating system. Typically, a gas-fired tank-type water heater, instantaneous water heater, geothermal heat pump, or boiler is used, but the backup can be any type of heater, using whatever fuel is locally available. A backup heat source is installed for times when solar heat has been insufficient. This makes radiant floor heating a good complement to active solar water heating. This means the water only needs to be about 90-110 degrees - not boiler hot - for floor heating to work. The larger the radiating surface, the lower the temperature difference needed to transfer heat. It is a good complement to passive solar design because both systems work well with building on an insulated slab, providing mass for passive heat storage and a convenient and protected location for the pipes. Radiant floor heating uses warm fluid (usually water) running through pipes imbedded in or attached to the floor to heat space. We work with H1 licensed heating contractors, including Select Heating and Air, Bowman Mechanical, Evangelist Geothermal, and others, to design and coordinate these installations. The staff of Solar Consultants has years of experience integrating solar input with space heating systems. Radiant floor heating, because of the large heating surface working at a relatively low temperature, is the best way to use active solar and geothermal (ground source heat pumps) in building heating.
