Radiant Floor Heat
Radiant floor heat has become a popular supplement of traditional heating systems. Used in this manner, it can help maintain a more constant indoor temperature with a possible savings in energy bills. The spacing of the water-filled tubing or electric heat elements produce a consistent amount of heat from the floor level. It uses the entire floor as a radiator, surrounding people and objects with warm air near the floor. The heating source for the water can be as simple as a traditional water heater. For larger applications, a boiler might be a consideration.
There are a number of different applications that can be used. For new construction, the water tubing can be installed above the sub-floor (as seen below). For existing homes, the tubing can be installed in the joist-spaces below the floor. Insulation is then placed beneath that tubing to project the heat upwards towards the floor to be heated.
How Does Radiant Heating Work?
Radiant heating is achieved by placing plastic tubing above the subfloor and covering it with an underlayment. Heated water is run through the tubing to make your floor a super-efficient radiator.
Conventional duct systems allow heat to collect where it's most likely to escape - at the ceiling and along outside walls. With Infloor radiant heating, the temperature throughout the room remains nearly constant because heat is dispursed evenly across the floor. This factor alone reduces heat loss up to 25% when compared to similar homes using conventional heating methods.
