While it is true that radiant floor systems operate at much lower temperatures than radiators and warm air systems, the requirement to heat the mass of the home as well as the air space in it dictates a higher need for energy. Imagine for a moment that you need to heat a cup of water without heating the cup. If this scenario was a forced air system, then heating the same water in a radiant floor system would be like heating the same cup of water where the cup is made of concrete.
Many customers ‘moving up’ to radiant floor heated houses have typically moved from other homes with less comfortable heating systems, which is often the driving force for selecting radiant floor. Once that constant warmth is felt, customers tend to have the heat on more, quite the contrast from other systems which get turned on and off as needed. This is one of the key determinants in the amount of energy consumed in radiant floor heated homes. As such, comfort requires expense.
We have been designing and installing radiant floor and a variety of hot water heating systems for the last 30 years. Our expertise can build the system you want, or help you troubleshoot and rectify a system you are having problems with. As this site develops, we will look at the pros and cons of various options and design concepts. Happy Heating!
