How much more efficient is a radiant heat system than a forced air system?
A8) A typical forced air system requires 45-50 BTUs per square foot to maintain the temperature in a standard home (This does not account for the efficiency or inefficiency of the heat source). The same house will only require 25-30 BTUs per square foot if using a radiant floor system (except under-subfloor applications, which tend to be in the 30-40 BTU range). Additionally, many people find that they can set their thermostats several degrees cooler with a radiant heat system while maintaining the same level of comfort.
