About Radiant Heat
In a resting position the human body will produce about 400 Btu's/hour. This is about 300 Btu's more than we need to survive.
In order to "feel" comfortable, we need to shed these extra Btu's. A heating system is a mechanism is which we control the rate excess heat is lost.
The slower we lose heat, the warmer we feel.
In order to heat a space, something within that space has to be warmer than the desired space temperature (hot to cold).
In a forced air environment, the air coming from the duct is between 120° and 140°, assuming a 72° desired room temperature.
In a radiant floor system the floor temperature is between 72° and 85°, assuming a desired 68° room temperature.
