While it was done as a new house was being built in my last house i poured a concrete floor on top of a wood framed floor system and could have put radiant heat in that as well. All the necessary components of a well engineered and efficient hydronic radiant floor system are explained in a straight forward and non technical manner. The graph in fig.

The first part contains a general overview of radiant heat and it s various applications. 2 shows this effect for a heat emitter having a design gt of 20 f.

Two pipe systems are the best choice for use with low temperature heat sources such as heat pumps or condensing boilers.

The heat output from most hydronic emitters be they baseboard radiant floor circuits or air handlers doesn t vary in proportion to the flow rate passing through them. Typically 10 of design flow rate yields about 50 of design heat output.
