Typically 10 of design flow rate yields about 50 of design heat output.

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.
Radiant floor systems can be considered two pipe systems since each floor circuit is connected in parallel with the other circuits at the manifold stations.
Two pipe systems are the best choice for use with low temperature heat sources such as heat pumps or condensing boilers.
2 shows this effect for a heat emitter having a design gt of 20 f.
The second section gets down to the nitty gritty details of actual radiant floor installations.
This is about installing hydronic radiant floor heating in a slab floor system.
All the necessary components of a well engineered and efficient hydronic radiant floor system are explained in a straight forward and non technical manner.
