Dear all,

What is the best way to model underfloor heating? I hot water boiler that supplies hot water through underfloor pipes. Please advise if I am doing the correct thing below:

I chose is a hot water condensing boiler with a hot water loop. The hot water loops asks for process loads and process flow. What shall I input in them? Also, shall I choose primary or secondary loop subtype and sizing option?

Moreover, will this appear as in the space heating row in the simulation output?

Many thanks,

Omar Katanani
