Perpetual Circulation? - Corey Snow

corey

Would the ideal radiant system design have the circulators running continuously?
What are the real world constraints that might make this design goal difficult, impractical, or perhaps undesirable?
Thoughts and opinions appreciated...

Constant circulation

is perhaps the best method for heat transfer. You can read about it from the German fellow who brought it to the USA. His name is Joe Friedrich and he founded Stadler. Here's a link to the articles he wrote which describe the methods.

Constant Circulation

We set up as many systems as we can using this method. It is a system approach to radiant heat rather then banging the pumps on and off with t-stats. Outdoor reset, modulating boiler water temp, constant circulation is the European way of setting these systems up. Why mess with the best?

no article on constant circ on that link that i could see. i can surely see the sense of constant circ, but... it would seem that we have to hope/assume that our o.d. reset curve is right on the money, no ifs an or buts, or the place gets over or under heated... and, we had better be perfectly balanced (which is always nice) or we'll be too hot here and not enough over there?
