Circulator size needed

spacoli

Hi to all. I have a room with around 10,000 btu heat loss with two  equal loops (235 feet) of 1/2 inch pex radiant floor in concrete.



I need a circulator size with a typical supply and return type manifold (home made tees),required ball valves and mixing valve. Any info, thought or opinions appreciated. Thanks

15-58

I would say Grundfos 15-58

Ideally you will push about 2 gpm at a delta t of 10. The nice thing with the 15-58 is you can dial in the speed to get your delta t correct.
