Hi all, I am helping my brother install a boiler and just had a quick question on whether to use one or two pumps. The stove will sit half way in between house and shop and be used to heat both. DI stance to each is 80 feet. The house is older 1500 square feet with forced air, shop is about 30 by 40 and will radiator with fan blowing to heat. Pry keep around 50 degrees when not working in it. Would it be best to have one large pump at stove, pump to house then have return from house hook to the supply for shop, and have return then finally return to stove? Or would it be better to have to properly sized pumps for each run. Also any thoughts on if it would be worth using variable speed pumps. Thank you all very much!
-
Two pumps for sure
-
Agreed, use separate Circs.

Ok thanks guys! Do you think using variable speed pumps that use the delta would be worth installing for both runs. What is your favorite brand for pumps slim?
-
Grundfos and no on the Delta T, the 3 speed manuals are all you really need.

Agreed, use separate Circs.
I also agree, by having seperate loops for each structure, the heat load from one will not directly affect the other (AS MUCH). I also know its better to run radiant load in parellel than series, dues to better control of supply and return temperatures
