in Radiant Heating
Hello, I am trying to figure out the best setting for my in floor heating in my basement. My outdoor wood boiler supplies my hot water for everything. I would like to just maintain basement at about 68 degrees. I have a 2000 sq foot basement. My pump is a grundfos 15-58 3 speed set on speed 1 and with a simple honeywell mixing valve that is set at approx 2 clicks above 80. What would everyone recommend for pump settings, ect?

    The only proper way to control a slab due to its high mass is with a smart mixing valve or variable speed injections mixing, either of which operate based upon outdoor reset. Using a dumb valve (thermostatic) will result in either under or over heating depending upon where it's set. The water temp has to be varied to meet the actual load. Changing pump speeds or valve temp won't accomplish this - unless you want to attempt it hourly.
