I am starting the second phase of my boiler system. I want to get my shop infloor up and running. My Tarm and 1140 gallons of pressurized storage are in my home with the storage in the basement. My heat loads in the house run off a Grundfos Alpha 15-55 which will also push water to a heat exchanger on the back wall of the house where I have 1-1/4" Thermopex. The Thermopex runs 150' to the shop. In the shop I have 1200 square feet of heated space. The Grade Beam slab has 1.5" high density foam underneath and 1" high density around the perimeter. The walls are also spray foamed and then batted. Ceiling will be blown in fiberglass. I installed 6 loops with a average of 275' of Wirsbo Hepex O2 barrier in the floor. My question is how large of a pump do I need to pump 150' from the house to the shop? I was thinking I would put the mixing valve in the shop instead of the house so I could still add a high temp unit heater if needed. Also what size pump would run the infloor and can the same pump supply the high temp unit heater? I also ran CAT 5 wire in a conduit from the house to the shop for control wiring. The system will be filled with glycol. I am looking forward to any suggestions and imput.
