Viessmann vitodens wb2b / 35 pumping
I am installing a Vitodens 200 WB2B 35KW for Hot Water & Heat (Teledyne Larrs indirect) taking off the supply side (bypassing the LLH) and a LLH supplying 3) 3/4" zone valves (honeywell) baseboard 1) 1" zone valve (honeywell) baseboard and a Zone (constant circulation) the coldest room with a vitrotrol 300 (thermostat) with no zone valve. The zones are all different lengths. I will run the system with a outdoor reset and the Vitrotrol 300 will give me the option to get that room a bit warmer when needed. I would like to install 3 Taco Bumblebee circulators. The home is in Stowe Vt. -30 degrees design. and will normally be 50-55 degrees unoccupied. When occupied we like it 70 degrees and have a wood stove and pellet stove hence the vitrotrol 300. Any ideas about pumping, pumps (maybe Delta P) Delta T setpoints or anything else I might find interesting. Thanks for your help in advance. Kevin G.
