I'm setting up a triangle tube 175 Solo boiler with a Superstor 60 domestic tank.
Triangle Tube calls for domestic to be piped off the primary loop. They also call for a circulator pump on the primary loop, and a differential pressure bypass valve in the middle of the loop($200!). Do you feel it is essential to follow this scheme?
My primary pipe size is 1-1/4 and the (9) heating zones (total btu 100,000)are piped in 3/4 pex. I calculate my head loss to be 30; gpm demand 12. My domestic has a maximum gpm of 7, head loss of 25. The system will be set up with taco sentry zone valves (we were going with 0007 pumps on all zone but have changed course)
I am looking at taco 0010 for domestic and Grundflos ups26-99fc for the primary loop and system circulator.
Any feedback appreciated.
