Central, IA | That might work. Can you tell if the boiler is modulating down to the lowest setting when it is cycling?
Is the outdoor reset hooked up and is the temp curve set appropriately?
I have 3 speed grundfos circulators in my shop. I ended up with them both on high because the boiler that replaced the 2 water heater system from the 80's wasn't big enough.
Is it all on one zone? I heat my garage and porch with a heat exchanger on my water heater. I have a variable speed circulator that adjusts for zones turning off. | |
