Hello to everyone... Could use some help with my system. Just got my outdoor boiler going (all is well) and noticed i have no circulation to my indoor system. Let me explain my system. I have a oil fired furnace with radiators in the house. I installed a outdoor wood boiler with 2 zones. 1 goes to garage with a 24-7 circulator. It is doing fine. 2nd goes to house. Doing fine. The zone to the house has a hot plate exchanger in the house. Out of the hot plate to the house furnace is a circulator. Doing as it should. The problem is the house circulator which is the preexisting system does not circulate because the house thermostat is not calling for heat. I don't want to rewire it to run 24-7 like the other 3. It will cook us out. How do i get the house circulator to turn on and off with the heat in the house??? Thank you for all who look and help us.
