Guys/Gals,
I just got my gasser fired up and have a small problem with backflow. My storage is in parallel. When th house calls for heat and the boiler temp is above 125, the house gets heat directly from the boiler. If that temp falls below 125, then the tank will heat the house. The tank charges when there is no call for heat from the house. Heres what is happening... When the house is calling for heat and the boiler temp is above 125, the heat is circulating through the house but it is also flowing back through the tank return pipe from the manafold and still charging the tank even though the tank circulator is not on. If I turn of the tank return valve it works fine so I don't think its an airlock problem. Does anyone know how to prevent this???
