How often should the pump circulate? I set it to come on at @190F and it goes off @150. There is no way to set the off temp. I you move the on temp up it also moves the off. I know it is not good for a pump to cut on and off. I am assuming that as the water is moving through the pipes the heat is being removed and as it returns it is below the off temp. Should I set it low enough to run constantly? Seems this would make heating the water take forever. How should it work. In my area nobody know about boilers. I paid a guy 130 dollars to come stare at it with me for @45 minutes in my basement.
