I have a Hardy H4 outdoor boiler, we all know that it is not the most efficient design but I have a buddy who has a Shaver and that thing isn't very efficient either! Well he has a water to water exchanger and I have a water to air exchanger. This time of year he can go for 36 hours easily between loadings(doesn't load it up very much either). I can usually not do more than about 24 hours if I fill my Hardy up. My thought is that he isn't losing the heat in the heat exchanger like I am, we both run the pumps 24/7. My Hardy is also been spray foamed so I know that I am losing less heat at the boiler itself most likely than he is with just regular insulation. So my question is what are my options to keep from losing alot of heat at the HX? I have thought about only running the pump when calling for heat(worried about possibly pipe freezing in the winter, dont know if that is a legitimate worry though) also thought about a bypass valve inside that diverts the water around the hx when the thermostat isn't calling for heat. What is your experience with losing heat at the water to air hx? Also what are your ideas?
