Hi all, had a question about using both of these in series, which is how I have them connected. Since the price of pellets has increased and oil is down from last winter, would it be cost effective to use both at the same time?? what would the temp settings be if i wanted to mainly rely on my pellet boiler?? i have a triple action aquastat on my oil boiler. Anyone have experience with this?? Thanks for any help. I am thinking of using this when the weather gets coldest for me in Jan and Feb.
