It runs 24/7 just during the heating season and does my hot water in the house as well. Building is stuffed to the ceiling this year with ash! Have a generator ready and have had to use it once. I just flip the breaker off and made a double male plug. Plug it in an outlet and keeps everything going fine as it is all on the one circuit.Kevin, do you run your 24/7 365? Do you have to have a generator backup for the pump if there is a power outage?
