I just received my electric bill from the first month of using my OWB and it's double of what it usually is. It probably doesn't help by having a heater in the hen house either, but do these pumps and blowers suck that much energy? I have two Wilo Star 30's pumping to the house and to the barn. In the barn is a single zone Taco 007. The Wilo Star's pump continuous and the fan on the boiler only kicks in when it needs to. I am sucking down the wood, twice as fast as I thought I would, but the consumption of the electricity is killer....You think it's the heat in the hen house or the OWB system? Looking for clues.
