Hi, no I have done that and checked the meter, all is correct, so I dragged my OH around the house last night questioning everything, and I say, what are the fans I hear, what is that? He said, it is the HRV but it is so cheap to run that it shouldn't really affect our bill that much. I say, turn the bloomin thing off, that is what is probably making our bill sky high? Am I correct in saying this, would this be the reason why our bill is so high, only thing I can think of??? Does anyone know how much it costs to run HRV on average weekly? I think we just had the air circulating, no heat was on???
