Proper use of multi-split heat pump
We recently had a multi-split heat pump system installed in our home in CT (5a). We have one head upstairs, one that feeds the kitchen and living room on the main level, one that feeds a back room on the main level and a mini-split wall unit in the lower level rec room. We were a little bummed to find our energy bills after the first month didn't really improve - our oil bill went down, but our electricity bill went up so much that it canceled out any savings. I am wondering if we are not using our system as efficiently as possible. Since it has four "zones" effectively, we have been running them all at different temperatures. In fact, the rec room wall unit is only turned on when we are down there. I am wondering if this is not the best way to use this system during the winter. The main unit in the kitchen/living room is always set at the warmest temp and never seems to quite reach that (68 degrees). Are we actually wasting energy by making it work too hard while the rest of the units are at a lower temperature (or off)?
