Cost of operating well
Here's a question I've tried to get answered for a while and haven't found it yet, so please bear with me.
We run a new well pump to supply water for a new open loop ground source heat pump and have been experiencing higher than expected electricity bills. We don't know whether the well pump or the heat pump is the culprit, so we don't know on whom to lean. We're getting the heat pump installer out here Monday or Tuesday to check the installation, and we want to be able to clearly delineate the cost of the well in order to say how much the heat pump is costing to run, or vice versa.
We measured the draw on the well- when it's running it pulls just over 7 amps on each of the two legs. Currently (it's in the teens and twenties here lately) it's running about 2/3 of the time, or 16 hours per day. It runs the entire time that the heat pump runs (as it should.)
We're paying .0899/KWH.
Can anybody help here? FWIW, the static level of the well is 50 feet below the discharge level of the heat pump, if that matters. The well pump is a 3/4 HP Goulds single phase. Wiring is brand new too, inspected and everything!
Thanks VERY much for any thoughts.
