Higher than expected electricity consumption?
I've had geothermal heating and cooling for a year now (near Ottawa, Ontario). Reviewing the electricity bills for this period shows very high consumption during the winter months. In January, for example, we used over 2,200 kWh. While obviously not all of it is due to heating, the difference to summer months (about 900kWh) cannot be explained by any other change in consumption. My wife and I opted for geothermal under the assumption that it is the most economical and environmentally-friendly heating option, but now I'm not sure about the former (the latter is still plausible in Ontario, as the vast majority of electrical production is clean). Even the summer consumption is not that much better when compared with the A/C unit we had in the previous house.
Is this the norm, or is there perhaps something wrong with this specific unit?
