Reply to comment by raidflex in Heat Pump Cost by raidflex

I would recommend getting a solar audit / quote done before buying heat pumps if you are looking for maximal savings. It pays to at least know what capacity your roof setup allows for - and it would suck if you put the heat pumps in and then the solar generated is no where near sufficient

Ecoer is an increasingly popular brand, who quoted you? Mitsubishi i another very good brand

If starting with oil heat, would try to size the solar for the heat pumps rather than the other way around. Unless it comes back to <$3/gallon, it makes sense to heat with heat pumps regardless of the solar capacity.

Interesting point! I’m curious how high electricity costs can go before it’s prohibitive / neutral to use heat pumps? I suppose the cost of electricity is likely to rise as oil prices go up (as we’ve seen) so there’s a correlation between the two meaning heat pumps are usually advantageous

I did get a quote for a 20Kw system, so there are no issues there. The house gets a lot of sun and has a large roof for panels. Although this is large, it was based on the previous owners energy use, which was 2000kwH a month. We use about half that so far, so we don't need such a large system. I'm not sure why they were using so much energy.

Energy usage varies considerably on the number of people in the house due to laundry, hot water, cooking

There is actually more people in the house then with the previous owners. Still more then 2x-3x the usage seems awfully excessive. There was months in the middle of winter that was as high as the summer months with central AC running. The water heater uses oil, so that would not account for much electricity.
