We just experienced our first winter using two Mitsubishi Mini-Split heat pump units that we had installed last August. The two units perform exceptionally well, and as advertised they produced abundant heat even when the outdoor temps. were in the single digits.
It's hard to state precisely how much our monthly electric bills rose due just to the heat pumps (primarily since we also have two dock ice-eaters running during the winter months as well), but I would estimate the two Mini-Split units increased our monthly electric bill somewhere between $125 - $150 during January and February, and slightly less than that in March.
We do have several smaller areas of our home that continue to require heat from our oil-fired boiler, but this past winter we used about 60% less heating oil than we did the previous winter (which was not nearly as cold or long). So the Mitsubishi units definitely saved us quite a bit of money compared to when we heated solely with oil.
All in all, we are completely satisfied with the Mitsubishi heat pumps.
