We save well over a hundred dollars a month (more in the coldest months) compared to oil, after factoring in the additional electric. We also find them more comfortable than the baseboards that turn on and off, as they keep the temperature much more constant.
The “hyper heat” heat pumps they have out now go down to about 20 or 25 degrees outside at 100% efficiency, and only start to drop from there (to about 75% at 15 below zero).

So, am I correct that you use your mini splits, over oil heat, to about 10 degrees? My installer told me that that the efficiency limit was about average 30 degrees. Interested in your experience.
