I never said it was the best but that it is an alternative. We have had people very happy with their systems on wells and I have heard many people hate it. It is not the ideal setup by all means.
In my opinion gas is the way to go. You're pissing money away with electric. It can be done fairly inexpensive. Not as much for you because you have an all electric setup. Many people out here have propane so it is a matter of plumbing some black iron and installing a change over kit into the gas valve of their existing furnace.
In the past two weeks we have converted three houses over to gas from propane. Minus the tankless water heater we installed at the last one, they were relatively inexpensive jobs.
As far as heat pumps go, they can be great setups and they can be junk. most of the time it is all dependant on the systems used and how they are configured. We use exclusively Rheem units and have never had a customer complain about their system after we were finished with it.
