Mini slip heat pump as primary heat source?

Question

Does anybody know if Maine lenders allow mini splits to be used as primary heat source￼￼￼? I don’t want to have to go back and install another heating system when I want to sell the property.￼The house is currently heated by a single MPI kerosene heater. I am looking to upgrade to a efficient mini split￼ system (efficient down to -30 degrees) ￼so I have AC and heat in multiple areas of the house. ￼

HI @Chris Cogan, there should not be any issues with having mini splits as a heat source. It is becoming quite common in Maine to have for your main source of heat.

I would look at keeping the heater you have there also, unless it is so unsightly you feel it negates the security of having a back up heat source. If you are renting it out you could just have the tenant know that it is part of the heat system as a backup.

@Chris Cogan I have not seen any lenders care when the primary heat source are mini splits.

@Eric James no, there wouldn’t be another back up source because the newer mini split systems are efficient at heating down to -30°F. ￼

I use heat pumps as primary heat source.  In one of my buildings it's the only heat source.

@Dan Weber thank you, I figured as much but I wanted to be sure.

I've been told by HVAC guys that heat pumps don't work when temps get very cold. Does what you're talking about have a back up heating system for cold temps?
