There is an available programmable thermostat (), but it is intended to be installed with the heat pumps, not after the fact.īuy Wireless Remote Controller and Reciever Kit - MHK1 - Thermostat for Mr. The best you can do with the included remote controller is set them to turn on and off once each during a given 24 hour period, and you have to manually set this up every day to use them that way. In New York’s Hudson Valley where I live, A/C is only useful for about 1 month a year, but it’s sure nice to have during that hot and sticky month! In any case, I’m happy with the mini splits except for one thing: they have very limited programability, something I did not realize before I had them installed.
The mini-splits will have an estimated payback of about 13 years, which is not great, but both they and the geothermal system have the added advantage of giving me efficient air conditioning in a home that did not previously have it. The geothermal system would have done better, but even if it cut my heating bill by an impossible 100%, it would have taken 25 years to pay back my investment. After using the air source heat pumps for two months, I expect these mini splits will approximately halve that. The geothermal systems I was quoted would have cost $50,000 to $60,000 (minus a $500 rebate from my utility), while the mini-splits cost $15,500 (minus a $2000 rebate.) Because I’m also doing extensive insulation and air sealing, my heating bill is only about $2000 a year, even using oil at over $4 a gallon. The mini splits have the advantage that the refrigerant lines can run up the outside of the house, making them much easier to retrofit.
#Mitsubishi programmable thermostat series#
Slim mini-split heat pumps installed (three MUZ/MSZFE09NA 9000 BTU units, and one MUZ/MSZ12NA 12,000 BTU unit.) If price had been no object, I probably would have gone for Waterfurnace’s (TSX:WFI/OTC:WFIFF), but my home’s existing heating is an oil boiler and radiators, and the Series 7 would require installing air ducts throughout the house.

As part of an ongoing energy upgrade of my 1930 home, I had four Mitsubishi Mr.
