Conversion from Electric heat to oil ?

The Real BigGuy · 04-05-2018, 12:35 PM

I have 3 Mitsubishi head units running off 2 compressor units. They are not the Hyperheat units but, the heat the house comfortably down to about 15+/- (hyperheat units are supposed to provide heat to -5 or so) degrees. I went from a tank of oil every +/- 3weeks to 3 fills this year. I was real surprised when I found that my electric bill didn’t jump like I expected. My son-in-law installs Mitsubishi’s and his company only sells the hyperheat units now although, they still recommend that you do not use them as your primary heat source during the winter

Our Mass house has 7 Mitsubishis spread over 3000 sq ft. Except for an occaisionally used gas fireplace insert, they are our only source of heat, and they were champs this past winter, even with extended periods of sub zero temps.

Nice to hear lots of happy campers. Note, the M series FH model is the newest and most efficient. Some dealers will try to sell their older FE models, which are less efficient.

I have installed 15 of these units. I only use singe units. I find that three singles cost about the same as one three head unit and are more reliable. I am an experienced plumber and electrician, so I do the rough-in, run the gas lines, mount the condenser/evaporator and then have a LICENSED HVAC person connect the tubing - purge - evacuate - purge - evacuate and maybe yet again. This is the most important part. If any moisture remains in the lines, you WILL have problems. A licensed HVAC person must do the final install or no warranty. Find an HVAC tech who does these all day, every day and really knows them. Anybody know about rebates?

Put mini splits in with solar panels ... not paying for heat is so amazing!
