Mitsubishi system.

It's hard to state precisely how much our monthly electric bills rose due just to the heat pumps (primarily since we also have two dock ice-eaters running during the winter months as well), but I would estimate the two Mini-Split units increased our monthly electric bill somewhere between $125 - $150 during January and February, and slightly less than that in March.

We do have several smaller areas of our home that continue to require heat from our oil-fired boiler, but this past winter we used about 60% less heating oil than we did the previous winter (which was not nearly as cold or long). So the Mitsubishi units definitely saved us quite a bit of money compared to when we heated solely with oil.

All in all, we are completely satisfied with the Mitsubishi heat pumps.

I have had almost zero oil usage all winter from my prior system. Mitsubishi's performed flawlessly. I set my oil system to 50 and the Mitsubishi's to 60. Only on a very few very cold nights below zero did I see my oil system run. The following data might be useful.....

Below is the daily KWH consumption...this year vs. last.
Nov 5, 2012 6.933 Nov 5, 2013 8.286
Dec 5, 2012 3.364 Dec 9, 2013 33.118
Jan 5, 2013 3.567 Jan 9, 2014 53.968
Feb 5, 2013 4.333 Feb 10, 2014 49.219
Mar 5, 2013 3.750 Mar 10, 2014 51.036
Apr 5, 2013 3.452 Apr 8, 2014 47.034

Electricity cost increases......based on daily KWH demand & days n billing cycle
Nov. '13 $5.05 (low...system installed Oct. 30)
Dec. '13 $134.80
Jan. '14 $208.19
Feb. "14 $191.39
Mar. '14 $176.42
Apr. '14 $168.42
Total = $884.27 cost increase for electricity. If I divide this by the average cost of oil of about $3.79/gallon, I get 233 gallons of oil equivalent for the increased cost of electricity. Last year, I bought 328 gallons of oil during the same period for a WARMER winter. So I guesstimate my savings are in a range of about 25-30% less EQUIVALENT oil usage.....not bad in a very cold winter. My house is over 2000 sq. ft with excellent insulation, great windows, and a fairly new three pass heating system (8 years old and it sipped oil). Saving about 100 gallons of oil per season isn't bad, but the payback does take a while. Remember, my prior system was very efficient. But the benefits are hard to refute. Our system was installed for the AC benefits and the heat pump benefits were a lucky strike extra. Top notch system installed by top notch team from Home Energy.

I think you will find that all the systems like Panasonic, Samsung, Mitsubishi's and all the many other brands perform the exact same. I know my Panasonic works just as good as everyone here is saying about the Mitsubishi. I think that the inverter systems work great. I have 2 units one upstairs and one down that produce 24K BTU each enough to do both floors and boy do they keep the humidity down during the muggy season.

we could use one in our current house.. had one in my old house years ago, a/c only, no heat pump. loved it during the summer. i want to get some for our current house but can't cough up the $ out of pocket, and apparenly home energy products doesn't offer financing anymore. bummer..

If anyone in MA is interested in mini-splits/heat pumps there is a rebate program that will be available this summer through August 31, 2014 or when funding runs out, whichever comes first. Rebates of up to $6250 are available for the air source heat pumps (ductless mini-splits) or up to $10,000 for ground source heat pumps. Mitsubishi is one of 3 participating dealers for the air source heat pump program. http://www.masscec.com/programs/comm...ng-and-cooling

We just had 5 (yup 5) of the Mr. Slim Hyper Heat Pump units installed at the Lake. One vendor recommended a single condenser with 5 zones, but we went with Home Energy Products' recommendation for individual condenser/inside pairs. Efficiency is off the charts for these (SEER of 26!) and they will heat at 100% capacity all the way down to 5 degrees F, then at 70% down to -13F.

The multi-zone unit was far less efficient, and we also qualified for 5 of the $500 NH Saves rebates! The systems were installed very professionally, and the HEP crew worked with me to find the most unobtrusive places to run the lines up the house and site the condensers.

I couldn't be happier. HEP's price was far cheaper (read THOUSANDS) than the others, and their system even included remote thermostats and the internet gateways so I can control them from my phone. (Did I mention an additional $200 rebate for the internet thermostats?)

We should be saving big bucks from here. I wholeheartedly recommend you talk to Josh and Steve at Home Energy Products in Belmont if you are interested in these ultra-efficient units!

Home Energy just installed two units for us. The three man crew did a fantastic job installing them. Couldn't ask for more pleasant people to be working in our home. The place is cleaner now then when they arrived. Very impressed.

Just received our electric bill. I'm estimating that it will cost just under $20 a month to run two heat pumps that keep 1600 sq ft very cool and comfortable. Just an FYI update.

Yup, that sounds about in the ballpark of what I figured...

Like hotcakes in this heat!

Hope this link works. (Scroll to the bottom of the page for graph of funds remaining)

We just got our PSNH rebates last week (about a month wait) and it looks like the funds are almost depleted! Act fast!

Stay cool..
