Heating System
I am buying a building which has no heat but only electric heaters in each unit which are not efficient at all. I am thinking of installing instead a Mitsubishi multi-room ductless air conditioning heat pumps – Cooling and heating for each unit. I would like to get inputs of anybody who has tried this…

I would like to get inputs of anybody who has tried this in the past.
I’m interested to see what you’ve decided as we are coming to this same decision. Have you heard decent things about the heat pumps for our climate? Any quotes on monthly heating costs?

Who is your rep? Our rep is Iceberg Mechanical in Brooklyn.
He told me that if you take the Mitsubishi Hyper-Heating INVERTER H2i
P-Series as primary it works fine under all cold weathers.
I’ve read the same: that heat pumps are intended for mild climates and that as you get into sub-freezing climates not only does its efficiency drop as a heat source, you also run into problems with the outside exchanger icing up and requiring a shut-down and de-icing.
We are in the process of renovating our house and will be using these units as our primary source of heat. Our hvac contractor is not worried about it. I’ve spoken with a few people who have similar and are fine.
dumb idea…if you want to design a realistic system, email me at errol832000@yahoo.com
Yes to the above, they lose the ability to make heat when it drops below 45. Even above 50, be advised that the heat they make is technically heat, in that a therm gauge will prove that the air exiting the unit is 15 degrees warmer than the air exiting. But it does not feel warm when you judge it bythe temp coming off a radiator.
Nevertheless, it is nice in Sept/October, when it 1st gets chilly, and you get heat quite econimcally then.
As mentioned in a previous post heat pump systems do not work well in colder climates in the north east, and work better in areas like the mid Atlantic. You would be much better off installing a hot water baseboard or forced air system (if you can fit the duct work).
AFAIK the heat pumps in these units only supply heat when the outside temperature is fairly high (50 degrees,or so). When outdoor temperatures are lower they use electric resistance heat, which wouldn’t be any more efficient than what you use now.
Our Mitsubishi rep said these were not powerful enough for weather below 35 or 40 degrees.
