Hyper Heat Pump in Cold Climate

user-1142226794 | Posted in General Questions on

I was wondering if anyone has installed/used a: “Cooper & Hunter Hyper Heat 18,000 BTU Ductless Mini-Split -22F Heat Pump” The negative 22 degree ambient caught my attention! I will be installing two 12 – 18,000 btu independent systems for this winter and am looking for suggestions for the cold weather (Vermont winters, Zone 6). Thanks for any links, resources, and info.

    All these units are made by Gree or Midea, two of the biggest hvac manufacturers in the world. There are many different product ranges for each with very different performance, lot of times the offbrand units are from their budget lineup.

    Most will be rated down to -22F but that doesn't mean it will provide much heat. You'll have to do a bit of digging to figure out which model will work for you this a good resource for searching for this information:!/product_list/

    Anything that maintains the nameplate or above capacity at 5F is a good cold climate unit.

      Akos, thanks for the reply.

      I have been looking through the NEEP figures, thanks for the link. So when I compare different units I am putting location and BTU into the capacity calculator for my area. In the picture below am viewing the 18,000 BTU Mr. Cool system. The owners manual says the unit will operate to -13F so I changed the capacity rating. I am getting a Percent Annual Heating Load of 89.5% Meaning that this system will only provide 89.5% of the heat I need in this space. Is that the correct way to read this graph/data?

      Thanks for the information.
