    Thumbs up MITSUBISHI ZUBADAN PERFORMANCE

    Is there going to be any market share for a more expensive Cold climate heat pump?

    Has the heat pump performance at close to 0'F actually been proven in real life experiences?

    I guess it will take that special customer with a high electric rate + Cold climate to make this their selection.

    Any thoughts on this product actually getting a noticeable market share in residential heat pumps?

    Are these series currently offered in 60Hz?

    MXZ-3B24NA might be the North America equivalent.
    It's AHRI rated to heat 25k at 47 and 14k at 17, with maximum output of 30,600 at 47 and 18,800 at 17. AFAIK, they don't publish 5F specs for the MXZ like they do for the Hyper Heating models. See page 21 of the brochure for specs.

    I'll be running a Fujitsu 9RLFW soon, I'll try to calculate an approximate heat output and power draw if we see single digit temps in Michigan next month. (Page 13 in Fuji brochure)

    As a consumer, I think there is considerable market opportunity in propane country for an air source unit that can put out substantial BTUs at minimal ambient temps, as long as:

    1. It's significantly cheaper than ground source to install.
    2. It's significantly cheaper than propane to run. That would mean COP of 2 or more at low temps in my case.

    If I were a natural gas customer, the obvious question would be 'What's the cheapest 95% furnace you can install for me?'
    It's hard for any heat pump to compete with NG when the electricity is 12 cents a kWh and your design temp is around zero F.

    I think you're looking for the special customer with low electric rates compared to their cost of combustible gasses. If their cost of electricity is high, they're better off with a furnace.

    For me propane is about 2/3 the cost of electric this year, so my breakeven is at a COP of 1.5. I went for the 'cheapest 95% furnace' when I bought a house without a furnace, and then went for the 'cheapest Fuji/Mitsu/Daikin inverter mini split' when I wanted to try to supplement it with some cheaper BTUs. (the 9RLFW normally sells for slightly more than the Mitsu GE09 and slightly less than the FE09, I would have definitely bought the FE09 if I hadn't snagged the Fuji on a no reserve eBay auction for three digits)

    Sometimes I think I should have just bought a hybrid system with a 13SEER 1.5 ton heat pump piggybacked on my 95% 45k furnace when I put the furnace in last winter. The main advantage to the mini split is I don't have to shut it off in cold weather when the furnace kicks in.
