MITSUBISHI ZUBADAN PERFORMANCE

[dan sw fl]

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 5°F 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.
