Would love to see a spec sheet or results from standard rating tests. They don't say under what boundary conditions (outdoor air temperature, hot water temperature) they hit COP 7. Most heat pumps can hit COP 7 under mild conditions, which is why SEER/HSPF ratings measure COP under many conditions.

..down to sub-zero (F) temperatures. The important things to check about the heat pump are its Heating Season Performance Factor (HSPF above 8.5 or so is good; 10+ is great) and its heating capacity at a cold temperature such as 5 F, which should roughly match the building's peak heating demand.

On the other hand, I don't understand how the NEEP ratings, which I usually more or less trust, are accurate for the 11 HSPF Carrier VNA1. How do you get an 11 HSPF, which is a SCOP of 3.22, when the COP is never above 3.22?

High HSPF inverter heat pumps capable of heating a typical SFH are expensive as fuck. There is a reason builders install trash. My BOSCH Bova (deez nuts) IDS w new duct work was around $15K all in. Not bad but way more than the average person will want to pay. It's also not that much cheaper to run

In the U.S. we use SEER and HSPF to describe their COP in different modes. Anyways, it is the efficiency of your heat pump, along with the quality of both it and the installation, that will determine the long-term cost of ownership.

HSPF to SCOP conversions are pretty simple, at least in Climate Zone 4. HSPF / 3.412 = SCOP. It's an approximate rating, but the "Heat Pumps for All?" authors decided to make up their own math, despite acknowledging that previous work found a SCOP of 3 was about the best achievable performance.

You mean high efficiency inverter heat pumps. There are some absolute garbage tier heat pumps and installs out there. I’ve suffered through plenty. The good ones are $$$$. I love my 22 seer/high hspf bosch. It’s also way out of the price range of many homeowners.

Ah, we were quoted for 4 tons I believe, I wonder if oversizing is a separate problem. I can’t imagine my California house needs more heat than your folks’ place… what SEER/HSPF did they get? Out here you can’t get any rebate unless it’s above SEER 17/HSPF 9.4
