Why can't I find a heat pump with a good SEER rating? The USA has a
law stating 13 minimum. Yet here in the UK, I looked at Panasonic
and
they're all 7 to 11!

Which suggests that the seasonal weighting parameters used in the US ,
Europe and possibly UK are all different which will give very
different
figures.

So if he compared the EERs, he'd get a fair comparison between those
sold in the US and UK?

This is the more important question.

Does the US have a regulation on minimum EER?

Presumably you mean the UK. No they don't.

No, I meant the US. He says there's a minimum SEER, but I'm curious if
there's a minimum EER.

One is proportional to the other. SEER assumes a set temperature.

BTW, a good chance you can't find the exact same model number in the US
vs. UK, even if they were the very same, but since the cps is different,
they're probably not the very same.

What is cps?

cycles per second, mains frequency, Hz, They have 60 you and I have 50
