Re: Dont do that electric heating stuff... (none / 0)

Peak COP and year average COP is quite different. You'll never get the higher COP when producing hot tap water in the summer. Also a some brands don't include the power consumed by the circulation pumps when calculating COP :(

I've never heard someone reporting a year average COP of more than 4. Still, when already at 3.5 or so, higher COPs mater less and less. The difference in savings from 2 to 3 is huge, from 4 to 5 is miniscule in comparisation.

Re: Dont do that electric heating stuff... (none / 0)

It's true COP doesn't matter on the power savings side, but it helps in that you can heat a bigger space with a pump of a given size (you save upfront cash on the collector, you save room in you basement, you need less of complementary heating, things like that... and also, I like the best technology, better have it in heat pumps than in sport cars !)
