Not neccessary, because the heat pump can also operate with 100% outside air.
I didn`t find the outdoor temperature operation range. Do you know it?

It's a bivalent hybrid boiler-heat pump.
There was a German company showing one at the London HEVAR show last year.
I don't think that there are many sold yet, but it's an interesting idea.

They claim that just over 600 watts is converted to 2.5 Kw, that is a resonable COP calculation.
Their only claiming it, at about 4 to 1 which by some heat pump manufacturers is downright ineffiecient :D
