You loose far more with an intermediate battery between the generator and

Perhaps I didn't make it clear enough that I was talking about a system
that provided electricity not just heat.


I think News was addressing your comment that it turns itself off as it
has nowhere to put the power.
Heating a thermal store of 1m^3 takes about 1Kwh per C.
Going from 40C (UFH temps) to 95C would absorb some 4 days continuous
output.
And it's relatively easy to make larger thermal stores.
