I'm sure you will. B-)

In fact it's getting real world figures that is important rather than
back of a fag packet guesstimations.

I wanted to put heat meters on each source here, log the data and
bung graphs on the web. The thermal solar panels have one in the
controller but I'd have to fit something for the wood burner, oil
boiler and CH zones, to see where (most of) the heat is going. Snag
is heat meters are expensive at a few hundred quid each and there is
some doubt about having one in the gravity loop of the wood burner,
it might stop the circulation. The oil and CH zones are pumped so
they wouldn't be a problem. So this isn't happening but may at some
future date.
