Persistent little buggers aren't they. I must get at least 20 applications from fake email generator sites a day. If any potential spammers are reading this can I suggest you go feck yourselves. Politely of course
Give me the sizes, including height, a few pics and wall construction. Do you have 3 phase (reliably all three phases)?
its at the meter (3phase) but not wired in about 50ft 70ft maybe more brick wall, double apex maybe 30ft at the apex
Would it be fair to say it is not well insulated? Does it have cavity wall insulation and how well insulated is the roof?
£30-40k, so chp would be viable. But I'd spend £10k on insulation then less on your heating solution.
