Building 30m2 garden office / gym Slab is down with no insulation yet, Ive got maximum 100mm for insulation and flooring etc. Ive no idea about heat pumps and if I get one maybe offset cost if it might do heating for house too. About 85m2 No idea what parts are or what to buy. OK with general plumbing etc. And budget limited to about 2k the new build will need to be kept warm 24/7. Last resort is to get a small boiler and ufh etc New build will have roof, walls and floor insulated. About 12m2 double glazing. 2/3 is gym and 1/3 office space. I am also disabled so looking to not add much extra work.. If I had more cash would have gone for ground source heat pump etc.
