Hi all,
We just had a ASHP co come out to measure up or extension and original cottage to quote for an ASHP. By the end of it they have we needed around 8.6, then added a 10% buffer which pushed us above the 9kw LG single fan unit they recommend. The 12kw model they recommend is pretty large and a 2 fan system. It is meant to be attached just to side of cottage and I think it is just 2 big visually to fit in there.
the extension is around 60sqm and the entire cottage will be 110sqm when complete. I've seen several rather large houses not far from here fitted with a 9kw system by the same company so wondering how such a small cottage, in comparison to some of these large, double story houses, requires such a big system.
Can anyone here point me in the direction of some info where I can get myself up to speed with it all please. The ASHP will be supplying UFH and Hot water and the calcs allowed for a 300l water tank.
Thanks in advance.
