Hi,
We currently have a house which is poorly insulated and has an heat output of 11kw (lots of single glazing). After double glazing, the heat loss is 8.9kw.
We are planning to do a bug extension and loft at some point, adding c.150sqm to the existing footprint.
We have been offered a 12kw heatpump. Should we push for a 16kw heatpump instead? To me, it seems like an obvious yes but I wanted to check.
Thanks!
