I was kind of hoping as I know my heating kwh pretty accurately and floor/ cubic area of the house, that would give me heat loss calculations and size needed if the correct maths are applied. 3000sq ft and 45,000 kwh pa (old house solid brick walls) . The current flow temp in is 50c which I think is ok for a heat pump. So I’m thinking if with those numbers it’s all good isn’t that enough real world info to get the sizing correct?

Hi, I’m wondering how to calculate the size of a ashp. I know how many kwh of heat a year I use including hot water. I know the sq ft of my house etc. I’ve found calculators that start from zero, asking about walls, windows, insulation etc. as I know how many kwh of heat I use I would think it’s more accurate to go from there. I’m on a shared biomass at the moment, incoming water temp is 50c, it proving to be unreliable when you need it the most. So thinking about a ashp in the future when the biomass smokes it last polluting pellet.
