Paul as kezo says i have a large house and I’m based between Glasgow and Edinburgh so have a high gas bill at the moment hence the anticipated move to an ASHP.
My gas usage last year was 16,500 kWh f or heating and hot water. I plan to keep my combi boiler for hot water and as a safety net in case the ASHP turns out to be a bad move.
There are a couple of options to reduce the pump size but I’m not sure it would make a huge difference. I have 200mm of loft insulation that i could easily increase. I have sprayed insulation to my entire downstairs so that’s fine. My windows are all double-glazed but very old. The two main living space windiws are both 2.4m x 1.8m so i could maybe reduce some heat lose by changing the glass units to Argon-filled. I have a mate who owns a glass company so this could be an option.
The house has cavity wall insulation on the existing section and timber frame with 75 mm thick insulation on the extension.
So there’s a couple of things i could do and might yet do but I’d probably be tinkering around the edges.
What size of ASHP do you have Paul and what has been your experience with it?
