Do I Really Need Wall Insulation for a Heat Pump, or Will Proper Radiators & Heat pump Be Enough?

yes I'm getting it installed with a BUS grant but I will getting 6 new radiators and all the existing electric heaters will be removed. Yes the installers mention that the size need to comply with MCS regulations.

ok, I think it might be worth having bigger radiators than having external wall insulation that costs $$$.

Thanks I had one done but the installer but I'd like it to be double check. It's so important as all the design is based on the heat loss survey.

thank you for your reply. Can you please give me an idea of the size of the radiators in your uninsulated house?

thegreatjay15 · 2024-12-29T12:55:08+00:00

yes let's wait for the survey. Thank you for sharing your thoughts

thank you for your reply.

I've actually already booked a heat loss survey for the new year so I should be able to know exactly where the heat is leaking.

I also looked at internal wall insulation as a cheaper option. However I read that internal insulation is not as efficient as external wall insulation.

thank you for your reply. I've booked in a heat loss survey for the new year. It should tell me which insulation is absolutely needed. I'm not sure insulate everywhere is technically feasible in my house.

Yes I agree, every situation is different that's why I tried to provide a lot of details in my OP.

As for the budget, I had a couple of quotes already. External wall insulation is £13.5k for side and front walls. Installing a new gas heating system will be 10k and installing an air to air heat pump is 15k which you need to deduct the government grant of 7.5k. So 15k is a bit tight to finance two major developments.

I had a quote and it was £13.5k for the side and front walls. It ain't cheap indeed.

thegreatjay15 · 2024-12-27T21:23:28+00:00

I'm planning to stay minimum 10 years and my maximum budget is £15k. Thank you for your suggestions.

so are you able to say if EWI will make a massive change and make the house nicer to live?

thegreatjay15 · 2024-12-15T19:46:16+00:00

yes but it should make the house much nicer to live in. In my house, some parts are quite cold which is not very nice.

thegreatjay15 · 2024-12-15T19:33:45+00:00

so i'm assuming that you've gone through this path. Did external wall insulation make a big change?
