Heatloss survey and Quote advice.
Appreciate some valuable input from the community on the quotes we have obtained.
Heetgeek came with lowest heatloss which was somewhat surprising whereas octopus seem to be overestimating a bit.
I have pretty much written off the local 1 here because of numbers of rad changes in the proposal.
I've done some basic calculations and to me it looks like the extra £2k initial cost from local 2 for slightly better scop isn't worth it in the long term as it would only make bills slightly cheaper (~£125 per year). Is Midea comparable to vaillant or daikin?
I am slightly hesitant of heatgeek because in the proposal they won't confirm flow temp but do guarantee 360% efficiency. Since we are leaning towards the tank in loft both octopus and heatgeek are almost same price.
We also talked to aira and EDF but both do remote quotes only initially and their survey are nonrefundable so not going ahead with them.
Any advices
