With only thought for your plan. A mate of mine over in NI as a RE nod had spray foam insulation done on his bungalow loft. He went to sell the house, sold it then all stop as mortgage lender wouldn't loan on the home due to the spray foam. He had the roof removed, insulation ripped out, inspected and sale went ahead. It cost him a fair skate of cash and a lot of stress.richbee wrote: ↑Mon Oct 30, 2023 5:25 pmNot booked yet - I'm hoping to get someone round next week to look at cavity insulating the 80s part of the house before the survey - I think it would be better to have the insulation in place, rather than size the HP based on no insulation and then alter the way everything is calculated to work - maybe....Joeboy wrote: ↑Mon Oct 30, 2023 1:26 pmI wouldn't think they would, more likely a tickbox scenario. I find the idea of the HP fascinating. I might have a crack at working out my own place in Scotland for kW req's. Is there a generic calculator to use?richbee wrote: ↑Mon Oct 30, 2023 1:19 pm
I don't know, but I guess not - the quote just says "Our Surveyor will perform a detailed assessment of your home that allows us to prepare your final system design"
It is a good idea - we've done some work on leaks, especially in the 80's lounge with suspended floor, an open fireplace & non-insulated cavities
I also bought another 3 rolls of the 1.5mm insulation strip we used at daughterlys in Edinburgh. The leak sealing makes such a difference as its 24/7 switch off. I'll be going back round our place next week.
Are you booked for a surveyor?
In terms of the calculation, I was given the MCS excel sheet from 2015 by my neighbour. You are very welcome to a copy of it if you like. It's not the most intuitive sheet in the world, but sure you could work it out
I'm like Pavlov's dogs now when I hear about retro in wall insulation although I know there are more types than my mate had fitted. Worth mentioning I think?
