Aerogel? Been looking at this for the walls - stone - need to breath etc. Went outside for a little cry when I saw the price.... ?

Thanks for the pointers guys. Sounds like it's not a great option. I have an Eddi device on the horizon for the solar PV. Only trouble is having chartered the gas usage on the hot water alone (through the summer), it's never going to pay for itself - even if it provided the entire hot water. The system we put in has a loop for solar hot water, so I'm thinking I'll go down that route instead. For the under-floor sounds like a none starter. A wet system would need the floor digging out as there isn't the clearance on top. And to do the insulation properly would generate approx 40T of soil, with the obvious cost of the insulation / fitting on top. The property is 120 years old, so really doesn't lend itself to being onzone friendly - hence me exploring ways to generate more heat (which I can then lose) for free....

Had a feeling that may be the case. No planning as yet. TBH I've been all around the houses and all the way up to £30K and back down. We have a good size solar PV system, and I started working on the principle that if it's not sunny it tends to be windy! Then if I put a battery in, the solar will cover most of the energy pull - until we start using it for heating.....then we need wind, but do we need £30K or just extra for heating the one space... and around in circles I go again ?

Hi, I'm about to renovate the kitchen in our old house, and was considering under floor heating. The current heating system is not compatible with under floor, so electric is looking like the answer. However, given the current situation with energy prices, I was wondering if I could buy a home wind turbine and use it directly with the underfloor heating. i.e. everything the turbine generates goes straight to the heating matts. Of course, the max rating of the turbine would need to be under the max combined rating of the mats so they don't fry, and for the most part they won't be operating at full whack. They will be complimenting gas boiler / radiators, so it would be a case of "any heat is a bonus". Anyone done this or seen it done? Any advice on turbines? some on ebay claim to be 9000w, but look the same size as ones with a fraction of the output? Advice / comments gratefully received...
