Yes, but we are a global trading nation, I have no problem with overseas companies investing in the UK. Quick look at Companies House and Vesta Offshore Wind Blades UK is a registered company with a turn over of £85.55m. Here Wish they were in Penzance.

Brent Crude is £48/barrel ($64). About 50% of the energy in a barrel can be converted to heating fuel, so 850 kWh. £10k will buy 208 barrels (today) or about 180,000 kWh.

I did some work for a UK turbine manufacturer in the early 1990s. I think then we were the biggest global manufacturer, though they used the term 'leading' which means very little. They still make turbine parts there, Vesta employ a lot of people. This is currently in Mount's Bay, but think it is just parked up.

Some of that kit will last 20 years. in 2022, the UK used 1,200,000 barrels of oil a day. So we have to get a new barrel every 14 seconds. A barrel of oil is currently a similar price to 400W PV module, that would produce about 500 kWh/year down where I am (I am quite happy to cover Cornwall in PV). A barrel of oil has about 1700 kWh of energy in it, but we cannot extract much more than about 70% of that. So in just over 2 years, a PV module would produce about the same raw energy as a barrel of oil. Then about 18 years for nothing.

Try my secondary glazing idea that I suggested for your main windows a while back.

These people could supply all the kit needed. Any GRP fabricator could do it, but no reason what you could not do it yourself.

Why not coat the PU/PIR sheet with GRP, then fit into place. Works well on boats.

Think this may be a social class issue. Just put room numbers on everything.

Can you soften it with a blow torch. Or put some mix in a barrel and light a fire under it. Pour into hole, put a metal, or even timber, plate over it, then drive over it a few times. Rinse and repeat till level. (Road making materials are, by mass, the world's biggest recycled materials)

So bathed in warming microwaves. Non of us are far from a military base. I used to live and work in High Wycombe, home of HG Air Command. Now I am fairly close to RAF Portreath, and RNAS Culdrose. Would have to cross a 'radiation' zone to get out.

Not on its own, but a few of them on a short circuit scrambling track will sort it out, and you can charge an entrance fee.

Only read your abstract of what you intend to do. Does your incoming mains support this, there will be a drop in flow once all them bends in the pipes and the length of the pipe rums is taken into account. Effectively two different types of heating systems. Not a problem as suck, but needs a bit of careful thought re flow rates, flow temperatures emitter areas and the different heat distribution within a room i.e. where the radiators are located. As I am sure you have read from people that run their HPs efficiently, they are effectively 'on' all the time, so room usage is just a distraction. Treat it as a room that is always at 21°C. (maybe a slight setback at night). Fit as much as you can by all means, the marginal costs difference is minor, and maybe negative. Don't think there will be need for additional wiring, but it does depend on if it is an AC or DC coupled system. Initially get a suitable inverter for your capacity that is acceptable to your DNO i.e. how many amps you can connect per phase. Worry about battery storage when you build the second house, the energy market will have changed (again) by then. You have to fit one, so no point fretting about it. If you put the cabling into conduit, you can fit another cable into it for battery storage (EV charge points are usually in a garage, where batteries may go in the future). Bet that is (expletive deleted)ing noisy, fit quadruple glazing. As an after thought, and replying to this This is why some of us have to do the right thing, we cannot rely on others. It also stops them having to know anything.

I don't understand the 2012 pricing. 2012 was when we held the Olympics. And a good TV series about it.
