The Queensferry Crossing was pretty well handled. Scottish government rather than UK one though.

Just stumbled upon this quote from Antonio Gutierrez: "Today, governments around the globe spend nine times more to make fossil fuels cheaper than they do on making clean energy more affordable for consumers." The idea that switching from fossil to renewables will saddle future generations with higher costs is just not true.

I question the whole 'only well insulated homes can use heat pumps' argument. My house is very, very far from well insulated, nor is it in any sense airtight. And it's working very well with a heat pump. I can see why flow temperature and delta T has an impact, with a wet system, but that will hurt a gas or oil system too. And it's irrelevant to an A2A system.

Yes, pretty happy. For a house that's intermittently occupied, and usually empty during the day, the instant response of the heat pump is great. I don't know how my £4200 compares to installing a complete new wet system with boiler, rads, oil tank, etc. I suspect that oil would have cost more.

I agree, but I presume that the focus on replacing gas boilers is because they are far more common than direct electric heating. Does anybody have numbers on this? FWIW, last year I installed A2A to replace my storage heaters. Didn't go looking for any sort of grant, in my experience grant schemes just tie you up in their requirements. I spent £4200 for a 10kw system ducted to five outlets. I did a good amount of the work myself, but had the supplier of the unit do the refrigerant lines. It would have been nice to not have had to pay for that myself but I didn't think I qualified for any sort of help.

Are SMRs completely site agnostic? Nuclear power stations generally need to be built near water, for cooling. If that still applies to SMR I'm not sure that they'll be as helpful as people make out

France, acknowledged as one of the leading nuclear powers, has just commissioned its first new plant in 25yrs. It came in about four times over budget and timescale. And these are the guys that are so good at nuclear that the the UK is getting them to build new plants for us. I'm not against nuclear, but the cost and time just doesn't seem competitive at all.

Our cottage has a different type of license to our house, and doesn't need an EPC. If this project goes ahead we'd be prefer to offer the caravan on long term rental though. I'm just not sure if we're actually allowed. There's a dire shortage of affordable rental accommodation here and plenty of people would jump at the chance to have even a static caravan to stay in if the price was right. It would feel like I was being part of the solution rather than part of the problem...

Just waiting to check something. If I'm part way through building a house and end up with a serviced plot with a static caravan on it, can I offer that on long term rental? Or would it fail to meet minimum standards like EPC rating? I presume I could use it for short term holiday letting, but it would be very unlikely to be attractive in that market. I presume there would also be some planning considerations?

Hard to tell, it's in Russian 🤔

I think it's hard to persuade the general public that burning wood is bad, in the same way that it's hard to convince people that eating bacon is bad. If humans have been doing something forever, surely it can't be that bad? Unlike those newfangled heat pumps and EVs which are clearly not to be trusted.

Hard to tell from the pictures but it could be something like sarking boards with 20mm chips. You'd want a membrane underneath to prevent weeds from growing through. And ideally you'd be laying the whole lot over a good firm surface, like type 1. You can bed the boards in to type 1, packed down in little trenches.

How is V2G fundamentally different to home batteries?

My MVHR grilles are in the soffits, seems to work well but I can't remember where I got the parts from. Likely the same place as the ducting.
