I would not count on that, cars that were legal on emissions a few years back are now effectively banned. Can't comment on government future timetables, if I could I would write a cheque and get you all the labour and materials you wanted.

@Adsibob You are in London right? Are you not concerned about the legislation changing that will ban woodburners. The currently updated legislation is pointing in that direction already.

I fancied munching on a pop tart the other day, it never happened.

That is for LPG, not natural gas.

How does that compare to what you are currently paying? Too true. The testing method was completely different. The manufactures set there own methodology and it was rejected. Just remember, you cannot fool nature.

Would hardly be a Cornish Breakfast without it. Stop doing Vegan Breakfast would be much more environmentally friendly.

It is Thermal Conductivity Value you need to find. U Value is thickness and area specific. https://en.wikipedia.org/wiki/R-value_(insulation) This may be useful. https://www.engineeringtoolbox.com/heat-loss-transmission-d_748.html

Many all electric flats are in E7. Get a video of the meter and see if it is cycling through different price bands (some meters need buttons pressed).

The price is low enough, but the cost of burning toast is very high. Sets the alarms off and you have to clear out 50 diners. Fitting a better alarm system was a higher price, but much lower cost, so better value.

There is price, cost and value. You can vary them all as much as you like and still burn the toast.

That is a dreadful reason. If medical surgery was as reliable as building, not many of us would be around. When you start the journey that is education, you don't go into say an English lesson and spend 40 minutes doing PE. When you get on a train from London to Penzance, even if things go wrong, you won't end up in Glasgow, and being charged an extra 200 quid. The building trade really needs to up its game and become professional rather than the bodge it and scarper mentality. The customers need to reinforce what is expected as well. If there is a scarcity of Labour and materials, then it is time to reassess the project, even if it is halfway through. People talk about contingency, but they usually just mean cash, it is really about salvaging when it all goes tits up. Used to be called Plan B. If you are having trouble getting quotes, decent prices, that is economic theory telling you something, generally don't bother.

All I need to make 150 meals a day. We only have 2 ovens, neither of them very big. There is so much nonsense spoken about cooking.

GRP boats float for many years, so don't worry.

Hit the bottle and you may be chanting that every week. Wonder if Alice in the Archer's will be joining them.

Not really, they are limited capacity and a lot more expensive than a water cylinder. Heat losses from a cylinder, though higher, are not much of a problem in a large old house. Most old places like this only have 2 months of the year when they are not heated. And that is in Cornwall, no idea where the OP is located, may be NE, or worse.

Just thought I would see what the energy content of LPG was, ~7 kWh/litre. So a 45 kW boiler would burn around 8 litres of fuel (allowing for some efficiency losses, actually 6.43 litres). A quick google and the price seems to be about 45p.litre, so to run a 45 kW boiler for an hour would be £3.6. Get insulating and fix those air leaks.

Can you fit one on top of the other?

I have not permanently fixed in my IH yet, I was thinking of making something similar as an extractor for mine. I want to fit some heat recovery as well, so an extra challenge.

Sensible when talking about thermodynamics. Latent is to do with phase change.

LPG is generally the most expensive, and you can easily get locked into a single supplier. Reducing losses is always the best thing to do.

Have you done a basic heat loss calculation on your place? 100 kW (not kw) is pretty big, but not ridiculous if you need a lot of hot water. Does it heat a cylinder up, what size it that?

Run a hose on it for an hour or two. Though I expect it will fail after the summer, differential expansion, felt, being a type of 'wax' will also act as a release agent.

What do you do if you have 21 windows.

It is relatively easy to put felt onto GRP, never tried the other way around as I know it would cause problems. Have they poured lots of bitumen onto the joint?

What power rating is your current boiler? And do you know how much fuel it used every year? Does it keep the house warm, and enough hot water? A kWh of energy is agnostic to fuel types, just as power is.
