First two are almost right. The wave power isn't. To the best of my knowledge there has been no, large scale, wave power that has been successful, globally. Mate of mine worked in the industry and he left because he got fed up with 'hopeless projects that were going to fail'. To quote an engineer based at WaveHub, 'it is a bit rough out there'.

C is usually used for coulomb, not sure that 3 of them is 1200A. Or have I misunderstood something. 3C.s-1 = 3A

Well it is meant to work like a mirror. So why don't we put acrylic mirrors on our walls and lofts.

Do you know how much energy you currently use, and when you use it? If not, find out.

Second idea. How about creating a new facia that runs the full width, and a bit deeper. Use that to cover the existing gutter, 3 short downpipes going into a larger pipe (that is hidden behind the false facia), then to a popper downpipe at one end.

What power oil burner has been suggested?

Have a hunt around on here for Jeremy Harris's spreadsheet. That is about as good as you need. As for why you should do it, it is because it allows you to change thermal performance of the fabric elements. That can save you thousands.

I was just trying out posting from my Kindle, using Brave. It won't let me post from my old one since the forum software upgrade (downgrade in my case). But works fine on my newer Kindle. So time to root the old one and see what it can really do.

We often get asked on here how much a build should cost. Usually this is based on £/m². Why not base it on a multiple of Architects fees. So when you want to build get an estimate of what an architect will charge, then multiply by 20. Then laugh.

Who told you that?

So hopefully that will discount any serious scaling up. Does seem odd that is has got gradually worse. Check the thermostatic valve.

Have you got this far without thermally modelling your build?

Are you in a hard water area and are you using a water softener?

Relatively small area though. Couple of days work and it will look lovely.

Isn't the key part 'diversity'. So taking scrubland, which has low biodiversity and just planting plenty of different local plants, especially ones that may attract nesting birds increases the diversity. It is the argument that golf courses use when converting farmland to waste of good building land.

Here is my one serious suggestion. Can you clad and render the front with the pipework behind it.

Bisexual, speaks like a (expletive deleted), acts like a prick.

With an E at the end, I want to be Catholic.

Grow ivy over it.

Welcome. So why radiators upstairs? Many have found with even a basic design, upstairs heating is unnecessary. Do you just suspect the solar gain is going to be a problem, or have you actually modelled it?

Kept me going in the 70s. Such an innocent time.

Solar Thermal is a one trick pony. Once your cylinder is full, it just sits there, close to boiling, waiting to go wrong. PV can be diverted to just about anything electrical, mostly without you knowing why it run at a tiny bit above grid voltage). PV does not need maintenance once fitted. You may find that you can EWI the rear of the building, councils only seemed concerned about what others see. One advantage of IWI is that you can improve airtightness much easier. Old houses are full of holes and leak heat out dreadfully.

Do it before you move in. Get that done, especially if you need to reroof, integrated PV looks better and costs the same. A cavity wall is really a main wall, with the outer as a rainscreen. So be careful about filling it up. They were not really designed with thermal performance in mind.

Webbs. Been at the silicone all night.
