Saw a design that used a central heating water pump. At least all the bits are off the shelf.

Make a waterwheel connected to a small generator. True green power.

Air changes an hour as well (with and without heat recovery).

Was it easy getting it though planning?

I am not to sure about that timing. Come October, we are having money borrowed against our bills, then we have to start paying it back over the next few years. October is the time to massively reduce usage until others have paid off our loan. (expletive deleted)ing bonkers idea allowing it, I hope it gets challenged and an opt out is offered.

Does he just do he electrical side? or actually install systems?

Covers all sorts of things, including staff monitoring. It is a comprehensive scheme, abused rotten. And the built in insurance/warrantee/guarantee is a joke. Used to be called REAL, but I doubt anyone ever successful claimed on it. Probably called something else now.

Sounds very dodgy to me. Cost 100 quid to drive 300 miles in a van, and how do they check the structural integrity, rely on an unknown SE (printing up letterheads now, every town has a Number 3 Church Street).

As Siberian Larch grows on the Finnish boarder, do the Fins sell it. Get in quick before they join NATO.

Pretty sure wiring regs say it must for mechanical damage protection. @ProDave can check. I seem to remember that 80V at 1/8th of an amp was enough to kill. Same as 1 kg moving at 1 m/s. Or 1 g moving at 1000 m/s, which is a bullet. (May not be the actual numbers but you get the picture, I am more interested in the conversation on the next table, couple of Emmet that 'love the place' and want to buy a holiday home)

Sounds like a case if patch or replace. Water vapour behaved like a gas, because it is a gas. Liquid water is more affected by gravity, the DPM deals with both. Holes in it means it fails for both. Now go and find what ham fisted plonker broke it. Give them a building physics book and test them on it.

NO. Just make sure it is the correct size, and you operate the system correctly.

This is always a problem with technology. I used to lecture in IT, and often met students that had a friend or relative that 'knew everything about computers', then then asked me how to fix something. That incident with the DC isolator was actually caused by the module fitter adding an extra couple of modules, 'to do the customer a favour'. Still think the sparky should have checked the numbers there first. Bet he does now.

Just don't use the DC isolator to disconnect the system when it is running. Switch of the AC side first. Ask my old electrician what happens. Told the customer it was some 'dust on the contacts'.

Life gets better and better.

is this about fitting really, or

Good spot. I have bought one. £21 with delivery. Next time I leave my shed light on, I will only be burning 40W rather than 125W.

Power delivery will be almost linear, the power needed will not i.e a smokey woodburner and a window open. But I think if you divide a heating curve by an equation of a strait line, where C is the offset, you get close enough to a straight line. Probably more problematic in a small house than a large one. Seems odd for the price of a sensor not to have at least 1 roomstat, then a fully automatic system can easily self learn.

There will be weed seeds in the new top soil, and some will blow in as the grass is growing. Also, if you put a weed control comer down, you cannot easily plants some early flowering bulbs.

I spell most words wrong. Why I hate English as a language. BSL is much more sensible.

Chips can be filled with coloured car body filler. Scratches tend to just vanish with age, and bird shit.

Takes a few thousand years for a body to fossilise in the right conditions. How long do you want them to last.

Who said that?

The same brickies that know nothing about airtightness, and usually get the window openings wrong. Quite impressed with @pocster's solution, quick and easy, and he had the rebar kicking about (cause he ain't got a clue how to use a tape measure yet, the final coping stone won't fit).
