Which is near enough 5.1 kg/m2

Not if you use a large tap.

Run a lathe in reverse for LH thread cutting.

Worth looking at the current rates on E7/10 as they are not so attractive. Think mine are 14p and 24p. I use around 80% of my energy at 14p. But my usage is low at ~5 MWh/year for everything. Usually only use about 2 KWh/day at 24p.

About the same as car sales then. https://www.best-selling-cars.com/britain-uk/2020-full-year-britain-new-car-market-overview-and-analysis/ A quick look at the ONS data shows 3,800 people employed in the retail and repair of motor vehicles (which feels to me a small number, but no matter). These people probably have the skills, after retraining, to help fit HPs. They would have to fit 450 system each year, do 10 a week. So not an insurmountable challenge, but not easy. These points have been made before by Al Gore (in 2006) and David MacKay (in 2008). Banging on about who is going to pay and who is going to make, and fit the systems is not the problem. We have had 20 years of knowing about this, there just seems a real reluctance to change. This is not helped by the trade and media saying that HPs are only for modern houses built to the latest specifications. That is like saying only modern cars can tow a trailer. And the statement that HPs are only truely carbon neutral, in operation, if our electricity supply is only truely renewable, is just a diversion. Don't let energy of the best be the better.

Good project management and knowing where the end point is. I read an interesting book about the Apollo project a few years back. The one thing I remember was that they made the big decisions first i.e. best design of rocket needed. Then worked on the details, which were just implementing existing technology. It worked well.

Check all gutters and drainpipes.

Use lightweight pots and pans. People still think you need heavy pans "to spread the heat". This is just nonsense with even a cheap IH like mine.

I got the perfect answer, one word to. Shame there is a swear filter.

At least no one has mentioned using screws. I had never heard of lubricating nylocs, but seems it is recommended. And it seems they can be reused. I think the important bit is, if the joint is safety critical, is to use the correct washer/s and torque it up correctly.

Can't you rivet it. Or weld it.

Only ever seen stainless steel work areas in all the commercial kitchens I have worked in.

So you have no objections to me contacting Valliant and pointing out that your lack of knowledge about modern heating systems is hampering the performance.

Are you still refusing to use it at night. Or in other words, not using as it is designed to be used? And if you are, have you made it perfectly clear to the installer/ASHP manufacturer that you are using it outside of design parameters?

Cor that’s cheap Always worth shopping about. But my pure guess to pay @Onoff 1500 was not so far out.

What temperature is your room? I have had a quick look at your weather, and a station near me that has similar readings. (Aber Village 87% RH 15.5°C, Mount Hawk 86% RH 16.2°C) My house is currently at 75% RH and 21.7°C Feels fine.

Any help you can borrow it.

Some do. Half the time it is dark, and most of the time people are not looking at the outside if their home.

black powder Bit over the top.

All you need

Commercial ones don't have turntables. They work well. I am told that they don't need them as there is sophisticated electronic jiggery pokery that swirls the magnetic fields around. And you can leave a spoon in a Tupperware full of beans and they still work.

Similar to you then.

I got Monday off, tempted to turn up as well as @joe90. In fact, all of us that are fairly local could turn up. The laugh at the price of the crane.

Think it uses a default number i.e 230g/kWh.

Only millions. I was told, by an expert (well they wore ethnic clothes) that it was all birds. And every bat that has ever existed.
