Concrete and steel are about 3 times the density of water. Water though, can easily run downhill, in a suitable pipe, and any angle.

Why not just pump water up and down an old water tower. Lower embodied carbon footprint.

Well spotted. Would make more sense.

Seems an odd choice of gas. I think CO2 is only liquid in a very narrow pressure/temperature band, the critical point. Though for CO2 that is a reasonable 304K and 7.4 MPa, so maybe that is the reason. Easy to store at 30°C and 7.3 Atmosphere. Lightweight kit. Edit: Whoops, DuckDuckGo saw MPa as mPa, so 1073 PSI, or 73 Atms. Still not extreme.

Just to make it clear, Your HP produced nothing, but drew 313W for the day. 7.5 kWh or around £2.25 at 30p/kWh. What make and model HP you got?

Yes. I retired over 20 years ago.

If you know what fabric you want to use, buy a roll of cable, and get a seamstress to make up some fabric tubes. Then feed the cable through them. Terminate with the RJ plugs. Cross post with @Temp

If you zoom in to the bottom left corner, the sea is brown. Can tell holiday week is over, cheapskate holiday park owners have discharged the sewage treatment plant. And this is in one of the most desirable places in Cornwall.

You need a mood room.

Who knows. I put old soil in the bottom of the pot, then filled up the rest with cheap compost. Just pushed the pips in to thumb depth, smoothed of the surface with my palm. Then watered. I plant loads of things, some work, some don't. All a bit of a lottery. My potatoe garden is just some old potatoes that were sprouting, cut into quarters and buried.

Called bolts. I have often wondered how to make a wobbly wall flat with battening. Probably worth getting a couple if long straight edges. And string.

AJA a nob. You planted your seeds yet?

How long do they have to enforce breaches?

Good. I want to discuss EWI with them. Save me the bother of calling them

I have often thought HPs could have 2 or 3 compressors in them. Compressors are not expensive.

Yes. Why I always put my seed in the lady neighbour's garden. Technically the front doors are in a breach of planning. Meant to be the old timber ones. But as they are a similar colour, council has not said anything. The joys of living in heritage area. Architects can convince the council of any dull looking box, then we, as owners, can't change jack shit. Even the satalite dishes and garden sheds are not allowed. Anyone that has lived in a mining area will know that 'heritage' actually means run down industrial wasteland, complete with toxic chemicals and poisoned watercourses. Heritage, my (expletive deleted)ing arse, just an excuse to not improve an area.

If you look on the Elexon website you can see how cheap excess Scottish wind power is, and how expensive emergency extra generation is. Large scale storage is much cheaper than domestic level, though I do think if most houses had 1 kWh of storage that could deliver at 3 kW of power, that would be very useful. It would be owned by the power companies, rather than the householder. That way people cannot tinker with it.

Well that is my 17 pips of beans planted. Let's see what happens.

It is too thin to add any insulation value. Thermal conductivity (k) has the unit W/(m.K) Thermal resistance (R) is the thickness of the material divided by the conductivity. m/(W/(m.K), more usually written as l (lower case L). Then the U Value, the unit we more naturally understand, is 1/R.

Well so far I have drawn a blank with people in the industry knowing anything about it. But then no one has looked. A couple more people to chat to, hopefully one will allow me to put a proper power meter on one. We shall see.

Going to take me more than 2 minutes to look at it. Wish they would put it all in a spreadsheet.

No, got the light bulb manual. Seem to have missed the CoolEnergy one. was it by PM?

I am really hoping that @LA3222 has just got some spurious readings or this is a serious problem that needs a fix.

Fluttering your eyelids won't get you extra marks, did not help Angela Rainer. Did you make any assumption on the time to heat i.e. DHW heating for 5 hours, CH on for 14 hours.
