An hour less than the check in time before a flight. I hate flying.

Check the efficiency on a regular basis. It will be interesting to see how the performance drops off over time. Temperature may make a difference as well. I should be passing though the Cotswolds tomorrow.

I would say post up picture, but maybe not.

If a person expels 0.7 kg of CO2 a day, and a house, 10m by 6 m by 5 m, has 300 m3 of air in it, that is 375 kg of air. After a day, one person would have increased by CO2 by 0.18%. So about 5 days to start noticing anything. Or a day for 5 people. Apollo 13 got back OK, and they had greater problems than just CO2.

That's interesting. On what sort of depth of discharge is that. Say it is a mean of 50% (down to 25% and up to 85%), then that is 7.75 kWh input. 76% of that is 5.89 kWh output. 1.86 kWh 'missing'. I think my DHW cylinder is better than that.

Do you mean 15 MWh/year? I am not sure, but the old Leafs had pretty rubbish batteries and this is why they are sold off cheap. You may find that for every 10 kWh you put in, you only get 4 kWh out, and, a lot of low temperature thermal energy when changing. I would like to see some real numbers in using a cheap EV battery, especially if the thermal management system is disconnected.

I bet the batteries don't come down by 20%.

It is kWh. kW is the power, kWh is the stored energy.

Or a 20 quid fan heater at ground level.

They are brilliant for heating air, at roof level.

The manufacturers/retailers/installers would just treat that as a subsidy and increase their prices. It is what happened during the banking crisis when VAT was reduced. I would put the VAT up on fossil fuels and add on a carbon tax. It can. But most houses probably need much simpler fixes to get large gains. Re-glasing my old timber windows was about £20 a window, the old 8mm gap panes were blown, so cost the same to put 16mm gap ones in. Was not enough frame area to worry about thermally. And I have nicer looking windows compared to my neighbour's plastic framed ones. I would think that most 'leaky' houses have one or two major leaks, not hundreds.

Hornsea 3 is going ahead.

Why, and how does it make people poorer? It is just moving capital from one industry to another. A million people working in the oil industry or working in the renewable energy industry, is the same thing. Remember when computers were going to take all our jobs? Printer sales expanded, as did IT support workers.

Of cause we can stop it. We know what the problem is, what is he solutions are, and how to pay for it. Just a matter of getting on with it, just like it has been for 30 years.

Kerosene is all good that is needed. Burn the sun out of the sky. Montol tonight. VID_20231221_184357914.mp4

TL:DR There was someone on here who took down one too many walls and got clobbered by the planners. Either scale back your plans or start a fresh. No real middle ground here.

Does it (expletive deleted). I camped out by a babbling brook once. Noise kept me awake all night. I now look for places with familiar sounds to camp near. It is the absence of normal you have to be wary off.

I don't think that IR heating will help keep the humidity down, so tools will rust quicker. If you can make use of ToU tariffs, then stick old storage heaters in. Can get them for nothing.

There you go. You have a badly designed/sized system. You can't tar all ASHPs with the same brush.

You can take just about any literate person of the street and train them up in a few weeks to be useful to a more esperienced plumber. There is a general problem with employers. They often complain that graduates (at any level) don't have the necessary skills. So they want a young person, with a decades experience, and probably qualified to Masters level, for minimum wage on a zero hours contract. That is the biggest problem, employer expectations.

According to this https://www.statista.com/statistics/1228145/plumbing-and-hvac-company-number-in-great-britain/ there are about 40k companies that do plumbing and HVAC. If the demand was there, then each company could take on an extra half person, so another 20k of fitters. If they could replace 1 gas boiler to a heat pump twice a week, then that would be 10k of extra capacity, half a million extra installs on top of what is currently being done. If there was the political/public will to actually change, rather than the current will, with spurious arguments not to change, changing 2 million installation a year should be possible. With about 30 million home, that would take 15 years. I shall just leave this chart here, I have highlighted what it was like 15 years ago https://www.ncei.noaa.gov/access/monitoring/climate-at-a-glance/global/time-series

Care to share the link?

Just do it for a laugh. What I do.

Seems to me just about everything is connected, usually via a third party server. Your best bet is probably a couple of fan heaters, they are quick to heat a place up as they force the air though. £100 buys about 300 kWh of electricity. That is about what I have used in my house over the last 30 days, and I only have resistance heating.

That can give you other problems. Polystyrene can degrade the PVC insulation.
