That implies that the maximum temperature does not exceed 27°C, not that the mean temperature, over the whole wooded area, is 27°C.

That becomes a bit tricky to work out as it will depend on many things i.e ∆T, current ventilation rates, solar gain, modulating state of boiler/HP. Best way to test it is to close all windows, vents, put MVHR on low setting, boiler/HP on full/boost and watch the meter and thermometers. But don it on a still night to isolate those variables.

How did you account for evaporation losses if the water? One problem with storing energy in water is that the min and max temperatures are limited. Rocks stay solid over a much greater temperature range. Why storage heaters work. Harder to shift rocks about though, water is easy to pipe and pump. The only good experiments are carefully designed ones to test just one aspect of the material properties, and are repeatable by just about anyone with access to the same equipment.

Boreholes will perform better as the temperature is more stable. Trenched pipework can freeze the ground and this reduces power transfer, this is much less likely to happen with a borehole. There may also be a lot more free flowing ground water deeper down.

Can the type of lights/controllers you are using on the other circuits be sending a 'spike' down the line that is affecting the controllers. Some people pay extra to get 'remote control' of lighting circuits. Usually done over the interweb, but not sure why.

Or water source, get a good CoP from them, as I keep telling the morons are the Jubilee pool who spend over a million doing a geothermal project that failed. They then put in a WSHP. They could have just used a couple and drawn energy from the Atlantic.

Or not. Any store needs direct heating. Relying on natural inputs basically means you get cooling. No one has ever built a large, unheated basement and said 'wow, it is always warmer in here than the house' Others disagree, but it is what I studied at university and I am happy to stick by my findings. If you are considering batteries, may as well add a heat pump, for the costs of 4 kWh of batteries you can get 5 kW of heating.

Be about 30 modules, so 10 kWp. So not particular large. I quickly ran though my location and one near Aberdeen, used 4% as the interest rate, £800/kWp installed price, came out that the levelized costs was 0.046p/kWh and 0.065p/kWh respectively. That was for optimised systems.

Run your best estimate of usage though PVGIS

Is that St. Awful Brewery's New Year offering to go with Big Job, Odd Job, Proper Job and Blow Job, or was that last one just the name of the waitress in the Harbour Inn, Porthleven (actually has a fishing boat named after her).

What is the problem. Veg will grow well with all that blood and bone meal.

Would it be a temperature self regulating type?

That is not so bad. If they were in Chinglish it would be worse. Or IKEA could have written them.

Called the learning curve.

I will do that next month. It won't be what you want, or need, and probably won't perform very well. But I will make £3k out of it. Or They are doing it to comply with ECO rules/targets and will only install them in places that are suitable, and may be very low quality installations.

That really is not enough. Not even sure it would meet building regs.

Parents has a pub in Winslow. Was a scummy, run down place back in those days.

Yes They are the ones that set fire to the wrong building in PZ I think. Twats. "An Gof was a militant Cornish nationalist group that made its presence known in December of 1980 when the organization detonated a bomb at a courthouse in the Cornish town of St. Austell. This attack was followed in January of 1981 by the firebombing of a hair salon in the Cornish town of Penzance (Apparently, the hair salon was mistaken for a bank the group wished to attack – the Bristol and West Building Society)."

She may have been conned by an irritating little fart.

Did you calculate your HDDs or use https://www.degreedays.net/ Dorset is pretty sunny.

Yes, but I think the running costs are relatively low. That is the major selling point of nuclear. Like @SuperJohnG, I like nuclear, but the costs soon run away. The cost of decommissioning is also in the strike price, and who can tell what those will be in 60 years time.

£11bn/GW. If it lasts 60 years, and generates all the time, that is 2p/kWh (I think). Strike Price was about £92.50/MWh, 9.25p/kWh. Still a good deal if I have worked it out right (for EDF).

Not when the English get there. Many English people move down here, most soon move back.

I think we have had the large falls in price. Normal inflationary rises can be expected, part of which is caused by energy prices. https://www.iea.org/data-and-statistics/charts/evolution-of-solar-pv-module-cost-by-data-source-1970-2020
