It is to do with geology. Not enough artisan wells, or chalk. Cornwall and Devon are a chain of extinct volcanoes after all. Cleaning up water from deep wells is problematic in a radioactive area, as is cleaning up river water in a heavily farmed area. That is before the residues of 2000 years of tin, copper and arsenic mining is dealt with. There is a reason that Backwater and Red River are names as such.

When analysing PV output, UTC, which is just GMT, makes the most sense. Not as if the altitude and azimuth of the sun will suddenly jump to match the stupid clock change. Noon should be Solar Noon, no matter where you are.

They should have put a candidate up against George Eustice. Camborne residences would have voted for them.

Still have a hosepipe ban in Cornwall. Water reserves are not a function of just one winters rainfall.

Oh, the famous ''Up To". Copper has an embodies CO2e content of between 2 and 4 kg/kg. Mineral Wool is around 1.2 Polyurethane around 4 Polystyrene around 3 So pick your insulation carefully as I suspect there is a greater tonnage of insulation in a typical UK house than there is a mass of heat pumps.

Which, in itself, is (expletive deleted)ing odd. How can a fundamental particle, the electron, become a political football. About time most people realised that the electrons jiggling in wires care nothing for peoples political views.

And they do not want to be reliant on other countries energy sources. Japan has always had to import the vast majority of their energy, what are the current costs of domestic energy there?

Nice idea. How would all the countries of the world agree that tariff free trade on food production needs to happen, and in an unhampered manner. The UK can't even agree on that with Northern Ireland. So 43% of our electricity, in 2020 was from low carbon sources. Installed capacity is up about 3.5 times between 2011 and 2018, generation over 4 times in the same period. The physical infrastructure, or price, is not the problem. We did not have a European war in 2018, and in fact we had historically low energy prices. I really don't understand the general public's dislike of renewable generation. They seem to dislike, but accept, the current high prices, but don't want to change anything.

Not really the surface temperature of the heat source, or the overall power. It is to do with the frequency of the photons emitted. There term 'hotter' or cooler is used to hoodwink the uneducated.

Is this 'scientific' presentation just this reworked again, again, again... Global Warming Hiatus Anyone here the news about sea temperatures this morning? Also, shall mention that temperature and energy are not the same thing. The Earth's Energy Budget is currently positive i.e. more energy coming in than going out.

This 'visible from road' which is really just saying not at the front of most houses. Does it not rather clash with the noise conditions. Most people's rear gardens are quite than the front ones, because they are shielded from traffic by 100 tonnes of solid mass. It is not unusual for my road to hit 90 dB (one if my neighbours cars is 80 dB when it is ticking over, and 10 metres away). The rear of my house is generally much quieter at night, though when upstairs one can hear the road more as there is a bend and a rise. If I could put an ASHP at the front of my house, the one installation would be much simpler, make no difference to noise levels and be mostly hidden by some pampas grass. Really there needs to be a better way to enforce noise problems if they arise, not try to make one technology a special case.

Hope you mean of the house, not the recently single owner.

Umm Reminds me of school. Those candles, reminds me of my sister's school. "Candles out girls" said matron. POP. Now find the matching shower.

Welcome. There are a few of us in Kernow. Which end and side are you?

How much are the Tigos?

Why not 2, 2 string inverters? Then split up as you were going to.

Get the metal detector out. Though some misguided souls will tell you that divining twigs works, they don't.

I can see about 500 homes at the moment, and a huge liquid heat resource. Shame that it is not used. But if I look in the other direction, I see £1.2m wasted on a geothermal project that failed, then had a GSHP fitted. Why not a WSHP.

@Katie AG Might be worth doing a scaled sketch of what you currently have, putting in the position of the current services, road access etc. There are a multitude of rules and I doubt 1 person knows them all. Why a community like Buildhub is useful.

Run it through ChatGPT. Better still, find the official government act and get that rewritten.

This MCS thing is quite interesting. I once worked for an MCS company. As far as I know, no one employed by the company had any relevant qualifications. Qualified electricians and plumbers were employed for any relevant work, same with scaffolding. Now I know there is now some training/prove of work to be done to get the MCS. So what is to stop a company just getting MCS registered and subbing out the actual work?

Is that similar to @pocster's imaginary hot girlfriend?

SAAB went down. As did Rolls Royce. Blockbuster. Barings Bank. Woolworths.

Emphasis is on the wrong word. 'problem we know we have' Too many people consider it not a problem. Maybe I shall look at the economics of payback periods. Oh hang on, Stern did that 17 years ago. May be worth rereading and seeing how it has stood the test of time.

Loads. How many people think turning the thermostat up will heat the building faster. 50% How many people think that turning the heating off means it must use less energy the next time it is run? Lots. Try explaining how a heating system is meant to be set up and work is not an easy task. Silly terms like 'thermal mass' and 'solar gain' soon enter the conversation. But I was not really refering to that. So yes, there needs to be a visible temperature control, and a standard to modulate that is universal. It does not matter how any particular type, make it model actually does its thing, just that the user and communication protocol is the same. Probably as simple as setting just the maximum flow temperature and the minimum return temperature. With those two, the highest power can be delivered, and the difference between the flow and return sets the efficiency.
