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.

Does seem that control systems are the main problem, for both installers and users. Maybe a new thread to discus the best way to design a control system is needed. I was chatting to a plumber last night, asked if he did HPs, said he was going to avoid them for the time being. I mentioned that many customers will need education as they are not used like gas boilers i.e. whack in 25 kW for a few minutes, then switch off (even though a well buffered and modulating system should not run like this). He said ''good luck with that". So is the real problem an educational one?

Enough party members voted for Truss, so Trump is unneeded as the Truss legacy is still carrying on.

Really. So recent US events concerning women's fertility don't bother you at all?

I have done jury service. If you want to see ignorance of the law, unbridled hatred of certain groups of people, having to put up with the workshy who prefer being in a clean and cosy courthouse as they get paid the same as working in the cold meat processing factory, a self elected jury foreman that had egotistical and bullying tendencies. And one bloke that had an IQ if probably 75. Plus half of the jury doing private research i.e. googling and discussing with 'outsiders'. Swapping evidence, as presented in court for opinion, scenarios and by bigotry was normal. Then, all but two of us, totally ignored the judges guidance, and found the person guilty. The guidance was that the the witnesses had been made to lie by the plaintiff, and the plaintiff was unreliable. Even the police said the plaintiff was a fantasist and had accused many people in the past. Jury trails, no (expletive deleted)ing way, it is as corrupt as the target driven CPS. 30 years since Steven Lawrence for murdered. The spotlight is on the MET, not on the thugs that did the crime. 30 (expletive deleted)ing years, half my life. Only 2 or the 5 suspected of the murder got locked up.

Except as resent events has shown, sending a few emails is considered good enough for customer contact, then the forcibly fit a smart meter, then remotely disconnect the customer. Hopefully that policy has now changed.

They are probably only going to pick the very easiest installs, the ones that could be done by almost anyone.

TL;DR This may have been answered, but shall say it anyway. The reason that heat pumps are being promoted is that they are mature technology. The reason that heat pumps are going to be fitted is because they can reduce, quite significantly, our domestic CO2 emissions. The rate of fitting HPs will go hand in hand with renewable electrical generation. Global emissions from electrical generation may well peak this year. https://www.newscientist.com/article/2368526-emissions-from-global-electricity-generation-may-have-now-peaked/ I think most high temperature HPs use supplementary resistance heating for the final 10°C or so, so not really high temperature at all. It has been a long day, but I try not to smoke too much hopium or unobtainium.

That is good, won't affect PV generation.

Why I like to monitor my own usage locally, and keep it to myself (except what I share on here). https://forum.buildhub.org.uk/blogs/entry/946-the-energy-meter-experiment/

Do they make that 50 quid you get for introducing a friend by misreading the meters? I suspect the Pareto rule applies, 20% of customers have 80% of the problems.

Not for me, meant school was out and I did not have to kill time in Witney.

There is also a difference in OAT depending on how near the coast you are. It is a very rare event if the temperature drops to 0⁰C down here, and even rarer it goes above 24⁰C. That is for the warmest region in the UK. Go to Central England, below freezing, is not unusual, above 26⁰C happens fairly often I am told. So allowing for natural ventilation will depend on the likelihood of high OAT, sun angles, time if year and duration of the above events happening. Bloody horrible down here at the moment.

idiōtēs Greek for ones own.

Here I am

Seems to be the same, almost.

Because the AH is different. 3.164g/m3 at 75 RH and -2⁰C compared to 4.403g/m3 at 94 RH and 0.5⁰C. So 72‰ more actual water to condense and freeze.

Do you have a link to the regional prices. Be interesting to see what they are charging in one of the poorest places in the UK.
