So the government has been listening to me when I say 'for every rule we have that says we must do something, we have other rules that say we cannot do it's.

Are you saying that you are going to drill more holes in the joist for the coach bolts? Why not use an adhesive to attach the plywood?

Welcome. The wall thickness makes no material difference to how you calculate heat losses. Start by accurately measuring the house, those dimensions will be useful to work out where the biggest losses are from.

Many things, spent most of my working life in the plastics processing industry. My main interest was in reinforced polymers though.

Welcome Claire. I have been slowly improving the thermal performance of my home over the last 20 years. What sort of information are you after?

I have often wondered what they are like as they would be a good replacement for one of my storage heaters. Get one and report back. Just had a look on Reddit and the make, not that particular model, seems to get good comments. I think like a lot of things, how they are used can affect reliability.

Had the same problems when using them with resins. I found away around it, but way too expensive as it used fused silica (aerogel), and would not work, chemically, with cement. There is a way to make concrete mixes foam by using aluminium powder, and then autoclaving it. We now know that it can fail. https://www.chaluminium.com/using-aluminum-powder-in-concrete-processes-and-impacts It should be possible to insert a foam core before casting, this is pretty common in plastic moulding. Multi pour casting methods are not uncommon either. It is really good that you are doing this, not enough people come up with ideas and experiment, fail, improve the design, experiment again...

Does here, in a way. https://ebac.com/heatpumps So about £8,000

Been a while since I have looked at contract law. But this may help. A4ID-english-contract-law-at-a-glance.pdf

Several years of experience tells me that this may not be 100% accurate You have to remember that the French copy nobody. How we got the Citroen DS.

It is the same fluid mechanics. I seem to remember that air and water have similar fluid properties even though the densities are different.

You can get needle valves that have a linear response. You can get them to respond to just about any curve you want. Used in carburettors a lot, and they meter incredibly well considering. There are many different designs, some for mass, some for flow, pressure, temperature compensation even. Engineers are clever like that.

The first timer I bought, cheap on eBay, did not last long. It did fail safe though. I spent an hour in B&Q looking at them, then bought the above cheaper online.

I just use a basic digital timer. Been in over 15 years now, no issues. It is a Selectric Energy Saver Model Number LG-DIHT https://www.amazon.co.uk/DIGITAL-IMMERSION-HEATER-TIMER-LG-DIHT/dp/B0066NEBO6

There is.

If you point an IR thermometer at panels, then the one with the highest temperature will be the failed one.

Reform UK sets out plan to tax renewable energy Image source, PA Media Published 25 minutes ago Joshua Nevett Political reporter Harry Farley Political correspondent Reform UK would impose taxes on the renewable energy sector, under its plans to scrap the country's net zero target, the party's deputy leader Richard Tice has said. Tice argued net-zero policies were to blame for higher energy bills and deindustrialisation in the UK. He said renewable energy was a "massive con" and promised Reform would recover money paid in subsidies to wind and solar companies. "The British people are being ripped off by the renewables industry," Tice told a news conference. He suggested a "generation tax" and a "special corporation tax" would cover the costs of government funding for renewable energy. "The British people need to know there is a direct link between the cost of all these subsidies to the vested interests in the renewables industry and your bills," the Boston and Skegness MP said. The party did not share further details about how the taxes would work in practice, including at what rate renewables would be taxed, or how much revenue would be raised. Tice also announced plans to tax solar farms, and pass new laws to put energy cables underground rather than on pylons. Reform's deputy leader said "we will scrap net stupid zero" if the party won the next general election. Currently, the rebranded Brexit Party has five MPs after winning 14% of the vote nationally in last year's general election. Cooling on net zero The party's position on energy and net zero contrasts starkly with that of the Labour government, which wants to remove nearly all fossil fuels from UK electricity production by 2030. Labour is expanding renewable energy and said in its election manifesto it would invest £8.3bn in Great British Energy, a state-owned clean energy company, over five years. Governments worldwide are investing in renewables to meet international climate targets and lower carbon emissions to "net zero" by 2050. Electricity is increasingly generated from renewable energy in the UK, and the cost of renewable generation has significantly fallen in the past decade. Labour promised to bring down household energy bills by "up to £300 by 2030" - and Energy Secretary Ed Miliband has stood by the pledge. But UK energy bills went up in January, external, and are expected to rise again in April. The main reason for high energy prices in the UK has been an increase in the price of gas, which has been the largest source of fuel for years. With energy costs on the up, and President Donald Trump promising to drill for more fossil fuels in the US, Reform UK has turned its focus on the cost of renewables. What does net zero mean? Published 12 November 2024 If the UK has more renewable energy, why aren't bills coming down? Published 5 days ago High energy prices predicted to be 'the new normal' Published 18 November 2024 Polling consistently suggests most people support net-zero policies and are concerned about the environment. But standing alongside his deputy, Reform's leader Nigel Farage said it was "irrelevant" whether he thought climate change was real. He argued anything the UK did would be dwarfed by the scale of carbon emissions in other countries, such as China and India. Sam Hall, director of the Conservative Environment Network, said Reform UK's plans "would cause household bills to skyrocket and pull the rug on energy firms". "We should be unleashing homegrown energy that can make us more energy secure and self-reliant, not blocking new supply and decimating investor confidence," he said. He added the problem was "not net zero, it is our reliance on expensive gas imports and excessive government intervention in energy markets".

So posh TRVs then. Not so different from what @DamonHD was doing, one radiator at a time.

That looks like a roof that is not going to be affected by shading, though I cannot see it all. Is there a real reason to fit optimisers on it, rather than just allow the built in bypass diodes to do the work of disconnecting shaded parts.

Into his skip I think. Told you he was a (expletive deleted).

Welcome back Jim. @Pocster is still a (expletive deleted).

Thanks.

Do you fancy uploading the code to my blog, then I shall see if I can make one.

Did you ever pick up that ESP32 meter based on my design again?
