So Quantum Physics and Relavalistic Effect not exist then, or been written about. How it all moves forward, but I suspect the underlaying causes are the same. There is a methodology to science proofs that has not yet been bettered. There have been a number of academic that have tried to rewrite the science method, they all fall down in the end. I think the biggest problem is that when describing nature, models are used. At the early stages of peoples education, these are very simplistic models, the 'don't touch, it is hot' level. These move on a bit at school to putting a few words and maybe some theory to it i.e. temperature, energy, molecular movement. And for most people that is where it stops. This is why people still think low temperature, or low voltage, is equal to low energy, even though, they don't have a clue what energy is. Much of this confusion has come about because of the social and medial sciences. Trouble is, their burden of proof, or what us real scientists call truth, is so pitifully low i.e. a 95% confidence level, compared to 0.0000003% or nearly 17 million times less chance that it is a fluke. Also, when an idea is rejected, i.e. the research is on the wrong track, that does not prove any alternative is correct. So a simple medical experiment to see if taking a daily Aspirin reduces blood clotting, does not show anything about that not taking Aspirin. This is something that social and pseudo scientists, and especially pub bores do not adhere to at all. They use a negative result to show a proof in any other area that that fits their believes. This is hardly surprising as we have all been brought up a religious societies that thrive on 'absence of evidence is not evidence of absence', which when you think about it, is a nonsense statement.

But a few minutes with the correct solvent, which is not acetone, would have solved it on site. I have told people what to buy for years, but no, seems everyone wants to carry on using acetone.

You have no intention of ever modifying it then.

You can wash it away easily with this.

But the RMP is generally low. It is extremely rare that they are running at full fan speed. I used to live in a rally isolated, rural place, all I could hear was my tinnitus most of the time. I hated it, any unexpected noise just worried me. I had the radio on 24/7 to mask the silence. Oddly though, my sister, who is pretty deaf, hated the 'rural' noise when she moved to the country 'for peace and quiet'. I did warn her that agriculture was not silent.

Wasn't it electrical resistance heating that caused problems. @TerryE only has resistance heating.

Same reason as this.

Not been the experience of people, on here, that have properly designed system.

Good stuff

Or just create a new house in the metaverse.

My view is that a buffer would always be designed in with a heat pump system.

Generally it is the proportion of fillers that reduce shrinkage in PU foams. We used to add on 3% for shrinkage when moulding cushions and dashboards. But it was also affected by ambient conditions when moulding, tool temperature, raw material stock temperature. I have always been concerned about shrinkage with SIPs. Seen panels that are bowed at a show and when I questioned the salesperson, he just shrugged.

They are just A2AHPs, so the pull the energy our the air, cool it a bit then expell it to outside. Once you have a tank of hot water, you can do what you like with that, use it as DHW, pipe it into a radiator, plumb in an W2A heat exchanger and pre heat the air coming into the house.

My cheap Acer laptop pulls a maximum of 30W. Most if the time it is just idling with the screen asleep. A few years back I put an energy monitor in it and was really amazed how little it used.

Something like this. Pull the air our if the hot parts with a bit of creative ducting. https://www.directheatingsupplies.co.uk/vaillant-200l-heat-pump-cylinder-20235272

That is enough to heat my whole house. My PC uses 8W

Do you know the actual make up of the walls. I doubt if it is actually 2 foot of solid stone. This may be helpful if you have access. https://www.sciencedirect.com/science/article/abs/pii/S0013795209001434 Air, atmosphere (gas) 0.0262 W.m-1.K-1 Ground or soil, dry area 0.5 W.m-1.K-1 Granite1.7 - 4.0 W.m-1.K-1 Just need to take a stab at what the wall is made from.

Warm up water, or bricks. You get extra energy from the fusion phase, a lot more energy for no change in temperature.

How about ducting in an exhaust air heat pump, then doing something useful with the energy. I wonder if a relatively cheap dehumidifier could be useful.

Have you looked at this document or a newer scotch one. BR_443_(2006_Edition) (1).pdf

Did for me. Here is a 2017 paper. Covers just about everything you need. AQA-PH1FP-QP-JUN17_(1).pdf

Maths and physics GCSE, the full skill set to do a proper heat calculation is covered in those two. Or we could have a £37bn government app.

No, that tastes like Annie Lennox. Or toothpaste.
