Someone on here put their ASHP on a flat roof. Bit if searching should find it. Was @Marvin

I cannot answer that as I know nothing at all about that ASHP, or the combi you currently have. What I can say is that some days it will be cheaper.

The SA may need a higher input temperature, so it can kill the CoP.

Try paying 8 quid a cubic metre for water and waste. That makes it a lot less arbitrary. Then watch up country folks let their dogs shit on the beach, which I pay to keep clean. Give people 40lt of 40⁰C a day.

Yes, or just the I door pump if a split system. That would not be very large and any noise would be outside.

Oil is probably one of the cheaper options.

Just skimmed though the thread. Can you build a shed outside to hold some of the gubbins. A well insulated shed that is.

Has your MVHR pulled in the healthy smell of particulates from the clean rural air yet.

You could just do it properly and fit the right size bath. You can get kits to add bubbles to your tub, and other body parts. https://www.whirlpoolexpress.co.uk/insitu.htm

A car is limited to 74 dB, so something don't seem right.

Just to make it confusing 1 ng·s−1·m−2·Pa−1 ≈ 0.0174784 US perms 1 kg·s−1·m−2·Pa−1 ≈ 1.74784x1010 US perms

You cannot have a claim of ownership if the person that sold you the goods does not have the capacity to pass that ownership on. Life would be a joke if anyone could sell anything not belonging to them, and the person who passed over the cash can just claim 'I paid for it'. If that was the case, then I claim to have bought the whole of the UK, and I am about to send out the ground rent invoices. So pay up.

Don't even need the CT1. We made some tooling for emergency housing that were sprayed PU. Just a dome, on a turntable, and a man with a PU spraying machine. Great idea. Small to ship, easy to setup, very easy to manufacture. Never took off.

You can't spank your mates either, even if they want you to. R V Brown 1994 A much more interesting case than Ryland V Fletcher or Nash v Inman, which has no relevance here at all. I do seem to remember there was an interesting case where some protesters damaged some military equipment. They got off because by damaging the planes (I think it was) they had saved a greater crime being committed i.e. dropping bombs. But I don't think putting up white or brown tiles/cladding falls into this group.

A 1970's house with missing insulation. There must have been some industrial action happening. Now the really messy work starts.

You could plumb in a plate heat exchanger, say a 50 kW one, Then run whatever you want off of that. No ned for an extra storage cylinder.

Yes, this is always the problem, and we are still, on electricity, paying a premium for installing new RE, but the gas network is not contributing much to it. For twenty years everyone has known that a carbon tax is the way to go, but each government has be too scared to introduce it, so they have this sneaky tax what most people do not realise. A 1p/kWh would have raised around £16.5bn in 2019. Dirt cheap.

So is the national Grid. We are close to 50% RE now, and we get that very reliably for 20p/kWh, with no large upfront cost, and no replace costs. I do understand the charm of energy self sufficiency, but the huge upfront, and maintenance costs are off putting. Even with my low energy usage <5 MWh per year, it is not worth me swapping out my storage heaters for a wet ASHP. A2A is marginal. I keep meaning to look at just fitting PV to heat my water. If I had a bigger house, the whole thing would be easier, but with a 4m by 8m footprint, and the half the roof being SW facing, options are limited.

To me that points more and more towards a serious air leak or in the parlance, thermal bypass. Maybe see if the room is noisier. Can get a phone app to measure it.

Well that is not excessive. Is a fan blade damaged.

From the Wikipedia page.. It may be carcinogenic, as it has been linked to cancer of the lungs, liver, and pancreas in laboratory animals.[28] Other animal studies showed breast cancer and salivary gland cancer. Research is not yet clear as to what levels may be carcinogenic.[1][23] DCM crosses the placenta but fetal toxicity in women who are exposed to it during pregnancy has not been proven.[29] In animal experiments, it was fetotoxic at doses that were maternally toxic but no teratogenic effects were seen. I think the word 'may' is the important one. Probably get the same warning for acetone.

What is your DHW temperature set to?

And the processing, I don't think Craig Jones looked the larger picture. One of the problems is that processing wool into insulation is a very small scale business, and anything that is small scale has high fixed overheads.

Murderers!!

Are you PV modules going to get shading from the trees on them?
