just check the wired adaptor isn't disabled in Windows

The copper flexys are handy sometimes. Our chinese friends offer convoluted stainless tube (similar to the tracpipe or the flexy solar stuff) in short lengths with flat faced ends for a few quid a touch, they're quite nice too. Same is used inside UVCs as the HE coil this kinda thing: https://www.aliexpress.com/item/1005002680190702.html

still that's enough to upset the match as the illumination is quite oblique. Turning the sample 90degs would likely give a very different result. / with the automotive spectros, there are instructions from each paint manufacturer on what type/ grade of polish to clean the surface before reading, etc.

who does free returns...

the spectros that are used for domestic matching are massively different to those used for cars etc. Was the sample board rollered or brush-painted? Much texture?

@Russdl how are you "cleaning" the charcoal filter?

...and don't drill through the pipes when mounting it.

so you currently have two fibre modems?

so what was the tank temp and the setpoint?

@HughF what kind of changeover valve do you use?

you can generally leave the insert in-situ and push the new pipe in, over the insert.

snap!

possibly a mains spike that got through the rectifier? Both the fan and the main drive inverter are on the same bus so I'd guess that anything that disables the inverter crashes the fan module too.

@ToughButterCup does your chapter and verse apply to all four devolved regions?

might you be able to sneak a camera in to check the cavity tray over the window for gaps or holes too?

bit late to be calling him an "iddiot" now. Why didn't you query it?

2. I put a supply in the pantry in the hope of keeping heat from the surrounding rooms at bay. It helps... a little.

if there's water coming out of the schrader valve then the pressure vessed is FUBAR. Simples. Replace it before you try to hunt down any other ghosts...

It's my experience that thermal trips degrade with the increasing number of trip/reset cycles. It might've been on the bitter edge for years but now that it's tripped a few times it'll go a bit more easily. I'd replace it with a 40A and ensure there's no evidence of heat damage on the cable ends, and re-try.

pull the wall down and rebuild with an undamaged cavity tray *and* weep vents in the correct place / are you sure the vents were fitted properly and not cut in half/shoved in a drilled hole as bodgers have done in the past?

plenty of colour-coded adapter cables then, the only query looks like the ribbon cable?

if the original item is obsoleted for whatever reason (component shortage post-COVID is common...) I'd expect the replacement to be a direct swap and if not come with instructions.

so how would you propose pushing improvements to the housing stock?

https://uk.yahoo.com/news/military-shuns-heat-pumps-favour-153414975.html "An MoD spokesperson said that the project was launched to find a cheaper alternative to heat pumps, which require comprehensive and expensive work to a property before installation. One possible solution is by using Cylo boilers, which the Telegraph understands are currently being fitted in four homes at the Duke of Gloucester Barracks in South Cerney, Glos, as part of a pilot project due to start early in 2024. Cylo is a fridge-sized, emission-free electric boiler that is cheaper to run and more effective than a heat pump. It is also greener than a gas boiler and requires no major works to a building before it can be installed. The boiler uses a pressurised water tank as a thermal battery, using off-peak and cheap electricity to create a “heat reservoir” that then powers radiators when needed. Standing around 6ft tall and weighing around 250kg before being filled with water, it can be fitted in a ground floor room or on the outside of a building.!" really?
