@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?

can't you just tee it into something else and fit a dri-trap?

check reveals ftw

AI?

so what's a set- screw then?

Is it really a layby or just the mouth of the lane? I think the way it works is that you own right up to the road but DRD have rights to maintain the verge along the sightline

so instead of just being along your sightline, their entrance ends up in the actual mouth of your lane? That would require legal documentation I'd say.

those small diesel IR heaters are great for working on front of, not so good for heating a space. They do run very clean, moreso on kero. But for heating the air you'll not beat the rocket heater type. There are even a few that have a flued combustion chamber so no emissions in the room I recently treated myself to one of the boxed chinese caraven heater jobbies and it's very good. 8kW, sips fuel, haven't even bothered piping the exhaust

^ yep. Looks like black iron screwed onto the brass?

Not necessarily. Our system runs the TS at 50 but the ASHP cuts in and recovers the tank *during* use. Like an electric shower, but with a COP well above unity...
