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...

people keep saying this, anyway.

what size is the installed cable for the cooker?

we're doing the E7 ASHP/ boiler stove combo too, and this year I'm trialing using the immersion diverter towards the end of the E7 period to get some extra heat in the TS without troubling the heat pump with excessive defrosts. I've also increased the room temp a degree to charge the screed a bit more. Stove isn't fired every evening but when it is, 3-4 hours makes for a cozy room to watch telly in and adds about 15c to the TS

why?

where do you live- Beiruit? The Bronx?

while you can certainly get drill bits with a 1/4" hex mount few are for masonry. Bosch Multiconstruction bits or similar will do it, but as you've no hammer action to assist it'll be slowish going https://its.co.uk/power-tool-accessories/drill-bits/multi-construction-drill-bits/ or here's a yellow option if you prefer https://www.amazon.co.uk/Dewalt-Multi-Purpose-Pieces-DT60099-QZ-Shock-Proof/dp/B01JYO15B0/

in that particular section, wouldn't the steel lintel be acting as firestop? up the sides of the window, or if using a concrete head, would be different...

pictures of the manifolds? and what are all the wires on the RHS connecting together to? what thermostats do you have? there's at least three zone valves, two pumps, and a buffer. That makes around eleventy million different options... And yes, get some insulation on those pipes. You're wasting a shedload of heat there and it sure won't be helping you get everything up to temp..
