How to measure the remaining HW in an unvented cylinder
dpmiller replied to Adsibob's topic in Boilers & Hot Water Tanks
so does this mean that the short heating periods youve set might not even be fully satisfying the tank currently?... -
What model is this oil pump - have a guess
dpmiller replied to cwr's topic in Boilers & Hot Water Tanks
the mount and shaft *should* be universal but there are some outliers. Direction of rotation and pipe positions are the critical bit, some of the other options (position of the regulator etc) may not be so important for most applications... -

dpmiller replied to cwr's topic in Boilers & Hot Water Tanks
tell us what burner and boiler it is, and do you know the direction of rotation? or if you're stuck there's always https://www.bes.co.uk/universal-oil-pump-16393/ -
no they couldn't, no smart meters in NI

*think* isn't good enough, what's the number? Buildup?

Radiators not reaching flow temperature
dpmiller replied to Helene's topic in Air Source Heat Pumps (ASHP)
coz they fail often and drip gently. When working fine, you'll get a small volume of trapped air- at system pressure- above the internal float that'll hiss impressively when you slacken the schrader cap. -
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.

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?

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

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.

Void and Pantry and More
dpmiller replied to Mr Blobby's topic in Mechanical Ventilation with Heat Recovery (MVHR)
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...
