push them in afterwards

^ electronically commutated, no capacitor. Doesn't look like it's got any unblocking mode unlike many modern pumps that'll attempt to shake themselves loose if the rotor can't move?

what type of pump is it- fancy multimode thingy with digital display, or old tech with a 3-speed switch and a starting capacitor? Is the water well inhibited?

I'll throw a curveball. 9kw ASHP plus thermal store, thermistor probe halfway down the tank...

umm, that's probably more like 3.5Ah. I've just bought a motorcycle battery about the same size and weight..

still plenty using neons

@Talaidh where in the world are you?

looks like the same flipper as ours. If so, there's a wee screw holds the top cap on, as a pivot

I work in and around both healthcare and scientific research. There is NO DOUBT that poor decisions were made during the rollout of the lockdown. Could things have been done differently? Absolutely. The messaging was horrendous. So many people across the nation suffered massive loss- of family, personal health and mental health. Thus the Enquiry. But the worst thing in my view was indeed the outright disrespect for the nation by those in power who partied, and those that saught to make massive financial gain eg PPE contracts etc. I would love to believe it was all some cynical game, and would have bar one thing- the lead researchers locally who were used as talking heads on the local news etc, who I've known for decades and trust with my life when I'm in a cat3 area servicing their equipment- were sh*tting themselves. These guys who are trained in the safe handling of risks, were scared. Why? Because the normal rules didn't apply. In the lab, you protect yourself, work carefully, clean down safely. Jo Public was walking around with it in the open air...

cut a big hole in the chassis of the unit and let the supply air percolate through it?

B&Q used to keep polystyrene in stock, dunno about nowadays. Does it all need to be window-clear or is twinwall an option for any of it?

I wouldn't expect McMordie's to be the cheapest source ever, but they *do* know their stuff...

smells like a broken wire/ loose connection somewhere in the fitting.

Isn't it nice to just try and tread lightly on the earth?

have I missed any reference the DHW in this?

that would be GB then surely

you're replacing an exsisting tank so just do it. No plumber involvement either, it's just a couple of fittings, plus a plastic tank aint heavy. And whatever you do, don't involve OFTEC...

drill the bottom of the tank and put a pipe up as an internal overflow, then set the lot over a gully trap

what's wrong wth a normal spear bit for this?

squeeze and wiggle the spring and it should come off the legs it pivots on

check out Keylite also

why not just use as much lekky as you want, til something blows. How can they blame *you* if there are another couple of houses on the pole...

just put a spanner on the "nut" in the middle of the hinge, to try and jack it L-R?

or just done it live and got a bit wet...
