In the picture with the garage door, where exactly *is* the boundary and has this been confirmed by a mapper?

the insulation was just as a soft packer to ensure the slab was clear of the wall.

ours sits on the back step and I slipped a strip of inch EPS along the wall before the guys poured, for isolation.

we run a TS but with the heat pump on a coil (so no massive amount of glycol needed). I've it configured to have all CH flow passing through the coil as a buffer, and the tank heated farther during the DHW times. The CH can therefore run off diverted heat from the PV as well as from the boiler stove which is plumbed direct to the TS. My observation is that you can slurp heat out of the bottom coil of the tank quick enough that the bottom of the tank goes cold. Are you sure your scheme won't suffer from stratification and not actually hold as much heat as you anticipate?

I think I just uninstalled, cleared registry entries, and put it back on again?

next would be to check the connections between the mainboard and the internal display, I'd guess. Power off first! and if you can isolate the internal and reconnect the remote one, that'd be next (sorry it's a while since I've had ours apart and don't recall how the front display and mainboard connect)

disconnect the wired controller at the local end, and see if the unit then works.

I was very happy with the terms we got from the small-ish TF co we dealt with. 30% deposit 10% on completion of design, to release structural drawings to BC balance on completion of erected structure with an offer from the Co to withhold an amount to cover any missing or snagged portions

surely tho you'd need two pumps else the risk is the same?

plenty of oil in the sump? In the tank?

I've been doing a bit of searching. and gleaned that the diverter in this thread is indeed the same as the CoolEnergy one, and if anyone wants to deal direct with the chinaman you can have one from the manufacturer direct. I'll not post a link but you'll find it on Aliexpress from "Runhu" and it'll cost you about £140 including shipping and vat. photo of internals The fan is a bit bigger than the iBoost's by the looks of it, and the general build is so similar that I'd opine they could be the OEM for it too, lol

supply and extract being *exactly* the same on boost certainly doesn't pass my sniff test. Airflow is a pain in the a*se to measure and set up...

where does the lift plant go?

give ATS a call too

check the status of your local exchange- some are already closed for new copper connections and FTTP is the *only* possibility.

got one, good job.

is the requirement for a treatment plant log book- and ongoing sampling- not a German/ mainland European thing?

was it Boris?

sounds like they've accidentally included hire, at those costs...

aren't they the really sappy b*ggers that aren't recommended in a stove?

it's up to the fabricator to remember to insert the steel sections with any profile, I fear.

eh?

I'm using a 9kW ASHP on a smallish thermal store, so we don't have a massive amount of *stored* energy until there's plenty of PV diverted to it. Nevertheless, the tank never runs cold and the heat pump will cut in and recover seamlessly. Less than an hour will recover the tank.

@crispy_wafer what size Solido is it? I've just checked our documentation and the 6-8PE is 150kg, needing a 180cm dig, it's got a lifting eye on top and no concrete required... best practice is to steadily fill with water as you backfill, to equalise the loading although the moulded tank can take full load either way unsupported
