the silica gel should sort that out in the next few heating/ cooling cycles.

Our TF guys get their pozis from ATS Trusses

I'd caution against taking too much of what is in the Aquafix videos as gospel in the case of our domestic units, as they focus rather a lot on anaerobic systems and the whole point of air-blower plants is in adding oxygen...

worth considering UPVC vs timber too...

that's two independent fans back-to-back isn't it? And both are free to rotate? Might you have disturbed or damaged the temperature sensor?

If you're going through the wall and want to retain airtightness you want a https://www.schiedel.com/uk/products/additional-ranges/ignis-protect/

pretty sure any of the fittings with a male on them have built-in reinforcement

On a whim I filled that form in at the end of the week, and a blokey phoned today and will be calling tomorrow. Watch this space...

^ yep. We used Ignis Protect to go through the walls in an airtight manner.

can we see these please?

How many amps is an IEC plug rated for continuous?

It's not "above" if it's inside and not exposed to UV

Bog-standard Apeer composite door here, confirmed as being 0.94

Yep, the Carel controller on the CoolEnergy unit can do this too- four programmable time/ temp steps, for heating, cooling, and DHW at each step.

What is your motive for asking tho? Are you trying to second-guess a prospective contractor's own pricing structure, or thinking about going self-employed yourself?

For now, BT still cling onto the old geographic rules. One of the reasons I went 4g was that with VOIP I could retain the number, whereas BT refused to let the number even move between sub-exchanges in the same main exchange group. Irony is, now that the number is ported to voip, it could in the future be ported back to BT *anywhere* in the UK...

openreach no longer offer copper at either of our local exchanges and fibre is looked after by a 3rd party who hasn't completely trunked our road yet. Plus, fibre installs are subsidised under Project Stratum but the area was surveyed prior to our build So 4g it is, for us. the router and voip box are both on UPS, and my old landline number is now safely transferred to VOIP and in my ownership

flow gauges act as a coarse NRV do they not?

I've got a couple of Tapo cameras and they've got an rtsp livestream that you could pipe into another recorder/server; I just monitor it on a couple of windows in VLC. Is the same possible with these brands?

NTC sensor + 8m of cable = profit. / in other words, just extend the cable...

why not tho? Seemed like a no-brainer as the wiring was going past a zero-volt relay contact... /if it does ever go off at least I know the emptied property is being purged.

@JohnMo I never said anything about staying in the house...

On the fire/ smoke side of things, will the Aicos all be wired interlinked or will you be having any on wireless? Do you have any need for CO monitoring? gas hob/ woodburner/ whatever? Whilst we're on wireless, I've used an Ei414 fire alarm interface for two functions- MVHR off during fire alerts MVHR boost during CO alerts.

the temperature calibration will alter a wee bit, but as the cylinder isn't running too hot and there's no big current being switched there's no safety implication IMHO

^ to avoid any ambiguity, @Conor has a sensor in the buffer that was supplied with the ASHP, some brands don't have this option. I'd suggest if you want to have a thermostat on the buffer, simply putting it in series with the demand signal from the wiring centre might work for your case? If either heat demand or buffer are satisfied the the ASHP will be commanded off, and it'll only come back on again if you still need more heat *and* the buffer has cooled.
