yes. boiler stats tend to have quite a wide hysteresis so if it's clicked off, the water could need to drop 5-15C before the boiler will cut in again

will the microinverters play nice with the gennie or will their smoke leak out?

ours has been off for a number of hours (3-12) three times since we got the mains connected.

Surely the boiler stat has the veto here?

I note that the comments negating the likelihood of outages *aren't* coming from folk that live out in the sticks where power is HV *and* LV overhead...

I've a number of Hoymiles microinverters and the required wifi bridge. Setting up the account was a bit of a faff (as I was the "installer" as well as the "user") but the App itself is great, I really can't ccmplain.

why is the RHI so important?

Something must've changed over the years- 3-bar electric fires and various other 3kW heaters also used to work off a plug just fine back in the day, but nowadays a 2.5kW tumbledryer overheat a plug. And don't start me on 3kW elements in Water stills that run all day long, on a 13A plug...

@Nickfromwales why would it be Solaredge if he's got Tigo smart panels?

I'm intrigued by the other unnecessary gizmo in the loft- was it a WIFI bridge for monitoring? With some systems it's a mandatory requirement for G9x compliance... You still haven't told us what inverter you have.

continuously lit or PIR? There are chinesium solar floods that can be wall or pole mounted, I've one of these on the corner of the house and it's very impressive https://www.ebay.co.uk/itm/233670054949

It definitely has a moving part, and... how can the COP be greater than 1?

can someone educate me what "this kind of interior" is please?

@vala you might try doing both tbh.

so they should be cheaper as their own brand then

never heard of them.

try it on 2...

it's more a groundworker thing than a plumber thing, if you ask me

That reads very expensive...

was it a cheapie? Keep it...

@vala yes. But what is the pump set to/ can you turn it down a speed?

PRV will control dynamic pressure at it's point of fitment. The softener's restriction is dynamic, not static. So static pressure will be the same for all past the PRV yes, but once there is flow then you'll lose some part of that 0.5 bar everywhere after the softener

as wonderful as the Salus jobbies are, perhaps they struggle at the small openings required if there are no other flow restrictions, the stepper will only have a certain resolution. Doing a "rough" balance with the flow meters (and maybe turning the pump down a bit?) should let the actuator work over more of it's span.

"6 mins each" No, it doesn't work like that...

Is the aquapanel actually needed in this situation?
