does it need true isolation or just switching, and how often? An SSR might fit the bill.

the grille at the back I'm pretty sure is only chromed, mine went a bit brown but when rubbed off it settled down. The corner, it might be worth giving it a rub with scotchbrite just in case the wrong wheel was used when buffing it?

any chance the top bars are fake, with no flow through? also, have you bled *both* sides at the top?

Real men braze their gas pipelines...

how tall are the walls?

if their line was suddenly faulty and needed replaced????

not that any developer would care, but how much extra insulation thickness do you need to counteract the cold air under the suspended floor?

I've seen those Wylex RCDs do odd things before.

night mode is likely to mean reduced output rather then any less efficiency.

How handy are you with a multimeter? Unplugging (say) the fans and the compressor and re-trying could be a start but lookiing at that trip, I might start there.

It's more about the DeltaT tho isn't it?

ours does an aerate-settle-pump out cycle, the air pump is off quite a bit of the time

On mine (which is built on a standard Carel platform as used in retail fridges etc) the fan, compressor, expansion valves etc are all under constant control, and the characteristics of the compressor and gas are programmed into it. I've no doubt there's some map in it that you could alter to improve things at the frost-point (or maybe it already does it, dunno)

complex to implement as you're already at the whim of the inverter with all it's sensors and lookup tables.

No they absolutely do frost up enough (in our microclimate for sure) and the difference between a light frosting and solid blocking ice is less than ten minutes of operation.

On mine, the fan speed ramps up noticeably as frosting occurs- from 85% in "normal" full power operation to 100% when it's blocked up. But the defrost actually happens on a time and temperature basis. Based on @J1mbo's calculations re 24h operation I think I'll play at reducing what setback I've currently got programmed...

I'm wondering if this might be some of the differences that @Hogboon has seen in rise time. I'm certainly looking very closely at setpoint vs defrosts currently- threre's lots of time with a misty ambient 2-4C locally...

can you factor in occasions of defrost cycling?

@Conor a bit past Bloody Bridge, well before the Quarter Road. (a mate has a cottage up on Head Road...)

hello there... is that Annalong direction?

Loftboxes are great, as they can deal with high and low levels, and feed masthead amps etc

Each UFH manifold has it's own mixing valve, use one for the towel rails... that's exactly how I'm running my towel rails.

once a month? How many litres is that?

but what is the *rule*? There's lots of opinion but nothing definite...

Why?
