looks like we crossed... Check it's plugged in and free to rotate, and that there are no anti-frost protections in play.

are both fans actually running?

yes, less restriction means less fan power to get the required flow

Any chance N and E are reversed at the source?

A high resistance on neutral might do it (as there's always *some* leakage current to earth) but it does sound like it's the RCD. but whenever you *do* get the RCD to latch in and the lighting MCB trips it that does allude to a problem with that circuit. Is there an extractor fan in the loo perhaps? Where is the power coming from for the van? What kind of cable? Is there an earth rod?

why do people need so many clothes?

^ this, although the Peak/ Lailey&Coates units do indeed come in British Racing Green.

you bad man.

Our pipe down the lane from the Toby is just about a kilometre. The 32mm is well deserved here...

yes, but there are only two wires and you can adapt or extend as you require, just pay attention to the polarity

it's just two wires though.

I wonder if being powered ON all the time will actually slow response tho- even with no flow or energy input aren't they going to close down to try and maintain a deltaT? How will they then respond to a very slow rise in supply temp?

I've recently bought a Cool Energy 9.5kW unit and it was easy to instal and has a pretty intuitive controller. Temperatures can be set freely for heating or cooling...

but when did folk become so combative and thoughtless? Didn't seem to be an issue when *everyone* lived in rented terraces with outside loos... and don't presume everyone in the countryside is neighbourly.

^ yep more of the green or reddish-brown algae over here it seems.

what kind of "sound insulation" is it presumed to be?

I dealt with World Heat, very accommodating.

And caution here, some of the cheaper mirrors don't have an isolating transformer for the shaver socket...

jeez that's a monster for your wee bungalow... jet's either 0.75 or 1.0 but that's quoted at a standard pressure, so the actual recommended pressure varies.

nope.

1 vs 2 ducts is more about flow restriction/noise/ duct length than room size.

your jet will be something like .55 USgal/hr and it's a one pipe system so that all the flow you need. No, a car one doesn't really do it. Your really looking at the balance between CO2 and O2 in the flue gas (it needs to be pretty badly rich before the CO starts rising in my experience) there's a kind of a knee-point in both of the gasses and you can balance them looking at flue gas temperature too. Minimum excess O2 that keeps the CO2 at specced levels, with no CO and minimum flue temps. Easy.

did oil run out when you broke the oil line at the pump? Yes? firevalve is OK.

there are other suppliers of very similar bespoke units that *will* deal direct, too.
