it does mean that the control gear (switches etc) are more expensive and bigger for a given number of Amps than their AC equivalent.

check the strainer for crap.

jaysus the place isn't ready for that!

So where are we now then? Selfbuild insurance arranged and in place. First delivery of materials arrived- twenty lengths of 160mm perforated twinwall, and a shiny new gate. The swing off the lane and into the drive is just a bit *too* tight so some fences will need massaging a touch. Any burnable scrub is torched. New gate is on. We're ready for the digger to be let loose next week!

@Dudda is in the RoI so the rules are a touch different, wiring can be a little more "continental"...

just spotted this, another header tank option maybe? https://www.bes.co.uk/safety-valve-solar-fluid-recovery-container

just scanned through my TF quotes and 75% of them include external panels of fully treated timber.

Dave makes good points re. the loop impedance and I'd be querying of the DNO what their tolerances are if a mere 4kW is enough to push the supply ABOVE spec. Considering that both you and your neighbour will be on (eg) 80A fuses, so 18kW each... NIE for example quote 230v, but -6% and +10%.

go for the correct gain group rather than a wideband one.

bought maybe, but what about erected and certified?

Old expansion bottle out of a car?

Strangford and Lecale is certainly an AONB.

the protection is generally in the battery.

the ASHP will have ambient temperature sensing for defrost control; how many people set it up for their own locality?

Smoothbore (twinwall) pipe has less desire to silt up than coilpipe, anecdotally.

I'm looking at that spec and thinking it's about 50k too dear?

We trawled the many "book plans" sites over here and when we found one that we quite liked, the designing Architect modified it (quite radically, an almost complete redraw) to our brief. Various TF companies then quoted against that.

Soft foam everywhere. Set the pump on foam, line the housing, sleeve the airhoses if they're near/touching anything.

and just to confuse further, "inverter" HPs are internally 3PH but at variable frequency.

Rather than a steamer (high power consumption) try an ultrasonic unit. Maplin used to do them for fog over water features but you can get standalone too. See for example: https://www.ebay.co.uk/itm/1-3L-Ultrasonic-Humidifier-Air-Room-Diffuser-Steam-Purifier-With-7-Color-Light/142721319238?hash=item213ada8146:g:TdAAAOSwk4tapWRz https://www.ebay.co.uk/itm/DC-24V-Ultrasonic-Mist-Maker-Fogger-Humidifier-Water-Fountain-Pond-with/253483323394?epid=2076907171&hash=item3b04c89002:g:yRoAAOSwKvJapXmu

Well my particular examples are absolutely silent, even with the driver sitting against the radio in the kitchen that is bothered by our current MR16s.

^ agree with Nick. Ordered some 6W variants to appraise and they're stunningly good. Even, glare-free light. Dunno about anyone else but as they're alloy body and steel backplate I'm happy to accept them as fire-rated too.

Does anyone have experience or opinion on these units? Smart-looking controller and the MIs read well, but are they worth a punt? VIGO 550.pdf

Traumatise the wildlife? Definitely! Well, if we want to, all the windows *are* openers...

So the official confirmation letter arrived yesterday. Planning conditions are few, and simple, and just as per the Officer's report: Start within five years Obscured glass for the bathrooms Landscaping following completion Access works pre-commencement (yup, like already eight years ago) No conditions re levels or ridge height is a bonus. Digger man and his mate called on Tuesday and we've a plan of attack. A couple of land drains to put in (one new, along the short E boundary with the nighbour's garden and one to culvert the long open drain on the South. Then strip and retain topsoil and put down crushed reclaim over the drive and form clean hardstanding. Still waiting a revised price for the TF...
