the critical Q. as @TerryE says is what size of digger and dumper are you wanting to drive through? Is the garage door and it's lintel being removed?

Is that not a blue turny bit at the bottom of the photo?

Superlec blow my local factors out of the water.

Diesels run un-throttled and have a much higher compression ratio, too...

Fibre. Our man swears by it...

spot all the English that can't tell someone's religion from whether they say "aitch" or "haitch"

yep, not so much a UK thing, that one?

the Aico is combined heat and CO...

Radon polythene is 100% virgin as I recall.

A settling period is good, but only if the aerator has the oomf to break through settled sludge on re-start. 5mins in the hour does sound *very* short however...

According to the website: "3. The final settlement tank is where the excess biomass settles to form sludge. At preset intervals, portions of the sludge and liquor are returned to the primary tank for additional treatment." however excess implies there was "too much" in the previous stage chamber. Why would it need to be sent back for additional treatment unless somehow harmful to the outflow? I'd be going back to Kingspan for a WRITTEN response on this as if SEPA got wind of a non-compliant install someone could be in a world of pain...

If a solenoid is required for the install, it should have been supplied along with the plant. Are the unit's efficiency numbers quoted with or without said valve?

Is it not 1.46 that applies in this situation?

except you won't, because it'll turn itself off...

For anyone looking some IP65 LED battens, these are a super buy. Good brand, light's a nice colour and the added microwave sensor is worth the price they're charging on it's own. I bought 5 and there's plenty more... https://www.ebay.co.uk/itm/384763287555

...and remember that holes in steels need to be positioned wrt the pozijoists too so there could be a to-and-fro between the pozi designer and the SE (if they're different people) I just asked our TF guys to design in a couple of holes in each steel and had no problems routing the services from that point on.

screed can be gypsum too if you prefer

^ that's just a tripler from an old telly.

I've just been through this for my own big shed, and ended up getting some bays of used longspan which gives loads of space. 2.5m bays.

screwless faceplate, or screwless terminals?

it wouldn't take long with a masonry bit to confirm or deny your suspicions

£100 for a one-off fill of glycol vs (say) coming back to a cold *and unheatable* house after a nice skiing holiday, because you'd turned the heating off and there was sudden cold snap? No-brainer for me, and I don't even do skiing...

anybody got a note on how they're supposed to work?

filters can be a ripoff. The media is cheap- look at the average car spraybooth, the non-woven media used is about £2/ m2. But cut it into a wee piece for (say) a fume hood or even an MVHR and well...
