just drill it, and go for a second option *if* the drill runs into something insurmountable. Like Peter's horizontal core...

That ladder hoist is very smart indeed. Noted for future reference...

foc? really?

so only 8kW then?

many bends? If you could replace an elbow on copper with a smooth sweep of plastic I'd say the slight difference in ID would be lost.

maybe he/she does...

is this professional work for profit? Did a SE design it?

Architect appears not to have considered this?

and how much shorter are the other runs? I'd put a second length in ...

just do two runs and be done with it.

the internal bore of the flexy is much less tho, and some are better than others. Those looks like JG ones, so the hose is only 13mm inside. Whilst eg BES item 13753 is compression, it's also 19mm bore, much better flow

the first one is common, it's to do with family fallouts and the possibility of denied access IIRC.

those flexys don't look terribly big bore?

So at the weekend we celebrated a year of PV generation. 2970kWh not so bad eh?

was it actually meant to be above- or below- and if below is it just an understair or an open room?

If the mat floats won't the tiles sound hollow then?

^ similar experience here, got free "non- dimmable" Aurora GU10s with a batch of downlights and found that they dimmed very well.

Been wondering about this myself, it seems counter-intuitive to me to have a thin layer flexibly isolated from the base.

and if you have scaff and need some up on it, now might be a good time...

going through our TF quotes, the extra cost to go from timber to posijoists was 2-3k, over 120m2. Spans all around 5m.

careful... by the the time you take off flashing kits and valleys it can be a fair bit smaller than anticipated. btdt.

so the irrelevant twisty bit unscrews and the self-tightening conical collet with the barbed teeth still holds firm? not seeing a problem there...

I went with a similar but cheaper option that controls right down to (IIRC) 25c and has an integrated bypass and inlet restrictor ( there's a more basic one without, bit using the same thermohead I think) https://www.amazon.co.uk/Universal-Underfloor-Heating-Thermostatic-without/dp/B076KK1KQF/ref=sr_1_119?dchild=1&keywords=underfloor+pump&qid=1594565525&sr=8-119

yes, tell us then.

...still waiting to hear about them undoing themselves...
