It's approx 12m, the job ain't finished so the Soil pipe is just sitting on the AJ.

So the soil pipe is higher than the inlet on the AJ(see pic). Was thinking of cutting hole in riser and sliding onto pipe but due to the moulding of AJ there are three flat spots with the bigger one obscured by the pipe. Would be afraid of waste falling and sticking on this. There is a 1/60 fall on soil pipe am afraid by fitting a bend further up soil pipe and connecting in at the inlet on the AJ that the water may leave the waste behind. Pipe run is right to left. Any ideas?

Thanks Nod, few tilers looked at it and said that i would need to get the heating up and running (which it now is) 1 deg a day for a few weeks and allow to cool for a week before tiling could commence, it's now set at 30 degrees and tbh will never be set that high again(21, maybe 22 if she gets her way). Floor is down since July 23. so it will be no harm to do the same thing again once the tiles are down, thanks again.

Hi, Starting @ 20deg temp (lowest setting)what's the max I need to hit to see if any cracks appear before shutting off to allow cool and tiling prep can start? Bear in mind it's 6 inches of concrete.

Water heated via ASHP, will get a reducing valve to be safe, thanks.

What purpose does the pressure reducing valve have? Will try the bucket tomorrow, thanks.

Checked tap(albeit a make shift one) at full bore that was reading 3.9bar though that was the middle of the day, will try it morning and evening too. Is it OK to plumb toilets handbasin etc direct from main?

Is a water storage tank essential, currently connected to mains and hope to drill a well before the year is out. Had initially planned for pumped tank in plant room but after checking the water pressure (3.9bar) just wondering if the tank is now needed. I know if the mains were disconnected you would have the storage tank bit that wouldn't last pissin time in our house. Any ideas?

The top layer of steel looks awfully close to the surface compared to ours

Thanks James, will check with spark when he's back in January and plan to reroute the cables

Had to look up derating cables, actually the mains cable 25sq is running through and cables for the ASHP. Spark said not bout derating these, is this now an issue?

Made a bubu when running ducts, not enough space to run the two pipes in one duct including insulation so now may have to run either the flow or return in a duct that has cables. Would this be OK considering it'll one length no joins? Alternatively we'd have to to go through the walls which I'd rather avoid unless necessary.

Just looking at the heat geek page as I needed to interpret that table. Am a little smarter now than when I woke up, thanks John. So there is no need for the buffer as per table. Re the plumber, it's what i thought, but God knows how long we'll have to wait to get a new guy this time of year.

Thanks John. 9Kw. There is a buffer that came with the kit, though not sure if he'll be using it. If he is, it will be 9/10 m from the HP. Again 9/10m to cylinder from HP. I believe there's a pump on the unit whether or not that would be fit to drive the water around a 1900 odd bungalow I've no clue, Imagine another would be required if not?
