Gone West

Not completely. I have a SOLAR iBOOST which has two outputs, although the instructions say they are for two immersions, I don't know why one couldn't be used for electric UFH.

I just used a WorkMate with the jaws around 40mm apart and rotated the downpipe as I cut it with the hacksaw.

In the Lindab instructions they specifically say not to use power tools for cutting. The reason they give, is that using power tools destroys the galvanising around the cut. Apparently if hand tools are used then the galvanising is able to 'creep' back over the cut surface and maintain rust proofing. We didn't have any rust problems after six years.

I cut all our Lindab guttering system with a hacksaw as was recommended by Lindab.

@Daffy Fields & @Gingerbread welcome to the forum, both. Good luck with your projects, plenty of good advice on here. Keep us updated.

Yup, we're showing our age 😀.

Close the flow valve fully, counting the number of turns. Then open the valve half that number. Leave it a day and if the room temperature is still too hot, or not hot enough, adjust the valve accordingly.

We've just fitted some Cedral Click cladding which was readily available through our local builders merchants. They do a smooth or wood effect finish in a range of colours including timber. They have a featheredge (Lap) or T&G (Click) type. https://www.cedral.world/en-gb/cladding/

I used a Floplast double branched connector for back to back WC connections into a single outlet pipe. The outlet dropped down and the AAV was connected to the top. The BCO was interested in the connector but was quite happy that it was designed for that purpose. We lived there for over three years without any problems. https://www.floplast.co.uk/product/double-branch

We used timber studwork covered in 12mm Hardiebacker board in all our bathrooms.

That's interesting, our trims were steel and were screwed down and the membrane was welded to the trim.

The problem is, who does that? To ensure it is correct would mean educating the masses about WC, who don't want to be educated about 'boring stuff'. As has already been said, finding professionals who can do it is difficult enough.

I don't understand. The underlay used is a material that looks like a dark green nylon pot scourer and isn't visible in the last picture 😕.

IIRC the upstand is on top of the underlay.

These are the best I've got, sorry.
