Sounds like you need to get the guy back in to have a look and get in touch with hetas if you're not happy with his explanation. I'm surprised he agreed to install it onto wet concrete or did he lay the concrete base himself?
Morning Stephen, floor area is 2m x 3.5m but the space is quite small, 2m at the apex sloping down about 45 degrees so it's not a big volume to keep warm providing I do a good job with the insulation.
Hope this explains. In the junction should be four terminals.
Join the neutral from the feed and the neutral to the light in one terminal.
Join the earth from the feed to the light and the switch in one terminal.
Join the live from the feed and the live to the switch in one terminal.

It's your house so go for it. I can't see timber giving any less support than breeze blocks and if your roof caves in just plead ignorance to the insurance company and say the timber supports have allways been there.
You could use roofing felt over the pallets and hardboard. A £30 roll will easily cover a few pallets and it would make a good waterproof astroturf substitute.
I'm sorry, I can't help with the 40mm waste as I'm not sure exactly where you're trying to connect it to. If it's into a bigger pipe then get a 40mm hole saw, cut a hole, push the pipe in and seal around it.
The collar might come out in one piece but if you have to smash it and bits go down the...
I fitted a new bathroom at my parent's last year and had the same problem with the old toilet. Modern ones sit much closer to the wall. I removed the clay collar and fitted the new toilet with a flexible 6" waste pipe from one of the big diy stores. I guess the only alternative is to knock...
It makes sense to use something that's designed for the job. Next chance I get I'll have a measure up and see how much I need but I guess I'll have to get a proper valve if I use the polypipe.
Where can I get UFH pipe from? I've seen it as part of a kit but not on it's own. I guess if it's specifically for UFH then it radiates the heat as well as copper pipe and 15mm would definitely be easier on the pump than 10mm. The loft is well insulated and I'm going to cut some notches in the...
I think I'll put in a radiator valve just in case it gets too warm. I'm using the 200 year old floorboards that were originally in the bedrooms so I think they've seen enough to withstand the heat. I was thinking of using 10mm copper pipe so I can bend it round and not need any 90's. I'm not...
Thanks again for the advice. I'm planning on using copper pipe under the floorboards rather than the pex or pert types which is why I'm questioning the use of a control valve.
Do you think this will work? In the bedrooms you can feel the warmth of the CH pipes coming up through the floor...
Fair enough. If I need a valve to stop the pipes from overheating then what protects the rest of the pipes in my CH system?
As far as the loft goes, would a radiator valve (TRV?) do the job?
I'm no builder but I did a similiar thing ten years ago and I've had no problems. I took the chimney breast out up to the loft, fixed a piece of chquer plate to the rafters and bricked down to that. Because we use the fireplace in the living room and they conjoin like yours do I had it flued and...
