We're fitting underfloor heating to an existing mid '80's house. Turns out that there is only 10mm polystyrene above the block and beam :( Any idea on how to insulate this, and fit UFH, without having to raise the floor level significantly? Thanks

Interesting read. We're looking at an extension with UFH. Sounds to me like the golden rule is to be totally sure of the moisture levels before thinking about laying flooring. Also interested to know if dehumidifiers should or shouldn't be used to help aid removing moisture. Can they help...

I've got a question about framing the walls of a garden room. I'm just sussing out how I'd go about doing the framing. Here's my basic design I'm playing around with, which is an odd shape due to garden (no idea how I'll do the roof yet): From what I understand, the 400mm vs 16" question just...

I'm designing a garden office/gym at the moment. The base will be a concrete slab, insulated from below. Construction will be (from top to bottom) Around two courses of brick for the timber sole plate to sit on. 100mm concrete, top of which is ground level. 100mm insulation 25-50mm sand...

I've got zero flow at the shower with the pump powered off, and the temperature set to hot, OR cold. Should the pump let water through even when switched off? The pump filters are clean.....no air vents on it. I've not looked at the shower itself. It's essentially this type:

My shower has recently stopped turning on. It slowly got worse and worse... taking longer for the pump to kick in then would only kick in whilst fully on cold and now just doesn't start at all :( I've disconnected the hot feed into the pump, and essentially there's just a slow trickle out of...

It is "should" or "must", according to the regulations I wonder though? I wouldn't do that myself, as a complete novice with electrics. I would not expect to enter a brand new build house and find that - are they allowed to do that?

Hmmm...surprising. I just thought sinks...leaks...plug sockets...not a good mix.

Bah... Double post on a mobile... How do I delete this one..... Panic.....

Is this even allowed? Under sink is a socket. Here's the back of it. Is a socket in sink unit allowed? If so, is that wiring legit? Doesn't looked fixed very well either.

IGNORE...how do you delete threads!! ************ Moderator's note You can't I can Click on "report" and type a request with reason *************

yeah, it's step 2 I'm failing on. I thought the thermostat's wires went into the junction box in the airing cupboard, but having tested all those for a circuit, I'm now thinking that they must go to the controller under the boiler in the kitchen. I'll have to get the multimeter out again this...

We use both methods to be honest, it's a good point. :)

why would that be? so you can confirm the alarm set successfully? I think it gives us a green light on the remote fob.... I'll double check.

Cool, thanks :)

Ok, that's great, thanks a lot! Got in there and set the volumes successfully :) Do you also know if it's possible to change the volume of the confirmation beeps, when Setting the via the remote fob?

Can anyone supply me with instructions on how to lower the entry/exit volume that comes out of the main panel when entering/exiting? It's currently deafening levels, and there's no way you could come back late at night without waking up the already sleeping household. I've got the engineers...

No, I didn't - the old thermostat is still on the wall :( I removed the thermostat off the wall, connected the yellow and red wires together temporarily, and then tested various red and yellow wires in the junction box for a circuit - no joy. At that point, I gave up. I recommend you try the...

Heating system wiring diagram by gsf600y posted 3 Jun 2017 at 12:15 PM I've created a diagram of the wiring in the airing cupboard. Can anyone help me work out how to correctly disable the wall thermostat? Should I just disconnect all it's cables in the choc-block, and the move the white cable...
