Thanks for the response, do you think I'll feel a diffeerence between the insulation method or not? I'd prefer to glue to screed but not sure if 25mm insulatiuon will make a huge difference. Thoughts? I assume the sika primer levels and creates a moisture barrier, will this be adequate...

Hi all, I'm having an extension built (6m x 7m) and installing wet UFH. The architect has specified the floor construction from ground up as 1, scalping oversite 2, DPM 3, 100mm celotex 4, 100mm concrete 5, 75mm screed The UFH pipes will be clipped to the 100mm concrete prior to...

Hi all, I'm planning to fit walnut floor on my ground floor of my house. The existing screed (30mm) is uneven so will be taking up back to the concrete oversite. There is no damp proof membrane other than bitumen painted onto the concrete oversite before the screed was laid. I cant raise...

Anyone?

Hi, Ive done a quick drawing of the location of the oil tank. My point is that the existing tank is in worse condition and more likely to fail than a new single skin tank. The green line id the boundry of my garden, drawing is to scale in mm. I havent shown the neighbours house but it is...

Hi all, plan to change my metal tank for a single skin tank Ive read the oftec rules but have a couple of questions. 1 - When it mentions controlled water, what is it referring to? water main? drainage? 2 - The neighbour has a well in his garden which is about 30m away, the regs state a...

thats excellent. do you think its worth the bother making my own control station up or buying a factory one? Its for 1 room of 6 x 6 only so seems expensive, may be worth the outlay for a whole house but for 1 room? Thanks

thanks, obviously I now have more questions. [Yes you can make them up separate] What would be the components I need and what order do they connect in? [If your room thermostat switches the boiler off then the uf section may not be up to temperature. (assuming it does not have a...

No reset on old one but the tank and rest of system (i've had no boiler since we've moved in september) is comming out for building works and replaced with entire new system in the next couple of months, so I'll live without reset for now. New one had reset but was mangled and couldnt reset...

thanks all, I know cutting beams and notching is best avoided, I just thought someone may have a cunning plan. I've looked at it more and I can run the pipe parallel with the joist and then down the outsde of the house (which I was trying to avoid) but will have to install an extension to...

Hi all, you help is needed. Call me stupid if I'm missing something obvious. Regarding underfloor heating pump and blending assemblies. I have a few questions. I'm replacing my entire sytem with grant oil boiler and pressurised indirect solar cylinder, there will be mainly radiators but...

update, immersion working fine but cheap and nasty thermostat (from toolstation) stopped working 3 days later. Luckily the thermostat which was used with the damaged element was working fine (after 20 years, dont make em like they used to) so I replaced with this one. Sorted. thanks

Thanks, appreciate the notching theory but how can you achieve a fall in the pipe if you can only notch? Rgds

Hi all, usual question but I have no alternatives. I'm having a loft conversion and have a shower enclosure to install. I can run the waste paralell with joists but need to go 90 deg across about 3-4 joists. The tray has to sit on the floor as I have not enough head height, so no...

I didnt check the breaker, perhaps thats why it wasnt working..... :wink: Joking, fully earthed, no tripped breaker and voltage/current flow ok. Yeah, it does seem suprising but as the water was getting luke warm only I can only guess that the element did not short to earth and the current...

Replaced the faulty element now . It was wrecked, 6 splits in it see pics :shock: . It was a bugger to remove, had to tap union with a hammer to free up and then tap the box spanner. Thought it wasnt going to shift but it started to move :D , just had to ease left to right until...
