Baz1968 thanks for your time and advice , plumber coming Monday fingers crossed, should be able to give him a nice schematic to work to now although he said i've got to run all the cables !!! Cheers

Great stuff, does the link still go in from L to terminal 2 at the RX1 receiver unit ? If it does and you have the patience could you explain why . Thanks

BAZ1968 Sorry ran out of room and couldn't work out how to change text colour so my replies are same colour at the end of each of your questions. Hope it makes sense.Thanks

Only unsure of that stat connection really [

Finally got it down as I now see it, is this what you meant BAZ1968?? If so is there any issue with bulking up the demand wires in the Wiring Centre as it's done either here or at the boiler position I suppose. Your comments most welcome.[/img]

Baz1968 that is a very clear concise answer , thank you. I will need to draw this up to get it clear in my head as a logical procession and if o.k with you post the drawing to see if I have got it straight? Thanks again

Thanks for reply but still not clear, the boiler is as you say fed by a switched fused unit. However the wiring centre for the UFH is shown as having it's own supply via the programmer which in turn is fed by a separate switched fused unit. So the demand comes from externally . Does that make...

Hello hope someone can clarify for me. Have a Worcester 30 CDi combi , am installing a UFH system and a separate zone for the remaining rads. Both zones will have wiring centres and these both have a demand cable going to the boiler with switched Live, N and E . The ST10 connector in the...

Thanks for prompt replies, I have a TN-S supply, Type B 32A MCB would be installed. May not put in furthest socket to give myself some slack.

Hello, in my new extension being built with a floor areea approx 46 sq metres.I was going to install a new 2.5 mm ring main and the LABC will inspect and test it. My problem is that doing the measuring although the sq.meterage is only 46 the cable run will end up as nearly 80 metres due to the...

Hello all, I need to affix some 19x38 battens to the sides of my ground floor suspended floor joists to put celotex on for my new extension. As these fixings will be under the new floor in the ventilated area should I be using galvanised nails or screws or will any old nails or screws do for the...

Thanks WYL for your time and advice much appreciated, I 'm sure i'll be back on before long..

I see that the recommeneded joist gap is 30-35 cm I have 40 cm. Will this cause a problem do you think?Thanks

Thanks WYL, the "screed" is only 25-35mm thick on celotex type insulation so isn't really structural. If installed as floating why would it need a DPM?Would the sound insulation start to affect the UFH 's output?With this in mind I would like to install the floor straight on to joist to...

thanks for replies, WYL have looked at the site v.good info still a bit lost on whether engineered wood can span those joist c to c's and if they are t+g'd all 4 sides can the joints be between joists?and if they can be laid straight on to joists without an intermediate layer.?However the wider...

evening, we are thinking of having a solid hardwood floor(oak) over our proposed new UFH which is between joist with a dry mix covering the pipes up to the top of the joists.The joist c-to-c are 400 mm.The UFH supplier and wood flooring suppliers are a bit vague about the following ..Can the...

Thanks Chrishutt that's fine you knew now I do , cheers for that I shall be solvent welding like a banshee tomorrow with my mixed bag of fittings/pipe. When will the BS go and the EN become commonplace ? The sooner the better for us ignorant ones !

Chrishutt, I may be playing the ignorant card here but is EN the European something that is compatible with the BS thingymajigg????I am being serious btw

Expertboy yes they do fit snugly, Chrishutt the BS no's however are different on the ABS (Marley)I have BS EN 1455 on the (Hunter) MUPVC I have BS 5255 which I believe is the compatible BS no.with other manufacturers. I suppose the question is that yes they both have the same outside diameter...

Good evening, I have purchased ABS waste pipe and some ABS fittings but also have also bought inadvertently from another place some MUPVC fittings, can these be solvent welded together or do I need MUPVC pipe for the MUPVC fittings and ABS pipe for the ABS fittings?The solvent cement i have says...
