Hi all. I was looking into what size cable needed for a 9.5kwh shower and the general consensus is to use 10.0 Having read why with regards to voltage drop, is it mainly down to if the cable is insulated anywhere? (and the length of run) My set up will be from CU, under floorboard...

So yes your drawing is correct.............which brings me full circle as to why the new programmer will not straight sawp.........unless as mandate says the old backplate is naff

Hi Stem, I was aware that I could not have CH on its own. My initial problem is I have straight swapped the programmers and in theory it should work, but it isn't. I've done a new drawing tonight, hope it helps and makes sense.

Hi again Mandate, sorry for late reply had to put it on hold. No I did not change the backplate.....so that's a route to look down. Having looked again at my system I do not have a 3 port valve, only a 2 port valve. Hot water go's up into the HW cylinder and at the top of the coil there...

Hi Mandate, Yes that pretty much all makes sense...ish haha :) My programmer is a 2 channel one I though but then I doubt I have the correct stat. Would you be able to draw up your wiring diagram you have on your programmer hopefully I can see why mine does not work that way. thanks

Hi, I only think it is a y plan from some other post I have seen. I have 3 port valve pump tank and boiler. The cable labelled pump/valve I am not too sure where it goes yet, (i've not had chance to check) I've never tried to CH on its own, because I had always been told you could not...

Hi all, I wanted to replace my RWB2 with a horstmann s27r programmer. I am reasonably clever when it come to diagrams but I can not figure this out at all!. Currently on the RWB2 I have On the back of the RWB2 it shows the internals like this as per the...

Well currently the rainwater is around the side, I was going to move it to accom. the bath waste. But yes your right it may be more aesthetic.

Thanks for the info all, My dad did say about just runnign 32mm waste pipe down the wall and into bottle trap......but I think that will look really naff. It does seem that Hugh's 'bodge' is going to be the only way, unless I just drill a 32mm hole in the side of downpipe, stick waste...

Sorry yes, the rainwater pipe is standard size, I'm not sure why I stated 3 inch! (blonde moment) IS there a reason why this does not seem to exists? As I said in o/p I can not fit a standard hopper as the area it would foul the folding doors :(

Hi all, I'm sure they must exists but I'm dammed if I can find one to buy anywhere. I need to connect my bath waste to rainwater down pipe which is to a combined foul and surface water system. Where the waste exits the wall there is no rooom for a hopper head and need a strap boss or any...

Okay then gents. Don't tjonk i can be botjered to dig. may juat leave it aa it is

Yeah but like yoi say thays to bore a new hole. As I pull the old lead it will leave a hap for the new pipe to follow

even with something like this?

Hi all, After a couple of leaks on my lead supply mains I currently have 2 holes open on my property, 1. at end of my supply and 1 on the corner of my house. I have lead to plastic to lead to plastic (from a leak I presume before I moved in)back to lead and onto next house. (there is a new...

Well it seems they are responsiable from mains to stop tap at the footpath some 40m away :) So the pipe that is leaking is mine....well, mine and the other 5 homes it supplies but anyway it does beg the question when they felt they were allowed to keep the lead they took out :?: I am...

great info Geoff thanks. The cables I have are black thick cable from pole to house which is on a tensioner thing, then 2 cables go into 2 separate jellies and coming from them is a 2 wire tick grey cable running down the outside and into the house as per picture of first photo. So what...
