Hi Guys I've searched the Wiki and faqs but can't find an answer to my dumb question (I'm a Sparky so go easy): I have an outbound heating pipe and a return heating pipe and they go all over the house. Each radiator is connected in parallel across these two pipes - except the last radiator in...

Hi Deanalewis The 715 is a timer (programmer). The 230 is a room thermostat. These are two different things (sorry if that obvious to you, perhaps I've not understood your question). Are you trying to fit the 230 onto the backplate of the 715? or; Are you trying to replace an...

Hi DrizzleSizzle Just remember when you're reading all those webpages - All electric heating is 100% efficient. Where else could the energy go? The important bit is what price are you paying for that energy. If you can cope with economy 7 (or the modern equivalent) then your heating costs...

It's "Y" plan right? A mid-position valve. So to get space heating you need a live on both the wire from the room stat (traditionally the white wire) and also from the "hot water off" on the programmer or the "satisfied" terminal on hte tank stat (traditionally grey wire). When both of...

Hang on a minute ... If the room stat is working correctly - that would have been my first guess but you have fitted a new one and the problem persists - then the problem must be in the zone valve. As you know in a conventional S plan the boiler and pump are called by the switch in the...

Is it just me? I love the idea of a "digital shower" :-) Laurie

Hi Simon As I said to the OP the information is widely available. As with most of these things there is no regulation saying "you have to keep up with the latest regs". There is something saying "you have to take all reasonable steps to ensure the safety of the tenants". Most people...

Hi Robertasparrow Your obligations (liability) is quite different as a landlord than those of an owner-occupier. Basically you have a responsibility to know what the latest regs are and to keep the property up to that standard. You don't need to take my word for it. You can google from...

Hi SparkyTris Think about what is happening in a gravity-fed hot water cylinder. The water comes into the primary coil from the boiler really hot. It then gives up it's heat to the secondary water in the cylinder and so cools down. It cools and gets more dense and falls downwards back...

I'm no expert but ... ; Surely if there is no power to the zone valve then it will remain closed and there will be no primary flow to the hot water cylinder. The obvious question is - does the hot water cylinder get hot? Laurie (why would she have a big electricity bill for an oil...

Hi Gary Just found the wiring diagram on the Drayton website "draytoncontrols.co.uk/documentation" As you say; link L to 1 output to stat in 3 return from stat into 4 switched live to boiler into 4 try that :-) Laurie

Hi Gary Yes :-) You said that the output of the timer was terminal 1 which went to the thermostat and the output of the stat went to 2 which was then the switched input to the boiler. And then you bypassed the timer by linking terminal 1 to permanent live. Remove that link and it sounds...

Zigg Listen to Oilhead. He got it right first time. If your 3-port valve has switched live/neutal/earth then it's a diverter and you need W plan wiring. If it has 3 switched live/neutral/earth then it's a mid-position and you need to change to "Y" plan wiring. Laurie

Thanks Ian that's what I feared. What would be the point of going to all the trouble of introducing a diverter valve if the programmer prevents you from separating the two functions. 2 channel programmer, Room stat and tank stat is surly the first step to improve the system. You need an...

I am NOT an expert (I'm an electrician not a Plumber). The more I think about this the more I think your assumption must be wrong. A few questions occur to me. If the tee at the outlet of the hot water tank served the radiators then what would have been the point of converting the tank to...

Ahhhh ... that's interesting. This set-up had a double pole switch and a bath/sink selector. It was wired so that the double pole switched the bath and the bath/sink switched the neutral from the double pole. I changed it so that it didn't switch the neutral but then couldn't see what to do...

Hi Guys I came across this immersion heater today. Can anyone point me towards a wiring diagram? top mounted elements, two elements, one long one shorter, only one thermostat, two cables incoming, separate switched elements. The bit that's got me puzzled is that one of the neutrals has been...

GU10 They will probably have been fitted with halogens but now is a good opportunity to buy LEDs Laurie

Hi all I'm a newbee studying for C&G2382 One thing I'm confused about is bathroom extractor fans. Is it true that they must be ELV? All the books I have say ELV but the wiring diagrams in the WIKI show mains voltage, and when you look in the catalogues what you see mostly is Class 2 LV. When...
