Wiring in room stat to my Potterton Netaheat Profile 40e

[diamondgas]

Great, so that means I can still control my HW by timer as per before and switch my CH off via the timer and just use the room stat?

Is the Honeywell DT92E wireless a good one?

I'd have to look it up to be honest but any honeywell is good in my opinion! Had no come backs and there a neat piece of kit 🙂

Well blow me!!! I'm carrying out illegal work 🙂 I thought Part P was for upto the fuse spur? So are you saying crOft that if i change a room stat or wire in a room stat, something I've done for 30yrs, I'm carrying this work out illegaly? Honestly that's the first I've heard!!

Hi mate,

I agree with what you are thinking, that it's mad, but it's definitely true if you are adding new control wiring for central heating (note, not replacing an existing stat if it uses the same wiring). It's the same principle as replacing an electric shower is fine but installing a new one is notifiable.

I only learnt this recently myself when I did my 17th Edition update course but it is clear as can be in this guide written by [DLMURL="http://www.lewes.gov.uk/Files/Plan_Part_P.pdf"]Lewes council[/DLMURL] (page 7 refers), there are various ones on t'internet but this is the first one I found on Google.

Haven't got my On Site Guide to hand at the moment but I'm pretty sure it's even clearer in there.

Your customers should be receiving a minor works certificate for a new installation I would suggest and possibly even a schedule of test results for insulation testing etc.

cheers for the replys guys 🙂

I could get an electrician in to do the work, but why would they sell these items in diy stores if you then need to call a specialist in to do it for you?

Someone must know which 3 wires I need to connect to the stat receiver from the timer control panel?

The same reasons that some plumbing merchants sell Band B boilers still. It's not illegal to sell you them (they are out to make money after all), only breaking the law if you fit them (in most cases). As I mentioned above, replacement of a room stat without modifying the wiring isn't illegal, but they do need to be notified if any central heating controls are added or you have to replace the wiring.

That's the theory of course, but the huge problem with Part P is people put 2 fingers up to it, so it doesn't really work lol. In my opinion there needs to be much better policing of it and far stricter fines.

I don't know how anyone will find out that you have done it mind you, but I'm just letting you know so you can make an informed decision, as you can see on here, there is a lot of confusion surrounding Part P.

Hi mate,

Not under part P if you are replacing but if you are installing a new room stat where there isn't one already then yes, definitely is notifiable. As are all central heating controls. I only learnt it doing my 17th Edition course recently but it is black and white in the Part P document.

Please don't shop me 🙂

Honestly sometimes I just have to sigh and wonder when will the madness end?

HoHummmm *shrug*

LOL I'm not going to shop you, not sure who would care to be honest! Was as much a surprise to me though when I found out. Having sold our house recently though and the previous one just 4 years earlier it was quite noticeable how much solicitors are catching on to the requirement for electrical certificates though. Our buyer's solicitor even insisted on a full periodic inspection report of our electrics. Had we had stuff that hadn't been notified like this we would have been caught out if the inspector was worth his salt.

If you are caught I believe the fine is £5,000 now though. To date the only people (that I'm aware of) have been fined have produced shoddy and/or dangerous work but eventually I would expect a building control department somewhere to make an example of someone somewhere.

I know it's not very helpful but my view is that we shouldn't be encouraging anyone to do DIY controlled electrical work, in the same way as we wouldn't encourage anyone to do DIY gas work. Both can be fatal if they are done wrongly.

*off soap box*

think that its going to catch on in scotland eventually also, at the moment we are still allowed to work after the spur and do cross bonding just not MEB

 

[diamondgas]

Well if I do something that fry's someone then i deserve the full weight of the law! If my experience is enough to merit compitence then so be it!

I'm at times now so glad i am approaching the twilight of my working life in this industry! The fears that be seem to be pressing down on folk and removing any realm of experience.... regards electrics there are so many circuit breakers these days I wonderif it is at all possible, however incompitent, to put some one at risk or danger?

 

[cr0ft]

Totally get where you are coming from. I've only been running my own business for 3 years so I haven't built up nearly the amount of experience you have. It must be pretty frustrating to be obviously competent in wiring in heating controls then Part P comes in and suddenly it's another course you have to go on and registration fees you have to pay just to do things legally.

Your experience is enough to register you with certain competent person's schemes by the way. Some like NICEIC need formal qualifications but some have far lower entrance requirements. Basically as long as you know your way around the latest edition of BS7671 and produce work that applies with it when they inspect you then you're in.

It's certainly a money spinner too. Most of the schemes are charging 2x as much as Gas Safe but they are providing (effectively) the same service.

It is as easy to kill people with dodgy electrical work as it is to kill people with dodgy gas work though. An under-protected cable starting a fire at night is going to be as dangerous as a ill-fitted flu leaking combustion products back into a house.

I'm one of the minority that thinks Part P is a good thing. It's not perfect and it will never stop cowboys from trading but a requirement to inspect and test new electrical installations can only make installs safer.

Total respect cr0ft 🙂

i grew up teaching sparky's how to wire heating systems (honestly, house wirers didn't have a clue!) and still smile sometimes when it comes down to it! However i am not privvy to the current electrical regs and undertand their importance in todays fear based society!

What will be will be eh? 🙂

 

[WHPES]

Doesn't bother me as I'm far too lazy to be bothered to work out wiring diagrams anyway and just get in my spark friend (who does likewise with me when he needs some plumbing bits doing).

Decided to take back the siemens stat and bought the Honeywell THR872 Wireless programable thermostat instead.

Wired in the receiver to my Potterton EP2001 CH switch.





Now the programable Thermostat is controlling the CH time/temp.

The HW tank still gets got when the CH is on which I guess is good?
