I've no interest in pursuing the guy but I have the original signed Declaration of Conformance and current contact details. I thought it was a grey area though falling between the sparks and RGI so no one individual was a fault.

Would the install be considered non-compliant? My understanding is that it's safe from a gas perspective but not conducive to a long lasting boiler!

It's not fitted asper manufactures instruction so it's not to currant standards, the issues are ones of controllability, efficiency and longevity of the boiler.

Is an RGI possibly incompetent to wire a full installation? just going by your post here?

There are RGIs who don't wish to have anything to do with wiring but It's dependant on the RGI, a lot of RGIs can easily wire a heating system as it's not rocket science but it generates a lot of grief on sites or jobs as some electricians don't like it, so I find most RGIs will let the sparks do it for a quite life.

I like the jobs where both trades learn from each other.

Definitely I am of the same thinking, bottom line is a non RGI cannot wire a gas boiler so how far does one go in wiring an installation to hand over to a RGI?
Would say an external joint box be a solution where the 2 trades marry their wiring? But saying that are we back to trusting the electricians wiring which may not be correct as we see in this case and as the RGI is the one signing off its his neck on the line.

I get to see a lot of installs and the successful ones are those where trades listen to each other irrespective of the job their doing.

I see no problem with sparks wiring boilers after a quick chit chat with the installer or if the RGI wants to wire it himself the sparks should be happy to leave the fusible switched spur under the boiler.

There is a lot of misuse with heating controls the worst being the position of the room stats, i'v seen them over rads, in bookcases, 7foot up the wall, by cookers, by the front door and my favourite over a toaster so no heating during breakfast, then you have the neutral of the room stat not being wired so you lose the anticipator which drives homeowners cracked .

There has to be a element of common sense in the approach to installs and that's where the importance of communication kicks in.

Definitely and one solution would be working drawings but alot of electricians are head strong and don't want to be told how an installation should be wired.
In my opinion since an non RGI cannot wire a gas boiler a RGI should be the sole person to wire an installation. Let the electrician wire the switch fuse outlet and leave the RGI off from there, that seems more pratical.

As a heating engineer I think only RGIs should be wiring heating systems:eek: not because i'v a inbuilt hatred for sparks but if one person does the job then over time you learn how the controls interact with each other and become better at designing a heating system that will get the best out of the plumbing and wiring.

As for working drawing, as you don't have W or Y plans here (I can't think of ever seeing a 3 port valve)and your only wiring S-plans, any sparks who doesn't know how to wire a S-plan shouldn't be going near heating wiring and the same goes for RGI's.

S-plans are simplistic, they are the backbone of heating systems here and the basic design has remained unchanged for over 40/50 years, as gas boilers have developed the flavour of install has changed but the base ingredients are the same, the MI will tell you what to do.

MI give full wiring instructions and there's always someone like me from the manufactures to happily explain how a particular boiler should be wired.

Let them at it, far to complex for electrical personnel.

Not really especially if the manual is looked at.

It would be silly to say sparks can't wire a heating system.

At the moment my boiler comes with the ability to run at two different temperatures, to do this you only have to wire the demand from the cylinder MV to a second link on the boiler and fit a outdoor sensor, the only trade wiring this is RGIs I don't know why plumber and spark teams choose not to do this and it could be well due to the plumber not wanting it, the customer would be better served if the advanced controllability was utilised.


This is yer working environment not mine, i come from a different environment so the differences stick out, that's not to say that there isn't a shed load of bad heating installions where I'm from.

I don't agree for the following reasons:

1) To qualify as an RGI according to this link "An RGI is an installer who has at least a GID (Gas Installer Domestic) qualification". According to this link a qualified plumber can obtain a GID qualification in just 10 days. This simply does not provide enough time to train a plumber a level that would be the equivalent to that of an electrician. I could see insurance companies having a field day with this if something went wrong:eek:

2) An RGI as a "competent person" would be permitted to carry out "minor electrical works" as defined by the Commission of Energy Regulation here. But wiring mains voltage heating controls such as throughout an installation including items such as stats, zone valves, a pump, boiler etc. cannot be defined as "minor works". Therefore by law this work must be carried out by a Registered Electrical Contractor.

3) Then there is the issue of testing. Take an example of controls wired in a house as per the diagram shown below. Again this is not "minor electrical work" so it should be tested and certified. This means using suitable calibrated test instruments, being familiar with ET101, knowing how to use the test instruments and being qualified to certify the installation. This can and should only be carried out by a qualified electrician.

4) Without a doubt there are badly wired heating controls throughout the country. There are a few bad apples including electricians, plumbers, registered gas installers etc. This does not mean that the best solution is to get plumbers that have passed a 10 day course to carry out electrical work that they can't certify. I mean that with no disrespect to plumbers or RGI's many of whom are very good at what they do.

What we need is:
● Better communication between trades.
● People reading manuals!
● If an RGI is taking responsibility for the electrical controls then he/she should ensure that the function correctly before signing off on them. If it does not function correctly do not sign off on it, simple as.
● In some cases some electricians need a short training course.

It takes 4 years to qualify as a plumber, does a plumber not get any education in electrical heating controls in a 4 year apprentice at all?

That drawing is incorrect as there are no neutrals to the room thermostats, thus no anticipators & therefore extremely inaccurate performance.

CER have also confirmed that heating control circuits fall under the category of Electrical Minor Works as long as there is no requirement to enter the fuse board/consumer unit, for example, there is sufficient or existing 10mm earth bonding and/or the circuit it is taken from is not at capacity for that circuit.
They are basing that as extending a circuit or utilising an existing circuit.

Regarding the 10 day course, GID is no longer available or on its last legs.
It is being replaced by an 18 day course. You must also consider that they are not 18 day courses but 9 week courses where they receive 2 days per week training but they "should" spend the rest of the week studying, revising & preparing with home study papers & questionnaires.
Competent means suitably trained, qualified & EXPERIENCED, therefore if the RGI is all of these, then he is competent. Coming out of a 10 day course, he will not be competent in wiring a heating system, but equally he is not be, in the eyes of the courts, competent to work on a gas installation unsupervised.

I have no argument with the above(apart from the bit you put in bold:))

Heating wiring is something I take great interest in as I inspect a awful lot of heating installs under the boilers warranty and have done for 10 years in Ireland.

Very few heating systems are fitted as I would want in my home, home owners spend a lot of money having heating installed and as professionals we should give them the best install for their money, when the job is done right then the system works well and there's no drama but when it's wrong I have to report it leaving the customer concerned about their expensive investment and me with a headache.

Heating installs in general are bad so looking to improve the overall accountability has to be talked about.

Below is the syllabus for the course plumbers sit to wire there own heating systems in the UK and having done my Part P I have a better insight in to what it is ye do, it's just a shame I'm to fat for the Snickers they do look cool:cool:

So with the correct training RGIs could become heating engineers:eek:


PartP syllabus: Domestic Electrical Installer (Part P) training covers the 17th Edition Wiring Regulations, plus the following modules:

Legislation & Standards
Definitions and Basic Principles
Design Specification & Cable Installation
Special locations
Mains Position
Earthing & Bonding
Safety Devices
Safe Isolation and Working Practice
Power & Lighting Circuits
Inspection, Testing and Certification (both Minor Works Certificates and Electrical Installation Certificates)

The IS813 is very weak as far as I can see on instructions on electrics it's says RGIs must comply with ET101 and there bullet points on cabling, fusing etc but I haven't seen any mention to tools used but that could be me not seeing the wood for the trees.

If this is going to be a discussion about Irish gas regs then I would have to say they are weak on electrics, if you have a look at the Part P syllabus you will see the level of training I would like to see.

Also let's not forget RECI are responsible for RGI so there is no excuse for the lack of clarity.

I have a Sunvic digital thermostat (no neutral required) and it works just fine for me.

Can you provide a link to support this?

Here is the definition that CER provide. It states:

Examples of minor electrical works include:
● Replacement of an electrical accessory such as light switch;
● Replacement or relocation of light fitting where the existing circuit is retained; or
● Provision of an additional socket to an existing radial circuit.


The above conflicts with your position.

Regarding the 10 day course, GID is no longer available or on its last legs.

I can confirm that it is available and is being run in Finglas at present.
As it the 5 day GIS safety course. On the basis that I am a qualified electrician I am permitted to get my GID (Gas Installer Domestic) qualification by completing 15 days of training.

You must also consider that they are not 18 day courses but 9 week courses where they receive 2 days per week training but they "should" spend the rest of the week studying, revising & preparing with home study papers & questionnaires.

Sure, just like electrical apprentices should study during their 4 year apprenticeship.

Competent means suitably trained, qualified & EXPERIENCED, therefore if the RGI is all of these, then he is competent. Coming out of a 10 day course, he will not be competent in wiring a heating system, but equally he is not be, in the eyes of the courts, competent to work on a gas installation unsupervised.

I am not disputing any of this.

I must also point out that most experienced electricians will admit that most of what they learnt was in the first 5 years following completion of their apprenticeship.

Them neutrals are only for function of stats. Technically not part of the actual control circuit, so in my opinion, to say the circuit is incorrect due to not showing the neutral to stats is slightly over the top.

But it does look like its a diagram for mechanical stats. It's probably more outdated for gas boilers with having the valve contacts supplied by the circuit L rather than having the valve contacts connected to the boiler control loop.

True but your digital stat has a battery that powers a pcb which calculates the accuracy of the temperature.
Having a diagram like that will only confuse both RGI's & electricians if they do not understand the importance of the neutral within the stat. For example, the cylinder stat does not require a neutral as it does not require an anticipator as the temperature is not affected by external parameters.

I did state "or on it's last legs".
GID is being phased out this year & being replaced by an upgraded 18 day course/certification process. Qualifying criteria has also being changed since end of last year. So you will find establishments still offering the GID in its old format, but most centres offer this as a 12 day course, not a 10 day course.

Is 813 which RGIs work to once competence is proved covers the wiring requirements from the spur out.


Below is the link to the GID the paper RGI need to pass to prove competence, don't forget a RGI needs to learn to wire and safety check a S plan before a sparks inspects the wiring, rips out the wires:mad: then watches the RGI testing and rewiring the as S Plan to get it to work correctly before that RGI is deemed competent by the sparks.

I would add that I would love to see a dedicated electrical minor works certification course/process adopted into the Irish industry for RGI's. Equally, I would also like to have heating controls more detailed to electricians, especially more advanced controls that will be flooding the market in the near future.

The next manufacturer led push for boiler efficiency will most definitely be controls led, especially for gas boilers. For oil, it will be more basic.

Like it or not, most RGI's hand over their electrical part of their installations to electricians, & this can lead to a lack of the heating system achievement requirements being met. If electricians have a better understanding of what the heating system is trying to achieve, rather than the wiring itself, this would be a start to a better working relationship.

For example boiler interlock was unheard of to both plumbers & electricians until SEAI auditing came about for grant works. Now, everybody knows about it.
Why & when a gas boilers enters it's modualtion state when it is affected by certain parameters such as outdoor temperatures, return temperatures, etc. is also a requirement of electrical wiring. The importance of the location of the auto bypass valve is also critical when there is no permanent live/PCB live out to the MV grey wire.

Develop a heating control advanced course open to both RGI's & electricians is the first step, followed by an unannounced auditing system, similar to the SEAI system will bring compliance.

Point 3 or point 4?

Point 3 is extremely difficult to answer.
It's a bit like an electrician wiring a gas boiler but does not carry out an gas safety tests on said boiler to ensure all the safety devices are working satisfactory & enact within the specified reaction times. After all once the electrical connection is made, the electrician is putting that boiler "into service" as he cannot isolate & cap a gas supply to remove an appliance from service.

So if the electrician wires & connects a boiler, how does he know he has not unknowingly affected a gas safety control or indeed put into service a defective gas safety control? Hence, it is illegal for anybody other than an RGI to work on any gas appliance. It is also the reason why electricians are one of the accepted trades into the gas industry.

I do get your point though, but without specific criteria set out, we are leading back to a defined electrical minor works certification course that would provide the required training & use of required testing procedures & equipment.

I want to believe you but I can not find a link from CER showing this and neither can you. A verbal over the phone is simply not good enough for something that can turn legal.It can be a lot of mains voltage wiring especially when there is a large underfloor heating system with perhaps 12 zones.

However I can find plenty from CER in writing that defines "minor electrical work". I'm sure you agree that the heating control wiring that you are describing does not align with the definition given.

RECI do not have the authority to give anyone permission to break the law.

What you have described above is part of a commissioning process.
Is there any good reason what this can not be carried out as a joint commissioning exercise?

I have been involved with this sort of exercise at work on a far larger scale with far more dangerous gases (look up SiH4), solvents and various chemicals. We have a commissioning team, not individual so that there are people with expertise in each of the required areas.

In a domestic gas installation with multiple 230VAC controls a "team" of two is plenty, the electrician and RGI.

I do get your point though, but without specific criteria set out, we are leading back to a defined electrical minor works certification course that would provide the required training & use of required testing procedures & equipment.

At present we do not have such a course.
The course that you did is far more extensive and is not the norm for RGI.

I am absolutely saying RGI's carry calibrated equipment.
Flue gas analysers must be calibrated annually & gas seekers must be calibrated every 6 months & possess a calibration certificate.

Most electricians do not possess this equipment unless they are a registered electrical contractor. It has only been law for less than 12 months & most qualified electricians are not even allowed to work on the consumer unit of their own homes.

Not having a link does not mean it's not correct. RECI advertise that for electrical works, the homeowner must use a registered electrical contractor for their works but this is not true. It is only the works on the consumer unit that is prohibited.

The 2 systems both gas & electrics are very similar, both under the remit of CER & since RGI certification process has been tried & tested since 2006, you will find the RECI introducing a very similar process, across the board. It is a nice money earner for them. Heating controls & similar works may well become a certified process that requires a certificate upon completion. I don't doubt that but you will find that RGI will be allowed to as electricians are allowed become RGI's. The 2 are too inter-twined at top level.

So we have gone from the competent person able to replace or add in a socket or switch, to wiring entire heating system. They may as well wire the entire house.

I would have thought that there would be at least some rationale with work a competent person can carry out, such as not requiring testing, because it is simple basic tasks they can do.

Wiring a system by running wiring all around the house and making good quality connections, and earthing properly, and testing, may be another matter.

I'm talking in terms of what the cer say, rather than anyone's ability to perform the wiring.

So installing wiring in a house from a spur to the boiler, to the time clock, from time clock to the motorised valves, and from boiler to valves, is minor work now?

Its further evidence of the reasoning of only rec,s being allowed connect into DBs as purely being revenue driven. Because clearly the above heating wiring is anything but minor. But the cer don't mind rgi people doing it, because they will satisfy the revenue aspect.

Absolutely. The 2 trades are very similar & inter-twined so cooperation is key & welcomed.

I see a lot of domestic gas installs and as it stands right now two trades involved in a heating system doesn't work as well as a single RGI.

Two trades fitting a heating system leads to basic installs ignoring the level of controllability modern heating systems require.

Before modern gas boilers had this level of control you could find similar controllability in programmers i.e.. set back programmers incorporating outdoor sensors so the heat source would fire earlier on a cold day to achieve a set temperture at a given time, I have yet to see a installation of that type here other than underfloor.

Let's look at my boiler which comes with volt free links for external controls, it is very common for the volts free to be missed leading to a lack of cable, it is common to put 240v on the auxiliary and blow the board, it is common for a boiler to lack a permanent live, it is common for the potential of induction to be missed.

Now let's look at controllability, with my boiler you can have the it running at lower temperatures incorporating a outdoor sensor for the heating taking advantage of the condensing technology which is very important, the boiler can then run at a higher temperture when there is a hot water demand giving quick reheat times for the hot water cylinder.

The only trade I have seen wiring for the above is stand alone RGIs so they are setting the benchmark for gas heating controls.


For me the question of who wires is secondary to the standard of wiring, I'd prefer to see a improvement in the level of good working practise within all aspects of the heating industry as at the moment it ain't great.

With wiring I'd like to get rid of light switches with a bit of felt tip instead of multichannel programmers.

Room stats that are rarely positioned correctly often turning off the zone while other parts of it are cold.

I'd like to see switchable fused spur being the starting point of a wiring installation and be located within arms reach of the boiler.

I'd prefer if PCB housings got a bit of TLC instead of leaving them loose to allow for badly routed cables which leads to a loss of waterproofing putting the PCB at risk.

I'm not ignoring the good work of the professional sparks as this is a team sport and it's nice to see a tidy job, I don't see them often as I only get involved in dramas, but as I'm the one who often has to explain things to the home owner I do have interest in working towards a quite life which requires both trades having a better working knowledge of each other's trade to give the customer what their paying for.

I am absolutely saying RGI's carry calibrated equipment.
Flue gas analysers must be calibrated annually & gas seekers must be calibrated every 6 months & possess a calibration certificate.

I am referring to suiatbel test equipement to carry out the electrical tests necessary for an ETCI completion certificate. Test meters must be able to test insulation resistance, earth fault loop impedance, contunity and RCDs.

Most electricians do not possess this equipment unless they are a registered electrical contractor.

Agreed. But the REC they work for must have this to certify.

It has only been law for less than 12 months & most qualified electricians are not even allowed to work on the consumer unit of their own homes.

Correct, but off topic and has nothing to do with RGIs certifying electrical work.

The 2 systems both gas & electrics are very similar, both under the remit of CER & since RGI certification process has been tried & tested since 2006

Practices since 2006 has nothing to do with what became law in 2013.

Heating controls & similar works may well become a certified process that requires a certificate upon completion.

Perhaps, but I am referring to the present situation, not possible future events.

I don't doubt that but you will find that RGI will be allowed to as electricians are allowed become RGI's. The 2 are too inter-twined at top level.

Apples and oranges.
For me to become RGI take 15 days course attendance.
For a plumber to become an electrician takes 4 years.

No disrepect to plumbers intended (it would also take me 4 years to become a plumber).

So installing wiring in a house from a spur to the boiler, to the time clock, from time clock to the motorised valves, and from boiler to valves, is minor work now?

Its further evidence of the reasoning of only rec,s being allowed connect into DBs as purely being revenue driven. Because clearly the above heating wiring is anything but minor. But the cer don't mind rgi people doing it, because they will satisfy the revenue aspect.

So far nothing has been produced in writing to verify this.
I will believe it when I see it.

Absolutely. The 2 trades are very similar & inter-twined so cooperation is key & welcomed.

Agreed, but the suggestion is that RGI are permitted to do all of the wiring for multiple devices at 230VAC downstream of the spur. For a house with underfloor heating this can be hundreds of meters of cable and over 20 devices. How can this be "minor electrical work"? It does not align with the written definition.

That is not cooperation.

RGI's are capable of carrying the required calibrated test equipment if need be. Obviously, they should also undergo the current testing & verification course also along with a far more in depth electrical training module.

RGI is not a stand alone qualification in this country. It is an add-on. Therefore, the argument could be made that electricians should not be allowed to undergo the GID without first under-going a 4 year apprenticeship course. That's pretty much the same argument as yours in reverse.

I have no issue with RGI's only being allowed to wire from the spur. Even the bonding should be done by an electrician & tested & verified by the electrician.
My issue is as Gary's, where heating system electrical components are installed with no regard for what they do. That needs improvement.
I also think better training should be mandatory for both sides so that if nothing else, both parties have a better understanding of each other's trade & the effect of such.

Anyone can, but typically plumbers don't.

That is your opinion, of all the plumbers i know i would disagree with that.

Are you seriously suggesting that all RGI own calibrated test equipment, have completed the testing & verification course, and are permitted to issue ETCI completion certificates and do issue same?

I am seriously suggesting that RGI own calibrated test equipment. Keep relevant here and dont be going off topic, an RGI final cert signs off on all aspects of the installationso if you have an issue with that you need to take it up with the regulatory bodies, i didnt make up the legislation.

I don't know any plumbers that have completed the testing & verification course (I'm sure that there are some, but it definitely is not normal).

Do you think a testing and verification course should be part of an RGI training?

Just from being a qualified plumber and completing the GID (Gas Installer Domestic) qualification? How much time do you honestly think this course spends on ET101?

I know a lot of plumbers who are wiring houses every day of the week, its not uncommon for a plumber to both trades or vice versa.

In your post you are actually suggesting that plumbers should be permitted to certify electrical installations.

You are going off topic again, and i am not suggesting nothing.

Perhaps if you list out what this would actually entail you would see that this training for a person whose electrical training is limited to what was covered during a plumbing apprenticeship. Are you really suggesting that there would be enough time to bring this person up to the required level during the GID course (which can be for as little as 10 days) at present? Do you really think that this is a course aim, because it is not listed as one?

More irrelevant, why are you dragging other domestic work into this, we are discussing heating controls. Do you think in the 4 years of a plumbers apprenticeship that a trainee plumber does not get any training in electrical works of heating controls?

I presume you are referring to electrical underfloor heating (e.g. Devi) in this case I don't know anyone other than an electrician that would fit this.
A wet system would not have hundreds of metres of cable

it sure will..

this is obviously a mistake or a loophole if RGIs are working control circuits off fused spurs

that is not minor works imo

and I highly doubt any of them are competent to test their work

how many have calibrated meggers and test their work?

The question is why does the regulation body not require RGIs to use a megger to certify their electrical work.

It is the same in the UK.

Gas is a regulated industry and RGIs work to the regulators requirements.

there is no point using a megger unless they're qualified electricians

it takes years of training and experience to interpret everything fully when testing

Again meggers are not required by RGIs to certify heating installations.

By your argument newly qualified sparks shouldn't be allowed to certify their own work because they lack the experience to interpret their megger.

And I'm Part P certified so the mysteries of megger have been revealed to me:eek:
