Because the best way of doing one is the opposite way of doing the other and in some cases dangerous (L8 anyone?).

Having one appliance do both is easy peasy. The entire point of this thread.

No idear what that means but it sounds complicated

Have you watched the video I posted

Sorry; but I was very glad to have missed the 80's

I'm going to have a good read of this tomorrow when i'm sober
should be an interesting debate as I am unbiased as I crosstrade between the two trades
I will adjudicade if you's like

But the op could phrase the question better/make more sense, as I think
he must have had more to drink than me!

As a 'stupid plumber' I know how to carry out continuity, insulation resistance, polarity checks and earth loop impedance tests and have the kit to do it. I can also design and install far more complicated heating control systems than the one in this thread.

How many of these fully qualified sparks know anything about letby, tightness testing, gas rating, ventilation, G3 regs, Part L regs or flue gas analysis to name but a few of the things us 'stupid plumbers' need to know?

To be fair why would they need to?
same as you know about grouping factors, nature of supply,discrimination,cable selection,current IEE regs to name but a few

Heating is nothing more than a series of switches. There's noting complicated about it at all.

I dont think NTC's Opentherm & ebus are simple switches? in fact not switches at all. A 40 year old S plan is just switches - but things have moved on - honest.

That's wierd because I wire up loads of heating systems for a local plumbing firm, and it's always just switches.

Room stat = switch
Frost stat = switch
cylinder stat = switch
limit stat = switch
programmer = switch(es)
thermocouple = switch
NTC = switch
zone valve = switch

Yeah there might be some fancy electronics in there but all it really boils down to is lots of switches

If you think an NTC is a switch then you know nothing about electronics.

Course it is. It gets to a certain preset temperature and something either starts or stops. That's a switch.

Nope not a switch and agree with Dan too a thermocouple isn't a switch either
it's a bit like saying a photocell is a switch

Not that one, its a temp prob of a instrument

doesn't matter whether it is a instrument prob or not....it is exactly the same thing

You say that you crosstrade yet assume that the other heating installers on this thread have no electrical qualifications.

The OP has already stated that he has a degree in Electrical Engineering, I also have an engineering degree (electronics as it happens) and have my 2391 (earned the hard way prior to all the current multiple choice crap) and I think you will find we both have all the electrical test equipment that goes with it, along with a copies of BS:7671 and the IEE on-site guide. I wouldn't be surprised to learn that many of the other heating contributors are similarly equipped.

I would estimate that 30% of all my work is on heating control systems, burner motors, electrical diagnostics etc. I don't claim to be an electrician and nor do I want to be, but that doesn't mean that I know nothing about electrics. The examples you gave, grouping, cable selection,...etc. are not alien to me.

In summary, I know alot of heating installers that have electrical qualifications and are registered as such. I don't know that many electricians that have heating qualifications.

There's bad apples in all trades, (christ I've seen enough incompetent heating installers just as I've seen incompetent electrical installations), but it helps if we try and learn off each other.

I don't really know what this electrician/heating installer argument is about , but I would guess there is an element of insecurity being felt within the current economic climate.
