Heating Wiring Centre

[Jack_88]

Hi everyone,

I just wanted some advice on the wiring box located by my water tank. I have no plans on amending the wiring or even touching it. But when I saw the electrician relocate a wire in the wiring centre 2 weeks ago, I took a quick picture after he had finished and have been meaning to ask this question.....

I was just curious if the terminal strip should have been cut as per the image shown, or whether this was standard practice? Seems a bit odd as all the wiring diagrams for most boiler/water tanks have the blocks connected together in a row of at least 8 / 10. (I know there is a specific Honeywell product that has it inbuilt)

At my old house, I had this all joined together so would be interested to know, so I can raise it with the builder as a defect.

many thanks....

Not sure it’s a defect if it works and isn’t dangerous. It’s a make shift wiring centre. Honeywell do wiring centres, as do others, but obviously whoever installed it went for this option, not that uncommon, but surprised to see it on a new build.

Thanks Chris

Yep, I had a Honeywell one in my last house, hence why I was curious.

Terminal strip is Terminal strip, it is what is connected into each terminal that makes it work, not if the terminals are all one block

Makes sense... thanks Ian

These are just a nightmare if fault finding is needed. A double box and one strip gives a better chance of identifying circuits.

Thanks Oilhead... it all came about because the boiler was constantly on without a call for heat from either CH zones or HW.

Must admit, I may get an electrician to undo all the mess and tidy it up and place in a neater wire centre so when I fit the drayton wiser and get rid of the Wired Stat

Nightmare !! What fookin nightmare ?? If you cant identify what is what in that box then maybe you are very inexperienced or need more training.
As has already been said, It matters not if the terminals are in a row of 10 or divided. It appears that The wires have been sleeved to identify blues used as live !! So what is the problem.
I would much rather find a JB wired like that than some of the Honeywells Rats nests wiring centres !!

...........But I would much rather find a junction box with a bit more room in and a static block that keeps all the wiring still whilst testing.

Use a Drayton LWC1 . Far better than the other offerings.

I agree - numbered and with a diagram relating to the numbers. Maybe a tangled mess is fine, if all you work on is domestic heating systems every day. I need to investigate mine, maybe every few years - a neat little diagram in the lid is a great help.

Why ? does your wiring swap itself around every few years ?

No, to investigate issues with my heating system every few years, between fixing lots of other things. An as installed diagram to refer to, makes doing that so much easier. If all you work on is heating systems, it is much easier to work without a diagram to remind you.

I am a gas engineer, not a heating engineer, I see a handfull of wiring centres in a year these days unless I am fitting the so called smart thermostats, I have absolutely no problem knowing what is what, simply follow the factory fitted cables from the zone control, every other wire can be any colour

So basically, YOU ONLY DEAL WITH ELECTRICAL ISSUES ON HEATING SYSTEMS? Unlike me..
