How would you do this ....................

[Octopus]

Customer is having an extension. In the extension, wet under floor heating to 3 zones is being installed.

The GSR says he wants a plug adjacent to the manifold .......... and he will plug the manifold etc into that.

This means the boiler will have 2 supplies..........

Do you.....

 

[Ian1981]

Am I right in saying they will be 3 zone valves for the zones controlled by individual room stats?
I’m a bit lost to the purpose of the socket.


Edit to supply the pump etc on the manifold.
If he insists then you have to provide appropriate warning labels.
Insist it should be supplied from the same circuit.

I would never have two supplies to a heating system but seen it done many times by the wet trade!!!
As far as i would be concerned you need perm L, switched L, N &E which you obviously know. There might be a switchable /triple pole and earth socket out there for them to plug into at a later date

 

[elsparko]

why would you even need 2 supplies?!?!

 

[elsparko]

why not just connect the pump for the manifold as per normal?

 

[Octopus]

I'll update this in the morning with what I said to him .............

 

[Leesparkykent]

Are the manifold and valves actually going to be switching the boiler or just opening and closing on demand from the thermostats when the existing heating is running?

switching

 

[Leesparkykent]

switching

So some how there needs to be an interconnecting cable from the new manifold position back to the boiler or wiring centre so why not just run a 3 core and earth so you have LNE and SL?

That's NOT the question on the thread!

 

[Leesparkykent]

Surely it's the most logical approach? Who's job isit to provide the SL if the plumber only wants a socket?

All you are doing is outlining the 3rd option on the poll

No I'm not, IMO there should be 4 options. If I was responsible for wiring in the S/L then I would provide a 3core and earth and terminate it into a triple pole isolator at the new manifold position. If I wasn't responsible for providing the SL then I would do as he asks but explain to the plumber/person in charge of the job my reservations.

I very deliberately had the 3 ................. so opinions on those please ....

BTW you didn't answer my recent pm

What is a GSR ?

What is a GSR ?

Gas Safe Registered installer

 

[Toneyz]

IMO dangerous.

 

[Wilko]

One supply for system

 

[AJshep]

Some GSR are arrogant, id raise my concerns with the GSR, and customer. At the end of the day if hes connecting it its his problem.

The heating controls should be on the same circuit however if hes intending using a different circuit for the UFH and manifold zone valves he could use the trigger wires from the valves to operate a relay that pulls in the heating control circuit that way the boiler is only controlled by one circuit, and the manifold is a completely seperate.

Does a GSR have the technical ability to do this ? If he doesnt want to listen to advise maybe he does, maybe hes going to do it through a RF relay.

Much easier to keep it on same circuit IMO.

Do you.....

Are you sure you two are not at cross purposes, and he wants a socket instead of FCU, and he assumes you'll just feed it from the wiring centre.

I sense your being a bit touchy of late Murdoch? Perhaps another holiday in the States will calm your nerves
