Vaillant ecotec plus 630 system boiler

[tomnoton]

Hi guys,

I have recently been called out to have a look at a Vaillant ecotec plus 630 system boiler which is wired to a standard S-PLAN set up.

The customer has had a john guest underfloor heating installed in some new rooms downstairs and has been totally wired up and ready to go apart from the boiler connection.

The underfloor system does not have its own zone valve but after speaking to john guest it shouldn't need one being this close to the boiler. The pump out of the boiler is pumping to the manifold and the pump on the manifold and actuators do the rest.

We just need to connect the underfloor heating control centre into the vaillant boiler. I am meeting the electrician there tomorrow who wasnt to sure where to connect in. We are planning on calling vaillant but just wondered if any of you guys have done this before with this boiler?

Thanks

If your Gas Safe then look above for reference to joining the combustion chamber for boiler spesific advice.

as a note, underfloor heating wiring connects to a boiler like any control/clock/stat does.
