Electrician wiring heating

[Gary80gas]

I had a debate with an electrician about correct wiring of regular Worcester boilers. I told him it needed to be wired to give the boiler control of when the pump comes on. This would mean up dating cables. He said using the original wiring just a switch line to activate both at same time was just as good and its how a lot of these boilers are wired. What do you think?

You mean no pump over run?

Yep that's what I pointed out to him.

If the boiler demands a PL&SL, that is what must be provided. I don’t really get the point of the post, TBH

They do work but not recommended it’s advised so no problem

Yep as said above or the use of a wireless pump overrun kit if not enough cables/too difficult to run a cable to pump location.

In my experience sparks have very little knowledge of heating electrics.

Just spoke to Worcester technical and it could invalidate warranties not wiring pump from boiler.

The magic word could and tbh don’t see they would invalidate

No pump overrun would decrease the lifespan of the heat exchanger (and probably other parts). Wire it to MI and then you cant have any problems.
