New unvented cylinder and boiler installation

[wrighty208]

Hi, quick question...

I have just had a new Worcester Bosch 30CDi System boiler and Megaflo Eco 210i installed in my loft (by a local G3 installer).

I don't know much about these systems but am doing a lot of reading up to get familiar with how it all works.

So my question is, should there be an Automatic Bypass Valve fitted somewhere? Something to do with pump over-run?

Many thanks

auto bypass will be in the boiler

Thanks for the response.

I believe the system is configured as S-Plan Plus (I have 3 motorised valves for HW, CH and underfloor heating).

I checked with Worster Bosch this morning and they said I should still have a separate bypass valve fitted, is this correct? If so I'll get on to my plumber again.

Cheers

It's a requirement of the building regulations to fit an auto bypass external to the boiler.
