Worcester Boiler 24i Junior

[CharteredEngineer]

There is usually an NRV (non return valve) in the boiler, this might be passing.

Are you suggesting that Worcester usually fit an NRV but then sometimes ( unusually ) they dont fit it?

Why would any manufacturer want to fit one in the boiler?

It is not uncommon to see boilers with NRVs, not sure why everyone called me a tit when its pretty common on a variety of machines out there.

Anyway to illustrate my point, the remeha avanta has one its on P49 of their manual.

I would say it very uncommon to find a NRV fitted to a combi. I have never encountered one. I suspect the Remeha MI are wrong. That's a standard Fugas manifold...containing the magnetic shuttle, strainer and sometimes flowlimiter.

What other boilers have NRVs?

Mini expansion vessels are no longer fitted to normal combis so how would excess pressure be accomodated if manufacturers fitted NRVs. Normally DHW expansion is accomodated via backflow into the mains network.

Broetje and Junkers spring to mind.

So when did anyone last see one of those in the UK

There are no Broetje & Junkers boilers legally sold in the UK for domestic use.
It does sound like you are clueless.

In which case you must be worse than that.

Fabulous reply from a superior intellect. Do all Chartered Engineers lose the ability to accept they are wrong from the day they get their "quals"?

So I am clueless because I point out that your example of a boiler with a nrv is actually not legally sold in this country?
What will you come up with next, your dad is bigger than mine? You can't even google properly.

 

[CharteredEngineer]

remeha avanta, sold in the UK and has an NRV - give them a ring and see what they say.

I'm pretty sure the ATAG machines also have NRVs in them. Not sure about the current ones but the blue machines that were recently replaced had them immediately adjacent to the plate heat exchanger IIRC.
