Pressure relief valve install

[Leeboyguv]

Hi

I will be soon be removing f and e tank and going to mains, i will be installing expansion kit in the cylinder cupboard, my only issue is i have no where to discharge my safety relief,
My question is can anyone see a problem with cutting in prv by the boiler as this would be a better discharge point as right by external wall.

Thanks

Sorry it may be a typo , cutting in by the boiler ???
Either way , it must discharge outside .

By law, this work needs to be done by a plumber who is qualified to work on unvented hot water systems (sometimes referred to as having a G3 ticket). They should also be a member of a competent persons' scheme and should be able to advise you on all aspects of the install.

I’m guessing he means a heating system kit and not an unvented cylinder

You should know the answer but that’s a no you can’t move the prv away from the unvented cylinder

If you're G3 then you should have no problem deciding a suitable location for a PRV, whatever system it's fitted to.

Is the boiler suitable for use in a sealed system?

You may have confused people by saying "f and e tank and going to mains" instead of saying going to a sealed system

G3 has nothing to do with my question, yes boiler is suitable but thats not what i was asking, my copper cylinder is compatible as well if u like but thats not what im asking. as i said i posted to wrong group, people dont have the answer on this thread thats why they are going off the point, its fine i know its not a straight forward question,

Ok yes from gravity to sealed if thats where we are going!

Thanks

Then yes you can put the prv by the boiler

To be honest the way you put up the op wrong footed me, I also was confused about your conversion plans. you came to the correct forum be in no doubt of our competance
and now we can see your plans then you will get suitable advice . I would always site the
pressure relief as close to the pressure vessel as possible and with a direct and short path
to the outside...it really is a safety issue which superseeds cosmetics in my opinion
