did he say WHY you need 3 meters?

sounds like what you want to do is commonplace across the country.
whats your currents system? oil?

im not a plumber, but this sounds weird

Thanks for the reply yes were on oil but he says as the heat from a stove is unregulated this is why the distance is required for the header and expansion tanks to disipate the heat build up. Also says you cant by law use a pump to compensate as pump could fail without you knowing

surely expansion vessels are specifically designed for this situation?

i know of many dormer type houses that have oil with a soild fuel back boiler and its not an issue.

perhaps as this is a retrofit its harder to do...

anyway, i think youd get a better answer in the plumbing forum.

Can you put the tank any higher? DO NOT USE AN EXPANSION VESSEL on this job. The height of the expansion tank depends on the strength of the pump. and yes you cannot put a pump on the gravity circuit

Thanks for your help no i cant go higher the height of our dormer from floor level to ridge is 6.2metres so taking the upstairs rads into account we have less than the 3metres he says is required 😭

So what's the measurement from the top of the highest rad to the base of the expansion tank?

Get another plumber to look at it

Should be?

What's the criteria to be met, or is it a personal opinion?

No it's not that. There's other things to look at but if have to be there to see the whole installation.

When I say I'd need to be there I mean I'd need to see the existing pipe work, location of pumps etc. the cylinder must be higher than the stove too

No, stoves used to heat water / heating must always be fully vented, never sealed (e.g.with expansion vessels and safety valves).

Thanks for the reply, the plumber reckons as we dont have the 3metres it will be constantly venting thus we wont get the benefit from the heat being generated the 3metres would allow the heat to be transfered to the rads

I've often fitted stoves in dormers and hadn't 3m clearance. It depends on the pump and the piping layout
