Creative ways to minimise combi boiler exhaust

The plume kit is fitted incorrectly anyway on a Worcester you
Shouldn't cut or remove the pipe between the elbows so that needs fixing

+1. It needs at least 500mm between the elbows.

In this case down is preferable to up

the steam will be warm, so it will rise.

Can anyone suggest any technical reason why there should be a minimum of 500 mm between the PMK elbows?

I would be interested in this also.

Not in the open forum they can't, no. It's in the manufacturers' instructions, so it needs to be complied with

Why cant reasons for such a rule be discussed. Surely we are just talking about discussing the reason from a physics or chemical perspective. Unless you are indicating that the rule isn't based on any functional reason, and that the rule is therefore defunct.

Read the forum rules.

 

[CombustionGuy]

the reason is because the book tells you to and the manu overides everything

Bloody hell, I see a lot of pointless PMKs on woofter round here, without 500mm between the elbows!!! Someone seems to love doing it! I didn't know it was a no no

I know it is disappointing. Thankfully they are very understanding and glad we are renovating it. The skip will arrive soon, but probably after we have removed the bathrooms.

The reason you need the distance between the elbows is to stop the air inlet from drawing in vitiated air from the PMK outlet.

In the scenario pictured you can see exactly why this would be an issue, and why Worcester are worried about the minimum distance off the outlet.

flue heat recovery systems can minimise pluming , would cost a few squid though .

I was also told this, but if you think, a std flue is about 10mm away, makes me wonder !!!

I can't really see why it is affecting them anyway, seen worse. just tell them it can't be done. I would think it affects the people upstairs more.
