Balanced compartment flue

[Gasguru]

Anyone know if its possible to get a combined flue/air vent terminal to fit a balanced compartment. The flue is 150mm diameter.

Building work necessitates removal of the existing high level flue so I'm looking at the option of creating a balanced compartment for a Kingfisher CF150 (57KW input).

I've found this but they don't look very attractive and tend to be for commercial sized boilers. http://www.sunpipe.co.uk/other-products/vbf/index.php

I think you would get a better answer from a more specialist website gasguru.

www.argi.org.uk maybe

Though I'd start by testing the pro's here first.

There are flue suppliers who should know what's about (try Yell) and a place near me makes ducting and things up in galv and has some useful fittings , Eg I bought a flange to hold a 6" flexy up to a big terracotta airbrick. Don't have the names handy but if you email me..

Came across a big boiler in a restaurant basement once which only had a high level vent, but about 12" square. Used a flexy fixed inside it to dangle down for the low level. Room temp dropped about 20º.
