Combi boiler with rear flue

[SydDenham]

I’m drawing up a spec for a new kitchen and this includes a new position for a new combi boiler.

I’m currently thinking of a Vokera Compact A because, using the rear flue, means that it can be sited underneath the worktop (although I need to allow for a moveable hatch in the worktop over).

I wonder if anyone has any comments on the Vokera – I’ve no particular preference regarding boilers but this is the only one that I could find that would take a rear flue and hence fit under the work top (the Glow Worm rear flue is not long enough to work for me)

If you are redoing the kitchen cant you fit the new boiler above the worktop in a cupboard?

currently fitting a vokera vision 30c with rear flue, its got a 7 year warantee and looks pretty decent!
its 720mm deep. wouldnt like to work on it on my hands and knees under the counter though!!

Haven't done a Vokera, I did fit a glowworm - seem decent enough

 

[woodsy]

Vokera vision decent boiler - as with any if it's fitted correctly

Alternative Glowworm Energy

Regretfully the Glow Worm's flue is too short

No because the flat is built into the roof and the only space above the worktop that has a wall is where the hob needs to be..

Wow Thick walls

Wow Thick walls

Not thick walls but flue has to extend through the pitch of the roof. The Vokera one is okay but not the Glow Worm.

You do know you will require access to all the joints over the length of the flue

 

[Atouchofgas]

Will not be any it's a rear flue

Thanks.

The only joists involved will be the roof joists and the flue will go between 2 of them when going from the upstand wall on which the boiler is mounted through the slates to the external air.

in terms of your first post was actually are the dimensions we are looking at herE? I.e. gap for the boiler distance to outside etc

Four joints as flue will be in either 0.5 or 1m pieces

Is any body reading these posts? It's a combi with a direct rear flue - can not be extend only joint is the one connecting it a the back of the boiler

We op said its the only one that can be extended

 

[Atouchofgas]

It's telescopic but they can't be extended

Nearly 1m telescopic ?

No, I said that it's the only one (that I've found) that is long enough.

Here's a section - excuse the scribbled "computer writing". The flue is just long enough to give a tightest dimension to slate of 300MM

 

[Atouchofgas]

And is that flue 2m below the velux?
