Moving Combi

[kirstmin]

Hi all, great forum so I thought I'd ask a question!

I am doing the preliminary stuff with a mind to extending our flat to add a bedroom next to the kitchen - the extension will be 1 story, flat roof but the building is a 2 story terrace (we are on the ground floor and another flat is upstairs).

Currently our combi is on an external wall which, if we go ahead will end up being the internal wall between the kitchen and the bedroom. So I dont know what to do with the combi as if we go for the extension there will be no external wall from the kitchen.

Is it possible to have a flue that goes into the proposed new room and then out, vertically through the new extended/flat roof? And what about the overflow/runoff pipe? Where could that go? Maybe this just isn't possible?

I will get a professional in to have a look once Ive sussed out the options.

Many thanks,

kirsten

Depends on the make and model and age of your combi. Vertical flues are available but if it is old then it may no longer be made.

Discharge pipe could run a skirting level thorough new room to out side at worst.

Hiya, thanks for the info. The combi was purchased 18 months ago when I did the kitchen, so its relatively new.

Many thanks

Shouldn't have no probs with the flue then. Is it condensing combi? You may need help with the condensate drain termination if there is no drain out side where the new external wall will be.

Thanks again. No, I dont think it is a condensing combi, I will check when I get home. The current drain pipe doesn't go to any drain, its just a long piece of copper pipe at the minute.

if it isnt then you cannot really move it as it is a new install and must conform to part L1

What can't be moved.

a non part l compliant boiler

I know this has been done to death but until i get a definiative answer I will go with what i was told on my EE course

Move it - but a Corgi registered engineer almost certainly wont certify it as OK unless you offer him a bribe. Like the man said, if it aint condensing it aint compliant. B&Q do a reasonably priced Ravenheat combi which is on special offer at the moment. You could get this baby installed and commissioned for £1200 (plus VAT) - a snip!

Hope this helps!

Corgi I've been told in the past by CORGI (not you ) that it is allowed

 

[corgiman]

Yeah yet another case of NO ONE knowing there arrse from their elbow when it comes to New Labours legislative competancy

 

[kirstmin]

Well I had the boiler installed 20 months ago so this must relatively new? I dont think I fancy paying the same guys to put a new one in after they took £1500 a short time ago!

Either way, the question I made was not about MOVING the bioler, I want that to remain in the same place - I cant be doing with moving it. The question was could I vent it out vertically with a flue, through the roof rather than straight out the wall as it is at the minute (because the wall it goes out of is going to change from external to internal with the extension).

Thanks

Have the flue altered so it exits the proposed flat roof.

Check in the manual for fluing opptions, or post make of boiler

Most vertical flues have to be at least 600 mm from the nearest part to any vertical surface.

So dont expect the flue to be tight up against the wall!

There are limits on the maximum length of flues depending on boiler model.

The vertical flue terminal is a special part so you cannot just use the existing terminal and turn it upwards!

Its often easier to take the flue vertically upwards INSIDE the house and exit above the extension using the horizontal flue. It looses a small area in the room above but is much neater and cheaper.
