Is it possible to install an external oil boiler in an old out door store cupboard? This model does not have a sealed flue available, but then because the space only has the boiler inside it and is not air tight, is this important? I could even replace the door with a louvred door if that would make a difference?

Any advice would be great

Thanks
 
Flueing options on external boilers are normally very limited.
Make of boiler you want to use and a picture and sketch of what you intend would be useful.
 
The 'cupboard/store' is shown in the attached and the boiler is Grant vortex pro 36.

Whilst the store is obviously enclosed but a cold, ventilated space, is it still considered and internal space. Would installing a door of louvres change anything?

Thank you

Think you will struggle to get a external Grant in there
Maybe look at the Grant green flue system that can be fitted to external boilers it's twin walled .
You would probably have to relocate condensate trap if you had no access to rear of boiler.
Certainly needs a dedicated air supply tho louvered door probably overkill!
Probably the simple solution is to put a slab down and have boiler outside.

I was looking into that. The boiler is about 650mm wide I think, that cupboard is 850mm internal. I am aware of the pipes that stick out either side, if the installer can fit these so they don't protrude too much I assume it'll be okay, but need the installer to confirm this.

The condensate is a flexible pipe I think, where to have it drain into is another issue.

Could this just be a largeish vent in the door?

Will look into this but would have to be about 4m out, behind the shed so it's out the way and not am eyesore
 
Where it is now, out of the way in a space we don't need. The new boiler is a year old and free. So a good price
 
As the boiler is that price you probably wont mind hacking it about a bit.
Relocate condensate trap externally (grant make longer hoses)
Loose existing flue cut a bigger hole in right hand panel get a low level flue kit grant number ez200b maybe need a extension x200s .
Cut hole in external wall job done.
Don't forget decent system filter and remote fire valve.

There's already a flue exiting at high level so I'll try to use the existing hole. The oil tank is also on the other of the brick wall so I'd like to stay above.

Sound like very good ideas

Thanks for all your advice
