Hello,
I'm working on SWMBO on agreement for getting rid of the Rayburn (mains gas cooking and system boiler all in one) and replacing it with a normal system boiler for CH and DHW and a proper cooker.
One particular carrot I'm dangling is that the boiler could be out of the kitchen entirely and instead placed behind the dwarf wall that partitions some of the roof/floor space in our chalet bungalow. To my way of thinking, putting it up there is actually nearer the cylinder so less heat loss.
However I've identified some other reasons why it might not be possible to have it in this space, but I don't know if they're solid enough concerns or against any regs.
a) Gas run from the meter is longer
b) Roof space will need extra venting
c) A modern boiler might be too big to fit in there
d) Fire risk from all the bare/exposed timber in there
e) Exhaust tube/stack/pipe may be too short or must exit horizontally (which is probably inappropriate for the location I have in mind
f) Boiler is at the same height as the cylinder and so somewhat contrary to a natural thermo-syphon if one is required (only solid fuel???)
g) It's really quite hot up there in summer, obviously not as hot as the boiler internals.... but is there an ambient temperature limit that should not be exceeded for reliable, long term operation of any boiler?
h) as per above, obviously in the winter it's much colder up there - and until it is warm (let's say the first time it fires of a cold morning), a large chunk of metal in a cold space tends to attract condensation. Not quite as bad as having one outside. Do people have them fitted outside?
Any other things to consider? This project is still at the drawings stage, so it's beneficial to know the limitations before progressing too far. Running the condensate to a drain shouldn't be a problem.

That loft space is massive compared to what I have available though (pic to follow). Thanks for the guidance.
