Gas water heater in loft

[beardieman]

I am planning to have a gas water heater fitted in my loft. It could possibly go on the wall with a horizintal flue going out. However, if possible, I would have it rather fitted on the chimney. Is this at all possible or would this cause problems for the water heater when I turn on the multiburner downstairs?

Installations in lofts require a number of conditions. It is possible, but will cost significantly more.

you want the water heater fitted on the chimney?

I think he expetcs to share the chimney!

One wonders why he does not ask his gas registered installer!

I have got a spacious loft and the house is a semi. The bathroom is straight underneath the loft.
The water heater could go easily on the brick wall where there is no neighbouring property. Come to think of it, the flue obviously couldn't be fitted inside the chimney. So if it would go on the external wall, what are the conditions?
I obviously could ask a gasfitter to visit and advise / quote me but I rather get some advise first.

Any feedback is welcome. Thanks

I think that you should choose an installer and take his advice!

A minimum of pipework in a freezing loft is one aspect and probably electric trace heating on the pipes too! ( Whats that? )

is the loft insulated / boarded / easy accesable

So you know you cannot share the chimney, the gas heater needs a flue straight outside (shorted distance possible)

Thanks that makes sense indeed regarding a freezing loft. However, regarding the trace heating, I currently have my boiler in the garage and that does not seem to have a need for this and it must at least be as cold as the loft if not even colder.
