Hi folks,

We're looking at getting a small unit for a occasional use. We've been told that it should be installed indoors, in combination with a flue. We're thinking of installing it in an alcove right outside the back door. The area has a roof and 3.5 walls - so it has a huge opening. Do we still need a flue then? I'll try to draw up the plan of the small area, approx 1.5 x 2.5 m

Something like that. The top of that ascii drawing is the back door, which is closed most of the time. That huge gap is full height, stepping out to the back deck. Is that sufficient ventilation for occasional use gas water heater?

Cheers,
D.

What do you mean by "Occasional use"?  does this mean only when a hot tap runs, or will it be independently plumbed to a specific hot tap not frequently used, 

Will it be Natural gas ( and thus require gas work) or will you run it on LPG and run it off a gas bottle?

It will be used occasionally to wash our dogs, so it is an independent tap/hose. And it will be run off a LPG gas bottle.

Do you already have gas?

You can get electric califont, which might be cheaper overall if you are only using it occasionally, and if you don't already have gas

The other requirement was a certain degree of portability - gas is a bit better in that sense.

I doubt a flue would be necessary there - ventilation is obviously not going to be an issue. The flue is to vent the carbon monoxide and water vapour so it doesn't build up in the room. No chance of CO buildup on the porch, and condensation on the windows isn't a problem either.

There are rules that have to be followed and will be advised by the installer that is signing off on the work. Best talk to them about the clearances to windows/doors etc before putting too much planning into it.
