Hi...

Apparently my hot water heater is shot!! So I am considering an On Demand Water Heater. I've seen a couple installs but no one posted photos of how the heater vents to the outside? I know to use the high temp hose, but do you vent it through the roof? I plan to mount the heater behind the fridge like everyone else. I already have a 3-way fridge so propane is right there.

I was going to have to replace the long 5/8" hoses to the original heater anyway, but now I can send the hose back to the parts store.

Any other pro's and con's to using the On Demand Heater?

Thanks guys,

Steve

Steve,

Someone will post a link to the photos but recently I saw a post here about the exact thing you are planning and there were photos. I believe the venting for the heater was just piped strait up and utilized the fridge vent.
