Rose said:I highly recommend tankless water heaters. A bit more expensive up front, and the vent is 5 inch, but the savings come with not keeping a tank of water hot 24 hours a day.

I do a lot of plumbing and the only tanks I've EVER seen with a PVC vent is a POWERVENTED model. They are carried by both Lowes and home depot in my area. Why dont you try a search for a DIRECT VENTED water heaterhey vent through the wall and also pull combustion air from outside. Direct vents are often used on mobile homes.joan from zone six said:have heard there are some gas water heaters so efficient they can be vented with a plastic pipe - yet, at the big box stores, all i can find require double wall vent metal pipe - does anyone know brand names of the super efficient heaters?
Are there timers for gas water heaters that would do this? Then I wouldn't have to be smart enough to remember!SueD said:Me too... But if you don't want to go that way - I've saved a ton of money with just remembering to turn the blasted thing off and on every day...
I started with an experiment: turn it off after DH left for work and my shower was done - then back on just before bed (he can't seem to remember in the morning).
Even though the gas rates went up by almost double this year, I saved $40 in February over January's bill - and $70 from last year - which was warmer!!! You do have to drain them a little more often doing it this way - just to prevent 'catching' something from whatever bacteria could build up in the sludge, though.
