I have a high efficiency furnace. When it was installed they capped the old pipe to the chimney.
I will be needing a new hot water heater and roof in the near future.
My thought is to use a power vent ( high efficiency) hot water heater and then eliminating the chimney. I would cut off the flue in the attic and have the roofers eliminate the chimney.
I looked on-line for a power vent hot water heater and the only ones I saw was a Sears. I stopped at the local Sears and asked about it and they said it is in the literature but they don't know anything about it. They would charge me $35 to come out to look at it before they would give me an estimate. At the very least, the heater cost at least twice as much as a standard unit.
Does my idea make sense? Is there another source for power vent hot water heaters?
