I'm replacing a 40 gal. tank water heater in the attic. I'd rather not have to move the old one down and lug a new one up the drop down ladder. So I'm thinking of installing a tankless one. 2 bathrooms, kitchen sink, dishwasher, and washing machine.
The old tank water heater is vented through the roof. I measured the opening and it's 9 inches through the roof and the pipe is about 3 1/2" outside diameter.
Is there a tankless water heater on the market where I can use the existing venting? I know it requires more air intake, but the attic has two large gable vents on either side.
Thanks for any help.
