Can You Install 3 HW Heaters to the Same Vent?
Have a 3 family but want to separate the hot water to each unit instead of a common hot water heater. Can I separate the hot water lines to individual hot water heaters and vent to the original hot water heater vent? Can I use PVC for the venting instead of steel?

Does this require a permit?
Code also is now 4″ and no longer 3″ vents.
It depends on how many BTUs you’re trying to vent and the size and daft (kind of like natural suction) of your chimney.
There are a few water heaters out there that can be vented with PVC, but you’re probably not using them. They have to be something like 92% efficient before that becomes a safe option.
