Propane water heater

Do propane hot water tank (not tankless) heaters need a drain for condensate? Im looking to avoid installing a pump. No floor drains available.

ive heard condensate for gas fired appliances is acidic. Is draining to a municipal sewer allowed in Ontario? Seems like it’s not allowed in some areas due to the acidity and that it could damage drain lines.

That depends on the type. Traditional heaters that have a standing pilot and NO exhaust blower do not have a condensate drain and do not need a pump.

I assume that type then would require a chimney to vent?

Yes...... that is a correct assumption.

Most high efficiency water heaters with a powered exhaust vent fan can use PVC for their exhaust and this exhaust can be run horizontally which can make the chimney/flue/exhaust easier to run. But, these types of heaters may produce condensate and have a drain. To be certain look at the specs and installation instructions for the heater you are considering.

No floor drains available.
What is your plan in the event the Temperature and Pressure Relief valve should open and discharge water to the floor?

We have an existing electric hot water tank. The plan has been “cross your fingers”.
