Can you vent a water heater with PVC?
A standard will be needed for plastic flue pipes that should include a temperature gauge and a high limit probe. Then PVC, CPVC and polypropylene flue gas piping can be safely used on high efficiency boilers and water heaters. This would be an answer to the dilemma of cost versus safety.
How much ventilation does a hot water heater need?
As a general rule, water heaters need 50 cubic feet of air per 1,000 BTUs/hr. For example, a water heater with an input of 40,000 BTUs/hr should be in a room (often the garage) with at least 2,000 cubic feet of air.
What happens if a water heater is not vented properly?

Airlocks do sometimes fix themselves, but it isn’t a risk worth taking. Airlocks occur when air becomes trapped in the hot water or central heating system. Vapour becomes caught in a high point of the pipework because the gas is less dense than the water in the system.
