Why do I need a direct vent water heater?
A direct vent water heater draws air for combustion from outside your home rather than inside. The exhaust gases and excess heat produced by your water heater are then vented back outdoors. This can help minimize safety risks when installing and using a gas or liquid propane tank water heater.
Is there a way to vent a hot water heater?

When to use a direct vent gas water heater?

What’s the difference between a vent and Direct vent water heater?

Is it safe to have a water heater without a vent?
Without proper ventilation of the noxious gases created by combustion, modern water heating would be a dangerous proposition. If you’re shopping for a solar- or electric-powered water heater, or if you live in a warm climate and plan on locating your water heater outdoors, then you don’t have to think about ventilation.
How are exhaust gases vented from a hot water heater?
Exhaust gasses are vented outdoors through a separate vent duct or through a separate chamber of the same pipe (this requires a double-wall vent duct). Direct-vent systems essentially “breathe” outdoor air, so they are not subject to the effects of backdrafting in the home.
