Moreover, what is direct venting?”Direct vent” refers to a sealed-combustion system in which air for combustion is drawn from the outdoors, and waste combustion gasses are exhausted to the outdoors. “Direct vent” does not simply mean that all gasses from combustion are vented to the exterior of the structure in which it is installed.Beside above, are all tankless water heaters direct vent? Gas tankless water heaters don’t have to use indoor air for combustion. Tankless water heaters can be vented in two ways: power-vent or direct-vent. Direct-vent units pull in air from outside the house, so they have two vents for intake and exhaust. Consequently, what is the difference between direct and indirect venting? Basically, the difference between the two is that the power vent water heater removes combustion gases from the atmosphere via a powered venting fan, while a direct vent water heater vents these gases into the outdoor atmosphere using a chimney or exhaust pipe.What is the difference between B vent and direct vent?B-vent appliances use a single exhaust pipe and draw combustion air from the room into the combustion chamber and up through the chimney. These devices are sometimes referred to as “natural-vent”. Direct vent appliances are sealed to the room.
