A gas water heater that has been neglected, improperly installed or poorly vented could leak carbon monoxide, which can be downright deadly. Tankless water heaters, which heat as needed and do not store water, are powered by natural gas or propane, so they also must be vented properly to get rid of carbon monoxide.
In this way, what is a down draft diverter?
Draft diverters, or draft hoods, gather the exhaust gases from the flue(s) of a water heater in order to be safely vented to the exterior.
What is water heater Backdrafting?
“A current of air or water that flows backward down a chimney, pipe, etc.” So, essentially, a water heater backdraft is when exhaust gases from an atmospherically vented water heater spill out into the room instead of leaving the house through a vent.
How does a draft hood work?
The draft will change in the chimney as exhaust vents towards it – especially when going from cold air to hot. A draft hood is placed above the upper most part of the gas furnace to draw air into the chimney and makes it possible to draw more or less air through the chimney as necessary to create a constant flow.
