What is a Direct Vent Gas Water Heater?

A direct vent gas water heater is one that allows the heated water to vent directly outside of the house and through a common vent that can be located anywhere in your home. This saves space because it does not have to go through a system of pipes or vents like your electric model does, and that means cleaner air and a more efficient use of heat in your home. Here are some things you should know about these types of heating units, as well as a few things you should consider before you decide which model to buy.
