Hot Water Tanks
Water heating is important, and not just because it feels good to step into a hot shower. Water heating is the third-largest energy expense in most households, coming in just behind heating and cooling. A little knowledge about water heaters can go a long way toward protecting you from losing your hot water or paying more than necessary for this necessity.
Types of Water Tanks
The most common type of gas water heaters is the atmospherically vented type that uses a natural way to move the flue gases from the unit out. Atmospherically vented heater uses a vertical metal pipe connected to the chimney, where the hot flue gases rise naturally through the draft hood and flue pipe, and out in the atmosphere. The advantage of using this type of venting is the low cost of the unit, installation and operation.
Power-vent water heaters use a mechanical fan to move the by-products of combustion outdoor. Though they are more expensive, they bring more flexibility during the installation. The venting system can be installed vertically, horizontally while the unit can be far away from the point of termination. Found in most new homes built since 2007.
Direct-vent water heaters are designed with the sealed combustion chamber, and they use the horizontal flue pipe directly through the external wall and out. Much the same
