Domestic water heating accounts for about 15 percent of the energy consumed in homes. Water-heating energy costs can be managed by selecting the appropriate water heater type, using efficient system design and reducing hot water consumption.
With gas water heaters, venting problems and toxic gas build-ups are real concerns. Electric water heaters have no flame, no carbon monoxide, no potential leaks in exhaust flues or fuel lines. As homes become tighter, air quality becomes more of an issue. With electric water heaters, you don't have to worry about unburned hydrocarbons in the air your family breathes. |
