Gas Storage Hot Water HeatersGas storage water heaters are the most common type in homes throughout the United States. Even with insulation, energy is lost as heat escapes through the walls of the storage tank.Newer versions that carry the Energy Star logo reduce stand-by heat loss, saving both energy and money. The D.O.E. estimates that the average family will save $30 a year when purchasing a unit with the Energy Star logo. The gas storage water heater is great for those on a budget.
Gas Condensing Water HeatersGas Condensing water heaters look similar to standard gas storage hot water heaters, but are very different on the inside. They are much more energy efficient because heat is captured from the flue gases.These energy efficient hot water heaters are great for large households, but are much more expensive than the traditional models. Tankless Whole-House Gas Water HeatersTankless whole-house gas water heaters only heat water on demand. They are much smaller than standard tank models, serving as great space savers.According to the Department of Energy, these space savers also save the average family $100 a year compared to the regular storage model. Models that carry the Energy Star logo have extended warranties and a life expectancy of 5-10 years longer than standard tank models.
Heat Pump Water HeatersHeat Pump Water Heaters use electricity to transfer heat from the air into the water. Heat is moved instead of generated, making these units very energy efficient.Because electricity is usually more expensive than gas, this is one situation where energy savings doesn't always equal cash savings.
Solar Hot Water HeatersUsing the sun to heat hot water is a simple concept. So why aren't we all using the most energy efficient method available? Because variables like where you live, how much sun you get, and how many people are in your house come into play. Of course, expense is also a factor. Solar water heaters can take 10 years to pay for themselves. The initial investment is great, but such a benefit to the environment if you can afford it.Considering the average water heater lasts 10-15 years, purchasing an Energy Star water heater is a long term commitment. It's good to do your homework. For more information on which type is best for your home, see the Energy Star website.
