They use less energy than standard models saving homeowners money on their utility bills while helping protect the climate.
Energy star solar water heater.
An energy star qualified solar water heating system can cut your annual hot water costs in half and is generally designed for use with an electric or gas back up water heater.
Solar water heaters come in a wide variety of designs all including a collector and storage tank and all using the sun s thermal energy to heat water.
Water heaters water heaters that earn the energy star come with gas solar or electric heat pump technology.
Demonstrate your environmental leadership by voting with your wallet for renewable energy solutions.
The type of water heater you choose will also affect your water heating costs.
Water heaters are the second highest source of energy usage in the home.
Use up to 30 less energy in your home by outfitting it with energy star certified products available across more than 75 categories.
For example an electric heat pump water heater typically is more energy efficient than an electric conventional storage water heater.
An energy star certified solar water heating system can cut your annual hot water costs in half and is generally designed for use with an electric or gas back up water heater.
The solar fraction is the portion of the total conventional hot water heating load delivered energy and tank standby losses.
They heat your water just like standard models but with much less energy saving you up to 3500 over a unit s lifetime.
One type of water heater may use a fuel type more efficiently than another type of water heater.
Energy star certified water heaters are an easy choice for energy savings performance and reliability.
After installing a solar system it is important to perform periodic maintenance to ensure efficient operation.
The higher the solar fraction the greater the solar contribution to water heating which reduces the energy required by the backup water heater.
Typical solar factors are 0 5.
Current specification effective date.
Solar water heating systems include storage tanks and solar collectors.
Solar water heaters are typically described according to the type of collector and the circulation system.
They can be used in any climate and the fuel they use sunshine is free.
Don t forget about maintenance.
Renewable energy tax credits for fuel cells small wind turbines and geothermal heat pumps now feature a gradual step down in the credit value the same as those for solar energy systems.
