Determining a Water Heater's Energy Efficiency

Before you purchase a water heater for your home, it's important to know how energy efficient it is. Usually the most energy-efficient water heater models or systems are more expensive. However, if you purchase an energy-efficient model, you may save more money in the long run on your water heating bills than if you purchase a less efficient model.

Here you'll find information about how to determine the energy efficiency of these systems:

• Solar water heaters
• Storage, demand (tankless or instantaneous), and heat pump water heaters
• Tankless coil and indirect water heaters.

Don't choose a water heater model based solely on its energy efficiency rating. You also need to consider its:

• Fuel type and availability
• Size
• Costs.
