A Guide to Water Heater Efficiency

Deciding on a new water heater can be a daunting process. You have a tough call to make! There are a few important things to consider — not the least of which being efficiency. We’ve pulled together information from ENERGY STAR and the US Department of Energy to create the following quick guide:


As you start shopping around for a new water heater, the first factor to consider is size. You need to make sure the water heaters you’re looking at can create enough hot water to meet your family’s demand. Otherwise, you risk losing out on efficiency. HGTV explains how to choose the right size here.

Fuel type

All water heaters need fuel. Of course, the cost will depend on type and availability. The US Department of Energy elaborates:

One type of water heater may use a fuel type more efficiently than another type of water heater. For example, an electric heat pump water heater typically is more energy efficient than an electric conventional storage water heater. Also, an electric heat pump water heater might have lower energy costs because of its higher efficiency than a gas-fired conventional storage water heater, even though local natural gas costs might be lower than the electricity rates.

Energy efficiency

To make sure you’re getting the most energy-efficient model, look at each water heater’s energy factor (EF). It takes the following points into consideration:

  • Recovery efficiency — How efficiently the heat produced is transferred to your water
  • Standby losses — The rate at which heat is lost from stored water in comparison to its heat
  • Cycling losses — The amount of heat that’s lost as water circulates throughout a tank and/or pipes
