Energy Efficiency Ratings
To compare the energy efficiency of different water heater models, it’s important to look at their Energy Factor (EF) or Uniform Energy Factor (UEF) ratings. These metrics indicate how much of the fuel or electricity used by the heater is converted into usable hot water.
The higher the EF or UEF, the more efficient the water heater. For example, a traditional storage tank heater might have an EF of 0.60, while a high-efficiency tankless model could achieve an EF of 0.90 or higher. Heat pump and solar water heaters often have even higher efficiency ratings, sometimes exceeding 2.0.
Fuel Sources and Considerations
Water heaters can be powered by a variety of fuel sources, each with its own cost and environmental implications:
