In a typical American household, heating water accounts for about 20% of energy expenses. If your water heater’s capacity is too low and it doesn’t consistently heat the water or it’s more than 12 years old, now is a great time to replace it. Here’s what you need to know about what type of water heater is the most energy efficient.
Source of Fuel
Water heaters can be powered by different sources of fuel or energy. The most energy-efficient way to power a water heater is with solar or geothermal power. Air-source heat pumps are also an energy-efficient method of heating water. Natural gas comes after these sources in terms of energy efficiency. The least energy-efficient method of heating water is with electrical resistance heating panels, which is the method used in electric water heaters with a conventional storage tank.
Conventional Tank Versus On-demand Water Heaters
Conventional water heaters with a tank are less energy efficient on average compared to an on-demand or tankless water heater. However, a conventional water heater powered with geothermal or solar power will be more energy efficient than a tankless water heater powered by electricity. The manufacturer’s literature will explain how many British thermal units (BTUs) of energy are used by the water heater.
Energy Star Certification
When you want the most energy-efficient water heater on the market, look for one with Energy Star certification. This certification indicates that the particular model of water heater is at least 20% more efficient than those with the same capacity, flow rate, fuel source, and type. Choosing an Energy Star-rated water heater could significantly lower your utility bills.
