When it comes to heating water for your home, a gas water heater is a popular choice due to its efficiency and cost-effectiveness. But not all gas water heaters are created equal in terms of energy efficiency. If you’re looking to upgrade to a more energy-efficient model, you’ll want to consider factors such as the type of gas used, the size of the unit, and the overall efficiency rating. In this article, we’ll explore what makes a gas water heater energy efficient and highlight some of the top options on the market today.
Gas water heaters are classified as either natural gas or propane, with natural gas being the more common option in many homes. Natural gas is a cheaper fuel source compared to propane, making it a more cost-effective choice for heating water. However, if your home is not connected to a natural gas line, propane may be a more practical choice.
When it comes to size, the capacity of a gas water heater is measured in gallons, with options ranging from 30 to 100 gallons or more. The size of the unit you need will depend on the number of people in your household and your hot water usage habits. It’s important to choose a gas water heater that is not too big or too small for your needs to ensure optimal energy efficiency.
One of the most important factors in determining the energy efficiency of a gas water heater is its energy factor (EF) rating. This rating is a measure of how efficiently the unit converts fuel into hot water, with higher EF ratings indicating better energy efficiency. The Energy Star program, run by the U.S. Environmental Protection Agency, sets minimum EF ratings for gas water heaters to qualify for certification.
Now, let’s take a look at some of the most energy efficient gas water heaters on the market today:
