Propane vs. Natural Gas Tankless Water Heaters

Last updated 5 years ago

Unlike conventional water heaters, which constantly keep a supply of hot water sitting in the tank, tankless water heaters only heat water as it is needed. Replacing a conventional water heater with a tankless one can result in a 34% increase in energy efficiency. But before you invest in a tankless water heater, you should find out whether a propane or natural gas unit is better for your home. Here’s how to decide whether you need a propane- or gas-powered tankless water heater.

Most Homes Use Natural Gas

The American Council for an Energy-Efficient Economy (ACEEE) says that natural gas is the most common fuel source used to heat water. 40% of homes use electricity to heat water, while a smaller percentage use propane or heating oil. If your water heater is already powered by natural gas, it’s not a bad idea to stick with a natural-gas tankless water heater for the sake of both convenience and cost. If you have access to it, natural gas is a more cost-effective fuel source for powering tankless water heaters.

Natural Gas is Not Available in Some Areas

Even though natural gas is the most common fuel source, there are still some areas that do not have access to natural gas. These homes will need to use propane tankless water heaters. Fortunately, if you live in an area without access to natural gas, you can get propane delivered to your home regularly.

Propane Tankless Water Heaters Have Certain Needs

If you choose to install a propane water heater, it will need to be properly ventilated for proper safety. Some homes are already set up with ventilation systems, while others will need to have it installed by a professional.
