Which Is Better Propane or Electric Tankless Water Heater?

There are many factors to consider when choosing a tankless water heater, including fuel type. Propane and electric tankless water heaters are the most common choices, but which is better? Well, it depends on a few factors. Let’s take a look at propane and electric tankless water heaters to see which one is right for you.

Propane Tankless Water Heater

Propane tankless water heaters are typically more expensive than electric models, but they also have a higher capacity and deliver hotter water. Propane also burns cleaner than other fossil fuels, so it may be the better choice for those who are concerned about its impact on the environment.

Electric Tankless Water Heater

Electric tankless water heaters are less expensive to operate than propane models, but they have a lower capacity and may not be able to deliver as hot of water. Electric tankless water heaters are also easier to install, so they may be the better choice for those who are not comfortable working with gas lines.

In general, electric tankless water heaters are less expensive to operate than propane models. However, propane models often have a lower initial purchase price.

Another key factor to consider is the availability of propane or electricity in your area. If you live in an area with unreliable propane service, an electric tankless water heater may be a better option. Electric tankless water heaters are also a good choice for homes that are not served by a natural gas line.
