Fuel Options for Tankless Water Heaters

Tankless water heaterHot water is essential for most of your tasks at home, including washing and cooking. There are different heating options, with water heaters and electric kettles being the leading ones. The two primary water heater categories include tankless and tank heaters.

Unlike the conventional tanks, a tankless water heater produces hot water when necessary; therefore, reducing your energy costs by more than 30% and increasing efficiency by at least 50%. The water is heated immediately when you turn on your hot water taps, as it flows through heated coils. Here are the fuel options for heating these coils in your tankless heater in Utah.

Natural Gas

With this alternative, a gas burner is used to heat the coils, which then heat your water. The by-products of combustion, including water vapor and carbon dioxide, are passed out through the chimney. Gas-operated water heaters, however, are too costly to buy and install, though they generally qualify for federal tax credits.


Electric tankless water heaters are currently the most common option. They are cheaper to buy and install compared to gas and solar heaters. Electric heaters, however, do not qualify for tax credits since they are not very fuel-efficient. These heaters are also ideally used for point-of-use purposes, such as instant showers and dishwashers, instead of whole-house water heating.


Propane-fueled water heaters work similarly to natural gas. Propane is typically used in properties that have no access to natural gas. That said, the propane is supplied in large tanks for use on the property. Propane has low carbon emissions and increased fuel efficiency.

You may install your tankless water heater in any interior wall of your property or attic, regardless of its fuel option. The exact amount you will save with a tankless water heater depends on your tank’s flow rates and its installation. It is, therefore, important to have the heater professionally installed and its flow-rates appropriately set to meet your needs.
