Electric vs Gas Tankless Water Heaters

Electric vs gas tankless water heaters-which is suitable for you? Tankless water heaters are all the rage these days and for a good reason. They offer several benefits over traditional tank-style water heaters. But which type of tankless water heater is right for you-electric or gas?

This article will explore the pros and cons of each type of tankless water heater to help you decide which is suitable for your home.

Electric Tankless Water Heaters

Electric tankless water heaters are powered by electricity, making them more energy-efficient than gas models. They also tend to be smaller and lighter than gas models, making them easier to install. These water heaters are a good choice for homes with less hot water, as they have a limited flow rate.

Gas Tankless Water Heaters

Natural gas is the fuel source for gas water heaters. Some of their key advantages are instantaneous delivery of hot water and higher output of gas heaters. An interruption of electricity won’t affect a gas water heater.

While they need professional technician inspection and maintenance more often, gas heaters also have a lengthy projected lifetime. Due to the gas over their lifespans, gas models may develop mineral deposits, requiring servicing and draining, and need safety checks.

Electric vs Gas Tankless Water Heaters: Key Differences

There are several key differences between electric and gas tankless water heaters. These include:

Initial Cost

Electric water heaters are much less expensive than their gas equivalents at the time of purchase. Gas tankless water heaters often cost a thousand dollars or more, particularly for higher quality systems with electronic ignition systems, while whole-house electric tankless water heaters cost between $500 and $700.


You should also consider the installation cost and where you may put the heater in your house.

Installation costs for electric tankless water heaters are often lower. Since they are smaller units, ventilation is not required. Typically, they are not sophisticated units or systems. A tankless electric heater can frequently fit in a place as small as a closet. They are also often lighter, so one person can carry and install them.

On the other hand, you need to properly vent gas tankless water heaters. You may also require the installation of a gas line. All these factors add to the installation costs, typically several hundred dollars more than electric models.


Electric tankless water heaters are more eco-friendly than gas models. They do not produce carbon emissions, making them a good choice for homes trying to reduce their carbon footprint. Electric tankless water heaters are also more efficient, as they do not lose heat through exhaust vents.

On the other hand, gas tankless water heaters produce carbon emissions. They also tend to be less efficient than electric models, losing heat through their exhaust vents.


Electric tankless water heaters are generally considered to be safer than gas models. Gas tankless water heaters can produce carbon monoxide, which can be dangerous if not properly ventilated.

Electric tankless water heaters also do not require a pilot light, which can be a fire hazard.


The type of tankless water heater right for you depends on your individual needs and preferences. If you are looking for an eco-friendly and energy-efficient option, an electric model may be the best choice. A gas model may be a better option if you need a unit that can produce large amounts of hot water. Ultimately, the decision comes down to your personal preferences and needs.
