Electric vs Gas Tankless Water Heaters Showdown | (2023)

Electric vs Gas Tankless Water HeatersA dependable and efficient water heater is essential in today’s fast-paced society. Tankless water heaters are becoming increasingly popular due to their energy efficiency and on-demand hot water supply. If you’re looking for a new water heater, you may be faced with a typical choice: electric vs gas tankless water heaters. We’ll go over the differences, pros, and drawbacks of each in this detailed guide to help you make an informed selection. Let’s have a look at tankless water heaters!

How do tankless water heaters work?

Tankless water heaters, also known as on-demand water heaters, supply hot water only when it is required. In contrast to traditional tank water heaters, which store and constantly heat a vast volume of water, tankless devices heat water on demand, resulting in significant energy savings.

The Advantages of Tankless Water Heaters

Before delving into the technicalities of electric vs gas tankless water heaters, consider the following advantages:

  • Endless Hot Water: Tankless devices deliver a constant flow of hot water, guaranteeing that you never run out, even after long showers.
  • Energy Efficiency: Both models are more energy efficient than standard tank water heaters, which helps to lower utility expenditures.
  • Space Saving: Tankless units are tiny and may be mounted on walls, freeing up valuable floor space.
  • Longevity: Tankless water heaters offer a longer lifespan than standard tanks, which reduces the need for replacements.

Electric Tankless Water Heater

Energy Efficiency

Electric tankless water heaters are extremely efficient, transforming nearly all of the energy they use into hot water. They may, however, have greater operating expenses in places with high electricity rates.


Electric tankless water heater installation is often simple because it simply requires access to electrical wiring. When compared to gas systems, this simplicity might result in lower installation costs.

Operating Cost

Because electricity is frequently more expensive than natural gas, electric tankless water heaters may have greater operational costs in the long term. However, their energy efficiency can offset some of these expenditures.

Environmental Impact

Electric tankless water heaters are considered environmentally beneficial because they emit no greenhouse gases when in use.

Gas Tankless Water Heaters

Energy Efficiency

Gas tankless water heaters are likewise very efficient, with the added benefit of cheaper fuel costs in locations where natural gas is available. They provide continuous hot water, making them excellent for larger families.


As opposed to electric tankless units, gas tankless systems require a gas line and sufficient ventilation, which might raise installation expenses. Nonetheless, their effectiveness frequently compensates for the original cost.

Operating Costs

In areas with low natural gas prices, gas tankless water heaters are more cost-effective to operate in the long run.

Environmental Impact

While gas tankless water heaters are efficient, they emit emissions during combustion that may not be compatible with your environmental concerns.

Electric vs Gas Tankless Water Heaters? Which is right for you?

The choice between electric vs gas tankless water heaters is ultimately determined by your specific circumstances. Consider your location, budget, environmental concerns, and hot water consumption. Both varieties have advantages, and the best option varies from family to household.

Making An Informed Decision

Before making a final decision, investigate local energy rates, speak with a competent installer, and evaluate your hot water requirements. Your decision should be based on your budget, environmental goals, and lifestyle.


There is no one-size-fits-all solution in the electric vs gas tankless water heaters argument. Your choice is determined by a variety of circumstances, so take the time to assess your individual requirements. Whatever you choose, you’ll benefit from on-demand hot water and better energy efficiency.


Are tankless water heaters more expensive to install than traditional tank water heaters?

Due to unique needs such as electrical wiring or gas connections, tankless water heaters can have higher installation prices. However, their long-term savings frequently outweigh the initial cost.

How do tankless water heaters save energy?

Tankless water heaters heat water only when it is needed, avoiding the need to keep a large tank of water consistently heated, which saves energy.

Can I install a tankless water heater myself?

A tankless water heater should be installed by a professional since it requires electrical or gas work as well as adequate venting.
