Disadvantages of electric water heaters

Despite their many advantages, it's important to consider some drawbacks of electric water heaters as well.

  • Slower recovery: Electric water heaters typically have a slower rate of water heating compared to gas models, which may result in longer wait times for hot water, especially during high-demand periods.

  • Energy costs: While electric water heaters are more energy-efficient, the cost of electricity can still be higher compared to other fuel sources. It's important to consider the ongoing energy costs when evaluating the overall expenses.

  • Shorter lifespan: Electric water heaters generally have a shorter lifespan compared to gas-powered models, which may require more frequent replacements and increase long-term costs.

  • Power outage dependency: Electric water heaters rely on a continuous supply of electricity to function. During power outages, there may be no hot water available until the power is restored, which can be inconvenient in certain situations.

How do gas water heaters work?

Gas water heaters function by igniting a gas burner located at the base of a large tank. The burner heats the water stored in the tank, which can then be accessed through a tap when needed. As hot water is used, cold water enters the tank to maintain a constant supply. This continuous cycle of heating and replenishment ensures a consistent flow of hot water for various household needs.

Pros of gas water heaters

Gas water heaters are a popular choice for these benefits:

  • Cost-effectiveness: Gas water heaters are generally more cost-effective in the long run due to lower utility bills compared to electric units. Gas is often a more affordable fuel source, leading to potential cost savings over time.

  • Faster hot water delivery: Gas water heaters heat water more quickly than electric models, providing hot water faster when you turn on the tap. This can be beneficial for households that require immediate access to hot water, especially during peak usage times.

  • Longer lifespan: Gas water heaters tend to have a longer lifespan compared to electric units. This means you may not need to replace them as frequently, saving you money on replacement costs. With proper maintenance, a gas water heater can provide reliable hot water for many years.

Cons of gas water heaters

Despite their many advantages, gas water heaters also have some potential downsides:

  • Environmental impact: Gas water heaters contribute to air pollution as a result of burning natural gas, a fossil fuel. This combustion process releases pollutants into the atmosphere, adding to overall environmental concerns.

  • Risk of explosion: Incorrect installation or improper usage of gas water heaters can potentially lead to explosions. It is crucial to strictly follow safety guidelines and have a professional handle the installation to ensure proper operation and minimize the risk of accidents.

  • Higher maintenance costs: Gas water heaters generally require more maintenance compared to electric units. This may involve regular inspections, cleaning, and potential repairs. These additional maintenance requirements can lead to higher ongoing costs.

  • Longer installation time: Installing a gas water heater typically takes more time compared to electric units. It involves setting up gas lines, venting systems, and ensuring proper connections. Allowing for several hours of installation time is important to ensure a satisfactory and safe setup.

Are electric water heaters energy-efficient?
