Electric water heaters are relatively easy to install. They don’t require gas lines or venting systems, making the installation process simpler and more straightforward. With an electric water heater, all that is needed is a proper electrical connection and a dedicated circuit.
Performance
Recovery Rate
The recovery rate of a water heater refers to how quickly it can heat a tank full of water once it has been depleted. Gas water heaters generally have a faster recovery rate compared to electric models. This means that a gas water heater can heat water more quickly, allowing for a constant supply of hot water even during periods of high demand. Electric water heaters, while still capable of providing hot water, may take longer to recover and may not be able to keep up with high demand as efficiently as gas models.
Hot Water Capacity
Both gas and electric water heaters come in various sizes to accommodate different household needs. The hot water capacity of a water heater refers to the amount of water it can heat at a time. Gas water heaters often have larger tanks, which means they can store and heat a larger volume of water. This can be advantageous for households with high hot water demand, such as large families. Electric water heaters, although they may have smaller tanks, can still provide an ample supply of hot water for smaller households or those with lower hot water demand.
Consistency of Temperature
Gas water heaters are known for their ability to provide a consistent temperature throughout hot water usage. They have a faster response time and can quickly adjust the water temperature to maintain a constant level of hot water. Electric water heaters, while still capable of providing a consistent temperature, may have slight variations as the elements heat the water. However, advanced electric water heaters with temperature control features can help minimize temperature fluctuations.

Maintenance
Gas Water Heaters
Gas water heaters require regular maintenance to ensure safe and efficient operation. This includes inspecting the gas lines, checking the pilot light, and ensuring proper venting. Additionally, gas water heaters should be flushed annually to remove sediment buildup, which can affect performance and efficiency. It is recommended to have a professional plumber perform regular maintenance on gas water heaters to ensure safety and optimal functionality.
Electric Water Heaters
Electric water heaters generally require less maintenance compared to gas models. There are no gas lines or pilot lights to worry about, and the venting requirements are less complex. However, like gas water heaters, electric models should be flushed annually to remove sediment and maintain optimal performance. Regular inspection of the heating elements and thermostat is also recommended.
Environmental Impact
Gas Water Heaters
Gas water heaters have a relatively higher environmental impact compared to electric models. The combustion process produces carbon dioxide (CO2) emissions, contributing to greenhouse gas emissions and climate change. However, advancements in gas water heater technology have led to the development of more energy-efficient units with lower emissions.
