Electric vs gas water heaters

Return to the list

When it comes to water heaters, you’ve got two options: an electric water heater or a gas water heater. In order to help you pick the right water heater for your needs, let’s take a look at the features, advantages and disadvantages of each option. Besides the price, there are several factors you need to consider, such as the source of energy and size of the tank. And keep in mind that making the right choice might help you enjoy big savings!

The electric water heater

With its cylindrical steel tank, the electric water heater has an entry for cold water and an exit for hot water. The cold water enters the tank and is heated by the elements. Because hot water is less dense than cold water, it rises to the top and creates a layer, a phenomenon known as stratification. When you use hot water, it is replaced by cold water. In the tank, the hot water is maintained at the right temperature thanks to a thermometer and insulating foam. Tanks also come with one or two access panels for the thermostat, drain valve and pressure relieve valve to prevent water hammers.

Gas water heater

Even though propane water heaters are not as common as electric ones, they can be just as energy efficient. In a gas water heater, combustion heats the water. Just like in an electric water heater, the cold water enters through the bottom and rises to the top when hot. In this kind of setup, an aerator is required to permit the air flow required for combustion. There is also a tankless option called an instant hot water heater which is suitable for homes that don’t require a lot of hot water. This type of water heater is especially popular in Europe. In Quebec and elsewhere in Canada, gas water heaters are not as popular because electricity is much more accessible here.

The differences between an electric and gas water heater

What are the main points to consider when you are deciding between an electric and gas water heater? The cost of the purchase, the cost of the installation and its accessibility, the safety aspect, the space available, and energy efficiency are all things you should take into account.

ELECTRIC GAS
Cost of the purchase Lower More expensive due to its installation
Usage cost More affordable option because the cost of electricity in Quebec is not very high Long-term savings
Installation Simple and more accessible because it is electric May require the installation of a new gas line
Safety Safe Requires the installation of a venting system and a carbon monoxide detector
Space required Can be installed more easily in a tight space Because of safety reasons, gas water heaters require more space.
If there is little space, an instant hot water can be a better option because it is tankless.
Energy efficiency More efficient Consumes less energy

If you look at the table above, you’ll realize that there are several advantages to electric water heaters because they are usually less costly to purchase and easy to install, even in tight spaces. And thanks to the low cost of electricity in Quebec, an electric water heater is much more affordable. Whatever option you choose, the important thing to keep in mind is to pick the option that suits you and your consumption habits.
