Benefits of Electric Water Heaters

Choosing an electric water heater for your home comes with several advantages, especially if you reside in the Greater Toronto Area where efficiency and safety are paramount. Here are some of the key benefits of opting for electric water heaters:

High Efficiency

Electric water heaters are known for their high energy efficiency. Unlike gas water heaters, which lose heat through flue gases, electric heaters convert almost all the electrical energy into heat. This makes electric tankless water heaters, electric on demand water heaters, and electric tankless boilers excellent choices for energy-conscious homeowners.

Lower Installation Costs

The installation of electric water heaters tends to be simpler and cheaper compared to gas systems. Electric continuous water heaters and electric hot water tanks don’t require venting or gas lines, making the initial setup more affordable. This is especially true for installations of electric on demand hot water heaters and electric tankless water heaters in Canada.

Safety and Convenience

Electric water heaters are generally safer than their gas counterparts. There’s no risk of gas leaks or carbon monoxide poisoning, making them a reliable choice for many households. Additionally, options like the electric on demand water heater provide immediate hot water without the wait, enhancing convenience.

Consistent Performance in Cold Climates

For residents of the Hamilton & the Greater Toronto Area, electric water heaters offer reliable performance even during harsh winters. Electric systems are less affected by external temperatures compared to gas systems, ensuring a steady supply of hot water year-round.

Environmental Impact

Electric water heaters can be powered by renewable energy sources, reducing your carbon footprint. Integrating your electric water heater with solar panels or a community solar program can make your home more eco-friendly and lower your energy bills.

Space-Saving Designs

Many electric water heaters, such as electric tankless water heaters and electric on demand water heaters, have compact designs that save space. This is particularly beneficial for urban homes in the Greater Toronto Area where space can be limited.

Cons of Electric Water Heaters

While electric water heaters offer many benefits, they also come with some drawbacks. Understanding these cons can help you make a well-rounded decision. Below, we outline some of the key disadvantages associated with electric water heaters.

Higher Operating Costs

While electric water heaters are efficient, electricity is often more expensive than natural gas, leading to higher operating costs over time. This is a key consideration when comparing gas vs electric water heaters. Although electric systems are easier and cheaper to install, the ongoing expense of electricity can add up, making them potentially less cost-effective in the long run.

Slower Heating

Electric water heaters typically heat water more slowly than gas heaters. This can be a drawback for larger households with high hot water demands. For instance, when using an electric hot water tank, it might take longer to recover hot water after heavy usage periods, such as multiple showers in a row. This slower recovery rate means that during peak usage times, you might run out of hot water faster than you would with a gas system.

Dependence on Electricity

Electric water heaters rely entirely on electricity. In the event of a power outage, they will not function, which can be a significant inconvenience. 

Unlike gas water heaters that can continue to operate during power failures, an electric tankless water heater or an electric on demand water heater will leave you without hot water until power is restored.

Limited Placement Options

Although electric water heaters are generally easier to install, they still require access to a reliable electrical supply. This means that placing an electric water heater in certain areas of your home, such as a detached garage or an outdoor shed, might not be feasible without additional electrical work.

Environmental Impact of Electricity Source

While electric water heaters themselves do not emit greenhouse gases, the environmental impact depends on how the electricity is generated. In areas where electricity comes predominantly from fossil fuels, using an electric water heater might not be as environmentally friendly as using a propane hot water on demand system or a gas instant water heater.

Types of Electric Water Heaters

Understanding the different types of electric water heaters available can help you make an informed decision that best suits your household’s needs. Here’s an in-depth look at some popular options:

Types of Electric Water Heaters

Electric Tankless Water Heater

Tankless electric water heaters heat water on demand, providing a continuous supply without the need for a storage tank. This type of heater, often referred to as an electric instant water heater or electric on demand water heater, is perfect for households looking to save space and reduce energy consumption.

Electric Hot Water Tank

Electric hot water tanks, such as the 40 gallon hot water tank, store a large volume of hot water, ensuring it is always available when needed. These are ideal for larger households with high hot water demands.

Electric Tankless Boiler

An electric tankless boiler provides both heating and hot water, making it a versatile option for homes needing both functionalities from a single unit. This system is efficient and saves space by eliminating the need for a separate water heater and boiler.

Tankless Water Heater Canada

For Canadian homeowners, tankless water heaters are an excellent choice due to their efficiency and space-saving design. Electric tankless water heaters in Canada are especially popular due to their ability to provide instant hot water in colder climates.


In conclusion, electric water heaters offer numerous benefits, including high efficiency, safety, and lower installation costs. However, they also come with higher operating costs and slower heating times compared to gas water heaters. Understanding these pros and cons can help you make an informed decision when choosing an electric water heater for your home.
