Gas vs. Electric Tankless Water Heaters: Choosing the Right Option for Ontario Homes

tankless water heater

Deciding between a gas and electric water heater can feel like diving into a maze of options. After all, they both have one job: heating water! So, how do you choose the right one for your home?

With Ontario's unpredictable weather, a dependable and efficient hot water supply is necessary for year-round comfort. At Don's Heating & Cooling, we understand the importance of this decision. Tankless water heaters offer space-saving benefits and potential energy savings, but with two primary fuel sources, gas and electric, making the right choice requires careful consideration.

Let’s unravel the complexities and break down the key factors to help you decide between a gas tankless water heater and an electric tankless water heater.


The Efficiency Edge: Gas Tankless Water Heaters

Ontario winters can be harsh, and having a consistent supply of hot water is crucial. Gas tankless water heaters are an excellent option in this regard. They use natural gas or propane to heat water instantly as soon as you turn on the faucet. This eliminates standby heat loss, which is a common issue with traditional storage tank water heaters that constantly reheat stored water.

Natural gas prices in Ontario are generally stable compared to electricity, making gas tankless water heaters a potentially cost-effective option in the long run, especially for larger households with high hot water usage.


Installation Considerations: Venting and Gas Lines

Although gas tankless water heaters are very efficient, they require proper venting to get rid of combustion gases. It is important to note that the venting systems from your previous water heater may not be compatible with the new one, and installation may require extra work. Also, a gas line connection is necessary, and depending on your home's existing setup, upgrades might be required.


Electric Tankless Water Heaters: Environmentally Friendly and Space-Saving

Homeowners who prioritize eco-friendliness can opt for electric tankless water heaters, which offer a compelling solution. These heaters don't generate any harmful emissions and can potentially integrate with renewable energy sources like solar panels. Besides, electric tankless water heaters are compact and can be wall-mounted, freeing up valuable floor space typically occupied by traditional tank heaters.


Considering Your Electrical Service

Electric tankless water heaters need a substantial electrical service upgrade to work properly. To power most units, you will need a 240-volt circuit, which may not be easily accessible in older homes. Therefore, when thinking about installing an electric tankless water heater, it's essential to consider the possible cost of upgrading your electrical service.



The Ontario government offers rebates for energy-efficient water heaters, including certain tankless models. Research available rebates before making your final decision to maximize your cost savings.
