Choosing Between a Gas or Electric Tankless Water Heater for Your Home

When it comes to upgrading your Ontario home’s water heating system, homeowners are increasingly considering tankless water heaters. Unlike traditional models that store heated water in a tank, tankless water heaters warm water as it's needed—delivering continuous hot water without bulky storage.

However, one of the most significant decisions you’ll face is whether to choose a gas or electric tankless water heater. This blog will explore the key differences between these two options to help you make an informed choice for your home.

Behind the Heat: The Science of Tankless Water Heaters

Before delving into the specifics of gas and electric options, it’s essential to understand the basic operation of tankless water heaters. These systems heat water directly as it flows through the unit, which means you have an endless supply of hot water. This efficiency can lead to lower energy bills, and a smaller carbon footprint compared to traditional water heaters.

Tankless Gas Water Heaters

Tankless gas water heaters use natural gas or propane to heat water. Here are some of the primary features and considerations associated with gas models.

Advantages of Tankless Gas Water Heaters

• Higher Flow Rate: Gas tankless units generally deliver a higher flow rate than electric models, making them ideal for larger homes with increased water usage.

• Energy Efficiency: Generally, gas heaters are more energy-efficient than electric models, especially in colder climates where electric heaters might struggle to maintain consistent temperatures.

• Lower Operating Costs: Although the initial purchase price of a tankless gas water heater may be higher, the cost of natural gas is often lower than electricity, leading to potential savings on your energy bill over time.

  
  

Disadvantages of Tankless Gas Water Heaters

• Installation Complexity: Gas units require proper venting to ensure safe operation, which can complicate installation and increase costs.

• Maintenance Requirements: Gas tankless units often require more regular maintenance, including inspections for potential gas leaks and proper ventilation performance.

• Availability of Gas Supply: If your home is not already equipped with a gas line, you may face additional costs to install one.

Tankless Electric Water Heaters

Electric tankless water heaters use electric coils to heat water. Here are their main features and considerations.

Advantages of Tankless Electric Water Heaters

• Ease of Installation: Electric models are generally easier and less expensive to install since they do not require venting. This can make them a more straightforward option for many homeowners.

• Lower Upfront Investment: Electric tankless water heaters usually cost less initially than gas models, making them a budget-friendly choice for cost-conscious homeowners.

• Compact Size: Electric units are often smaller and more compact than gas units, allowing for more flexible installation options in tight spaces.

  
  

Disadvantages of Tankless Electric Water Heaters

• Lower Flow Rate: Electric models usually have a lower flow rate than gas models, which may be a drawback for larger households or homes with multiple simultaneous hot water demands.

• Higher Operating Costs: Depending on your local electricity rates, the operating costs for electric models can be higher than for gas units, especially in areas where electricity is expensive.

• Limited Performance in Cold Climates: In colder regions, electric units may struggle to provide sufficient hot water during peak demand periods, as they can be less effective at heating water quickly.

  
  

Choosing Wisely: Factors That Make a Difference

When deciding between a gas and electric tankless water heater, consider the following factors:

• Household Size & Usage Patterns: Consider how much hot water your household uses daily. Larger families may benefit from the higher output of gas-powered units.

• Energy Source Availability: Consider what energy sources are available in your area. If you already have a gas line, a gas unit may be more convenient.

• Installation Costs: Take into account the initial setup costs and any required upgrades to your home’s systems, along with available financing options.

• Long-Term Costs: Analyze your local energy rates and calculate the long-term operating costs associated with each type of unit.

• Environmental Impact: If sustainability is a priority, consider the environmental implications of both gas and electric options.
