How to Choose the Right Tankless Water Heater for Your Home in Canada
When it comes to comfort and convenience in Canadian homes, having a reliable supply of hot water is non-negotiable. Whether you’re dealing with frigid winters in Alberta or the coastal chill of British Columbia, hot water plays a central role in everyday life — from bathing to washing dishes to doing laundry. Choosing a tankless water heater for your home in Canada is not only a step toward energy efficiency but also a move that can provide long-term savings and consistent performance.
But how do you choose the right model? With so many options on the market and a variety of features to consider, it’s easy to feel overwhelmed. This comprehensive guide breaks down the key factors that matter most when selecting a tankless water heater tailored for Canadian homes.
Understand How Tankless Water Heaters Work
Before diving into the selection process, it's important to understand how a tankless water heater operates. Instead of storing hot water, it heats water on demand. When you turn on a hot water tap, cold water flows through a heating element—either electric or gas-powered—and is heated instantly. This results in an endless supply of hot water as long as the system's capacity isn't exceeded.
Evaluate Your Household’s Hot Water Demand
A major factor in choosing tankless water heaters in Canada is understanding your household’s water usage. The number of people in your home, as well as how and when hot water is used, will influence the size and type you need.
Start by making a list of all appliances and fixtures that use hot water—showers, bathtubs, dishwashers, laundry machines, and sinks. Consider how many might be used simultaneously. In Canada, where winters require hotter water temperatures, you’ll want to factor in extra heating capacity.
Here are some common hot water flow rates converted to gallons per minute (GPM):
- A shower typically uses between 1.8 to 2.6 GPM.
- A dishwasher generally requires 1.1 to 1.6 GPM.
- A washing machine can use about 1.8 to 2.4 GPM.
- A kitchen sink usually runs between 0.8 to 1.3 GPM.
Add up the flow rates of the appliances that might be used at the same time to determine the required flow rate for your water heater.
Determine the Right Size for Canadian Conditions
Sizing is critical when selecting a tankless water heater. In Canada, where groundwater temperatures can fall to near freezing, the heater must work harder to bring the water up to the desired temperature.
To ensure you choose the correct size, you need to calculate the temperature rise — the difference between incoming cold water and your desired hot water temperature (typically around 122°F or 50°C to 131°F or 55°C).
For example, if your incoming water temperature is 41°F (5°C) and you want it at 122°F (50°C), you’ll need a rise of 81°F (45°C). Combine this with the total GPM you calculated above to find the capacity required.
Brands like Eccotemp tankless water heaters often offer sizing charts specific to Canadian conditions, helping you match your needs with the right model.
Choose Between Gas and Electric Models
Both electric and gas-powered tankless water heaters have their place in Canadian homes. Your choice depends on your location, energy source availability, and installation preferences.
Electric models (check our Indepth guide about Electric Tankless Water Heaters here)a re ideal for smaller homes, condos, or cottages. They are easier and often cheaper to install but require sufficient amperage and may need panel upgrades.
Propane or natural gas models are better for larger households or homes with multiple bathrooms. They can produce higher flow rates but require proper ventilation and gas line setup.
Eccotemp, for example, offers both propane and natural gas options that are popular for Canadian homes, especially in off-grid or rural areas.
Consider Energy Efficiency and Certifications
In a country where heating costs can soar during the colder months, energy efficiency is a top priority. Look for models that has CSA certification, which indicates compliance with rigorous Canadian safety and performance standards.
Efficiency is typically measured by the Energy Factor (EF) or Uniform Energy Factor (UEF). The higher the rating, the more efficient the water heater.
Some Eccotemp tankless water heaters offer high UEF ratings and eco-mode settings, making them well-suited for eco-conscious homeowners in Canada.
Think About Installation Requirements
Installation varies depending on the size, fuel type, and model you choose. Gas models require ventilation through an exterior wall or roof and may also need larger gas lines or adjustments to existing plumbing.
Electric models, on the other hand, typically require a significant amount of amperage. It's important to consult with a licensed professional to assess whether your home’s electrical panel can support the demand.
Look for Smart Features and Remote Monitoring
Modern water heaters aren’t just about hot water—they can also include features that enhance convenience and efficiency. Some Eccotemp tankless water heaters offer smart home integration, and remote monitoring, allowing you to manage your system via a mobile app.
These features are especially helpful in seasonal or vacation properties where remote access can prevent problems before they arise.
Durability and Weather Resistance
Canadian winters can be extremely harsh, which is why Eccotemp Indoor Tankless Water Heaters come with built-in freeze protection. When choosing a model, prioritize weather-resistant options that are CSA-certified and specifically rated for performance in cold climates.
Budgeting for Your Tankless Water Heater
The price of a tankless water heater varies based on capacity, energy source, and extra features. While upfront costs might be higher than other water heating solutions, the long-term energy savings, reduced maintenance, and increased lifespan often justify the investment.
Consider the following in your budget: the purchase price, installation costs, potential panel or gas line upgrades, annual maintenance. Some provinces, like British Columbia or Ontario, may offer rebates for choosing CSA-certified models.
Brand Reputation and Customer Support
Choosing a trusted brand with a strong track record in Canada can make all the difference in performance and peace of mind. Eccotemp tankless water heaters are known for reliability, ease of use, and solid customer support across North America.
Before purchasing, check online reviews, warranty details, and customer service accessibility. A good warranty, typically five to ten years for the heat exchanger and one to three years for other parts, is a sign of a manufacturer that stands behind its products.
Final Thoughts
Choosing a tankless water heater in Canada involves more than just picking the model with the highest flow rate or sleekest design. It’s about matching your household’s specific needs to a system that performs efficiently year-round—even through sub-zero temperatures.
From calculating flow rates and temperature rise to evaluating installation logistics and smart features, taking the time to plan your purchase can ensure years of reliable hot water.
