Tankless Water Heater Buyer’s Guide

Selecting the right tankless water heater for your home can seem overwhelming with numerous options available in the Canadian market. This buyer’s guide will help you navigate the essential factors to consider, ensuring you choose the perfect tankless water heater for your needs.

1. Types of Tankless Water Heaters

There are two primary types of tankless water heaters: electric and gas (natural gas or propane). Each type has its advantages and disadvantages:

a) Electric Tankless Water Heaters:

• Generally less expensive to purchase and install
• More energy-efficient
• Lower maintenance requirements
• Suitable for homes with no natural gas line

b) Gas Tankless Water Heaters:

• Higher hot water output
• Faster heating
• Suitable for larger households
• Can work during power outages if equipped with a battery backup

2. Size and Flow Rate

Determine the appropriate size and flow rate (measured in gallons per minute, or GPM) for your tankless water heater by considering your household’s hot water usage. Calculate the total GPM of all hot water appliances that may be running simultaneously. Choose a tankless water heater with a GPM rating that meets or exceeds your calculated demand.

3. Energy Efficiency

One of the key benefits of tankless water heaters is their energy efficiency. Look for models with a high energy factor (EF) rating, which measures the efficiency of the unit. Electric tankless water heaters generally have a higher EF rating than gas models. Additionally, gas models with an ENERGY STAR certification offer more energy-efficient performance.

4. Installation Requirements

The installation requirements for tankless water heaters vary depending on the type and model. Electric models typically have simpler installation requirements, while gas models may require venting and gas line adjustments. Consult a professional installer for an accurate assessment of the installation costs and requirements.

5. Climate Considerations

In colder Canadian climates, the incoming water temperature is lower, which may affect the performance of a tankless water heater. Ensure the model you choose is capable of handling the temperature fluctuations in your region.

6. Warranty and Maintenance

Choose a tankless water heater with a comprehensive warranty that covers the heat exchanger, parts, and labor. Regular maintenance is essential to ensure the optimal performance and longevity of your system. Gas tankless water heaters generally require more frequent maintenance than electric models.

7. Budget

Tankless water heaters can vary significantly in price, with electric models generally being more affordable than gas models. Consider both the upfront costs (purchase and installation) and long-term operating costs when determining your budget.

FAQ

1. What is a tankless water heater?

A tankless water heater, also known as an on-demand or instantaneous water heater, heats water only when it’s needed. This eliminates the need for a storage tank and reduces energy consumption, providing a more energy-efficient and environmentally friendly option compared to traditional tank water heaters.

2. How do tankless water heaters work?

Tankless water heaters use either electric elements or gas burners to heat water as it flows through the unit. When a hot water tap is turned on, cold water enters the heater, and the heating elements or burners activate, rapidly heating the water to the desired temperature. The hot water is then supplied to the tap, providing a continuous flow of hot water.

3. Are tankless water heaters more energy-efficient than traditional tank water heaters?

Yes, tankless water heaters are generally more energy-efficient than traditional tank water heaters because they only heat water when it’s needed. This eliminates standby heat loss associated with storing hot water in a tank. Electric tankless water heaters are often more energy-efficient than gas models.

4. What is the average lifespan of a tankless water heater?

The average lifespan of a tankless water heater is around 20 years, which is longer than the average lifespan of a traditional tank water heater, which is typically 10-15 years. Regular maintenance and proper installation can further extend the lifespan of a tankless water heater.

5. Can a tankless water heater provide enough hot water for my entire home?

The ability of a tankless water heater to supply enough hot water for your entire home depends on the unit’s size and flow rate. Choose a tankless water heater with a GPM rating that meets or exceeds the total hot water demand of all your appliances running simultaneously.

6. Can I install a tankless water heater myself?

While some homeowners may feel comfortable installing an electric tankless water heater, it’s generally recommended to hire a professional for the installation. This ensures proper installation and adherence to local building codes and safety regulations. Gas tankless water heaters, in particular, require professional installation due to the complexities of venting and gas line adjustments.

7. Are tankless water heaters suitable for cold Canadian climates?

Yes, tankless water heaters can be suitable for cold Canadian climates. However, it’s essential to choose a model designed to handle temperature fluctuations and low incoming water temperatures in your region. Gas tankless water heaters often perform better in colder climates due to their higher heating capacity.

8. How often do tankless water heaters need maintenance?

The maintenance frequency for tankless water heaters depends on the type and model. Electric tankless water heaters generally require less maintenance than gas models. It’s recommended to have your tankless water heater inspected and serviced by a professional at least once a year to ensure optimal performance and longevity.

9. Do tankless water heaters save money?

Tankless water heaters can save you money on your energy bills due to their increased energy efficiency. The actual savings depend on factors such as your hot water usage, energy rates, and the efficiency of your previous water heater. While the upfront cost of a tankless water heater may be higher than a traditional tank water heater, the long-term savings and extended lifespan can offset the initial investment.

Conclusion

The best tankless water heaters in Canada provide energy-efficient performance, endless hot water, and a compact design. Whether you choose an electric or propane model, these units can save you money on your energy bills and offer a more environmentally friendly option compared to traditional tank water heaters.

By considering the features, specifications, and customer reviews of these top-rated tankless water heaters, you can make an informed decision that best suits your household’s needs. Keep in mind factors such as the size of your home, the number of people using hot water, and whether you require a portable option for outdoor use. With the right tankless water heater, you can enjoy the comfort of endless hot water while saving energy and space in your home.
