What Are the Tankless Water Heaters? 

Tankless water heaters, also known as on-demand or instantaneous water heaters, are gaining popularity among Canadian homeowners for their numerous benefits, including energy efficiency, cost savings, and space-saving design. In this blog, we will explore the advantages of tankless water heaters, explain how they work, and provide expert guidance on selecting the ideal system for your home.

Advantages of Tankless Water Heaters

Energy Efficiency

One of the primary benefits of tankless water heaters is their energy efficiency. Traditional storage tank water heaters constantly expend energy to maintain the temperature of stored water, resulting in standby heat loss. In contrast, tankless water heaters only heat the water when needed, significantly reducing energy consumption and saving you money on energy bills.

Space-Saving Design

Traditional water heaters require a significant amount of space for the storage tank. Tankless water heaters, however, do not require a tank and have a compact design that can be easily mounted on walls, freeing up valuable floor space in your home.

Endless Hot Water Supply

Since tankless water heaters heat water on demand, you will never run out of hot water during peak usage. This continuous hot water supply ensures all household members a comfortable and convenient experience.

Longer Lifespan

Tankless water heaters typically have a longer lifespan than traditional storage tank water heaters, making them a more cost-effective choice. With proper installation and maintenance, tankless water heaters can last up to 20 years.

How Tankless Water Heaters Work

Tankless water heaters use either gas or electricity to heat water on demand instead of storing it in a tank. When you turn on a hot water tap, cold water travels through a pipe and into the unit. In gas-powered systems, a gas burner heats the water, while electric models use an electric element to heat the water.

As the water flows through the heat exchanger, it quickly reaches the desired temperature and is delivered to the tap. The unit shuts down once the hot water tap is turned off, and energy consumption stops, ensuring maximum efficiency.

Selecting the Ideal Tankless Water Heater for Your Home

Determine Fuel Type

Choose between a gas-powered or electric tankless water heater based on your home’s energy sources. Gas-powered units often have a higher flow rate and capacity, while electric models are typically more energy efficient and easier to install.

Calculate Flow Rate and Temperature Rise

When selecting a tankless water heater, it’s essential to consider the flow rate (measured in gallons per minute or GPM) and the temperature rise required for your home. Flow rate represents the amount of hot water the unit can produce. At the same time, the temperature rise refers to the difference between the incoming cold water temperature and the desired hot water temperature. Consult a heating and cooling professional, like Furnace King, to help you determine your home’s specific requirements.

Check Energy Efficiency Ratings

Look for energy-efficient tankless water heaters with ratings of high Energy Factor (EF) or Uniform Energy Factor (UEF). These ratings indicate the unit’s overall efficiency in converting energy into hot water. Higher ratings result in more energy and cost savings.

Consider Installation and Maintenance

When selecting a tankless water heater, it’s crucial to factor in installation and maintenance requirements. Professional installation by a reputable company like Furnace King ensures that your tankless water heater functions optimally and efficiently. Regular maintenance, such as annual inspections and sediment flushing, is crucial for maintaining system performance and longevity.


Investing in a tankless water heater is wise for Canadian homeowners seeking an energy-efficient and eco-friendly solution for their hot water needs. The numerous benefits of tankless water heaters, such as energy savings, compact design, and endless hot water, make them an attractive option for upgrading your home’s water system.
