How do tankless water heaters work? 

Tankless water heaters don’t store water like tank-style heaters do. Instead, they heat the water when you open the tap and stop heating it when you turn it off again. This gives you unlimited hot water while using less energy at the same time.

While the amount of hot water is unlimited, because tankless systems have a fixed flow rate of up to 11.0 gallons (42 litres) per minute, running multiple faucets, showers or appliances at the same time can lower the overall water pressure.1

How a tankless water heater works

Benefits of tankless water heaters 

Tankless water heaters provide hot water at a rate of up to 11.0 gallons (42 litres) per minute.  They also use less energy, last longer, and take up less space than standard tank heaters. These discrete and compact units give you and your family the benefits of:

Convenience

Run the dishwasher and washing machine and take a shower at the same time without losing pressure or running out of hot water.1

Comfort

Enjoy a continuous supply of hot water – when and where you need it.

Safety

Set the water temperature exactly where you want it with the touch of a button. Tankless models also reduce the risk of water heater leaks.

Flexibility

Place your tankless water heater in almost any room – they’re typically no bigger than a carry-on suitcase.

Efficiency

Reduce your energy consumption by eliminating the need to continuously heat standing water.

Flexibility

Lower your energy consumption by only heating water when you need it.

Is a tankless water heater right for me?

Our Enercare Energy Management Consultants can perform a comprehensive evaluation of your home, water systems and family needs to determine the right water heating system for your family. Not every home is equipped to handle tankless systems, and retrofits to accommodate them could be expensive. Here are some facts about tankless and standard water heaters to help with the decision:

What else to consider before installing a tankless water heater

Do you live in a hard water area?

Hard water can cause a buildup of scale inside your water heater, which can cause your unit to lose efficiency. If you’re in a hard water area, you may want to consider installing a water softener as well.

How many people live in your home?

Tankless water heaters supply almost limitless hot water2, but the pressure may not keep up with demand if everyone needs it at the same time. Be sure to consider how much hot water you need in periods of high demand.

Do you live in a high-rise condo?

Some tankless water heaters require modifications to the exhaust system on the outside of your building – something your condo board may not allow or that would not comply with building regulations.
