How Does A Tankless Water Heater Work?
Tankless water heaters operate on-demand, heating water only when it is needed. When a hot water tap is turned on, cold water flows through a heat exchanger, where it is rapidly heated by a gas burner or electric element. This process ensures a continuous and instantaneous supply of hot water, eliminating the need for a storage tank.
A tankless water heater looks very different from the traditional hot water tank we’re all used to. Instead of a large cylindrical tank, you’ll see a compact box, usually mounted on the wall, with a network of pipes and valves attached. Here’s a quick look at how a tankless heater works:
- Turning on a fixture (shower or hot water faucet) activates water flow into the heater.
- This activates the flow sensor, which in turn triggers the control panel.
- The control panel switches on the fan.
- The fan has several essential functions: drawing in air from outside, opening the gas valve, and igniting the gas burner.
- Exhaust gases from the combustion are vented outdoors, through either an exterior wall or the roof.
- The gas burner produces heat, which the heat exchanger transfers to the incoming water.
- The mixing valve tempers the water — which is now superheated — to avoid scalding.
- The water is piped to your shower or faucet.
- You enjoy a continuous flow of hot water for as long as you like.
- When the fixture is turned off, the flow of hot water ends and the gas burner shuts down.
Why Install A Tankless Water Heater?
Glad you asked! There are tons of benefits to installing a tankless water heater.
Energy Efficient
The best tankless water heaters are highly energy efficient because they only heat water as it is needed. This eliminates the standby energy losses associated with traditional storage tank water heaters, resulting in lower utility bills.
Energy efficiency is what frequently motivates people to switch to a natural gas or electric tankless water heater. Conventional tank water heaters are one of the highest residential energy sources, second only to heating and cooling systems. That’s because they waste an awful lot of energy keeping a huge tankful of water hot 24/7, whether it’s needed or not.
Tankless water heaters, by contrast, heat only as much water as you need when you need it. They do not store hot water for future use. The happy result? Throughout its lifetime, a tankless water heater can save you thousands of dollars on your natural gas or electricity bills.
A great choice for energy savings: Water heaters that have earned certification by the Energy Star energy-efficient appliance program.
More Hot Water
Imagine never again being stuck with a cold shower because your kids have used up all the hot water! That’s what you can expect when you switch to a tankless water heater. Aptly described as providing “hot water on demand,” this appliance will continue heating water as long as you need it.
With a tankless water heater, you’ll never run out of hot water. Unlike storage tank heaters, which have a limited supply, tankless units provide a continuous flow of hot water for as long as you need it.
Saves Space
Tankless water heaters are compact and wall-mounted, saving valuable floor space. They can be installed in smaller utility closets, under sinks, or even outdoors, making them an ideal choice for homes with limited space.
Approximately the size of a suitcase, tankless water heaters have a trim profile and fit easily into a small space such as a closet, as long as they’re properly vented. This frees up floor space — especially important when you live in a small house, a townhome, or a condo.
Longer Life Span
Tankless water heaters have a longer lifespan compared to traditional storage tank heaters. With proper maintenance, they can provide reliable hot water for two decades or more.
Tankless water heaters last longer since they don’t experience all the wear and tear that results from storing a large volume of heated water. Typically, the life span of a tankless water heater will be 20 years or more, compared to an average of 8-12 years for a hot water tank.
Less Chance of Flooding
Since tankless water heaters do not have a storage tank, there is no risk of catastrophic tank failure and subsequent flooding. This reduces the potential for water damage to your home. Your risk of catastrophic water heater flooding and water damage to your basement is greatly reduced when you opt for a tankless water heater. Tankless heaters don’t store large quantities of water (hot water tanks hold about 150-300 litres!). So even if they develop a water heater leak — usually when they reach an advanced age and are due for replacement — it will be a much smaller volume. Adding a drain pan to your tankless water heater installation will fully contain any future leakage.
How Long Do Tankless Heaters Last?
The best tankless water heaters are known for their durability and longevity. On average, a well-maintained tankless unit can last up to 20 years or more. Regular maintenance, such as flushing the system and checking for mineral buildup, can significantly extend the lifespan of your tankless water heater.
Tankless water heaters are renowned for their durability and longevity, making them a reliable and cost-effective choice for homeowners. On average, a well-maintained tankless water heater can last up to 20 years or more. This lifespan is considerably longer compared to conventional water heaters, which typically have a lifespan of around 10-15 years.

What Is The Flow Rate Of A Tankless Unit?
The flow rate of a tankless water heater refers to the amount of hot water it can deliver per minute. It is measured in gallons per minute (GPM). When choosing an electric or gas tankless water heater, consider the number of fixtures and appliances that will be using hot water simultaneously. This will help determine the appropriate flow rate for your household’s needs.
