How tankless water heaters work
When it comes to hot water supply in our homes, tankless water heaters are gaining popularity for their efficiency and continuous hot water supply. But have you ever wondered how tankless water heaters actually work? Let’s dive into the details.
Efficiency of tankless water heaters
Tankless water heaters, also known as on-demand water heaters, are designed to heat water directly without the need for a storage tank. This design eliminates the standby energy losses that occur with traditional water heaters, making tankless water heaters more efficient.
Key point: Tankless water heaters are more efficient due to the absence of standby energy losses.
Unlike conventional water heaters that constantly heat and store a large amount of water in a tank, tankless water heaters heat water as it passes through the heating elements. This means that the hot water supply is not limited by the capacity of a tank, ensuring a continuous flow of hot water whenever you need it.
Continuous hot water supply
Key point: Tankless water heaters provide a continuous hot water supply.
When you turn on a hot water tap, cold water enters the tankless water heater and flows through a heat exchanger. This heat exchanger is activated by either a gas burner or an electric element, depending on the type of tankless water heater.
The heat exchanger rapidly heats the cold water as it passes through, delivering hot water to your taps or showers in a matter of seconds. Since tankless water heaters do not store hot water, there is no risk of running out of hot water if you use it for an extended period.
Fact: Tankless water heaters can provide a continuous hot water supply, making them ideal for large families or homes with high hot water demand.
With their efficient design and continuous hot water supply, tankless water heaters offer a convenient and energy-saving solution for your hot water needs. Whether you have a small or large household, a tankless water heater can provide reliable hot water whenever you need it.
Do tankless water heaters run out of hot water
No, tankless water heaters do not run out of hot water in the way traditional tank heaters do. Tankless water heaters, also known as on-demand water heaters, heat water directly without the use of a storage tank.
When a hot water tap is turned on, cold water travels through a pipe into the unit, and either a gas burner or an electric element heats the water. As long as there is a supply of cold water and energy to heat it, a tankless water heater can provide a continuous flow of hot water.
However, their output limits the flow rate of hot water. This means that if you use hot water for multiple purposes at the same time (like showering and running the dishwasher), the heater might not keep up, leading to a decrease in water temperature.
