When you turn on the tap, cold water travels through a pipe into the unit where either a gas burner or an electric element heats the water instantly. This process ensures you have a continuous supply of hot water without the energy waste of maintaining a tank.

How does a tankless water heater work?

A tankless water heater operates by heating water directly without the need for a storage tank. Here is a detailed look at the process:

  • Activation: When a hot water tap is turned on, cold water enters the heater through a pipe.
  • Heating: A flow sensor detects the water flow and activates either a gas burner or an electric element.
  • Heat exchange: The water passes through a heat exchanger where it absorbs heat from the burner or element.
  • Delivery: The heated water is then delivered directly to the tap, ensuring a continuous supply of hot water.

This process ensures that hot water is available on demand, improving energy efficiency and eliminating the need for a bulky storage tank. For those needing larger storage options, consider a 50 litre water geyser.
