How does it work??

In simple terms, the process behind a tank-less water heater’s working is as follows:

  • Water passes through coils which heat the water.
  • The burner which heats the coils is ignited by a sensor.
  • The water is instantly heated as it passes through the coils.
  • The heater shuts down as soon as it detects that there is no water flow.

There are two types of tank-less systems – Limited use system and Extensive use systems.

Limited use systems heat water only for a few outlets. A good example would be your kitchen sink or a faucet. A kitchen sink requires a limited amount of water used at intervals. It does not require a continuous flow of water. Lag-time is a common problem with tank-less water heaters. It is the amount of time taken by the hot water takes to reach the outlet. In large houses, the lag-time is considerably long, sometimes up to a few minutes.
Extensive use systems are much larger and can supply hot water to multiple outlets.
