What is an instant water heater?

The instant water heater is a type of water heater that heats water in real-time. It only heats the water that passes through it at that moment. There is no hot water storage tank. This has many advantages, such as energy savings, since only the water being used is heated, and longer lifespan, as there is no water tank and no accumulation of salts on the resistance and other components.

It operates with electricity and is single-phase.

How It Works

The instant water heater has an inlet pipe for cold water, which passes through the resistance, heats up, and exits through the hot water outlet pipe. A necessary condition for the instant water heater to initially operate is the inlet cold water pressure should not be too low.

The water temperature is regulated by a thermostat so that it does not exceed a maximum value. The temperatures that the hot water reaches are pre-set so that one can use the hot water directly, without needing to mix it with cold water.

The maximum temperature that can be reached for hot water production is 55 °C, while the maximum water flow rate reaches up to 2.2 liters per minute. Indicatively, 38-42 °C degrees are standard for shower use.

Advantages of instant water heaters compared to traditional electric water heaters

  • It is small in size and does not take up much space.
  • There are no energy losses, as only the water being used at that moment is heated. Therefore, we save on the electricity bill. In a traditional water heater, the hot water that is not used goes to waste.
  • The hot water used in the instant water heater is used as is, without mixing with cold, as happens in a traditional water heater. Thus, we also save water, in addition to electricity.
  • There is no need to wait for the water to heat up. As soon as we turn on the tap, hot water flows in a few seconds. The traditional water heater takes a few minutes, depending on its size.
  • The hot water never runs out. As long as we have the tap open, we will have hot water.
