How Point-of-Use Water Heaters Work

In the case of the tankless point of use heater, the water is heated as the water passes through it towards the tap.
These heaters are called point-of-use because they are fitted under the sink or close to the plumbing fixture.
Since it is tankless, no water is retained inside the tank, making this a more energy-efficient option.
