Havells Instanio 3-Ltr Instant Geyser White And Blue

An instant geyser, also known as a tankless or on-demand water heater, is a type of water heating system that heats water as it flows through the unit, rather than storing hot water in a tank.

When a hot water tap is turned on, cold water flows into the unit and is rapidly heated by a gas burner or electric heating element. The hot water is then delivered directly to the faucet, showerhead, or appliance that called for it.

One of the advantages of an instant geyser is that it provides hot water on demand, so you don't have to wait for a tank to fill up before you can use hot water. It also saves energy because it doesn't need to continuously heat water in a tank, which can result in standby heat loss. However, it may require higher upfront costs than traditional tank water heaters and may have limitations in supplying hot water to multiple fixtures at the same time.
