Tankless Water Heaters – Why You Must Install a Tankless Unit

Tankless water heaters heat water directly without using a storage tank like traditional units. Also known as on-need, instantaneous, moment-on water heater, this kind of unit immediately boil water while it is flowing by the heating device to the plumbing system and faucet. This is a big advantage over the traditional units because the energy used to heat and re-heat water in a traditional unit is saved. Because a tankless unit only heats water when you need it, you get an endless source of hot water, while also saving money on energy costs by not heating and re-heating the same tank of water.

Tankless Water Heater course of action – What Happens When You Boil Water With a Tankless Unit

When you turn on a hot water faucet in the bathroom, kitchen, toilet, laundry or any part of the house, the tankless water heater recognizes the need for hot water and starts the heating course of action. The system determines the desired output temperature as water circulates by the appliance’s heat exchanger, providing continuous hot water. When the hot water faucet is turned off or an appliance such as a dish washer is stopped, the tankless unit shuts down and goes into an energy-saving standby mode until any hot water faucet or appliance is turned on and the time of action begins all over again.


There are electric and gas tankless water heater types. While an electric tankless unit uses an electric component to heat water. A gas tankless kind use a gas burner to heat water.
