Tankless water heaters, which are also known by the name instantaneous or demand-type water heaters, give hot water if it is needed. They are a good option to save money because they don’t have the standby loss in the energy that is associated with the storage water heater type.

This article will help you to know all there’s about this appliance, ranging from how they work, benefits, and the criteria to consider when buying the right model.

How does a tankless water heater work?

The working of this appliance might seem the opposite of the tank-style water heater because the tankless type heats the water directly with no need for a storage tank. When the tap for hot water is opened, cold water enters the unit through the pipe. Now the unit uses either an electric element or a gas burner to heat the water. Due to this, the delivery of a continuous supply of hot water is possible. The only limitation for the output of hot water is the flow rate.

Benefits of a Tankless Water Heater

Instant Hot Water

One of the noteworthy benefits of this appliance is that any source of water can be converted into hot water on demand. Unlike the conventional tank-style water heater, which is limited in the hot water supply according to the amount of storage in the tank, that is not the issue here. This tankless water heater will easily meet an endless supply of hot water to meet your lifestyle demands.

Lower Energy Bills

Since the units are designed to be highly efficient, heating only when it is required, they help to save about 40% of the energy costs.

Longevity

It can last for more than 20 years, which is twice the longevity of tank-style heaters.

Space Savings

Traditional water heaters require a lot of floor space, whereas the tankless water heaters come in a size of a carry-on suitcase that enables it to be installed anywhere inside or outside the house.

Clean Water

The conventional type has rust and scales built up inside the tank in which hot water is stored. Since no tank is present in a tankless water heater, you will always experience fresh and clean water because it is not stored.
