Also called demand-type or on-demand water heaters, tankless water heaters can be extremely useful for households. One big reason is that they don’t cause standby energy losses, which is a common issue with tank water heaters. Besides this, they provide hot water only when needed. With such features, you can save big on your energy bills.

Water is heated instantaneously in tankless water heaters without the need for a storage tank. When you turn on the hot water knob, water flows through the unit’s heat exchanger. The burner inside it heats the water, resulting in a constant supply of hot water. With a tankless water heater, you won’t have to wait for water to fill up in the storage tank.

There are several things you’d want to consider to get the right tankless water heater. Here we’ve listed some of them:

1. Flow rate

The flow rate of a tankless water heater is the amount of hot water it can produce per minute. It’s important that you choose a unit with an appropriate flow rate. This will allow the water heater to meet the hot water demands of your household.

A higher flow rate is needed for larger households or homes with multiple bathrooms. A water heater with a lower flow rate is sufficient for smaller households with fewer hot water needs.

3. Efficiency

Energy Factor or EF is the unit of measurement for determining the efficiency of a tankless water heater. The higher the EF, the more energy-efficient the unit would be.

5. Warranty
