Instant water heater

About instant water heater

An instant water heater provides hot water on demand and is an essential requirement for every home. In the past, you needed storage for a water heater. Tankless water heaters have changed all of that. Since their tank size does not limit them, they can deliver an unlimited supply of instant hotwater. All you need is an instant hot water heater, and you can get hot water when you need it within your home.

There are many things to consider, but one of the most significant issues is deciding if you want a tankless gas water heater or a tankless electric water heater. Other issues to consider include how much hot water you need during peak hours and if your home can accommodate a whole house tankless electric water heater or gas tankless hot water heater.

How tankless water heaters work

When you open the hot water tap, cold water enters the tankless water heater. At the same time, the electric heating element (if you are using an instant electric water heater) kicks into action and heats the water. When you turn off the hot water tap, cold water stops entering the unit, and the heater goes into idle mode. If it is a gas tankless water heater, propane is the fuel for the gas burner.

This design allows for more convenience and power saving. The drawback is that tankless water heaters can cost a lot though you can save costs with a tankless electric water heater installation. However, an under-the-sink water heater is the best option if you want to reduce costs from a long-term perspective.

Gas or electric

If you are going ahead with a tankless water heater installation, decide if you want tankless natural gas water heaters or a tankless electric water heater.

Depending on your region, a gas tankless hot water heater is typically cheaper. However, if you don't mind the price and you are looking for the most energy-efficient option, an electric tankless hot water heater is the best choice for you.
