Replacing an old-style water heater with a tankless water heater is a wise move, especially for homeowners with inexpensive, energy-efficient, and compact-built homes.

Although one of its downsides is its pricey unit and installation cost, having one that you can use on-demand is more convenient. Plus, a tankless water heater doesn’t require a lot of maintenance.

A tankless water heater has many benefits over the traditional storage tank type. One advantage is that you don’t have to wait for the hot water to come out because it heats water as it passes through the unit.

This means you can shower immediately after turning on the faucet, which is very convenient, especially if you have kids who need to take a bath in the morning.

If you plan to replace your old water heater device with a tankless one, here is a list of the best tankless water heaters on the market this year.

You will also find a brief review of the unit to help you decide and choose which one meets your requirements.
