Review of Rheem 240V 2 Heating Chambers RTEX-18 Residential Tankless Water Heater

When you got tired of paying too much on your energy bill, it’s time to take a look at the alternatives. Even though the traditional water heating systems with tanks come with many benefits, they’re still expensive and not energy-efficient. Let’s not forget about the impact on the environment, either.

Why should you install a tankless water heater in your home?

With people getting more and more interested in protecting the environment, it was no surprise to anyone when new water heating systems appeared on the market. Tankless water heaters are the perfect example of how you can have hot water with a lot less energy and gallons of water in a year.

The most significant benefit of tankless water heating systems is that they only give hot water on demand. It’s why they use less energy (whether that is gas or electric). There’s no tank to collect the water, and the system doesn’t use any power to keep the water hot. On the other hand, you don’t have to take care of any tank. Tankless water heaters present a lower risk for corrosion and have minimal maintenance demands. Most of the time, flushing once a year and installing a water softener may be more than enough.

Another essential advantage to highlight is the space they need. Most tankless water heaters are compact and small, taking only 1/3 of the area that a 10-gallon tank would need.

Energy-efficient, easy to take care of, and to provide excellent storage space, it’s only natural that people are switching from traditional systems with tanks to the tankless water heaters. What you’re waiting for?
