Review of Rheem RTGH-95XLN Prestige Natural Gas Outdoor Tankless 9.5 GPM

Nobody wants to spend all of their money on the energy bill, and it certainly feels that way when you have a traditional water heater system with a tank. For some time now, people have started to install tankless water heaters in their homes, and you should keep reading for the details.

What’s behind the popularity of tankless water heaters?

As the name suggests, the tankless water heaters have no tank and give hot water on demand. There is no tank to collect the water and no energy consumed for keeping it hot. Having said that, it’s evident that tankless water heaters use less energy and cut down the energy bill right away. Even if you choose a more expensive model and pay for professional installation, a tankless water heater is more energy-efficient and cheaper than the traditional systems with tanks.

Not having a tank brings another benefit: water doesn’t get to stay in the system. Basically, the water doesn’t have the time to cause corrosion or damage to the elements of the system. The low risk for corrosion of tankless water heaters also makes them more durable. However, you should be cautious about the hardness of the water in your area. Even if it’s not high, it’s better that you also use a water softener along with the tankless water heater.

Taking a look at a tankless water heater is going to reveal another advantage. The overwhelming majority of tankless water heaters are small and compact, requiring only a little space for the mount. Some models need even 1/3 of the area that you needed a conventional water heater with a tank.

Many modern models come with smart features (Wi-Fi feature), whereas the installation is a DIY project nine times out of ten. Once again, you should be cautious and check the user manual. In some cases, not installing the unit by a licensed professional plumber will void the warranty.

The price of some models and the installation costs can make you doubt the tankless water heaters. Regardless of the issues, the tankless water heaters are always a safe buy.
