Rheem RTGH-95DVLN Features


Advanced Tankless Technology

When it comes to advanced features, this Rheem tankless water heater has quite a few. First of all, it comes with a hot-start programming feature which reduces fluctuation in the water temperature. Then, it also has a safety Overheat Film Wrap (OFW) which provides protection in case of a breach of the heat exchanger. The EZ-Link cable technology allows the owners to connect two tankless water heaters that will operate as one. In addition, this water heater is also a low-NOx model.

Venting and Self-Diagnostic System

In addition, this unit comes with a self-diagnostic system which constantly keeps the heater’s functions on check. If a problem arises, for example with venting or in the gas supply lines, the system will warn the user. This feature adds to the safety of the unit since it is very likely to prevent any accidents.

High Flow Rate

This Rheem tankless water heater has a very high flow rate of 9.5 GPM. This number exceeds the flow rate of many electric water heaters and is enough to heat three full-flow showers at once. Even at times of peak usage, this water heater will make sure that you never run out of hot water, even if your home has three or more bathrooms.

Energy-Efficient Tankless Water Heater

The Rheem RTGH-95DVLN is Energy Star approved and its system has a 0.94 energy factor. This exemplifies how energy-efficient the product is and helps the buyer estimate how much power it may consume. The body of this unit is made out of stainless steel, ensuring that the main tank doesn’t get affected by any outside factors.

Since this Rheem tankless water heater is a condensing unit, it also extracts heat from exhaust gases, making it more energy-efficient than the non-condensing models.
