Specifications

Rheem gas tankless water heater reviews

The unit's dimensions are 18.5 x 9.8 x 27.5 inches and weighs 82 pounds. It is designed for indoor use and boasts a 0.94 energy factor.

It has electronic ignition, runs on natural gas and features a 3/4 inch gas connection, as well as a 3/4 inch water connection.

The minimum water flow that will activate the water heater is 0.40 gallons per minute. Having said that, with this model, Rheem has introduced an unprecedented minimum flow rate of 0.26 GPM (following activation).

This heater will cover the 85° C - 140°C temperature range.  As for gas consumption, it will spend up to 199,900 BTU/h.

Features

First of all, this indoor, direct vent natural gas unit comes from a manufacturer renowned across the globe. It is built sturdily and made of stainless steel which minimizes any risk of rust, corrosion or damage over time. Its vents are also made of high-quality stainless steel.

Energy Efficiency

This Rheem model is a condensing unit. Such a water heating option is considered to operate with the most energy efficiency. But what does that mean in practice? Simply put, it means that this unit generates heat via its stainless steel condensing heat exchanger. This system provides 94% energy efficiency. On the other hand, models that do not utilize it cannot provide more than 80-85% energy efficiency.

Water Flow Rate

With such a heating system, the unit is capable of producing 9.5 GPM (gallons per minute) of hot water. This is an important factor when considering a purchase. If your household consists of a large family, you will require the simultaneous use of hot water for several purposes. In that case, this model proves to be a great investment. With it, you will be able to run a couple of showers at the same time, along with a washing machine. This would be impossible with a lesser model.  

What About Higher Demand Application?

In case your needs go even beyond, you will benefit from the expansion possibilities. Namely, the EZ-Link cable. This is Rheem's technology which enables two such tankless units to be interconnected and perform with double the power, as one single unit. Bear in mind, however, that the EZ-Link will enable you to connect only two identical Rheem models. Still, it could very well be worth your effort and investment. Using two units could satisfy all hot water needs, even for a very large family. And when we say large, we mean one that has up to 6 bathrooms!

Additional Features

In addition, the Rheem RTGH-95DVLN gas tankless water heater comes with a digital remote control unit. This is another handy feature that helps combine its powerful performance features with an ease of use normally associated with "lighter" models.

Finally, with its built-in freeze protection, this model was designed to allow unobstructed use at temperatures as low as -30C. Wherever you may plan on installing it, this should be enough in terms of winter protection.

Warranty

This unit comes with a 5-year limited warranty on its parts, as well as a 12-year limited warranty on the heat exchanger.

Installation of Rheem RTGH-95DVLN

As for the installation process, it should not provide a major headache even if you opt for a DIY approach. The Rheem RTGH-95DVLN package will arrive with a manual which also covers the installation process in detail. It also contains a 10 ft. thermostat wire and a 120 V power cord.  

However, each home (or commercial venue of use) is individual. Thus, the pertaining venting systems can prove to be a high task during initial installation. Therefore, we recommend that you hire a licensed professional for this job. This will increase your overall cost, but it will be worth it.

Safety First

As for safety measures, the unit comes equipped with the OFW (overheat film wrap). It is a feature patented by Rheem so as to provide protection in case of an exchanger breach. The OFW is placed around the heat exchanger and provides an unparalleled degree of protection.

Last but not least, it features its own Self-Diagnostic System. It is best described it as a constant monitoring function applied from the inside. By means of a digital display, this system will warn you about any malfunction that may occur (gas supply, venting system, etc.). Also, it will make any maintenance work and check-ups performed by authorized professionals much easier and quicker. And, of course, its primary purpose is to show you the temperature settings.

Environmental Footprint

As for its emissions footprint, this Rheem model is environmentally-friendly. Due to its overall efficiency, it produces a low level of NOx emissions. In addition, the low-NOx system means that you will not be restricted in terms of the location where the unit will be placed.

Also, this model is ENERGY STAR-certified. What does that mean? Well, it is a labeling system that marks energy efficiency. As such, its purpose is to help consumers save money, as well as to protect the environment.

PROS

  • With its 9.5 gallons per minute supply of hot water, this model provides an ideal solution for homes that require a constant and large supply of hot water.
  • The majority of water heaters provide 0.4 GPM as the minimum flow rate. In case of this model, Rheem has introduced 0.26 GPM as the new minimum.
  • With such efficient performance stats, this unit can save up to 1100 gallons of water on an annual basis.
  • The freeze protection technology makes it ideal for use in the coldest of climates; also, it can be used at an elevation of up to 9,840 ft above sea level.
  • Its compact size makes sure that it will leave sufficient extra space in your home, and then some.

CONS

  • As described, this unit is not meant for smaller households. This is not a Con per se, but we do believe it should be stated that this powerhouse of a water heater is aimed at large consumers.
  • For many people, the price tag on this unit can prove to be a major Con. Indeed, it is on the expensive side. Along with the cost of the heater, be prepared to pay additional installation and setup costs.
