Are you living in a region known for its long and cold winters? In such conditions, a natural gas tankless water heater does not get any better than Rheem RTGH-95DVLN. This water heater is a beast in extremely cold weather. Let’s have a look at how it manages to tackle the cold and many more of its unique features.
Energy Savings & Performance
Rheem RTGH-95DVLN is an energy star approved tankless water heater with an energy efficiency rate of 94%. This third party approved rate will give you an idea about the fair amount of energy you will be saving through using this product.
The flow control feature of the unit promises to save you up to around 1000 gallons of water per year. This control system works by adjusting the flow rate of the water, such as decreasing the rate until the water temperature reaches the set temperature level and only increasing it while supplying you with sufficiently hot water.
Moreover, with Rheem RTGH-95DVLN, you do not need to worry about lower flow rates since the activation flow rate required by the unit is as low as 0.4 GPM. It means that you will have your hot water even in low demand situations.
Another outstanding feature of Rheem RTGH-95DVLN is that it works perfectly in higher altitudes and colder weather, even in storm-prone areas. It is said to work efficiently up to 8.400 feet up from sea level. If you are living in a mild climate, this beast of a water heater will supply you with 9.5 gallons of hot water per minute, which is enough to run four fixtures at a time. However, it is still great for colder climates even though the capacity will drop slightly, depending on the inlet water temperature. This means that it will let you run say two fixtures at a time instead of four in colder climates, which can still be considered as a good performance.
Furthermore, there is a 10ft thermostat cord included with the unit, to be used in temperature sensitive regions to increase efficiency and a remote control for the digital control of the unit. The remote control and the digital display are crucial for the easy use of the unit. Plus, they contribute to the energy efficiency of the unit by letting you set the exact temperature in increments of 1oF. Also, you do not need to worry about freezing possibility in colder regions thanks to its freeze protection, which is applicable down to -30oF.
The safety features of Rheem RTGH-95DVLN do not end with freeze protection. Its self-diagnostic system constantly ensures that the unit is functioning properly at all times. In case there is something wrong, it warns you. This way, you will be avoiding any fatal accidents if there is any fault with the connection, venting or the supply line if the unit.
Rheem RTGH-95DVLN also features hot start programming which minimizes water fluctuations when the tap is turned on and off frequently. In other words, this unit saves you from cold water surprises during your relaxing bath. Last but not the least, Rheem RTGH-95DVLN is a very environment-friendly unit with its ultra-low NOx emission levels, which we believe is a very important aspect considering the global warming that the world is fighting against.
Design & Installation
79 pounds and 18.5 x 9.8 x 27.5 inches, Rheem RTGH-95DVLN can be considered as a compact unit. However, other than its compactness, the real reason that brings it one step ahead of the other gas tankless water heaters is the fact that it can be installed both inside and outside. It has a two-pipe direct vent system fit for PVC pipes and a built-in electric blower. Also, it comes with a ½” gas line compatibility mode.
Another important extra of the unit is that it contains an E-Z link wire which can be used to connect two tankless water heaters so that they can work together as one. This might come very handy in situations with increased water demand.
We do not suggest that you install this unit by yourself unless you are very good and experienced in this kind of handiwork. Because if you are not, the installation process might go on forever. We advise that you leave the installation to a professional. You will have to save some extra money for that but you probably will save a lot of time as well.
Rheem RTGH-95DVLN has a pretty impressive warranty period: 12 years for the heat exchanger, 5 years for the parts and 1 year for the labor. Apart from the warranty, the manufacturer has taken some measures to increase the durability of the unit. For instance, the heat condensing body is made of stainless steel so that you will not have to worry about corrosion or rusting. Also, the overheat film wrapping of the unit will ensure that dangerous temperatures will be avoided. We believe that with Rheem RTGH-95DVLN, you will be on the safe side in terms of durability.
