Rheem RTGH-95DVLN & RTGH-95DVLP : Review & Comparison

The only real difference between them is that one runs on methane (natural gas) while the other runs of propane.

Do you live in a harsh winter climate where hot water is essential to your survival?

Or maybe you just can’t go to bed without a scalding shower to wash the day away.

If you’re someone who demands a lot from their water heating system, here are two units that can get the job done:

  • Rheem RTGH-95DVLN and RTGH-95DVLP

They’re functionally the same but differ in the sense that one runs on natural gas while the other runs on propane.

They offer the same high-powered performance, however, and both can be trusted to provide you with hot water no matter how cold it is outside.

These aren’t units that shy away from extreme temperatures.

If you live somewhere arctic, the RTGH-95DVLN or the RTGH-95DVLP will strike like a red-hot iron.

Let’s take a closer look at these two tankless water heaters from Rheem.

Both units have the same performance numbers, so the good news is that you don’t have to weigh their specs against one another. They both offer the following:

  • Flow rate: You’ll enjoy a staggering 9.5 gallons per minute (GPM) when you install the RTGH-95DVLN or the RTGH-95DVLP.This number far exceeds what electric tankless water heaters can do, and it’s also quite high for natural gas and propane models. It’s enough to serve anywhere between 2-4 bathrooms at once.
  • Power: Both units can require up to 199,000 BTUs, but don’t be worried about their power consumption. They’re quite energy-efficient with a 94 percent energy rating. If you’re hoping to lower your monthly bills, these can do the trick.
  • Size: Both units top off at around 80 pounds. While this isn’t the lowest weight on the market, it isn’t the highest either, and you can still install the RTGH-95DVLN or the RTGH-95DVLP anywhere you’d like. Like the name suggests, you can even install it inside your home!


One thing that natural gas and propane water heaters have in common is that they both run on live flames that warm up their internal heat exchangers.

This usually means complicated venting systems to ensure that the fumes don’t build up in the unit, but Rheem has rejected that model and come up with something better instead.

Their special low-NOx system means that you can install your tankless water heater anywhere, including indoors, and you don’t even need fancy or stainless steel vents.

PVC vents are all that’s required.

As for their power, don’t worry. The RTGH-95DVLN and the RTGH-95DVLP have you covered.

While they’re designed to function as “whole house” units that work individually, they can also be fitted together with special cables if you want to link several units at once to serve a larger home or high-demand area.

Heat Output and Flow

As previously mentioned, the flow rate of these units can be as high as 9.5 GPM. What’s even more remarkable is that this flow rate won’t dip just because it gets a little cold outside.

While you can expect minor delays in extremely cold temperatures, both the RTGH-95DVLN and the RTGH-95DVLP are equipped to handle temperatures as low as -30°F, and they’re designed to withstand high altitudes too.

They can be used at elevations exceeding 9,800 ft above sea level! Mountain residents, these are the tankless water heaters you need.

The temperature itself can be adjusted on the digital display located on the exterior of the unit.

You can also use a Rheem-provided remote control to change it from a distance.

Note that both the RTGH-95DVLN and the RTGH-95DVLP have a minimum flow rate of 0.26 GPM. This means they won’t start heating water unless it’s already flowing at 0.26 GPM.


While I always recommend letting a trained technician handle the installation of tankless water heaters, you won’t have much trouble with the RTGH-95DVLN or the RTGH-95DVLP if you decide to DIY it.

There’s a detailed instruction manual included with every purchase.

In addition, you’ll be given a number of “freebies” to help move the job along:

  • Thermostat wire
  • Digital remote control
  • Overheat film wrap (OFW)
  • 120 volt power cord

You may or may not need to order additional parts to complete your installation; it all depends on what your home looks like and how many tools you already have at hand. Call Rheem and talk to a technician to learn more.

General Use

There are both pros and cons to purchasing the RTGH-95DVLN or the RTGH-95DVLP, so let’s take a closer look at what you can expect after you swipe your credit card.


  • Powerful units available in both natural gas and propane
  • Special low-NOx system reduces fumes and emissions
  • Easy installation with self-guided instructions


  • On the higher end of most price ranges
  • Has a minimum flow rate of 0.26 GPM
  • Might need to be connected with multiple units for commercial use

What’s the bottom line?

I give both the RTGH-95DVLN and the RTGH-95DVLPfour out of five stars, so if you’re looking for a tankless water heater that can get the job done, either unit will do.

The only real difference between them is that one runs on methane (natural gas) while the other runs of propane.
