Each of the several types of tankless water heaters that Richmond produces, whether gas-powered, condensing, or non-condensing, is outfitted with a variety of innovative, energy-saving technology. 

Tankless units are used in residential and light commercial applications to offer an on-demand and continuous supply of hot water.

These applications make use of the units to save space. Tankless systems save space in additional ways.

If you are looking for a new tankless water heater then the pens made by Richmond may be the best option for you.

In this article, we will cover all of the most important features of these water heaters, as well as the various models that you can buy. 

Read on to see if the Richmond water heaters are the right units for you!

Key Features

All of the tankless water heaters that are produced by Richmond are designed to supply an infinite supply of hot water on demand while simultaneously reducing the amount of temperature variation that takes place.

This is accomplished by utilizing cutting-edge technology and a number of other advanced features.

Here are some of the most important features of these water heaters. 


These tanks are ideal for installations in locations where space is at a premium, such as in garages, workplaces, cottages, and small apartments and homes.

This is because the water heaters are very small and compact and because they are placed on the wall. 

They are especially helpful in applications that run the entire home and have a high demand for hot water, such as in bathrooms that have a lot of different fixtures, hot tubs, and jetted bathtubs.

These kinds of applications require a significant amount of hot water that this tank cannot provide. 

Energy Efficient 

The Energy Star program only grants certification to products if they have an energy factor of 0.87 or above.

As a consequence of this, many models qualify for government subsidies and utility rebates, which result in even larger cost savings for homeowners.

In terms of their ability to conserve energy, condensing models are miles above their non-condensing counterparts.

In condensing styled water heaters, there are two types of heat exchangers: the first heat exchanger is able to preheat any incoming cold water by making use of exhaust gases, and the second heat exchanger, also known as the primary heat exchanger, is where the water is heated by the gas burner. 

Condensing styled water heaters are also known as indirect water heaters (non-condensing has only one heat exchanger).

This results in improved efficiency, performance, and considerable cost savings; the energy factor of condensing models may reach up to 0.94, whilst the energy factor of non-condensing variants is roughly 0.82.

Very Safe

Rheem’s oxygen depletion sensor, Guardian OFW overheat film wrap, sensing burner technology and the feature that permits high-altitude installations are all components that are unique to Richmond tankless water heaters.

Additionally, the feature that permits high-altitude installations is a component that is unique to Richmond tankless water heaters.


During the process of gas combustion, on-demand heaters produced by Richmond have been equipped with Low NOx burners, which allow for significantly reduced levels of pollution to be produced by the heaters. 

Because of this, these water heaters are seen as being “green” and good for the environment.

The non-condensing models with a medium degree of efficiency heat water, which results in very few emissions of nitrogen oxides being released into the atmosphere.

Electronic Inventions 

Every model of the Richmond line comes standard with electronic control, which allows for more precise temperature management, as well as self-diagnostic capabilities, which make it much simpler to do maintenance and figure out what the issue is. 

The manufacturer has the temperature of the hot water that is discharged pre-programmed to be 120 degrees Fahrenheit; however, you can easily adjust it anywhere in the range of 100 degrees to 140 degrees by using a remote control.

The maximum temperature that can be discharged is 200 degrees Fahrenheit.

Temperature readings and error codes (see also ‘ AO Smith Tankless Error Codes: Problems And Troubleshooting ‘), if any, are displayed on the remote controller’s digital display.

This display also provides information about any problems that have occurred.

High Flow Rate

These water heaters are able to be utilized in high-demand applications due to their capacity to heat several units simultaneously.

This is despite the fact that the largest model of these water heaters has a water flow rate of just 9.5 GPH, which is why it is best suited for bigger homes that have up to three bathrooms. 

When two different tankless models of the Richmond brand are joined into a single system by means of an EZ-Link cable, the resulting system has the capacity to provide an increased amount of hot water

When using the manifold control assembly, there is also the potential of linking up to 20 separate devices for use in applications with a high level of demand. 

Flexible Venting

Condensing indoor versions utilize a 2″ or 3″ PVC direct venting system to remove the byproducts of combustion from the gas combustion chamber. In contrast, outdoor units do not have vents of any type.

Vents of the concentric variety, manufactured of stainless steel and measuring 3″ and 5″ in diameter, are more expensive and are typically found in non-condensing models.

Simple Gas Conversion

There is an option to change the models so that they may run on propane gas instead of natural gas. The models are built at the factory to operate on natural gas.

Modulating Gas Burner

The gas input that is included with these water heaters falls somewhere in the middle of their minimal value and their highest value.

The water heater does this by utilizing a modulating gas burner and a gas valve.

This enables the user to regulate the power output of the water heater following the temperature and flow of water that is necessary.

Model Overview

Tankless water heaters manufactured by Richmond are available in two distinct categories: non-condensing or mid-efficiency models (series Essential Plus), and condensing or high-efficiency models (Encore), which are larger and heavier but can be installed either indoors or outdoors. 

The following is a list of the many models that are up for grabs:

High-Efficiency Condensing Models

  • RMTGH-84DVLN -Indoor direct vent model
  • RMTGH-95DVLN – Indoor direct vent model
  • RMTGH-84XLN – Outdoor
  • RMTGH-95XLN – Outdoor

Mid-Efficiency Non-Condensing Models 

  • RMTG-95DVLN – Indoor direct vent model
  • RMTG-84DVLN – Indoor direct vent model
  • RMTG-64DVLN – Indoor direct vent model
  • RMTG-95XLN – Outdoor
  • RMTG-84XLN – Outdoor
  • RMTG-64XLN – Outdoor


Richmond, the producer of the above tankless water heaters, offers a limited guarantee on the heat exchanger that is valid for 12 years, valid for 5 years on the components, and valid for 1 year on the labor, while the product’s service life is above 20 years.

All of the tankless versions, when properly chosen for the right space, offer a continuous supply of hot water that is sufficient for as long as you require it while maintaining the same temperature as the water that is being discharged from the unit.

In addition, because the design does not have any tanks, the floor space freed up may be put to other uses.
