Richmond Tankless Water Heater Reviews: Types Of Richmond Water Heaters

richmond tankless water heater reviews

Richmond tankless water heater reviews has a variety of tankless water heaters, ranging from compact electric models to powerful gas units that deliver up to 9.5 GPM. Specific electric models are suitable as whole-house systems, while the smaller ones are ideal for use with a single appliance.

Richmond Essential Series

The Essential line only includes tankless electric water heaters. This series offers a selection of whole-house heaters and point-of-use heaters. It all comes down to the incoming water temperature when deciding if a model is suitable for either multiple devices or just one.

The RMTEX-04, the smallest model in the range with a power rating of 3.5 kW, supplies just 0.9 GPM. This RMTEX-36 (36 kW-unit), the biggest of its kind, is suitable for average to large homes and provides just the right amount of hot water for one sink in a warm climate.


The RMTEX-18, marketed by Richmond as a whole-house unit, can only provide 4.4 GPM and is more suited as a point-of-use water heater in cold climates rather than supplying an entire condo or small home with hot water in warm temperatures.

The RMTEX-18, part of the Essential series, is equipped with copper immersion heating elements that feature brass tops like the other water heaters in the same series. The RMTEX-18 comes with two elements screwed together to facilitate replacement, although they are built to last and may not need to be replaced that often.

This model has come with an extra level of self-regulation and the capability to be managed by an external digital thermostat.

The system regulates the power output to meet the desired hot water level while preventing unnecessary energy usage. The thermostat is precise up to a single degree, providing you with complete authority over the warmth of the water.


If you are searching for an electric power source to accommodate a medium or large-sized property, the RMTEX-36 from the Essential series is the biggest model and would be a great option. This system can offer 8.8 gallons per minute, enough to supply most of your home’s appliances with hot water simultaneously, even if you live in an icy climate.

The RMTEX-36, similar to the RMTEX-18, has a top-notch thermostat responsible for operating the dial on the front part of the machine. The temperature is displayed on an LED display. This unit is much more potent than the RMTEX-18 and contains four copper immersion heating elements that can be serviced in the field.


The RMTEX-11 from the Essential series is a sizable point-of-use model, offering 2.68 gallons per minute flow rate. This water heater is incredibly energy efficient, so it is a practical alternative to a tank water heater. With this option, you can get hot water whenever you need it, for however long you need it.

You can alter the thermostat in single-degree increments between the range of 80°F and 140°F, allowing you to adjust the temperature to your preferred setting. The temperature is on the electronic screen on the outside appliance.

The RMTEX-08 and RMTEX-13 are comparable to the RMTEX-11 but with higher flow rates – 1.95 GPM for the former and 3.17 GPM for the latter. Besides the power, the models in the Essential range have very few distinctions.

Encore RMTG Series

Gas water heaters are not as efficient as electric heaters, but they are more economical as gas is cheaper than electricity. The Encore RMTG series of heaters are not highly efficient but are more efficient than the products from several other companies. The primary factor is the low-input pilot that lessens the quantity of gas consumed by the heaters when not in use.

Furthermore, these models are fitted with burners that produce little emissions, thus reducing their fuel requirement and making them more eco-friendly and economical. Every water heater is non-condensing in nature. Some are built for indoor applications, while others are for outdoor applications.

7.0 Outdoor


Even though it is the smallest member of the Encore RMTG family, the 7.0 outdoor model is perfect for any instance when you require hot water as it reaches a maximum of 7.0 GPM.

This system has a minimum flow rate of 0.40 gallons per minute when it is activated, and the rate can go as low as 0.26, meaning that you will still have hot water even when the flow reduces.

The 7.0 model has been designed to avoid any wastage of hot water and is pre-equipped with a recirculation kit. While this additional feature increases the cost, it can significantly save thousands of gallons of water in a year, making it an economically viable option.

The unit comes with hot-start programming to enhance convenience. This feature maintains the readiness of the unit to fire up at all times. Therefore, you will get immediate access to hot water, eliminating the need to endure a chilly stream from the tap.

The 7.0 outdoor version of the product has a digital remote control, the widest gap between the walls permitted by the industry (½ inch), and the package includes 10 feet of thermostat wire.

This model also has an indoor version with a slightly increased energy efficiency of 0.82 UEF compared to 0.81 UEF. The right system is essential if you plan to put a gas heater inside the house (which should include 120v of electricity).

If not, you would need to pay more for the set-up. The external model comes with frost protection that can handle temperatures as low as -30°F, making it ideal for nearly any environment.

8.4 Indoor

The Encore RMTG series has the 8.4 indoor model available for more extensive hot water usage. This model has a capacity of 8.4 GPM, which is enough to meet most households’ needs, even in the chilliest climates. Furthermore, it is capable of operating up to 8,400 feet of altitude.

This model is a great, eco-friendly option given its 0.82 UEF energy efficiency rating and its ultra-low NOx burner. Additionally, it is also secure, featuring Guardian OFW overheat film wrap. This capability enables you to program the thermostat to a higher setting, thus avoiding the risk of the heater becoming too hot.

You can set the thermostat to a maximum of 140 degrees Fahrenheit, the same as electrical models. You can buy an upgrade kit if a higher temperature is required, like in a commercial setting.

This product is accessible in a form for both indoor and outdoor uses. If you go for the alternative for outdoor use, you should be aware that it has a low energy efficiency rating of 0.81 UEF, which is only a slight difference. Nonetheless, it is still much higher than the energy efficiency rating of any tank model.
