Reviews  | Submit a Review

Richmond tankless water heaters are designed as gas-powered, condensing and non-condensing models that are used in residential and light commercial applications, for on-demand and continuous supply of hot water, offering great innovative features. Richmond tankless article reviews all the important features and models.

Features and benefits

All Richmond tankless water heaters are built to provide an endless and on-demand hot water with the reduced temperature fluctuations, utilizing the high-end technology and several advanced features, which are shown below.

Small and compact

Richmond tankless models are small and compact in size, and since they are wall mounted, they are great for installations where the space is an issue - small apartments and houses, cottages, offices and garages. They can also be used in whole-house applications where there is a high hot water demand such as the luxury bathrooms with multiple fixtures, hot tubs and jetted tubs.

Energy efficient

Richmond tanklessModels with the energy factor of 0.87 or higher, are Energy Star qualified, and therefore, eligible for government grants and utility rebates, providing even more savings to the homeowners. Condensing types are more efficient than non-condensing models.

Condensing water heater utilize two heat exchangers where one is used to preheat the incoming cold water by utilizing the exhaust gases while the other one - primary is where the water is heated from the gas burner (non-condensing have only one heat exchanger). This action results in an increased efficiency and great savings - condensing models have the energy factor up to 0.94, while the non-condensing lower - 0.82.

Safe operation

Exclusively made by Rheem and applied for Richmond tankless water heaters are Guardian SBT sensing burner technology, Guardian OFW overheat film wrap, oxygen depletion sensor and the feature that allows high-altitude installations (up to 9840 ft).

Environment friendly

Richmond on demand water heaters are equipped with the Low NOx burners which allow them to emit less pollution during the gas combustion; which is making them eco-friendly and "green." The mid-efficient, non-condensing models heat water resulting in an ultra-low NOx gas emission.

Advanced electronics

Every Richmond model is electronically controlled for precise temperature control and self-diagnostic, great for maintenance and troubleshooting. The temperature of the outgoing hot water is factory set on 120 F, but using the remote control you can easily set it in the range from 100 F to 140 F. The temperature and error codes are shown on the digital display of the remote controller.

High water flow rate

While the largest of Richmond tankless water heaters comes with the 9.5 GPH water flow rate, which makes it ideal for larger homes with up to 3 bathrooms, multi-unit capability allows them the usage in high demanding applications.

EZ-Link cable allows more hot water production, by linking two Richmond tankless models into one system. For high demanding applications there is also an option to link up to 20 units by using the manifold control assembly.

Flexible venting

Condensing indoor models use the 2" or 3" PVC direct venting system for removing the products of combustion from the gas combustion chamber, out, while the outdoor units are ventless. Non-condensing models utilize more expensive 3"/5" stainless steel concentric type vents.

Easy gas conversion

All the models are factory built to use natural gas, but have an option for conversion to propane gas.

Modulating gas burner

As it can be seen from the comparison table below, Richmond tankless water heaters come with the gas input between its minimum and maximum value which means that they adjust its power based on the required temperature and water flow - the water heater uses the modulating gas burner and gas valve for this operation.
