See all the benefits from installing a Rinnai RL94. Find out how Rinnai tankless water heater heats water fast, continuously and delivers hot water on demand and in endless supply. Discover the most advanced features and specs, such as the Circ-Logic and high water flow rate.
Rinnai RL94 water heaters are direct vent models that utilize forced combustion of the natural and propane gas, and are designed for an indoor and outdoor installation. Which one you will buy depends on your preference and installation viability.
Rinnai RL94i is an indoor unit that uses the concentric venting system for venting gases out and taking the fresh air in for gas combustion.
Indoor models are designed with the sealed combustion, and with the modern, sleek design are perfect for installation in the bathroom or kitchen.
No need for the special technical room as with the storage tank-type heaters.
On the other side, Rinnai RL94e is for the outdoor installation only, usually in the recessed enclosure with no venting required - vent slot is provided.
Both models are compact and wall mounted, which means less space is occupied.
These models provide a continuous supply of hot water, any time at the preset temperature and when the hot water tap is open.
The temperature of the outgoing hot water is constantly monitored by the advanced electronic board, which adjusts the water flow to maintain the set temperature.
Both models belong to the Rinnai "Luxury" series and is recommended for high hot water demanding homes. Maximum water flow is approximately 9.8 gallons per minute and are supplying up to five applications simultaneously, while the minimum activation flow rate is 0.4, which allows small jobs such as hand washing, shaving... For higher demanding homes, model RL94 can use the EZConnect cable to connect two units.
Models RL94i and RL94e are high efficient tankless water heaters that come with the energy factor of 0.82, making both types Energy Star compliant and eligible for rebates and government grants.
Within the Luxury group, there are also Rinnai RLX models that are the same as RL models, but are built for indoor use and are utilizing natural gas only, while complying with the strict NOx emission standards - known as ultra Low NOX. The maximum power it can achieve is slightly lower than power of RL94i, 192,000 Btu, while the minimum is the same.
Rinnai RL94 tankless water heaters are equipped with the 24-hr programmable digital controller for an extra convenience and uses the error code system for easy troubleshooting. The controller is actually built into the front panel, and it provides easy monitoring, temperature control and troubleshooting. The error code, such as 02, 03, 11, 12, 31... shows what is wrong with the water heater and possible solution for the problem.
All the components are made of the quality materials, including the heat exchanger which is made of the commercial grade copper. Due to the high quality of heat exchangers, Rinnai provides 12-year warranty ensuring its resistance to the high mechanical and thermal stress. This is why Rinnai water heaters from "Luxury" series can be used not only in residential water heating, but manufactured homes and commercial applications.
The gas modulating burner allows water heater to work in the range from 10,300 to 199,000 Btu/hr using both natural and propane gas, and provide hot water with the temperature between 98 F and 140 F. This is what makes the shower much more pleasant with less temperature fluctuation and savings up to 40% in the energy.
With the built-in Rinnai Circ-Logic feature, RL94 models can use the external pump and dedicated recirculation line for faster hot water delivery to the faucets, resulting in better efficiency and comfort, and off course happy customers.
