Frequently Asked Questions About Rinnai's Tankless Rack and Common Vent

Rinnai Tankless Water Heaters are perfectly suited for virtually any commercial application. Customers of all sizes and configurations in multi-family, hospitality, healthcare, education, food service, retail and more trust Rinnai to deliver an endless, efficient supply of hot water.

The flexibility and capability of the TRS allows it to replace just about any existing water heating product, from domestic boilers to traditional tank-style water heaters, so long as the necessary gas, venting and installation requirements are present. In fact, the modular design can handle up to 4.9M BTU. And even in cases where demands are smaller, Rinnai Tankless Water Heaters can provide significantly more energy efficiency and reliability than tank-style water heaters.

Rinnai Tankless Water Heaters are designed to achieve peak efficiency and performance without the use of a storage tank. Because they only operate on-demand, they use far less energy than tank-style water heaters. However, they can be used in conjunction with a storage tank to suit the needs of a specific application. Please consult with Rinnai’s Application Engineering group to determine the best solution for your project.

When continuous, on-demand hot water is needed, our tankless units work very well with a recirculation pump. Plus, the modulating technology and minimum fire rating of the Rinnai Tankless Rack System enables it to maintain consistent temperature in a return line with limited waste, only using the energy necessary to keep the line heated when required.

Please note that all tankless water heater installations are different.
