A Constant Supply of Hot Water

Save on Capex, Opex and up to 40% on energy.

Rinnai Tankless water heaters heat water directly without the use of a storage tank. When a hot water tap is turned on, cold water travels through a pipe into the unit. Either a gas burner or an electric element heats the water. As a result, tankless water heaters deliver a constant supply of hot water. You don’t need to wait for a storage tank to fill up with enough hot water.

Continuous flow water heating technology can achieve over 97% gross efficiency and boast modulation ranges from 59.5kW to 2.4kW, creating significant energy, cost and emission savings.

With the Rinnai Gas Tankless Rack System, you can harness all the benefits of tankless water heating technology, pre-assembled and ready to replace the boiler in your existing or planned boiler and storage tank water heating system.

The TRS (Tankless Rack system) - an instantaneous system - installs in place of an oldstyle boiler and provides built in redundancy by banking individual Tankless Water Heaters to ensure your hot water supply keeps flowing even if a unit is down. The TRS comes standard with Rinnai’s Heavy Duty Commercial Condensing Water Heater that boasts 95% thermal efficiency and a commercial application.

Rinnai’s Tankless Rack System™ is a true water heating solution. Fully approved for direct contact with portable water it offers complete flexibility of design for any water heating purpose without the use of additional equipment such as heat exchangers or indirect storage tanks to separate the water being heated from the water heater itself.

Rinnai’s Tankless Rack System™ is designed to supply a packaged water heating solution as a fully assembled system. The TRS includes preassembled water and gas connections and manifolds under the water heaters that are adequately sized to maintain optimum performance. Rinnai Gas Tankless technology provides an endless supply of hot water and the Tankless Rack System provides the ability to link multiple units together, giving redundancy and ensuring the business remains open 24/7/365.

All of the water heaters on the TRS can be electronically connected and use the multi systems control board. When operating, multiple tankless water heaters are linked together with the multi systems control board and are designed to supply equal amounts of hot water. They will also rotate occasionally to ensure equal usage throughout the entire system. On initial water flow, 1 to 3 units will start up based on the configuration of the multi system control board. Once the flow rate is determined, the multi system control board will initiate additional water heaters as required.

With Rinnai’s Tankless Rack System™ no backup is required as with conventional boiler systems.

Save at least half the capital cost. Built with superior quality and reliability, Rinnai’s Tankless Rack System™ offers the perfect BTU upgrade of an old-style commercial water boiler that is reheating storage tanks. On retrofit applications, often times you can keep your existing tank and pump and simply replace with the lower cost and better performing TRS.
