Built with durability and longevity in mind, this product is available in four sizes — 30, 55, 80, or 119 gallons — making it flexible for a broad range of applications.

The versatility of this unit allows it to be used for a small amount of water or connected in line with a main water heater for instantaneous hot water.

The system features a 119-gallon storage tank along with two CU199 Rinnai Tankless Water Heaters that work together to offer the benefits of both tank and tankless technology.

This resettable, testable protection device can be installed on any style water heater to shut off incoming water supply, preventing additional water flow to a damaged water heater.

The Everlast Light Duty Commercial Water Heater features durable and light-weight 316L Stainless Steel for the inner tank design and provides increased recovery for maximum output and first-hour delivery with its unique three-element energy booster design.

The Polaris, which operates at a cost-saving thermal efficiency of up to 96 percent, easily installs and pairs with recirculating systems or domestic space heating systems.
