Eternal GU120 is the affordable and flexible alternative to traditional tank water heaters in retrofit applications. The efficient unit provides endless hot water, runs on a 1/2" gas line for easy installation and supports up to two simultaneously applications.
This workhorse provides continuous hot water for residential and commercial applications. The stainless steel internal components and larger heat exchanger make the GU145 a powerful upgrade. The GU145S supports up to three simultaneous applications.
When only the best will do, you need the GU195S. Our most powerful unit is designed for more demanding residential and commercial installations. In commercial applications, the GU195S can be combined with additional storage to support unpredictable surges in the demand for hot water. It also works with a recirculation line.
For large residential applications, the GU195M units can be electronically linked together and common vented. Multiple units creates redundancy and increases the system’s ability to adjust to demand. The primary unit will alternate with the other units in the system to distribute the workload. When needed, all units will produce hot water simultaneously.
