Eternal Hybrid™ and Eternal Condensing Hybrid™ work on the Counter Flow Principle. This is an opposite approach to the way the industry has traditionally built water heating appliances. Unlike any other water heater appliance, Eternal has achieved the highest efficiency in the industry without sacrificing your comfort.
In Eternal’s Counter Flow design, cold water enters from the bottom up as a way of self cleaning the sedimentation, while heat is pushed through 44 radiating transfer pipes.
The Eternal Condensing Hybrid’s innovative 3 cycle process pushes heat in 3 directions through the water and maximizes energy transfer. In simplest terms, our patent slows the exhaust of heat by reusing the energy multiple times, rather than reducing water pressure.
The end result is a small heat exchanger that is capable of replacing multiple tanks, while supplying endless hot water with consistent water pressure and doing it efficiently time after time.
