Aquastar 125HX

Controlled Energy Corporation has introduced the Aquastar 125HX model tankless water heater. It uses a hydro-generated ignition system that requires no standing pilot, electricity or batteries. Hydro-generated ignition uses the flow of water to generate electricity. When a hot water tap is opened, cold water flows through the 125HX's hydro generator. The flowing water spins a tiny turbine, which in turn instantly produces electricity. This electricity creates the spark required to light the burner, and the water is then heated as it passes through a copper heat exchanger.
