Using short and long burst cycles of stable-tempered water, the closed-loop heating system uses full power to bring the water up to temperature, but uses only enough power to overcome heat loss through the insulated tubes during a stabilized operation window. Water temperature remains within 1-2 degrees of the set-point, while minimizing energy consumption. Energy-saving unit runs at a maximum of 46kW. Provides portability, reduced maintenance, touch-screen operation, and sustainability and conservation.
