Stiebel Eltron CF Plus 144 kW (480V Delta) 3-Phase Commercial Tankless Water Heater
The Stiebel Eltron CF Plus 144 kW (480V Delta) represents the absolute masterclass in high-capacity electric water heating. Engineered for the most demanding 480V 3-phase Delta industrial grids, this unit is designed to provide a massive, uninterrupted supply of hot water for large-scale commercial and industrial applications. As the flagship powerhouse of the elite "Hot Start" series, the CF-Plus-144-480D utilizes a specialized internal heat maintenance system that ensures instantaneous delivery. By eliminating startup lag and the "cold water sandwich" effect, this unit is the definitive solution for high-flow circulation loops, massive multi-fixture handwashing stations, and mission-critical industrial processes where thermal precision is mandatory.
