HOTflow™ Engine Heaters

HOTflow™ engine heaters feature an integrated pump that circulates warm coolant throughout the entire engine at uniform temperatures. Constant circulation of the coolant eliminates hotspots that can deteriorate heater hoses, harm engine seals and diminish coolant life.™ HOTflow™ heaters rely on fewer heating cycles - saving up to 2000 kilowatt-hours per year in energy consumption while extending heater element life and reducing maintenance work.
