Hotstart HOTflow® CSM10308-000 Engine Heater (Style A)
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® engine heaters rely on fewer heating cycles – saving up to 55% in energy consumption while extending heater element life and reducing maintenance work.



Hotstart® engine block and coolant heaters are designed to keep diesel and gas generators ready in cold and demanding environments. Power Systems Plus supplies genuine Hotstart heaters, including pump-driven and thermosiphon models, with nationwide shipping and expert support.
