Hotstart Heating Systems

Since 1942, HOTSTART has been a world leader in the design and manufacture of heating systems that improve engine and equipment reliability. With over 75 years of experience, the company continues to provide high quality, reliable preheating systems to customers needing easy engine starts, immediate full power and reductions in maintenance, fuel consumption and harmful emissions.

Heating coolant and keeping it circulating in an engine block when it is in standby mode keeps the generator ready to start at a moment’s notice. HOTSTART’s wide range of heating solutions for generators includes traditional convection-based heating systems as well as efficient pump-driven models. Ensure your facility is ready to stay powered when it matters most with HOTSTART heaters.

Engine Supplies & Services supply & support the full range of HOTSTART heating systems. With competitive pricing and a large range of units in stock the ESS sales team is standing by to support all your HOTSTART requirements.

Thermosiphon Heaters

HOTSTART’s externally mounted engine heaters circulate heated coolant throughout the engine block. Convection heating allows coolant to naturally rise from the heater and circulate through the engine’s water jacket without the use of a pump. HOTSTART thermosiphon engine heaters maintain an engine’s operating temperature during downtime and serve as an excellent cold weather or emergency starting aid while eliminating needless idling.

HOTflow Forced Circulation Heater

HOTflow forced circulation 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 35% in energy consumption while extending heater element life and reducing maintenance work.

Industrial Immersion Heaters

For many applications, industrial immersion heaters are the solution of choice to resist the effects of cold temperatures. Immersion elements are designed to transfer all energy directly into the medium which is being heated — making them both highly efficient and effective for preventing gelling and condensation. HOTSTART immersion heaters are manufactured with a fixed-setting thermostat. Some models may be available with an adjustable thermostat. All industrial immersion heaters are CSA approved.

In-Block Heaters

HOTSTART’s line of In-Block heaters mount directly into the water jacket of the engine, reducing engine wear due to cold starts by up to 50%. Warming the engine to the proper temperature also reduces idling and cranking time, saving fuel and increasing battery life.

HOTSTART in-block heaters are available for most leading makes and models of heavy-duty truck engines and are CSA approved. To specify an in-block heater for your heavy-duty engine, please select your engine manufacturer and model in and Engine Supplies & services can identify the correct spec and model for your application.
