How to choose a heater for an engine?

The Hotstart heating system has multiple models and thermal power options, making it difficult to choose the appropriate system for the engine.

Thermal power is almost always an important consideration factor. The thermal power is too low, making it difficult for the engine heater to maintain the engine cylinder at the optimal temperature, resulting in excessive power consumption. If the thermal power is too high, it may pay for unnecessary thermal power and shorten the hose

And the service life of the seals.

When choosing a heating system, it is best to have a thorough understanding of the engine size and the total amount of coolant in the engine water jacket. The following factors also need to be considered:

Expected minimum temperature that the engine may be at

When the engine may be affected by wind or other factors that may reduce heating efficiency, if multiple systems (coolant and oil or dual fluid system) are intended to be used to heat the engine, if temperature difference circulation (based on convection) or forced circulation is intended to be installed

(Pump driven) Heating system

For temperature difference circulation heaters and HOTfloW heating systems, these factors can be simplified into a basic rule, which is to use engine displacement size and minimum expected temperature as starting points. For most small or medium-sized engine applications (5 to

50 liters), this rule can estimate the heating power very well.

If the temperature at the location of the engine will remain above 0 ° F (18 ℃):

03 × [cubic inch displacement of engine]=wattage required for heater, or

0183 × [engine displacement]=required wattage of the heater.

If the temperature at the location of your engine will be below 0 ° F (-18 ℃):

05 × [cubic inch displacement of engine]=required wattage of heater, or

0305 × [engine displacement]=wattage required by the heater.

For larger or more complex applications, especially those that require multiple heating systems, large amounts of liquid, or other factors, it is best to consult us directly to find a heating system that can provide the required thermal power.
