Ensure Reliable Generator Performance in Cold Climates

Preheating Solutions for Standby Generators

Control Temperature. Improve Performance.

Maintaining the right engine temperature is essential for reliable generator performance. Hotstart preheating systems keep standby generators warm and ready, reducing cold-start risk and ensuring predictable operation when power is needed.

Most standby generators rely on block heaters that run continuously, consuming significant amounts of electricity to maintain temperature – often without operators being aware of the total energy use. This leads to unnecessary energy costs and inefficient operation. Hotstart uses high-efficiency heating to maintain precise temperature, reducing energy use and operational costs – with up to 60% savings, especially for sites with multiple generators.

The solution is designed for both new installations and retrofit, allowing seamless integration into existing generator systems. For facilities with multiple standby generators, the combined energy savings can result in substantial cost reductions over time. As an approved Hotstart partner in the Nordics, BOS Power provides local expertise for implementation, upgrades, and ongoing support.

Benefits with Hotstart:

Reliable startup in low temperatures
Reduced engine wear and thermal stress
Stable and predictable generator performance
Reduced energy consumption compared continuously running block heaters
Easy integration in new and existing systems

A Smarter Approach to Generator Heating

Most standby generators use continuously running block heaters, consuming electricity 24/7 – often without delivering efficient temperature control. This results in unnecessary energy use and higher operating costs over time.

Without Hotstart:

Continuous heating regardless of actual need
Unnecessary energy consumption
Uneven temperature control
Increased risk of delayed or failed starts in cold conditions

With Hotstart:

Temperature maintained based on actual conditions
Immediate and reliable start capability
Stable and predictable performance
Reduced energy consumption during standby

Technology Insight

How Hotstart Supports Reliable Generator Performance

Unlike traditional electric resistance heaters, Hotstart’s high-efficiency systems use controlled heat transfer to maintain optimal engine temperature. This reduces energy consumption while avoiding overheating and ensuring consistent readiness.

Advanced systems capture and reuse heat from the surrounding environment, improving efficiency without compromising start performance.
