The Ventech LHG (Liquid Heat Generator) is a High Performance, Rapid Supplemental Heater that requires NO FLAME, No Fuel lines, and produces No Exhaust.

This LHG kit is designed for model year 2020-2024 Chevy/GM/GMC Duramax Diesel Trucks equipped with the 6.7L Cummins diesel engine and a single alternator.

The LHG provides fast engine and cabin warmup and window defrost while reducing excessive warmup idling and cold running – resulting in fuel savings, reduced tailpipe emissions, and reduced engine wear and tear.

The LHG adds 8kW - 16kW (27,000 - 55,000 Btu) of additional heat to your engine coolant circuit and heater core instantaneously based on engine RPM.

Fully automatic and managed by an Electronic Control Unit (ECU), the LHG engages and disengages based on coolant temperature, load, and other engine and environmental conditions.

The LHG is provided as part of an installation kit tailored specifically for each vehicle application. The HeatStroke LHG is much easier to install than burner-based heaters, with no connection to the vehicle fuel system and no added exhaust pipe necessary.

Installation requires only basic workshop tools.
