Description12v Propex Heatsource HS2000 Blown Air HeaterEfficiencyThe HS2000 delivers clean, high-efficiency heating for vehicles and boats.Forced air combustion and a Propex two-stage stainless steel heat exchanger maximise heat output while minimising waste. Outside combustion air mixes with gas through three aeration stages and ignites automatically to heat the exchanger’s large surface area.A fully room sealed design vents all combustion gases through a 22 mm stainless steel flue, while recirculated cabin air avoids cold outside air for greater efficiency.Advanced current reducing electronics and a high quality motor and fan keep power consumption low even the HS2800 draws under 2 amps in normal use.Quiet OperationPropex heaters deliver strong airflow with minimal noise. Balanced fans, smooth enclosed motors, and ball race bearings reduce vibration without sacrificing heat output.Microprocessor controlled electronics regulate motor voltage to maintain consistent fan speed from 10–15 volts, even with chargers or solar systems connected.SafetyHS series heaters meet the latest European appliance and electronics standards and exceed Electromagnetic Compatibility requirements. Intelligent electronics continuously monitor flame status, temperature, airflow, gas valve operation, and voltage. If any value moves outside safe limits, the heater shuts down immediately and displays a fault code via the thermostat’s flashing red light.InstallationThe HS2000 includes a complete fitting kit for vehicle and marine installations. Installers typically mount the unit in a cupboard or bed box and route the flue through the floor and out the vehicle side using flexible stainless steel ducting.The kit includes 22 mm stainless ducts (750 mm for vehicles, 1 m for boats) with EN624-compliant end caps. Warm air distributes through durable 60 mm or 76 mm flexible ducting, with multi-outlet systems using directional and closable vents connected via correctly sized Y-branches.
