The Propex HS2000 heater is an automatic thermostatically controlled blown air heating systems fuelled by propane or butane gas. Heatsource is designed for a variety of automotive and marine applications as a source of heat totally independent of the engine.

Propex Heatsource with single outlet 2.0kw Heatsource with single outlet vehicle fitting kit including thermostat, 1m ducting, 0.75m flexible stainless steel exhaust & comb air inlet pipe, outlet & inlet grills, brackets, cables and comes with an Analogue or Digital controller.

The HS2000 like the larger HS2800 heaters are automatic thermostatically controlled blown air heating systems fuelled by propane or butane gas. Heatsource is designed for a variety of automotive and marine applications as a source of heat totally independent of the engine.

Propex HS2000 Applications

Propex Heatsource blown air systems are used in many applications throughout the world, these include Motorhomes, Caravans, Boats, Cranes, Horseboxes, Mobile Workshops etc. Both 12 and 24 volt versions are available with either an Analogue or Digital controller.


The Propex HS2000 is supplied as standard with a solid state electronic thermostat which automatically switches the unit on and off to maintain the desired temperature. When the room temperature drops below the selected level, the Heatsource will automatically ignite and run until the cabin reaches the selected temperature. The thermostat is an easy to fit surface mount design and integrates with the new electronics fitted to the HS2000 and HS2800 heaters. An easy to operate panel mounted digital timer/thermostat specifically designed for Heatsource, is also available. Unlike some heaters, there is minimal electric current consumption during ignition so cycling the Heatsource on and off does not have the effect of additional battery drain.


With forced air combustion and the Propex two stage stainless steel heat-exchanger, the HS2000 is a clean and highly efficient way to heat your vehicle or boat. Air for combustion is taken from outside and passed into the combustion chamber having been mixed with gas during three aeration stages, it is ignited automatically and heats up the large surface area of the heat-exchanger. The Heatsource units are totally room sealed and exhaust all products of combustion externally through the neat 22mm i.d. stainless steels flue pipe. To add to the efficiency, cabin air is normally re-circulated in preference to using cold air from outside. The HS series heaters are also very efficient on electrical current consumption, the high quality motor/fan combination and innovative current reducing electronics, both of which have been improved in the latest versions, means that even the larger HS2800 draws less than 2 amps during normal operation.

Quiet Operation

Propex heaters are designed to be quiet in operation without compromising air throughput and heat output. There will always be some air noise from a system that produces a healthy throughput of air, however, by using high quality balanced fans and smooth enclosed motors with ball race bearings, noise is kept to a minimum. Noise is also unaffected by high voltage, a common occurrence with battery charges, solar panels etc permanently wired. The micro-processor electronics regulates the motor voltage so that the fan speed does not alter from 10 to 15 volts.


Heatsource blown air heaters conform to the latest European standards for both the appliance and the electronics and during the rigorous testing the focus is very much on safety. The heaters also have to comply with an enhanced version of the Electro Mechanical Compatibility Directive to ensure they do not interfere with other electronics and that they are immune from interference by other electronics.

The intelligent electronics are continuously monitoring the operation of the heater to make sure everything is operating correctly and safely. This includes monitoring of the flame, case temperature, combustion airflow, gas solenoid valve and voltage. Should any of these stray outside of the predetermined levels, the heater will be switched off and the red light on the thermostat will indicate a fault by flashing a certain number of times.


The HS2000 is are supplied with a fitting kit to suit either a vehicle or a marine application. In vehicles and caravans the unit is usually mounted in a bed-box or cupboard, flued downwards through the floor and out to the side of the vehicle using flexible stainless ducting. The 22mm i.d. ducts are supplied as standard in lengths of 750mm for vehicles and 1 metre for boats. The ends are finished with neat stainless steel end-caps which comply with EN624. The heat is ducted to one or more outlets through tough highly flexible 60mm or 76mm ducting. In the case of multi-outlet installations, the first outlet is an open outlet with directional control and the rest are closable and are used in conjunction with the appropriate sized plastic Y-branches. Marine applications feature an attractive polished stainless steel through hull fitting which accepts the stainless steel pipes for the flue outlet and the combustion air inlet. Extra ducting and stainless steel bulkhead mounting brackets are also part of the marine fitting kits. There is a choice of Analogue or Digital controllers.


The chart below reflects the consumption of gas if the heater was running continuously. In reality, both heaters have similar very high efficiency ratings, so the overall gas consumption will be about the same because the HS2800 will be running for a shorter period of time before the thermostat switches it off.

1 FAQ on the Propex Heatsource HS2000 V1 with single outlet 2.0kw (12V)


I am looking for a reasonable priced heater to install in my horse lorry living area and wonder if you could assist? Thanks Jenny


Any heater fitted in a horsebox must be room sealed. That is the heater must draw air from outside and all flue gases must also go to the outside.
We can only recommend that you fit a Truma S3002 heater or a Propex Heatsource 2000.
