The 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 blown air systems are used in many applications throughout the world, this system is designed to fit under the Drivers seat (under the van) on Volkswagen Transporters T5 and T6. with the air vents coming up through the base of the driver's seat. 



The HS20000 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 campervan. 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 complete fitting kit to suit VW T5 T6. Mounted under the floor,under drivers seat flued downwards and out to the side of the vehicle using flexible stainless ducting. The 22mm i.d. ducts are supplied as standard in lengths. 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 fitted inside the drivers footwell and the rest are closable and are used in conjunction with the appropriate sized plastic Y-branches.


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.  When used with LPG tank its half cost of running a diesel heater.
