Applications

Propex Heatsource blown air heating systems are used in many applications throughout the world, these include caravans, motorhomes and boats. Both 12 and 24 volt versions are available.

Gas Efficiency

With forced air combustion and the Propex two stage stainless steel heat-exchanger, the HS2000E heater is a clean and highly efficient way to heat your vehicle or boat. Air for combustion is taken from outside your caravan, motorhome or boat 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 steel 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 on12 volt electrical current consumption drawing less than 1.7 amps on gas operation or 2.2 amps during mains electric operation.

Control

The Propex HS2000E 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 Propex 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 HS2000E heater. Simple intuitive controls enable easy switching between the gas and electric modes and a constant heater feedback loop enable quick and easy system diagnosis. Selectable electric hook up power levels easily ensures you do not over load your available supply.

Electric

For those using a mains hook up there is the option of using the powerful electric element with efficient heat exchanger built in. Three settings are available giving 500W, 1 KW or 2 KW of heat output and drawing a maximum current of 9 Amps. The motor speed is altered to suit each power level to ensure maximum efficiency or, when on low 500w setting keeping motor and air noise to a minimum for night time running. The heater is supplied with a mains cable and moulded 3 pin plug.

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 between 10 to 15 volts.

Safety

Propex 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.

Installation

The Propex HS2000E can be supplied with complete fitting kits to suit either vehicle or marine applications. 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. These ducts (22mm i.d. for the HS2000E) are supplied as standard in lengths of 750mm for vehicles and 1 metre for boats. The heat is ducted to one or more outlets through tough highly flexible 60mm 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.

Propex History

In the beginning came the X1 heater (circa 1985), a 1.6kw heater commissioned by the GPO and fitted into the engineers vans, these heaters were supplied with a one hour timer, once the engineer had had his hour of heat he had to get a move on or suffer the cold as the heater would not reactivate for another hour. (A directive from the GPO not ours) In total about 12000 X1 heaters were manufactured, with production being based in Lincoln.

The success of this heater led to calls from the motor-home fraternity for an efficient reliable heater gas for them and so the COMPACT 1600 was borne, this was the same as the X1 heater but being squeezed into a smaller box with the controller being mounted externally. Production of the COMPACT lasted until 1999 and moved from Lincoln to Verwood and finally to Southampton as the business grew and new manufacturing facilities were required.

The introduction of the CE requirements put an end to the Compact heater and cleared the way for the Heatsource range of heaters, the initial models were the HS1600 and the HS2800 with far greater monitoring, lower electrical current consumption and gas efficiency than had previously been seen whilstfully meeting the new European requirements of EN624.

Since then the HS1600 developed into the HS1800 and is now at the HS2000 with further advances being made in motor control and airflow sensing increasing reliability and reducing current consumption even further.

In 2002 Propex struck a deal with Belling and took over the rights to the Malaga water heater with, production moving to Southampton.

In September 2008 Propex Heating and Leisure agreed a strategic partnership with Munster Simms Engineering in Northern Ireland. Munster Simms world class LEAN manufacturing facilities based in Bangor, Northern Ireland ensures Propex is well positioned to continue its growth and benefit from the vast Research and Development facilities available there, this partnership has already seen the release into the market of the highly acclaimed combined gas and main electric heater, the HS2000E, with plenty of new ground breaking developments waiting in the pipe line.
