Micro-processor Controller Electronics

The Malaga 4 water heater is equipped with the latest Propex electronics for accurate digital control of the heaters operation and safety functions. The switch panel features a 3 position switch for selecting either “gas only” or “gas and 230v”. If you want to use the heater on 230v only, you simply switch off the gas tap that supplies the heater whilst leaving the switch in the “gas and 230v” position. The yellow L.E.D. on the switch panel lets you know when the gas burner is operating and also, by flashing a certain amount of times, indicates various fault conditions.

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.
