History of Propex

(circa 1985)

In the beginning, came the¬†X1¬†heater (circa 1985), a 1.6kw¬†heater¬†commissioned by the GPO and fitted into the engineer’s vans. Supplied with a one-hour timer, once the engineer had his hour of heating, they’d have to get a move on or suffer the cold. The heater would not reactivate for another hour, a directive from the GPO, not ours. In total,¬†about 12,000 X1 heaters were manufactured¬†and produced in Lincoln.

Compact 1600 Heater

The success of this heater led to calls from the motorhome fraternity for an efficient, reliable gas heater for them. Enter the COMPACT 1600. Virtually identical to the X1 heater, only squeezed into a smaller box with the controller mounted externally. Production of the COMPACT lasted until 1999. Moving from Lincoln to Verwood and finally to Southampton as the business grew. 

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, offering far greater monitoring, lower electrical current consumption and gas efficiency. These models also met the new European requirements of EN624, the Gas Safety Directive.

Since then, the HS1600 developed into the HS1800 and then the HS2000 with further advances made to the motor control and airflow sensing. As a result, this improved reliability and reduced 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.

HS2000E Dual fuel air heater

In September 2008, Propex Heating and Leisure agreed to a strategic partnership with Munster Simms Engineering. Their world-class LEAN manufacturing facilities based in Bangor, Northern Ireland, ensured Propex were well-positioned to continue its growth and R&D.  

Soon after the new partnership came the release of the highly acclaimed combined gas and (main) electric heater, the HS2000E. Whilst a range of underfloor mounted heaters have been developed in these facilities more recently to save valuable internal room inside the vehicle.


In October 2013, Propex moved into a new, larger unit in Ringwood, Hampshire offering more space and improved facilities. 

Where We Are

We’re based in Ringwood¬†in the beautiful¬†New Forest on the Hampshire and Dorset border. Walking distance from the town centre where you’ll find lots of cafes, restaurants, and local amenities.¬†

The golden beaches of Bournemouth and the famed Jurassic coastline are only a short drive away, perfect for any camping trip!

This move offers better facilities including a training room, a fully equipped workshop to carry out installations on Motorhomes and Caravans and a fully stocked showroom.

We stock a comprehensive range of products and spare parts for all the Propex heaters. Plus, a full range of Whale heaters (including the Heat Air and Expanse), submersible pumps, taps and plumbing accessories.

Our heaters are easy to operate at a minimal running cost. With a particular focus on preserving the environment all our heaters run off LPG. A fuel source which has a cleaner burn and produces up to 120x fewer particulates than diesel.

Our services include complete fitting and repair services for all caravans and motorhomes. Propex is also a member of the National Caravan Council (NCC) and operates under the Approved Workshop Scheme (AWS).
