Propex HS2000:
The Gas Workhorse
Technical audit of the UK's favourite LPG heater. Clean combustion, low power draw, and "install-and-forget" reliability.
Introduction
The Propex HS2000 is an automatic, thermostatically controlled blown air heater fuelled by Propane or Butane gas (LPG). It is the most popular gas heater for campervans and motorhomes in the UK, prized for its simple design and high reliability.
While diesel heaters have dominated the market recently, the Propex remains the choice for those who already have a gas installation for cooking and want a cleaner, lower-maintenance heating solution.
Technical Specifications
Fuel Efficiency
"How long will my gas bottle last?"
The HS2000 consumes approximately **142 grams of gas per hour** of continuous running. In a real-world scenario where the thermostat cycles the heater on and off, a standard 6kg Calor Propane bottle can provide between 40 and 60 hours of heating. For a weekend trip, this is more than sufficient.
Reliability & Care
One of the biggest advantages of the Propex over diesel heaters is the lack of "sooting." Because gas burns so cleanly, there is no carbon buildup on the glow plug or in the combustion chamber.
As a result, a Propex HS2000 requires almost zero maintenance beyond an occasional check of the intake and exhaust pipes for obstructions (like spider webs or mud).
Final Assessment
"For the DIY builder who wants a simple, quiet, and British-made heating solution, the Propex HS2000 is unbeatable. It is the 'honest' heater — it doesn't have the fancy digital screens of a Webasto, but it starts every time and provides a dry, comfortable heat."
