We aren't just stocking the Propex HS2000, either - many of our customers need something a little different, which is why we're also stocking the HS2000E, HS2800, and the Propex HS2211.
The Propex HS2000E works on either gas or mains electricity, which is ideal if you're going to be camping in places with a mains hook-up, or you don't have a 12v leisure battery installed; while the HS2800 is simply a larger version of the HS2000, more suitable for larger campervan conversions, motorhomes or even boats.
The Propex HS2211 is mounted beneath the vehicle, rather than inside it. This is ideal if space is at a premium within your campervan, and you just can't find space inside a cupboard or beneath a bed to fit a Propex HS2000.

More about Propex
Propex have been designing and manufacturing their heating systems in the UK for more than 35 years. All of their air heaters and water heaters comply to all UK and EU safety standards, and their commitment to quality and safety remains strong to this day.
We first added the Propex HS2000 to our range here at Just Kampers when our Sales Director, Shaun, was looking for a way to keep his VW T2 Bay warm while he drive it to JK HQ during the winter months. He bought himself one, fitted it himself, had it checked over by a registered gas technician, and hasn't looked back since!
Shaun was so impressed with the HS2000 that we added it to our range, and have added more and more Propex heaters and accessories since then.
Propex are based in Ringwood, which is only about an hour away from JK HQ in Hampshire, and it's great to see that their commitment to creating excellent quality products in the UK lines up with our own.

How To Install A Propex Heater To a Campervan
Frequently Asked Questions about Propex Auxiliary Heaters
What is the fuel consumption of the Propex HS2000 & HS2800 heater?
For the HS2000, the continuous fuel consumption is roughly 142 grams of LPG (either propane or butane) each hour. In real-world applications (regulated by a thermostat), the actual fuel usage tends to be less.
For the HS2800, the continuous fuel consumption is around 225 grams per hour.
What is the heat output (and input) of the HS20000, HS2000E and HS2800 heaters?
HS2000: Heat input is approximately 2.1 kW, with a net useful heat output of about 1.9 kW (indicating system efficiency).
HS2800: Heat input is roughly 3.0 kW, and the net output is around 2.8 kW.
The HS2000E (which uses both gas and electric) in electric mode provides selectable outputs of 500 W, 1 kW, and 2 kW, with a maximum current draw of approximately 9 A.
How much electric current do Propex heaters draw?
In gas heating mode, the HS2000 consumes approximately 1.4 A continuously, while its standby consumption is about 0.04 A.
The HS2800 uses roughly 1.9 A continuously when operating in gas mode.
In electric mode (230 V) with the HS2000E, the motor speed and current draw of the heater adjust according to the power setting, reaching a maximum of approximately 9 A.
How long will a gas bottle last?
By utilising continuous run figures (which represent the worst-case scenario), you can make estimations:
For HS2000: A 3.9 kg propane cylinder provides approximately 27.5 hours of continuous run time. A 13 kg propane tank offers around 91.5 hours of continuous operation. In practice, since the heater cycles on and off, you will typically enjoy many more hours of effective heat.
For HS2800: A 3.9 kg propane cylinder yields about 17.5 hours of continuous run time. A 13 kg tank delivers roughly 58 hours of continuous operation.
Can Propex heaters be run while driving?
Absolutely! Propex provides a "Vehicle In Motion" (VIM) bracket option, allowing the heater to operate safely while the vehicle is moving, provided it is installed correctly.
Nonetheless, it's crucial that the flue and intake are properly secured, and that the installation adheres to the safety regulations applicable in your area.
How many heat outlets (ducts) can be used?
For the HS2000 and HS2000E models, you can connect up to 3 outlets, provided that the total duct length stays within the suggested limits (for instance, total ≤ 5 m and the first outlet ≤ 1.5 m).
Similarly, for the HS2800, you can also use the same multi-outlet setup, as long as you adhere to the duct length restrictions.
Where can I install a Propex heater in a campervan?
Typical mounting spots are:
• Inside a cupboard or bed-box (with a downward flue through the floor).
• Under a bench.
• Under the driver's seat or passenger bench seat, provided there is adequate space and airflow around the heater.
Caution: The heater should never be mounted vertically on its nose or end, or upside-down. It can be placed on one of its sides as long as the electronics cover and gas connections are easily accessible.
How loud is a Propex heater?
Propex units are made to operate quietly. The internal fan runs effortlessly with balanced blades, and the microprocessor control keeps the fan speed steady, even with supply variances between 10V and 15V.
However, you can still hear the airflow and fan hum when you're close by — a lot of installers choose to enclose or box the heater to reduce noise in living spaces.
What safety features do Propex heaters include?
The unit is room-sealed — all combustion air is drawn from outside, and all exhaust is expelled externally
Built-in electronics monitor flame presence, case temperature, combustion airflow, gas valve operation, and voltage — if any parameter becomes abnormal, the heater shuts off and indicates a fault via flashing red LED on the thermostat control.
The system is certified to European appliance & EMC standards.
Still, always install carbon monoxide and explosive gas detectors in your van as an extra safety precaution.
Which model should I choose (HS2000 vs HS2800 vs HS2000E)?
HS2000: Perfect for most campervans or smaller vans — it's efficient, compact, and can provide around 1.9 kW of useful heat.
HS2800: Great for larger vans, poorly insulated setups, or chilly climates — it has a higher output of about 2.8 kW.
HS2000E: Ideal if you need flexibility — it can operate on LPG or mains electric (230 V). This is handy at UK sites with mains hook-ups available.

If you're unsure, opting for a higher output unit gives you some extra leeway (you'll likely just use it at lower thermostat settings most of the time).
