Bought this from @Dicky last winter, never got round to doing anything with it and have since sold my bus... oh well. NOW SOLD Here's the text and photos from the original ad: X1 Propex (Hotbox) heater. Just removed from my van due to upgrade. Comes with stat, short lengths of aluminium inlet and exhaust ducting and hot air duct (may have a vent too for the hot air outlet but will need to have a look). The model is still supported by Propex. The unit is working fine but with but if you did want it checked out then I believe Propex will do this. The heater is rated at 1600watts and warms up the van in just a few minutes. Runs on propane or butane (Calor/Camping gaz) and I can let you have a camping gaz bottle with it if you needed one (empty!). Extra ducting etc available from Propex: http://www.propexleisure.co.uk/cat/propex-spare-parts/x1-x3-hotbox Picture below shows it running on the bench.
