We used to have a campervan that had a Diesel fired heater. The heat it produced was fantastic. I did enquire a couple of years ago to have one fitted to our present campervan. I was quoted £1000+ for fitting a reonditioned heater. So, I was suprised to see thses heaters for under £80!! Vevor posted the heater quickly and was exactly as described. I worked out where to fit it being careful of what was under the floor.The fitting is quite straightforward but the fuel hose supplied is too flexible as the walls tend to pulse as the pump delivers the fuel.I bought some better fuel hose and used the supplied hose on the suction side,which is handy to see the fuel. The handbook is concise if a little difficult as it is presumably translated fron Chinese. It fired up once I had purged the air from the system and pumped out very hot air!! I am having to supplement the hot air trunking because of where I had to fit it as it is too short.
All in all then it seems to be a very good heater and hopefully will last a long time.There is many videos of how to repair thsese heaters and spare parts appear plentiful.
