HiI've got a pure freedom diesel heater if you need any info. I have the 9kw(?) one and use it as single operator. Had some issues over last winter as there are operation tips that pf don't make you aware of when you buy itIt's a great bit of kit but not the cheapest to buy or runI'd be happy to submit a full review if neededSteve
Brodex do diesel alsoI have a couple of their Flame systems.
15 litre tea urn filled with boiling pure water plugged into my cig lighter.fill it up at custies outside tap when it runs out. ppm out of urn 56.does me fine had no complaints. handy for filling up my pot noodle at lunch time also. the van gets a bit steamed up so leave back door open.
