I have used both gas and diesel systems .... Although technically safer to go for a diesel system I have switched to a gas set up and find it far cheaper and less hassel compared to the diesel set up I had ..... Initially I had the Purefreedom hot box which was good but it kept running out the leisure batteries and then their was having to keep servicing it and the daily  cost of the diesel , it started to get too dear for just hot water .... On one occasion I had to service it for about £250+ with changing the burner , plus need two new leisure batteries .... I was staring at about £500 a pop every time it needed doing and the daily diesel cost was about £6 a day using hot all day .....
The gas system now costs about £2.50 a day and no need to service it etc ...... It sometimes is a pain having to keep fetching gas bottles but I am going refillable in Jan so it will be easier and cheaper still with running costs being £1 a day .....
All in all hot is not essential and cold works fine but hot defo makes the working day a bit easier and it comes in for baked on dirt etc ... And at £1 a day I am happy using it everyday for that .....

James what issue are you having with the battery with the diesel heater,mine works fine but I must admit it drains the battery from time to time.

Because the heater kept having to fire up after it had restarted after the water had stopped ie dealing with a customer , disconnecting and reeling in hose this caused a massive drain on the batteries , I did charge them up daily and kept the water recycling back to tank like Purefreedom advised but the batteries ran out about every 9 months and I would have to buy 2 new ones each time and then also service the burner or replace it every year or 18months ...... It was a good heater and Purefreedom are the best company out their imo but I just couldn't face the continual periodic maintenance that was required ..... I paid £3400 for the heater and 4 years later after paying out on about 3 services and daily diesel usage of £6 a day and prob using about 7 new leisure batteries I ended up selling it for £500 and just started using   a gas set up now which is just so much less of a headache ..... As I say though I am not slating Purefreedoms service but for me I just wish I had gone down the gas route earlier but I didn't as I was scare Mongered into believing it was too dangerous.... But used sensibly in the right way you are fine with a gas heater Imo.......
