Although the showers at Le Mans are ok; i am looking for design ideas for this year. I have tried all sorts of designs from cold water storage tank on top of a van (That was dam cold) to solar showers on a high extended rig from the top of a jeep (3.5 meters high, rig not jeep). Last years was the best yet; with a industrial air con evaporater pump, but we had trouble getting enough warm water feed to it. So i am looking for something that can hold 50 to 60 liters of water and either have a heating device in it, or warm the water. I have thought about a thermostatic tea urn handy for lots of morning cuppas and turn it down ideal for showers in the evening, got to be under 2.5Kw. So any ideas would be welcome.
