You'd be supprised how little sunshine one of these needs to heat up! Used a simillar one in the South of France last summer, and the water was TOO hot to shower under (had to top it up with cold water)
Although you may not have the same problems in Old Blighty, it's just great to have 'shower' available when returning to your Canvas Nest, be it festival mud or forest bugs you need to shake off to get a good nights sleep! :-)
