Please can someone point me in the right direction. I want to create a reliable shower for camping guests in our woodland. This means solar is unreliable because of shade, but we do have plenty of wood that can be used.
I'm concerned about the bits I've read about the explosive issues with heating water, but I'm sure it must be doable especially as I've seen hot tubs heated by thermo syphoning.
Please can someone suggest a good way to heat water that is safe (and possibly fun) for campers to use.
