You wouldn't guess that in the tropics having hot water was so desirable, but at our elevation, it gets quite chilly for me in the evenings. During the rainy season the nights can get particularly cold and if you've been in the rain working, a rejuvenating warm shower is just the ticket!
Over the years we have trialed two different types of hot water systems: composting hot water and solar hot water. I've personally installed and used both systems and would like to share what I've learned.
