Solar Shower CRM® produces and stores hot water in its own column with different capacities (20L, 30L, 40L & 60L). It uses solar collection and thermal conductivity (the solar collector is made out of aluminium, magnesium and polyester with some metallic particles) to heat the water up to 60ºC after just a short exposure to direct sunlight. The shower can be used several times throughout the day and all this without any energy consumption. Unlike other solar devices, this shower makes use of the ambient temperature as well, so that it can be used on cloudy or overcast days.
