According to Shuman, up to what percentage of domestic hot water can be provided by solar heating systems? What do Solar hot water systems use to heat water? How much hot water can be produced by solar heating systems in low geographical latitudes? What is a common type of solar water heater? What type of solar water heater is used to heat pools?
Solar hot water systems use sunlight to heat water. In low geographical latitudes (below 40 degrees) from 60 to 70% of the domestic hot water use with temperatures up to 60 °C can be provided by solar heating systems. The most common types of solar water heaters are evacuated tube collectors (44%) and glazed flat plate collectors (34%) generally used for domestic hot water; and unglazed plastic collectors (21%) used mainly to heat swimming pools.
