Solar water heaters use the solar energy from the sun to generate heat (not electricity) which can then be used to heat water for showering, space heating, industrial processes or even solar cooling. Solar energy is the primary energy source for our planet as it is responsible for providing energy for plant growth (potosythesis) and providing the warmth that makes our planet habitable.
By using renewable energy sources such as Solar Hot Water, Solar PV, Hydro and Geothermal, reliance on fossil fuels can be greatly reduced. For the average household, water heating accounts for around 30% of CO2 emissions. Installing a solar water heater can provide between 50-90% of a household's water heater energy needs and so reduce CO2 emissions by more than 20%.
