Solar water heating is arguably the most energy-efficient way of producing domestic hot water, as the primary energy source " sunlight " is free. Solar water heating has been used for many years in warm sunny climates, but it can work in locations as far north as Canada and Northern Europe. If you have a large family or use large quantities of hot water, a solar water heating system may be a cost-effective option. While the equipment has a higher initial cost than other types of water heaters, the energy savings can more than offset the cost over the life of the system.
