One of the most cost-effective ways to include renewable technologies into a home or building is by incorporating solar hot water.
A typical residential solar water heating system reduces the need for conventional water heating by about two-thirds. It minimizes the expense of electricity or fossil fuel to heat the water and reduces the associated environmental impacts. In Europe and Asia a solar heating system is required by building codes to be included in any new home. This trend is quickly being adopted to North America as can be seen in Hawaii's new building codes requiring solar thermal heating.
Solar water heaters provide you and your family environmentally friendly clean energy to heat domestic hot water, swimming pool heating, homes and Industries. The Sun's solar energy heats a fluid (water or glycol) then transfers that solar heat directly or indirectly to heat water.
The initial cost can be slightly higher than a conventional gas or electric water heater, but the fuel... is free energy from the Sun... And with the many grants and low interest loans available, a solar heating system can actually cost less than a conventional heating system upfront!
