Solar Water Heaters


Solar Hot Water

One of the most cost-effective ways to include renewable technologies into a building is by incorporating solar hot water. Most systems can pay for themselves in 2 – 3 years. Solar water heaters use the sun to heat either water or a heat-transfer fluid in the collector. Heated water is then held in the storage tank ready for use, with a conventional system providing additional heating as necessary. The tank can be a modified standard water heater, but it is usually larger and very well insulated. Solar water heating systems can be either active or passive, but the most common are active systems.
