Solar hot water

Solar thermal and, especially, active Solar Domestic Hot Water (SDHW) heating is a well-established renewable energy system. It can be one of the most cost-effective renewable energy systems available.
It is appropriate for both residential and non-residential applications. For a single typical house, for instance, a suitable water heating system would occupy 2.5-4m2 of roof space. The cost would be £1,500-10,000 for a flat plate system that will provide around 50% of the typical hot water demand, and up to £5,000 for an evacuated tube system that will provide around 60%.
Solar hot water can be applied cost-effectively in a number of non-domestic building types, such as hospitals, nursing homes and leisure facilities, which have high demands for domestic hot water. Solar hot water systems are not so cost-effective in commercial buildings, where the demand for hot water is lower.
The main conclusions being that most systems are technically proven and will provide a significant contribution to hot water demand if correctly installed. Installer training and accreditation schemes supported by the DTI have helped allay fears of poor quality installations, and this is on-going.
Solar thermal systems normally operate with a back-up source of heat.The solar system pre-heats the incoming cold water, which is topped up by the back-up heat source when there is insufficient solar energy to reach the target temperature.
Solar collectors are best mounted at an incline with a southerly orientation, although orientations between south-east and south-west are acceptable. With increased collector area, orientations between east and west are also acceptable. Collectors can also be mounted on south-facing vertical walls or horizontally, so that a large proportion of the building stock is suitable for solar thermal systems.
There are four main types of solar collector that can be used in Solar heating system. These are:
1. Evacuated tubes.
2. Glazed selective surfaced flat plate.
3. Glazed non-selective surfaced flat plate.
4. Unglazed plastic collectors (mostly used for swimming pool heating).
