Solar thermal water heating is a well-established renewable energy system in the UK and abroad. It is also one of the most cost effective renewable energy systems available.
The solar system is intended to be used as part of the hot water supply to sinks, wash hand basins etc. The solar system heats water by means of a solar panel array, typically located on the roof, ideally with a southern orientation. The solar panels may also be mounted within a South East to South West range with good effect. Rotating tubes can also be provided to ensure correct alignment.
Water will be circulated throughout the roof mounted solar panels to gather heat and will be passed through a coil within a cylinder in the plant room. Mains water enters the cylinder and is heated by the coil. The heated water then leaves the cylinder and is piped to its final draw off point. The cylinder will be fitted with a back up energy source via an LTHW coil. If there is not enough power to fully heat the water to the desired temperature, then a thermostat will activate the back up energy source.Heat meters will be provided linked from the system to the BMS to allow monitoring of energy savings.
