Solar Thermal

    How it works

    Our Solar Thermal installations utilise the heat from the sun to increase your water temperature as a result of the sun's radiation being absorbed. The resulting warm water is then routed to your hot water tank. Any shortfall in the desired water temperature is then compensated for by your heating system, whether it be an immersion heater or boiler. This means that your heating system is doing less work, thereby saving you money!

    Naturally these systems work more efficiently during the summer months, where it is possible to generate up to 85% of your daily hot water. However, it will also have an affect during colder months, ensuring that it is constantly helping with heating costs.

    In a "close-coupled" SWH system the storage tank is horizontally mounted immediately above the solar collectors on the roof.solarthermal

    No pumping is required as the hot water naturally rises into the tank through thermosiphon flow. In a "pump-circulated" system the storage tank is ground- or floor-mounted and is below the level of the collectors; a circulating pump moves water or heat transfer fluid between the tank and the collectors.

    imgBSWH systems are designed to deliver hot water for most of the year. However, in winter there sometimes may not be sufficient solar heat gain to deliver sufficient hot water. In this case a gas or electric booster is normally used to heat the water.
