Solar Thermal Hot Water Systems

According to the Energy Saving Trust installing a solar hot water system in your home is the most cost effective way to provide maximum energy for minimum cost.

Solar thermal systems collect and convert energy from the sun’s rays using solar collectors (panels) positioned on a roof or south facing space. Solar fluid in the system pipe work is heated up and circulated through a solar coil in the base of a specially designed hot water cylinder, which then transfers the heat to the hot water storage cylinder. The temperature in the collector is constantly monitored by an electronic controller and compared with the temperature in the cylinder – when the temperature in the collector exceeds the cylinder by a pre-set amount the pump is activated to circulate the heated solar fluid through a heat exchanger located towards the bottom of the of the cylinder. In the winter months, when the days are shorter and the sun’s rays less intense the useable energy is still significant but reduced. This means that an additional heating source such as an immersion heater or a conventional boiler is still necessary.

Installation

The collector is commonly mounted on a southwest to southeast facing roof but east/west systems can be located on a flat roof or gable-mounting frame to maximise solar gain.

We offer various types of systems all of which are from market leaders and renowned manufacturers. For further information and specification please click manufacturers logos.
