Solar hot water systems
Solar hot water systems are a great way of generating some of your own energy. There are 2 different types of system: flat plate and evacuated tubes. The principle is very simple: when the sun shines, water is pumped through the solar panels and the sun’s energy is used to heat the water. The hot water gets pumped through a heat exchanger which heats the water in your cylinder. The system works in conjunction with your boiler so when there is not enough sun your boiler takes over, meaning you are never without hot water.
Overall, they are cost- effective and a well sited system can reduce your hot water bills by 50% providing up to 70% of your annual hot water needs.
