Renewable Technologies – Solar Thermal
What is solar thermal?
Solar thermal systems allow householders to utilise the power of the sun to provide hot water to their home. With zero CO₂ emissions, solar thermal is an environmentally responsible alternative to traditional energy sources, and can be easily incorporated into a new or existing heating system.
Solar collectors work throughout the year, even in the winter! They operate in both direct and diffused sunlight so they work even on cloudy days.
The basic principles
Solar thermal collectors efficiently extract the energy from the sun and transfer it into a home’s hot water system. Roof-mounted solar collectors are connected to a system which contains a special glycol/water solution. While passing through the collector, the fluid is heated up and then circulated from the panel through to a cylinder where the heat is transferred to produce hot water.
