How does solar thermal work?
Solar thermal domestic hot water systems work by collectors (solar panels) on the roof, absorbing the radiated energy from the sun. This energy heats the fluid (glycol) which is pumped around a sealed circuit, through the collectors and into a coil within a specially designed hot water cylinder (twin coiled). The hot water is then stored in the cylinder until required, and if need your boiler can heat the water when solar radiation is not available.
Benefits of solar thermal hot water:
Endless amounts of energy with low running costs
No CO2 emissions during operation
Cost savings from using up to 60% less energy to heat your hot water
Reduced consumption of fossil fuels
Solar thermal systems can be integrated into many existing systems
Modern systems work efficiently all year round
There are two types of solar thermal collectors used for solar hot water systems: Flat plate and evacuated tube collectors.
