What is Solar Thermal?
Solar Thermal is a clean and highly efficient means of using renewable energy from the sun to provide the hot water used in the home. The basic principle is easy to understand. If you unroll a garden hose on the ground and leave it exposed to the radiant heat of the sun, in a short time the water in the hose will become warm.
Solar thermal collectors work in very much the same way, only more efficiently. Usually, but not exclusively, roof-mounted solar collectors will be connected to one of the coils of a twin-coil cylinder using a sealed circuit containing a special glycol/water solution. This fluid not only withstands the high temperatures in excess of 200°C in the collector on a summer day, but also will not freeze in temperatures down to –25°C. The pump in the system circulates the heated fluid from the panel to the cylinder where the heat is transferred to the stored water through the lower coil.
Making a difference
Renewable energy has a key role to play in reducing CO2 emissions and, in particular, the installation of solar technology is an effective way of reducing a building’s carbon footprint. Solar technology is great for the environment, as it has no emissions and is assured for the next 4 billion years! It might also be worth noting that incorporating solar into a property is likely to increase its value. If you look at it in another way, houses with solar are only marginally affected by increasing fuel prices, therefore making them an extremely attractive option to potential buyers.
The benefits of Grant Solar Thermal
Installing a Grant Solar Thermal System has many advantages. Apart from reducing the amount of fossil fuels used, and the resultant savings in annual fuel bills, the reduction in harmful emissions will help minimise the long-term effects on the Earth’s climate. All components within the Grant Solar Thermal Range are regularly tested under simulated real conditions to ensure customers receive a product of the highest quality and reliability.
Grant Solar Thermal collectors incorporate self-cleaning glass and can be installed on sloping roofs using either an on-roof or in-roof mounting system and also on flat roofs if required.
