Solar Thermal Hot Water can save around 70% of your energy costs
Solar water heating systems, or ‘solar thermal’ systems, use heat from the sun to warm your hot water. A standard boiler or immersion heater can be used to make the water hotter, or to provide hot water when solar energy is not available. Using the abundant and free energy from the sun can save you money on your fuel bills.
Hot water when you need it
Solar thermal systems work through the year, though you will need to heat the water further with a boiler or immersion heater during the colder months.
Reduced energy bills
Sunlight is free, which is why solar energy is always a sensible choice. After the initial installation costs, your hot water costs will be reduced every year.
The green choice
Solar hot water is a green, renewable heating system and can reduce your carbon dioxide emissions and carbon footprint, making it an excellent choice for the environment.
How does solar thermal work?
Solar energy is absorbed by the panels and is used to pre-heat the water in a hot water storage cylinder. This reduces the amount of fuel needed to bring the water to a hot enough temperature by your regular boiler. Most solar systems in the UK are ‘indirect’, which means the liquid in the panels is not what comes out of the taps but is actually a mix of water and antifreeze, and the heat it absorbs is transferred to the water in the hot water cylinder by a copper coil.
