A Filsol solar water heating system is designed to save you money and help the environment by converting the natural sunlight that hits the solar panels into heat in your hot water cylinder.
The solar water heating system will work alongside your boiler (or alternative heating source) to provide you with free, clean energy to heat a significant amount of your total hot water requirements throughout the year.
Solar panels (or collectors) are fitted to your roof where they soak up and retain heat from the sun’s rays. A liquid is pumped through the solar panel which absorbs the heat and carries it to the cylinder. This heat is then transferred to the water in the cylinder which it warms up throughout the day for later use as required. A simple plumbing system of pipes connects the cylinder to both the solar collectors and your hot water supply.
The hot water cylinder is typically designed so that the boiler (or alternative heating source) can only heat the top section of the cylinder, whereas the solar panels can heat the whole cylinder.
The solar water heating system is designed to operate in conjunction with your primary heating source to provide you with continuous hot water as you need it. On days where there is not enough light, the solar panel will warm the cylinder, and the boiler (or alternative) will raise the temperature to the setting on the cylinder thermostat.
On days with plenty of light, the solar panels can heat up the whole cylinder. Either way, your hot water supply will not be affected and you can continue to use hot water in the usual way. The solar water heating system will operate automatically and requires no action from you to make it work.
Depending on the amount of hot water you use, the solar system should provide 50-60% of your hot water averaged over the course of the year.
