Solar Thermal

Solar thermal systems, use free heat from the sun to provide domestic hot water. Solar water heating systems use solar panels, called collectors, fitted to your roof. These collect heat from the sun and use it to heat up water which is stored in a hot water cylinder, a conventional boiler or immersion heater can be used to provide hot water when solar energy is unavailable.

The benefits of solar water heating

  1. Hot water throughout the year. The system works all year round, though you’ll need to add heat to the water cylinder with a boiler or immersion heater during the winter months.
  2. Reduced energy bills. Sunlight is free, so once you’ve paid for the initial installation your hot water costs will be reduced.

Is solar water heating right for your home?

Things to consider

Do you have a sunny place to put solar panels? You’ll need around five square metres of roof space which faces East to West through South and receives direct sunlight for the main part of the day. The panels don’t have to be mounted on a roof however. They can be fixed to a frame on a flat roof or hang from a wall.

Do you have space for a larger, or an extra, hot water cylinder? If a dedicated solar cylinder is not already installed then you will usually need to replace the existing cylinder, or add a dedicated cylinder with a solar heating coil.

Is your current boiler compatible with solar water heating? Most conventional boiler and hot water cylinder systems are compatible with solar water heating. If your boiler is a combination boiler (combi) and you don’t currently have a hot water tank, a solar hot water system may not be compatible.
