Hot water for your home using energy from the sun.

Solar ThermalSolar water heating systems use free heat from the sun to warm domestic hot water. A conventional boiler or immersion heater can be used to make the water hotter, or to provide hot water when solar energy is unavailable.By installing the most appropriate and efficient water heater for your household size, water use patterns and climate you can save money and reduce greenhouse gas emissions without compromising your lifestyle.

The benefits of solar water heating.

Hot water throughout the year: the system works all year round, though you’ll need to heat the water further with a boiler or immersion heater during the winter months.
Cut your bills: sunlight is free, so once you’ve paid for the initial installation your hot water costs will be reduced.
Cut your carbon footprint: solar hot water is a green, renewable heating system and can reduce your carbon dioxide emissions

Savings

Solar water heating systems can achieve savings on your energy bills. Based on the results of a field trial, we conducted across a range of household and system sizes, typical savings from a well-installed and properly used system are £65 per year when replacing gas heating and £75 per year when replacing electric immersion heating. Savings will vary from user to user.

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.
