You will need to have an unshaded, sunny area to install the solar collectors, either on a pitched roof, flat roof or, for evacuated tubes, a wall with a Southerly aspect. If installing the collectors on the roof, it will need to be structurally sound. You will also need space for a solar hot water cylinder, which could be large than a standard cylinder. If you have a combi boiler, you may need to change your boiler to a system or heat only boiler to be compatible with solar thermal. We will be able to advise whether your property is suitable for a solar thermal system.
