Do your bit for the environment and invest in a SolarVenti Solar-powered Dehumidifier to keep your holiday home or caravan free of damp and mould.

The units activate whenever there's enough light to power them through their solar cells. They push warm and dry air into an enclosed space that may be unoccupied for long periods of time, to keep it fresh and mold-free.

So if you've docked your boat for the winter, or parked up your caravan, you can now make sure that it's habitable the next time you want to use it.

The largest units can even be used for second homes and buildings up to 140 square meters in size, giving you peace of mind and saving on heating bills and wasted journeys to air the place.

The smallest model measures just 53 x 53 x 10cm, and is easy to install with its conventional flex hose that is directed into the space to be kept dry.

Prices start at £323 for the smallest of the five units and go up to £1216 for the largest.
