A solar hose is coiled along the roof of the trailer which houses the ablution facilities, warming the water inside it during the day, ready for use in showers and basins at night.
The only cost involved is for the initial outlay of the hose which amounts to about $110 per 100 litre of water, and is thus a much cheaper option than the conventional heating with gas.The hose consists of a black jacket of warp and weft high-tenacity polyester filament yarn with an integrated inner and outer coating of polyvinyl chloride and nitrile. It heats water to about 40C by mid-afternoon. If higher temperatures are required, it can be further heated by gas, which is still cheaper than heating the water from normal storage temperature, says the designer of the hose, Dylan Tudor Jones of Solar Heat Exchangers (SHE).
The design is an adaptation of a similar hose which was developed in France to provide poor African communities with affordable hot water.
Trailer and hose can be custom-made to any specification to be used as mobile ablution facilities or in more permanent applications by farmers, bushlodges and beach hotels.
