Abstract: In the present paper a low cost solar active water heating system is proposed to increase the average night temperature and avoid freezing problems inside greenhouses. The system collects the excess of energy in the greenhouse during the day, and returns it at night. The most important part of the system is a plastic bag made of two thin polyethylene films vertically hung inside the greenhouse, that works as a solar collector during the day and as a heat exchanger at night.
