Thermosyphon solar collectors

Thermosiphon collector

— thermosiphon is a specific type of vacuum collector (see the relevant paragraph). They are designed for use in the warm season, from spring to autumn. In winter, when the temperature is below zero, the water in such collectors freezes and they become useless.

On the one hand, thermosiphons are less versatile than other vacuum models: they are limited in time of the year and cannot be used for heating (in cold weather, when heating is most relevant, the collector becomes useless). On the other hand, such devices have certain advantages: they are simpler, cheaper, more compact and easier to install. Among the best options for using thermosiphon systems are summer cottages, hotels and other places where people stay mainly in summer.
