Such a model of a solar collector is another possibility of budget, but reliable and safe water heating for private houses. The product is patented and already tested in operation.

This collector works most effectively in the warm season (from April to September), which is why this solution is so well suited for use in seasonal houses, cottages, and recreation centers. In the system, ordinary water is usually used as a coolant, but if desired, it can be replaced with antifreeze or propylene glycol. Thanks to the compact design, the installation and dismantling of the seasonal collector is quite simple, as is the connection to additional equipment (for example, a tank).
