In recent years there has been a significant increase in the development of alternative energy solutions based on solar energy, which is why implementation costs have become increasingly attractive to end users.
Pressurized solar collector systems (split type) are complex installations that can operate 12 months / year and which have in their component the solar collector (mounted on the roof) a pumping unit, a control unit, boiler with single coil or double coil, vessel expansion and a full set of sensors and safety valves. It uses an antifreeze that circulates in a closed circuit between the solar collector and the coil in the boiler. This antifreeze takes the heat produced by the collector and transfers it to the water in the boiler through that coil.
Among the advantages of this model is the fact that if the boiler is one with double coils, it can be used to contribute to the heating of the house. Also, heat-pipe tubes can be used in the event that one of the tubes breaks, the solar panel can still function until this tube is replaced.
This installation can be used together with the boiler / electric boiler and is dependent on electricity but its maintenance is not available to everyone and therefore in case of a failure it is necessary the intervention of a specialist.
