Contact UsA forced circulation solar system is a solar thermal installation in which water circulates within the circuit driven by a pump. Unlike solar installations with a thermosiphon, this system does not move hot water to the highest point of the closed circuit, but rather makes it go down from the solar collectors to where the storage tank is located.
Solar thermal energy installations with forced circulation have the following elements: Solar collectors are responsible for transforming solar radiation into thermal energy.
In these solar thermal systems, the water that circulates between the solar collectors and the accumulator cannot do so by natural convection since the hottest water is already at its highest point. To do this, you will need a conventional water pump and, therefore, an external electrical power source.
Flow regulator, which will allow the circuit flow to be adjusted. Filter, which will guarantee the durability of the circuit elements. Forced circulation systems are solar thermal energy installations in which a water pump is needed to circulate water.
In many cases it is not feasible to install solar thermal energy equipment to obtain domestic hot water by thermosyphon, given that the location of the solar collectors is often above the tank. This renewable energy system is required in underfloor heating systems.
Better thermal efficiency: the thermal efficiency for heating water is greater than in the solar thermal system with thermosyphon because by being able to regulate the speed of the water that circulates through the solar collector, it can be optimized to obtain the highest thermal performance in accordance with the laws of thermodynamics.
