What is a forced circulation solar system?
A 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.
How much power does a solar water heater pump use?
This publication introduces calculations of circulation pump power for solar water heater, forced circulation system. The theoretical power is estimated as 0.5 Watt, while the nominal power of the relevant pump is 6 Watt. Energy consumption of such pump is 25 kWh/year. The required water flow is 2 liters/minute and the pump's head is 1.5 meter.
How do solar thermal systems work?
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.
Can a solar thermal energy system produce hot water by thermosyphon?
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.
Why is solar energy required in underfloor heating systems?
This renewable energy system is required in underfloor heating systems. 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.
What are solar thermal energy installations with forced circulation?
Solar thermal energy installations with forced circulation have the following elements: Solar collectors are responsible for transforming solar radiation into thermal energy.
