What is an evacuated tube?
Apricus uses an "evacuated" tube design for their solar hot water systems. High quality borosilicate glass expels air from within the tube creating a vacuum.
This vacuum is a highly efficient insulator making it the ideal choice for solar hot water systems in areas that experience low temperatures such as Colorado.
How do Apricus Solar Thermal Systems Work?
Apricus Solar Collectors convert energy from the sun into usable heat and solar hot water.
- The absorber coating on the inner glass tube absorbs sunlight and converts it into heat.
- Steam forms inside the heat pipe which transfers heat rapidly up to the manifold.
- A pump circulates water or heat transfer fluid through the header pipe, carrying heat back to the storage tank so gradually throughout the day the tank is heated up.
Solar Hot Water System Components
The Apricus Solar Collector is comprised of four main parts:
- The Evacuated Tube (ET) which absorbs solar energy and converts it to usable heat. The vacuum between the two glass layers insulates against heat loss.
- The Heat Pipe (HP) is a copper vacuum pipe that transfers the heat from within the Evacuated Tube up to the manifold.
- The Manifold is an insulated box containing the copper header pipe. The header is a pair of contoured copper pipes with dry connect sockets that the heat pipes plug into.
- The Mounting Frame which is strong and easy to install with various options to match different mounting methods.
