The sun’s rays have been warming the earth for approximately 5 billion years. In just 30 minutes, it provides us with more energy than the entire human race can consume in a whole year. And it will continue to do so for the next 4 billion years. Best of all: the sun doesn't charge us for the energy it provides. The Paradigma solar heating systems allow you to use solar energy for effective water heating and backup heating in your house. Paradigma’s CPC evacuated tube collectors are among the most powerful on the market.
How Paradigma evacuated tube collectors work
Thermos flasks can keep coffee and tea hot for hours because there is a vacuum insulated intermediate layer between the double vessel walls. With the two concentric glass tubes, Paradigma evacuated tubes also form a hermetically sealed space that is vacuum insulated. In addition to this, the outer surface of the inner tube is coated with a highly efficient, environmentally friendly absorber coating. This converts incident sunlight almost completely into heat and radiates almost no heat. The inner tube becomes hot while the outer enclosing tube remains cold.
To also irradiate the side of the evacuated tube that is not facing the sun, the optimised geometry of a highly reflective, weather-proof CPC (Compound Parabolic Concentrator) reflector concentrates direct and diffuse sunlight onto the absorber from almost all directions. This increases the efficiency of the evacuated tube collectors compared to conventional collectors. Especially under unfavourable conditions, e.g. during autumn and winter, when the sky is overcast, during morning and evening sun and when the roof surface does not face south.
The evacuated tubes are slid onto a heat transfer unit. Close fitting heat transfer plates inside each evacuated tube conduct the solar heat to a U-shaped pipe through which the water or a frost protection agent-water mixture (depending on the system) flows. When the required temperature is reached, the pump in the solar circuit is activated by the controller and transports the heat to the hot water storage tank or the heating system. The great efficiency of the CPC evacuated tube collectors thus facilitates convenient provision of sufficient heat.
The Paradigma Aqua solar heating system is special
Standard solar heating systems run on a frost protection agent-water mixture which transports the heat from the solar collector to the hot water storage tank. By introducing the innovative Aqua solar heating system, Paradigma has succeeded in making the switch to solar energy even easier. The principle is equally simple and ingenious. The sun sends energy and the system stores it. The heat is transported by pure water. You do not have to replace your storage tank. Of course, the reliability of the innovative Aqua solar heating systems has been proven for you. Tests at the University of Stuttgart's Institute for Thermodynamics and Thermal Engineering have confirmed their faultless, safe and reliable operation. The Paradigma Aqua solar heating system package was awarded the 2006 german prize for outstanding innovative craftsmanship.
