Easier and cheaper: the gravity solar collector system
Using the gravity solar collector system, you can really produce free hot water for two thirds of the year!
The Gravikol solar collector system we recommend has up to 40% lower material costs > than traditional pump systems, and because of its simplicity, you can even build your solar collector system with your own hands!
The operation of the gravity solar collector system
The gravity solar collector system is based on a simple but effective principle that uses the upward flow property of the warmer liquid. As the temperature in the collector rises due to the sun, the liquid starts to flow upwards. The hottest liquid enters the heat exchanger, where it transfers its heat to the water in the storage. After that, the cooled liquid returns to the collector by gravity to heat up again and the cycle repeats.
It is important to note that a gravity system does not require a pump to provide fluid flow. This solution has several advantages:
- Simplicity:The absence of a pump makes the system less complicated and easier to install.
- Reliability:There is no chance of pump failure, so the system is more reliable.
- Energy saving:Since it does not require electricity to operate the pump, the gravity system is more energy efficient.
- Efficient heat transfer:The hottest liquid always enters the heat exchanger, so the heat transfer is more efficient.
The gravity solar collector system can be an ideal choice for households that:
- They are looking for a simple and reliable solar collector system.
- They want to save energy.
- They don't have enough electricity to operate the pump.
When installing the gravity system, it is important to consider the placement of the collector and the storage container. The collector must be mounted on the roof so that it faces south and receives maximum sunlight. The container must be placed above the collector to ensure gravity flow.
The gravity solar collector system is an efficient and environmentally friendly way to produce domestic hot water. The system requires low maintenance and has a long service life.
- Simpler: does not require the installation of a pump and control. Therefore, it is significantly cheaper, even in the case of a small system, it means HUF 80-100 thousand savings!
- More efficient: instead of human intervention and artificial circulation, the laws of physics ensure that as much heat as possible is transferred from the solar collector to the storage.
- Its operation is completely free: unlike pumping systems, it does not require electricity. The energy cost of the pumping system is the collector at least 25% of the value of the energy produced by.
- Requires maintenance only in exceptional cases: the system is so simple that nothing can go wrong.
- Flexible: our goal is to present practical, highly utilized small systems. Therefore, we recommend the system primarily for the production of domestic hot water.
