The foundations of our company, WHS Heating Technologies, were laid in 1972 and its main business line is pressure vessel manufacturing. By creating two brands, Ouraset and Yeşilev, for the solar energy market in the 2000s, it has become a strong brand that exports its solar boilers and solar collectors to nearly 30 countries. In this process, it has become the solution partner of various institutions and industrial facilities by realizing many solar projects.
Our company continues on its way with a total of 70 employees, 20 of whom are managers, by adding new ones to the experienced staff that it has been with since the day it was founded. With our administrative centre office in Adana; a production facility with 1,000 m² of indoor space located 10 km from the city centre; and our factory in Aksaray—3,000 m² welded manufacturing, 3,000 m² enamel coating, 6,000 m² indoor area, 15,000 m² stockyard—we are established on a total area of 21,000 m².
Our company continues to grow and increase its capacity without compromising the quality of its developing technology and product range by keeping the foreign market research at the forefront. You can see our brand on buffer tanks, solar tanks, single-serpentine/double-serpentine and heat-pump boilers, more than 150,000 of which are operating in domestic and international markets.

As a solar company, our mission is to accelerate the world's transition to clean, renewable energy. We aim to provide high quality solar solutions that are not only sustainable but also cost-effective for individuals and businesses alike. Through our innovative approach and latest technology, we are trying to give our customers the power to increase their energy independence and improve their overall quality of life. We continue to progress without pause, aiming to carry our country to the top of the energy sector and to strengthen the confidence we have gained. We always strive to channel our energy into moving ourselves forward. And you?
Our experience in solar water heating systems drives us to constantly innovate in order to meet customer needs and their important expectations such as energy efficiency, ease of use and safety, believing that everyone has the right to benefit from the energy of nature. In addition, designing and producing environmentally friendly products—while remaining future-oriented and taking necessary precautions—is another crucial goal. Producing innovative, environmentally friendly boilers that meet our customers’ key expectations—energy efficiency, ease of use, and safety—is central to our vision. By always keeping customer satisfaction at the highest level, we aim to reach the leading position in our sector and offer a sustainable future to our employees.

Solar energy is very important in terms of environmental policies. Unlike fossil fuels, solar energy is produced from natural sources and works with zero emissions. Therefore, it plays an important role in the fight against environmental pollution and climate change. Unlike fossil fuels, solar energy does not release greenhouse gases such as carbon dioxide, sulfur dioxide and nitrogen oxide into the atmosphere. Therefore, solar energy can generate electricity without polluting the environment and provide energy without causing global warming. Solar energy is also a sustainable energy source. Unlike fossil fuels, solar energy is inexhaustible. This means that using solar energy for energy supply can also provide a sustainable source of energy for future generations. As a result, solar energy plays a very important role in terms of environmental policies. In order to fight environmental pollution and climate change and to provide a sustainable energy source, the use of a clean and unlimited source such as solar energy is important.
Solar energy quality policies are policies that set certain standards and quality control processes in the production, distribution and use of solar energy. The purpose of these policies is to ensure that solar energy systems are safe, robust and high-performing. Solar power quality policies require manufacturers and suppliers to implement certain testing and certification procedures to ensure compliance with certain quality standards. These procedures include testing and quality-control processes to determine the quality of solar-panel components. There are guidelines that require certain quality standards to be applied during the installation and maintenance of solar systems. This ensures safe, reliable and high performance operation of the system. Solar energy quality policies have been developed by various standard organizations at national and international level. These include organizations such as the International Electrotechnical Commission (IEC), the International Organization for Standardization (ISO) and the European Committee for Standardization (CEN). As a result, solar energy quality policies play an important role in ensuring the quality of solar energy systems. nforcement of these policies ensures that solar systems are safe, reliable and high-performing, which benefits both consumers and industry.
