Calpak History

1975

Calpak BP is established in Greece as a subsidiary of British Petroleum, with the aim of making solar energy sustainable and accessible to all.

1977

The production of Calpak Neo, the first solar water heater system with a horizontal closed circuit tank, begins. It is the starting point of a story full of technological innovations.

1979

A state-of-the-art solar laboratory is being created at Calpak’s facilities, the first of its kind in the entire European industry. Its purpose is to facilitate the precision measurements necessary for the further development of solar technology.

1981

Calpak Mark2 enters the production line. This thermosiphonic system is a huge commercial success, helping to change the perception of solar thermal energy across Europe.

1985

Calpak is now developing into a European leader in large-scale solar thermal installations as well, mainly covering the hot water needs of hotels through integrated high-tech solutions.

1989

Calpak becomes independent from BP and continues its highly successful course as a purely Greek company

1993

Calpak acquires an export profile, taking part in almost all major international exhibitions of the heating industry. For the first time that year, its exports account for more than 50% of its total turnover.

1998

With the aim of optimal quality and increasing production capacity, a large investment plan is being implemented to expand the Company’s factory and renew its mechanical equipment.

2002

Calpak launches high-tech production of vacuum collectors.

2003

The Company starts the production of selective collectors with laser technology bonding.

2004

Calpak completes the first combined installation of solar systems for space heating and hot water.

2005

Calpak is recognized as one of the top 10 companies in Europe that certify their collectors with the SolarKeymark quality mark.

2007

Calpak’s exports have expanded to all 5 Continents.

2008

The production of CL, a complete line of high-quality floor-standing hot water tanks, with a capacity of up to 9000 liters, begins.

2010

Calpak enters into long-term agreements with the National Scientific Research Center “Demokritos”, the University of Patras, the Technical University of Athens, the Center for Renewable Energy Sources and other scientific and technological bodies. These agreements significantly strengthen the capabilities of the Company’s Research & Development sector.

2013

Significant investments are made towards the technological improvement of the productions means of Calpak. Robotic technology is now widely used in our factory enabling unprecedented precision in the welding processes and increasing a lot the maximum capacity our production.

2014

The innovative new series of solar water heating systems and flat collectors Mark4, made of aluminum, is experiencing tremendous success due to its groundbreaking design and superior quality.

2017

Calpak R&D laboratories present a new class of fresh water tanks. The high-performance X-Flow technology allows the storage and transfer of thermal energy with 99% efficiency, thus offering endless hot water providing savings!

2019

The openining of Calpak’s new factory marks the beginning of a new era in the design and production of high-quality solar systems. This state-of-the-art facility is equipped with the latest, most advanced rovotic technology, ensuring precision and efficiency in every step of the manufacturing process.

2021

The production of Prisma has begun. This innovative collector stands out due to the use of cutting-edge materials in its construction, along with a fully automated production platform that enhances efficiency and precision.

2022

With the launch of the Mark5, Calpak introduces its new flagship product, setting a new standard in the strength, durability, and design of solar water heaters.

2024

Introducing the “Lean Manufacturing” philosophy into our production process to deliver greater value to our customers.
