Calpak Solar Water Heaters

Solar Water Heater is the most widespread application for hot water production with the use of solar energy. The main reasons for the success of the solar water heater in the global marketplace are its low cost, quick payback, easy installation and reliable operation.

The use of emerald enamel as a corrosion protection method, combined with the perfect shape of the tank, the practical maintenance port and the technologically advanced selective collectors make Calpak solar water heater (such as the innovative Mark 4 & VacuumTS) far more durable and economical than any competitive product made of stainless steel or steel coated with epoxy resins. In terms of construction composition, particular materials provide the tank with the appropriate thermal insulation and thus the solar water heaters hold hot water throughout the night. The success of the Calpak aluminum tank has been so great that a remarkable number of them are currently installed, supplying many households with hot water.

The basic parts of a solar water heater are the tank and the solar collector.

The performance of the system depends mainly on the collector technology that produces thermal energy. The quality of the tank, where hot water is temporarily storaged, is also important for the lifespan of the system and for hot water retention throughout the night.

Integrated central heating systems

 

 Climatism’s integrated central heating systems are manufactured under the most stringent efficiency standards. Calpak produces its own floor standing hot water tanks and is thus able to guarantee all the components required for an integrated central system. A typical Calpak system includes U-pipe tubes, an enameled hot water tank with dual heat exchanger, a solar station with automatic control system, expansion tank, supports for inclined roof, a special thermal fluid and a complete set of connecting elements (screws, etc.).

It should be noted that Calpak is the only Greek company —and one out of four in Europe— to produce vacuum tubes with the U-pipe method. In terms of size and type of vacuum tube collectors, they are selected based on customer requirements. By building its own water tanks, Calpak is able to guarantee that its solar water heaters will be corrosion-resistant.  Our wide range of systems covers up to 90% of the demand for hot water.

Vacuum TS series specifications

Absorber technology: The absorber is the most important part of the collector and its technology is directly related to the good performance of the system and therefore to energy saving: Copper hydroskeleton of U-pipe tubes (Φ8 copper tubes by HALCOR) with ultrasonic-welded copper fins, selective vacuum tubes and CPC parabolic reflector (ALANOD).
