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 5 & Prisma) 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.
Mark 5
A solar water heater must deliver high performance to fully meet your hot water needs.
The Mark5 features the most powerful collector in Europe, based on certified measurements (80% efficiency and minimal heat losses), along with an optimally designed heat exchanger that ensures efficient transfer of energy from the collector to the tank.
Power
A solar water heater should be highly efficient to reliably cover your daily hot water demands. The Mark5 stands out with the strongest collector in Europe, according to certified data (80% efficiency and very low thermal losses), as well as a carefully engineered heat exchanger that maximizes energy transfer to the storage tank.
Robustness
A solar water heater must be durable so you can benefit from free solar energy for many years. The Mark5 is built using top-quality materials and in accordance with strict manufacturing standards. It features a DC-03 steel tank (DIN 10130), robotic pulse TIG welding, enamel coating according to DIN 4753/3, a collector with double-wall aluminum profile (2.4 mm) and aluminum back sheet, as well as a fully aluminum support base.
Design
A solar water heater should also be well-designed to match your aesthetic preferences. The Mark5 follows modern design principles focused on minimalism and ergonomics, and has been awarded the internationally recognized Red Dot Design Award.
