Description
Power
A solar water heater must be very powerful to fully cover your hot water needs. The Mark5 has the most powerful collector in all of Europe, based on certified measurements (80% efficiency and minimal thermal losses), as well as the best designed heat exchanger that ensures the efficient transmission of energy from the collector to the tank.
Robustness
A solar water heater must be robust so that you can enjoy the free energy of the sun for many years. The Mark5 is made with the best materials and according to the strictest quality standards. It has a DC-03 steel tank according to DIN 10130, pulse tig robotic welding, enamelling according to DIN 4753/3, collector with 2.4 mm double-walled aluminum profile and aluminum back as well as an all-aluminum base.
Design
A solar water heater should be well designed to match your aesthetic. The Mark5 is designed according to the modern trends of abstraction & ergonomics and has been awarded with the internationally recognized reddot design award.
