The Altek SD-P-20 heliosystem is built as a tank-in-tank design. The inner tank is made of stainless steel SUS316L. A thermosiphon non-pressurized seasonal water heater is assembled from individual vacuum tubes. Solar radiation energy is absorbed by the absorber and converted into heat to warm the water, and thanks to an effective selective coating the efficiency of the solar collector is increased. This system operates with free circulation of the heat-transfer fluid. A vacuum tube structurally consists of two glass envelopes, air being evacuated from the space between them, which reduces heat loss.

The design and coating of the tank provide resistance to corrosion and good thermal insulation.
