Stainless Steel
The material is SUS304 stainless steel, placing it in the category of highly suitable and quality tanks for domestic hot water preparation. Insulation is polyurethane sponge 50mm thick. All tanks feature a coil (corrugated, wavy stainless steel pipe) with a surface of 2.26 m² across all volumes, making them suitable for connection with heat pumps. The dual-coil variant has a total surface of 4.52 m² — one coil for the heat pump, the other for solar systems or an additional energy source. Maximum working pressure is 6 bar, maximum working temperature is 90°C.
