Standing Heat Exchanger with Spiral Coil KOSPEL SW-100.TERMO-MAX
KOSPEL SW-100.TERMO-MAX is a standing heat exchanger with an internal spiral coil designed to transfer heat from a primary circuit to stored domestic hot water. The upright tank and spiral coil construction provide efficient indirect heating and hydraulic separation between primary and secondary circuits, allowing integration with boilers, heat pumps or solar thermal systems. The product is intended for domestic and light commercial installations where reliable indirect heating and straightforward maintenance are required.
The spiral coil design increases heat transfer surface area while maintaining compact tank dimensions, resulting in fast water heating and stable outlet temperatures. The standing configuration simplifies connection to existing piping layouts and provides accessible service points. Constructed with corrosion-resistant materials and standard connections, the exchanger supports long-term operation and routine maintenance without specialized adapters.
Install the unit in a frost-free technical room on a level surface, providing access to all connection points. Connect the primary circuit (boiler, heat pump or solar loop) to the coil inlet and outlet ports and connect the secondary circuit to the tank’s hot water inlet and outlet. Ensure correct orientation of flow directions and follow local plumbing codes and recommended pressure-limiting and safety devices. After filling and venting the system, gradually bring the primary heat source up to operating temperature and check for leaks and stable hot-water delivery.
Use appropriate corrosion protection and water treatment according to local water quality. Install safety valves, expansion vessels and temperature/pressure monitoring as required by regulations. Schedule periodic inspections to verify tightness of connections and condition of insulating surfaces to ensure long-term performance.
