## Summary description

KOSPEL SB-501 L is a vertical heat exchanger equipped with two internal coils for indirect heating and heat transfer applications. Designed to connect to external heat sources, it separates primary and secondary circuits to ensure efficient energy transfer and sanitary water heating. Typical uses include integration with boilers, solar systems or heat pumps for domestic hot water or buffer storage.

## Long description

KOSPEL SB-501 L with 2 coils (vertical) is a stainless-steel buffer and indirect water heater designed for separation of primary and secondary circuits. The cylinder includes two internal heat-exchange coils that allow simultaneous connection of two heat sources or staged heat transfer from one source to multiple consumer circuits. The vertical layout and internal coil arrangement make this heat exchanger suitable for domestic hot water systems, buffer storage and integration with boilers, solar thermal collectors or heat pumps.
Advantages
The dual-coil configuration permits independent connection of two heat sources, increasing installation flexibility and enabling prioritized or parallel heat supply. The vertical design reduces footprint and facilitates natural stratification for improved thermal layering. Constructed from corrosion-resistant materials and designed for indirect heating, the unit provides hygienic separation between heating medium and potable water. The internal coil geometry ensures efficient energy transfer and supports integration with various external systems.
Suitable for
 Domestic hot water production in residential buildings
 Buffer storage for heating systems and heat pumps
 Integration with solar thermal systems
 Combined systems where two separate heat sources are used (e.g., boiler + solar)
 Systems requiring sanitary separation of primary and secondary circuits
Key specifications
 Configuration: vertical cylinder with two internal heat-exchange coils
 Function: indirect heating / heat exchange between primary and secondary circuits
 Material: corrosion-resistant construction suitable for potable water applications
 Coil arrangement: two separate coils to allow connection of two heat sources or circuits
 Application: domestic hot water, buffer storage, solar thermal and heat pump integration
How to use
Connect the primary heat source(s) to the designated coil inlets and the secondary circuit to the tank outlets according to the installer’s piping layout. Commission the system following the manufacturer’s instructions and local regulations, including flushing, filling and ventilating the circuits and verifying correct flow directions. Use appropriate safety devices, pressure relief valves and expansion vessels on the primary and secondary sides as required by the installation. Maintain recommended operating temperatures and perform regular checks for leaks, insulation integrity and correct pump operation.
Usage recommendations
For reliable performance, match the coil heat-exchange capacity with the connected heat sources and maintain correct flow rates through each coil. Ensure routine maintenance of external heat sources and check connections for scaling or sediment if using hard water. When integrating solar collectors or a heat pump, include appropriate controllers and sensors to optimize charging of the buffer and prevent short-cycling.
