## Long description

KOSPEL SWPNL300 enameled water heater is a 300-litre storage boiler with an integrated 3.3 m heat exchanger designed for domestic and light commercial hot water supply. The unit features a corrosion-resistant enamel lining and layered storage design to improve temperature stratification and ensure a steady supply of domestic hot water. External connections for solar collectors, boilers or heat pumps enable combined system operation and seasonal setups.
Advantages
The enamel lining provides long-term protection against corrosion while maintaining water quality. The built-in 3.3 m heat exchanger delivers efficient heat transfer from solar, boiler or heat-pump circuits without mixing primary and domestic water. Layered storage improves energy efficiency by maintaining distinct temperature zones, which reduces standby losses and optimises heat source operation. The robust construction and standard connection set make it suitable for a variety of installations.
Suitable for
Domestic hot water supply for single-family homes and multi-apartment dwellings
Light commercial hot water needs such as guesthouses, small offices or workshops
Integration with solar thermal systems for seasonal or year-round use
Combined systems with boilers or heat pumps to provide DHW and buffer storage
Key specifications
Storage capacity: 300 litres
Integrated heat exchanger length: 3.3 metres
Internal protection: enamel lining for corrosion resistance
Design type: stratified (layered) storage for improved temperature separation
Application: domestic and light commercial domestic hot water (DHW) and combined systems
Connections: provision for external primary circuit (solar, boiler, heat pump)
How to use
Install the water heater according to local regulations and manufacturer installation guidelines, ensuring stable support and correct hydraulic connections for the primary heat source and domestic hot water circuits. Connect the integrated heat exchanger to the external primary circuit (solar, boiler or heat pump) using suitable piping and ensure proper fill, purge and pressure settings before commissioning. Set thermostat controls and safety devices as required, check for leaks and verify correct temperature stratification during initial operation.
Usage recommendations
For optimal performance, match the heat source capacity to the storage volume and ensure regular inspection of anode or enamel condition where applicable. When used with solar thermal systems, incorporate appropriate control and antifreeze protection for the primary loop. Periodic maintenance and descaling in hard-water areas will help maintain heat transfer efficiency and prolong service life.
