## Long description

Galmet Wymiennik SGW(S) B SILIM 250L is a 250-litre indirect water heater designed for domestic hot water storage. The cylinder includes two spiral heat exchangers that allow connection to a boiler and a secondary heat source such as a solar thermal system. The tank is protected by polyurethane foam insulation to reduce standby heat losses and maintain stored water temperature for longer periods. The unit is intended for installation in residential or small commercial settings where reliable, continuous hot water supply is required.
Advantages
The dual spiral heat exchangers provide flexible hydraulic configuration: one exchanger can be dedicated to a primary heat source (for example a gas or solid fuel boiler) while the second exchanger connects to an auxiliary source like solar collectors or an external heat pump. Polyurethane foam insulation improves thermal retention and reduces cycling of the heat source, helping to maintain stable output temperatures. The 250-litre capacity supports simultaneous use at multiple draw-off points and helps balance supply during peak demand. Construction materials and coil arrangement are chosen for effective heat transfer and integration with standard plumbing systems.
Suitable for
 Residential hot water storage for single-family homes
 Integration with boilers and solar thermal systems
 Small commercial premises with moderate hot water demand
 Systems requiring simultaneous supply to several sanitary points
Key specifications
 Storage capacity: 250 litres
 Two spiral (coil) heat exchangers for independent circuits
 Thermal insulation: polyurethane foam
 Designed for indirect heating from boilers, solar thermal collectors, or external heat sources
 Suitable for wall or floor placement according to installation instructions
How to use
Install the water heater according to local regulations and the manufacturer’s installation manual, ensuring correct hydraulic connections for the primary and secondary heat exchangers. Connect the primary heat source to the designated coil and the auxiliary source (solar or heat pump) to the secondary coil if required. Commission the system by filling the tank, removing air from the coils and piping, and verifying that safety valves, temperature sensors and any control thermostats operate correctly. Adjust settings on the boiler or controller to achieve the desired domestic hot water temperature and to prioritize sources according to system design.
Usage recommendations
For efficient operation, insulate supply and return pipes, perform periodic maintenance such as inspection of sacrificial anode (if fitted), check for sediment accumulation and ensure proper operation of safety devices. When integrating with solar thermal systems, use appropriate controls to prevent reverse circulation and to optimize heat exchange between collectors and the tank.
