Indirect Domestic Hot Water Heat Exchanger SWK-100.A.PL, 100 L, top connections, white

The indirect domestic hot water heat exchanger SWK-100.A.PL with 100 L capacity is designed for preparation of sanitary hot water by transferring heat from a central heating source. The unit features top-mounted hydraulic connections and an internal heat transfer coil, and is finished in white to integrate visually with typical residential installations. Intended for connection to boilers, heat pumps or other central heating circuits, this exchanger provides a compact solution for single-family homes or small multi-family dwellings where indirect DHW preparation is required.

Advantages

The SWK-100.A.PL combines a 100‑litre storage volume with an internal coil that enables efficient heat transfer from a primary heating circuit without direct mixing of fluids. Top-mounted connections simplify piping runs in retrofit or replacement installations and can reduce installation time in confined plant rooms. The white exterior offers a neutral appearance suitable for domestic utility spaces. The design supports integration with common heat sources such as gas or oil boilers and electrically driven heat pumps.

Suitable for

• Residential hot water preparation in single-family homes
• Replacement of existing indirect DHW cylinders
• Integration with boilers, heat pumps or central heating circuits
• Small multi-family installations with moderate hot water demand

Key specifications

• Useful volume: 100 litres
• Connection type: top-mounted hydraulic connections for flow and return
• Heat transfer: internal coil for indirect heat exchange
• Finish: white exterior
• Application: indirect domestic hot water (DHW) preparation

How to use

Install the heat exchanger according to local plumbing and heating regulations, ensuring secure top connections to the primary heating circuit and to the domestic cold and hot water lines. Fill and vent the primary circuit and the domestic cylinder in line with the system commissioning procedure to remove air and confirm correct flow through the internal coil. Adjust boiler or heat pump settings to provide the required supply temperature and verify control and safety devices operate as intended before regular use.

Usage recommendations

For reliable operation, use corrosion-inhibited water in the primary circuit where recommended, and implement suitable water treatment for domestic water according to regional standards. Schedule periodic inspection of connections and anode (if present in the product variant) and consider professional commissioning to ensure compatibility with the chosen heat source and control system.
