Double‑jacket domestic hot water heat exchanger KOSPEL WP-100 (two‑shell C.W.U.)

The KOSPEL Double‑jacket domestic hot water heat exchanger WP-100 is engineered for indirect production of domestic hot water (DHW) using a primary heating circuit. Its double-shell construction provides concentric separation between the heating medium and potable water, enabling efficient heat transfer while protecting both circuits from direct contact and reducing corrosion risk. The device is intended for integration with boilers, heat pumps, or other central heat sources where a compact, indirect DHW solution is required.

Advantages

The double‑jacket design ensures stable and even heat exchange across the entire surface area, improving thermal efficiency in indirect DHW applications. Concentric shells provide reliable hydraulic separation between the primary heating circuit and domestic water, which simplifies system maintenance and reduces contamination risk. The unit's compact footprint and straightforward connection layout facilitate installation in existing central heating setups. Materials and construction are chosen to deliver corrosion resistance and long operational life under typical domestic conditions.

Suitable for

• Integration with gas, oil or electric boilers for indirect domestic hot water production
• Use with heat pumps and central heating systems requiring potable water separation
• Retrofit projects where a compact indirect DHW heat exchanger is needed
• Systems aiming to protect potable water from contamination by the primary heating circuit

Key specifications

• Type: double‑jacket (two concentric shells) indirect heat exchanger for domestic hot water
• Application: domestic hot water (DHW) production via primary heating circuit
• Installation: inline connection to primary circuit and potable water circuit; suitable for closed heating systems
• Construction: concentric shell design for hydraulic separation and indirect heat transfer
• Performance features: uniform heat distribution across exchanger surface; designed for corrosion resistance in potable water systems

How to use

Install the WP-100 heat exchanger in accordance with local plumbing and heating regulations, connecting the primary heating circuit to the outer or inner jacket as specified by the system design and connecting the potable water supply to the remaining jacket. Ensure proper orientation and secure connections to avoid leaks. Commissioning should include flushing both circuits, pressure testing, and controlled heating to confirm correct flow direction and temperature rise. Regular inspection of connections and periodic water quality checks will help maintain performance.

Usage recommendations

Use appropriate safety valves, air vents and temperature/pressure monitoring in the primary and potable circuits. Follow manufacturer or installer guidance for water treatment and corrosion prevention compatible with potable systems. For optimal performance, size the heat exchanger and set primary circuit flow rates to achieve the required DHW temperature and recovery time without exceeding maximum operating conditions for the connected heating source.
