Boiler assembly - unmixed, with bypass valve

Boiler assemblies in this category are designed for integration into heating systems where non-mixed operation is required. These units typically include a horizontal distribution manifold, supply and return piping, a circulation pump, overflow valve, and insulation. They are suitable for residential and commercial heating applications, especially in systems where precise temperature control and flow management are essential.

Each assembly is pre-fitted with components such as ball caps, manual venting valves, non-return valves, and thermometers. The materials used include brass (CW617N, CB753S) and polystyrene (PS) insulation, ensuring durability and thermal efficiency. The standard connection is internal-external 5/4" F × 5/4" M, compatible with common pipe systems.

How to choose

• Confirm the maximum flow rate (up to 3000 l/h) matches the system's demand.
• Verify the connection thread type (5/4" F × 5/4" M) is compatible with the existing piping.
• Check the operating temperature limit (+120 °C) and pressure rating (PN 10) for system compatibility.
• Ensure the inclusion of necessary components such as thermometers, non-return valves, and manual venting valves for your specific installation.
