Heat block boiler module - unmixed

Unmixed heat block boiler modules are designed for direct integration into heating systems without mixing. These modules provide a compact solution for connecting boilers to heating circuits, incorporating essential components such as circulation pumps, isolation valves, temperature sensors, check valves, and thermal insulation. They are commonly used in residential and commercial heating systems where a direct flow of heated water is required without temperature blending.

Typical applications include central heating systems with radiators or underfloor heating, where the boiler output is directly fed into the distribution system. These modules are compatible with a range of boiler types and can be integrated into both new installations and system upgrades.

How to choose

• Select the nominal diameter (DN 25 or DN 32) based on the required flow rate and system size.
• Ensure compatibility with internal thread sizes (1" F for DN 25, 5/4" F for DN 32) for secure and leak-free connections.
• Consider the maximum output power (up to 46 kW for DN 25, up to 65 kW for DN 32) to match the heating demand of the system.
• Verify the nominal flow rate (Kvs 6 for DN 25) to ensure adequate circulation for the system layout.
• Confirm the material (brass) and insulation (EPP) meet the durability and thermal efficiency requirements of the installation.
