Mixergy Heat Pump Kit - Plate Loading Kit for Cylinder

The Mixergy Heat Pump Kit (KIT-HEATPUMP-02) is a complete plate loading conversion kit that transforms any existing Mixergy cylinder into a fully functional heat pump cylinder for efficient low-temperature heating applications.

Product Description

This plug-and-play kit enables seamless integration of Mixergy cylinders with air source heat pumps using primary plate heat exchange technology. Designed for UK retrofit projects, it maintains the smart cylinder's stratification benefits while accepting low-temperature heat pump flow (35-55°C).

Key Features

• Universal compatibility: Converts any Mixergy cylinder (150-300L) for heat pump operation.
• Primary plate exchange: Separates heat pump primary circuit from cylinder secondary water.

• Lowara Ecocirc variable speed circulation pump included.
• Smart controls: Heat pump interface board with temperature sensors and flow management.
• Complete kit: All pipework, fittings, sensors, and hydraulic schematics provided.
• F Gas compliant: No refrigerant handling required for installation.

Kit Contents

• Stainless steel plate heat exchanger (primary side heat pump compatible)
• Lowara Ecocirc circulation pump (variable speed, high efficiency)
• 4x PT1000 temperature sensors (flow, return, cylinder top/bottom)
• Pre-assembled pipework kit with isolation valves
• Heat pump interface control board
• Comprehensive hydraulic schematic drawings
• Mounting brackets and fixings

Technical Details
