Minishunt
Description
The Compact, Pre-Assembled Control Unit for Faster, Smarter Heating Installations
The Watts Mini Shunt is a compact, factory-assembled hydraulic control module designed to simplify installation and deliver stable, energy-efficient performance in small-zone heating applications. Engineered for reliability, it integrates all primary hydraulic components—including a Wilo® circulation pump, thermostatic mixing assembly, non-return valve, and a full EPP insulation shell—in one ready-to-install unit.
With its slim, wall-mounted design and universal connections, the Mini Shunt enables rapid installation, reduces configuration errors, and fits perfectly into renovation projects, mixed-temperature systems, and compact new-build environments.
Benefits
Fully Pre-Assembled for Fast, Error-Free Installation
All essential components are factory integrated to reduce labour time and eliminate assembly variability—ensuring consistent system performance across projects.
Compact Footprint for Tight Spaces
The slim design fits easily into cabinets, niches, and renovation spaces, making it ideal for bathrooms, towel rails, and single-room underfloor heating zones.
Built-In Wilo® Circulation Pump
A trusted and reliable pump ensures smooth commissioning, stable operation, and reduced risk of field failures.
Stable Temperature Control (20–70 °C)
The thermostatic mixing valve with sensor feedback provides immediate, consistent temperature—improving comfort and system safety.
Full EPP Insulation Shell
High-performance insulation minimises heat loss, supports energy-efficiency goals, and requires no additional site installation.
Universal G ¾” Eurocone Connections
Standard fittings allow fast, familiar installation with fewer leakage risks and no need for special adapters.
