Key benefits Precise zone control: Integrated flow meter lets you read and set water flow from 0–5 L/min so each heating circuit receives the correct flow for even room temperatures. Reliable, longlasting build: Brass body with ABS components resists corrosion and wear for dependable operation in residential or commercial radiant heating systems. Easy maintenance: Detachable sight glass provides fast access for cleaning and removes sediment blockages without disassembling the manifold. Improved comfort and efficiency: By regulating and balancing flow across manifold circuits, the device reduces cold spots and helps the system run more efficiently. What it does Acts as a flow meter regulator for underfloor heating manifold systems, providing visible, accurate flow readings and simple flow adjustment to balance multiple zones. Key specifications Compatibility: Designed for underfloor heating manifold systems with G1/2 and G3/8 connections. Flow range: 0–5 L/min displayed on the integrated flow indicator. Materials: Brass body and ABS components for durability and corrosion resistance. Design feature: Removable sight glass for inspection and cleaning to prevent sediment buildup. Why customers need it Ensures balanced heat distribution across rooms by enabling precise flow adjustment on each manifold circuit. Reduces maintenance time and risk of flow restrictions thanks to the removable sight glass. Fits standard manifold connections (G1/2 and G3/8) so it integrates with common underfloor heating installations. Typical applications Multiroom residential underfloor heating: Balance flow to living areas, bedrooms, and bathrooms to eliminate uneven temperatures. Small commercial spaces: Use on office or retail radiant systems to maintain consistent comfort across zones. Retrofit or maintenance work: worn or inaccurate meters on existing manifolds for improved performance and easier cleaning. Installation and maintenance notes Connect to manifold ports using the G1/2 and G3/8 fittings; designed to work in common radiant heating manifolds. Remove the sight glass for periodic cleaning if sediment appears; this preserves steady flow readings and system efficiency. Visual flow indication simplifies balancing during commissioning and routine checks.
