Manifold Repairs & MaintenanceLondon & Surrounding Areas

Professional manifold servicing, repairs and replacements for all underfloor heating systems. Restore proper flow and heating balance to your system.

What is an Underfloor Heating Manifold?

The manifold is the central hub of your wet underfloor heating system. It distributes hot water from your boiler to each heating zone and collects the cooled water for reheating. A faulty manifold can cause uneven heating, cold spots, or complete system failure.

Flow Manifold

Distributes hot water from the boiler to each underfloor heating circuit. Features flow meters and isolation valves for each zone.

Return Manifold

Collects cooled water from each circuit and returns it to the boiler. Contains actuators controlled by room thermostats.

Common Manifold Problems

Leaking Connections

Water leaks from pipe connections, valves or the manifold body

Poor Flow Balance

Uneven heating due to incorrect flow rates between zones

Stuck Valves

Isolation or balancing valves seized due to limescale or corrosion

Air Locks

Trapped air in the manifold preventing proper water circulation
