YI.A Anti-Scaling Brass Underfloor Heating Manifold

The MENRED YI.A manifold distributes supply water to underfloor heating circuits and collects the return flow. Built-in supply-side balancing valves allow manual circuit adjustment, while return-side shut-off valves can operate with compatible thermal actuators controlled by room thermostats.

The series includes 2–8 circuit models. Its anti-scaling valve actuation design is intended to reduce valve sticking associated with scale buildup. Appropriate system water quality management and maintenance remain important.

Key Features

  • Forged brass body with surface corrosion protection.
  • Anti-scaling valve actuation design intended to reduce sticking.
  • Manual balancing valves and return-side shut-off valves.
  • Axial static seal design.
  • DN25 main manifold with 50 mm outlet spacing.
  • Separate pipe connectors selected according to pipe dimensions.
  • Clip-on wall-mounting brackets.

Widths are based on the configurations in the YI.A datasheet. Confirm the complete assembly dimensions and allow space for the selected valves, fittings, actuators and pipe connections before installation.

Components and Ordering

The datasheet illustration identifies thermal actuators, an H106-Yi automatic air vent, an H105-Yi three-port end fitting, an H107 drain valve and an H25-P pressure gauge. Confirm which components are included in the quoted configuration.

Straight and angled ball valves are optional and ordered separately. Select pipe connectors according to the heating pipe dimensions.

Selection and Installation

Select the circuit count according to the heating system design. Check pipe connector dimensions, actuator compatibility and installation space before ordering. A matching mounting thread alone does not establish actuator compatibility; valve geometry and operating travel must also be checked.

Compare the YI.N brass manifold or explore MENRED’s manifolds and wiring centers for related options. Installation, pressure testing and circuit balancing should be carried out by a qualified heating professional.

Frequently Asked Questions

What is the difference between YI.A and YI.N?

Both series use brass manifolds with manual balancing valves. YI.A additionally specifies an anti-scaling valve actuation design intended to reduce valve sticking.

Does the anti-scaling design eliminate maintenance?

No. It does not replace appropriate system water quality management, inspection or maintenance.

How many circuits are available?

The YI.A series includes 2–8 circuit models, from YI.A2 to YI.A8.

Are the illustrated accessories included?

Confirm the complete supply configuration in the quotation. Straight and angled ball valves are optional and ordered separately.
