Underfloor Heating Manifold Installation
A correctly installed underfloor heating (UFH) manifold is what makes a wet UFH system run smoothly. It distributes warm water to each pipe circuit, controls flow rates, and helps deliver even room temperatures at low operating temperatures. This service covers the supply and fitting of the manifold assembly, pump and blending valve where required, plus proper testing and commissioning so the system performs as it should.
More information
What manifold installation includes
A UFH manifold is not just a set of pipes. It is the control point for comfort, efficiency, and reliability across every heating loop. Installation typically includes:
- Manifold selection and layout to match your number of zones and circuits.
- Mounting the manifold in a suitable location with access for future servicing.
- Connecting primary flow and return pipework from the heat source.
- Fitting a pump set and blending valve (where needed) to achieve safe UFH temperatures.
- Connecting UFH pipe circuits, with clear labelling for each loop.
- Pressure testing and leak checks before the system is put into use.
- Filling, flushing and commissioning to remove air and support stable circulation.
- Flow setting and initial balancing for even heat distribution.
- Handover advice on basic operation and what to watch for.
When this service is a good fit
Manifold installation is ideal if you are:
- Installing wet underfloor heating in a new build, extension, or renovation.
- Replacing a faulty, leaking, or poorly performing manifold.
- Adding zones or circuits and need a larger manifold or better control.
- Switching heat sources (for example, upgrading to lower temperature heating) and need correct blending and pumping.
- Managing a rental or small commercial space where dependable, consistent heating matters.
How the installation is delivered
Work usually follows a clear sequence:
- Confirm system requirements: number of loops, heat output, control approach and pipework routes.
- Fit and pipe in the manifold: secure mounting, isolation valves, and primary connections.
- Install pump and blending controls where required to protect the floor system from excessive temperatures.
- Connect, test and commission: pressure test, fill, purge air, and verify circulation.
- Balance the circuits: set flow rates and check for even heat delivery across zones.
The exact timing depends on site readiness and whether the manifold is part of a wider UFH install, but you will be kept informed on what is needed before and after the visit.
After installation: performance and peace of mind
Commissioning and balancing make a noticeable difference to comfort and running costs. After installation, you will have a system that is easier to control, simpler to service, and less likely to suffer from cold spots, noisy circulation, or uneven room temperatures. If issues show up later, the manifold provides a clear point for diagnostics and adjustment.
