Manifolds & Actuators
What is an underfloor heating manifold?
Manifolds for underfloor heating are used to control the flow of water through the system. It distributes even warmth across the whole floor. They are central to your UFH system, connecting both the supply and return lines. Each manifold consists of a flow and return manifold – each with a flow meter to measure the flow rate. There is a valve on each loop that open and closes – controlled by the actuator valve in turn controlled by your smart room thermostat.
What is included with our Underfloor Heating Manifolds?
- Our manifolds range between 2 to 12 ports and come complete with isolating ball valves, adjustable flow meters, fill and drain points, automatic air vents
- Our stainless steel manifolds are pre-assembled for immediate mounting for both radiator and underfloor systems
- Available in 1” and 1¼” sizes, from 2 ways to 12 ways with integral flow control valves to suit a wide range of system requirements.
- Can be surface mounted , concealed in a choice of purpose designed plastic or metal cabinets or within a partition wall for a flexible solution to location.
- Manifold flow and return outlets are offset for space saving and ease of installation.
- Ball valves (with optional gauges), fittings and pipe connectors for a wide range of pipe types and sizes.
What is an actuator?
An Underfloor Heating 230V actuator (thermal electric actuator) is a vital and necessary element of your underfloor heating system. The actuator opens and closes the valve on the underfloor manifold according to the signal sent by your wet underfloor heating thermostat. Normally they are wired to an underfloor heating wiring centre.
Underfloor heating manifold dimensions
Below are the dimensions of our underfloor heating manifold and control pack. The installer should allow for the following recommended clearances when mounting the manifold on the wall: 200 mm between the finished floor level and the bottom of the manifold. 100 mm above the manifold. 50 mm on either side of the manifold.
Layout 1 is the standard setup for a manifold. Ball valves are placed between the manifold and the pump. This allows servicing or maintenance without draining the entire system.
| Port | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| A | 189 | 239 | 289 | 339 | 389 | 439 | 489 | 539 | 589 | 639 | 689 |

| C | 465 | 515 | 565 | 615 | 665 | 715 | 765 | 815 | 865 | 915 | 965 |
A – Width of manifold including fill & drain ports
B – Width of manifold & ball valves
C – Width of manifold, ball valves & pump
Layout 2 is preferred when horizontal space is limited. Installing the ball valves below the pump allows the length to be decreased. Shut-off valves are still included in the system.

VPS UFH CustomerGreat Underfloor Heating Manifolds - Great customer service, prices and delivery is absolutely brilliant
Very reasonable price, and superfast delivery
In the past I used to buy my underfloor heatings from different big names until VPS come across recommended by a friend. Long story short extremely happy with service, advice and sales cost provided by there staff.I will always recommend them to my clients.
