Wilo Pump With Underfloor Heating Manifold And Pump Pack & Valves – Wilo A Rated Pump – 2 to 12 Ports
What’s included in our pump and manifold packs?
Items included:
- 1 x “A” Rated Wilo Pump
- 1 x pre-mounted manifold with flow meters
- 1 x end vent
- 1 x pressure gauge
- 2 x ball valves
- 2 x temp gauge (fitted to ball valves)
- Pipe Connectors (Eurocones)
- Pump station (blending valve)
- Supplied on a pre-mounted bracket.
Features & Benefits:
- Wilo A-rated pump has a thermostatic valve to control the flow temperature of water to the underfloor heating pipes.
- Temperature range: 35C – 65C
- Working pressure: 3 bar max test pressure 10 bar.
- Our manifolds are for use on water underfloor heating systems. These consist of two manifold bars, one for the flow and one for the return, complete with ball valves, drain/ filling valves and air vent. On the flow bar, each port has a high-performance flow indicator, with isolator including an easy-to-read gauge-glass.
- Each port on the return bar is equipped with an integral control valve and protection cap which allows the user to adjust the volume of water or can be removed to accept a Manifold Thermoelectric head (actuator).
Underfloor Heating:
The Underfloor Heating Site is one of the UK’s leading underfloor heating suppliers backed by indsutry leading suppliers with years of knowledge in the Underfloor Heating Industry. We are dedicated to supplying the best quality underfloor heating products at affordable prices & this is supported by first-class customer service & advice. Whether you are just tiling a small bathroom or looking for a full home heating system, we are confident that we have the right system for you.
Our Range includes water underfloor heating kits or just the underfloor heating manifold, underfloor heating pipe, heated floor mat, free cable, insulation, mirror demister pads, plus many products.
Where to Start with Underfloor Heating:
There are now dozens of web-based businesses selling underfloor heating, some are well established & some are new to underfloor heating & have little experience. So how do you sort the wood from the trees? Our advice is to do some basic research on the company; do they give you an address & a number you can contact if something goes wrong?
Designed for DIY Installation:
Our systems are designed for the DIY’er (connections must be made by an electrician), so if you know which type of underfloor heating you are looking for, please browse the relevant section of our shop. You can place your order online and we aim to deliver all stocked items next working day.
Let us do the work for you, email us with details of your underfloor heating project & we will be happy to explain your options. There is absolutely no obligation and we are happy to confirm all quotes in writing.

Installation Notes
Installation for a Multiple Room
- Select a suitable location for the pump and manifold unit and mount on the wall. See next page for assembly.
- Refer to the typical pipe installation drawings and determine the pipe layout – the layout is not critical and can be varied to suit site conditions, the important criteria being the pipe spacing, see below
- The pipe is marked every metre by the metre. (maximum length for any circuit Is 100m.70m for low profile 12mm pipe circuit).
- Pipes should be laid l 00mm away from walls
- Do not lay pipe under fixed units.
- Lay the rooms furthest from the manifold and work back, do the room with the manifold last.
- hen pipes to/from one area pass through another area, the two pipes should be run together, the ‘bunches’ of pipes should then be spaced as if they were one pipe.
- Lay the pipe as planned, fixing every 50cm if on a screeded celotex base and return to the manifold.
- If the pipe is kinked when bending. the pipe should be straightened and rearranged so that the location of the kink remains in a straight length, no other remedial action is required.
FILLING THE MANIFOLD SYSTEM (cont.)
- IMPORTANT that the underfloor heating system is properly filled with water and purged completely of air to ensure correct operation, it is therefore necessary to follow the procedure below.
- IT IS NOT ADEQUATE TO FILL THE SYSTEM USING THE BOILER FILLING LOOP!
- Connect a hose from a mains pressure cold water supply to the hose connection on the top (flow) manifold, and another hose from the hose connection on the bottom (return) manifold to a drain.
- Ensure that all the white caps on the bottom (return) manifold are screwed down, closing the valves.
- Ensure that the main flow & return ball valves are closed on the manifold.
- Turn on the water and open the hose connection valve on the top (flow) manifold.
7 Open the first circuit valve by unscrewing the white cap allowing water to flow into the pipe.
- Open the hose connection valve on the bottom (return manifold) allowing water to flow freely into the drain until the water is clear with no air bubbles.
- Open the second circuit valve (white cap) and close the first.
1o. Open the third circuit valve and close the second etc.
- Continue until the last circuit has been purged and close the hose connection valve on the bottom (return) manifold before closing the last circuit valve (white cap).
- While under pressure, check manifold & pipework for leakage.
- Close hose connection valve on the top (flow manifold) and remove the hoses.
Commissioning & Maintenance Notes
COMMISSIONING
- Screed or chipboard flooring should be laid immediately after pipelaying to protect the pipe.
- Concrete screed floors must be cured before any heat is applied, a general rule of thumb is to allow 7 days per 2 millimetres of the screed.
- Timber floor with drymix infill can have heat applied immediately, the drymix must be dried completely before laying the flooring.
- Hardwood timber flooring must be ‘conditioned’ before fixing.
- It is important to purge the pipework from the boiler to the manifold, to avoid air being introduced into the underfloor heating system.
- It is not normally necessary to balance the system but if required follow this procedure. The system is balanced by running the pump and adjusting the flow to each zone by turning the square spigot s under the white caps on the bottom manifold, the flow in the respective sight glasses should be set at a figure calculated by dividing the length of pipe for that zone by 40. Example: Circuit 1, 85m/40= approx2 on the scale. Low profile systems circuit at 70m;-40=1.75.
- Fit actuators to valves after connecting the control wiring.
- It is important that the actuators are screwed tightly on to the valve.
- Initially start the system with the thermo static valve set at min (35°c).
- Increase the setting by 5°c per day, up to a maximum of 50° for concrete floors, max 65° for timber floors.
- The flow & return from the boiler should be connected to the manifold connections shown using compression couplings.
- NOTE. When first starting up the system it may take 12-24 hours for the heating effect.
MAINTENANCE We recommend that the following maintenance be carried out annually.
- Check that all actuator nuts are tightened firmly and that actuators are not loose.
- Remove end plug from pump and check that pump rotates when energised.
- Turn up thermostats & check that actuators move into open position also check flow gauges are indicating. If not, re-pressurise manifold, remove indicator, clean & replace, repressurise manifold.
