When it comes to installing underfloor heating, FloFloor’s unique design keeps things simple and straightforward. The lightweight and manoeuvrable panels can be cut to size quickly and the 12mm pipe fixes easily within the pre-perforated channels. The panels are also universal and multi-directional, meaning no separate loops and straights need to be laid.

FloFloor also provides extremely strong support for the floor deck. At 300kPa, the panels prevent the floor from sagging over time and protect the system from being damaged during installation. Thermal boards for underfloor heating help to prevent downward energy losses. Meanwhile, the aluminium foil layer helps to distribute the heat evenly and give the system a high heat output. The foil also replaces the need for separate spreader plates, considerably speeding up the installation.

Furthermore, the perforated foil also displays the pipe channels to make it easy to see where to fit the pipe. This all combines to create a simple yet durable and energy efficient UFH system. Find more on How CircofloPro Works Here.

Step 1

Step 1

Make sure the floor is flat, clean, and clear of any debris. Ensure existing slab/floor deck meets at least SR2 (5mm deviation in 2m) requirements for floor regularity (BS8204) and preferably SR1 (3mm deviation in 2m).

Note: the floor finish company may have their own requirements which take precedent.

Timber Floors: LowDeck can float or be mechanically fixed. (undulations in the floor will transfer through the LowDeck).

Solid Floors: A thin layer of non-compressive insulation/insulative matting can be laid prior to fitting LowDeck to provide some resistance when layering over an insulated floor.

Step 2

Step 2

Attach the manifold to the wall using appropriate wall mounting fittings. You can arrange the flow and return pipework in a variety of ways, depending on what is best for your installation. The two manifold arms should be within 500mm of each other to allow for the actuators (with 1500mm of cable) to be connected into the 4-zone wiring centre positioned close by.

Step 3

Step 3

Lay panels in a ‘run’ in front of each other along the room, cutting to fit any corners. Cut the final panel in the run to fit and use it to start the next run. Make sure that the pipe channels on the offcut section line up with the neighbouring panels.

Note: Use un-piped FloFloor panels or plain insulation of the same thickness and grade to complete the insulation layer in unheated areas.

Step 4

Step 4

Starting at the manifold and working from the edge of the room, push the pipe into the pre-perforated foil channels in a serpentine pattern. Ensure there is enough pipe exposed from the floor to reach the ports on the manifold. Do not lay the pipe in any areas which will be unheated (such as underneath kitchen units).

Additional channels for flows and returns may be required where the pipes approach the manifold. To create extra channels, use a blade knife to score and peel back the foil where the channels will be located. Next, use a Circoflo hot blade cutter to create the new channels.

Note: If at any point the pipework is kinked, the coil must be replaced.

Step 5

Step 5

When returning the circuit to the manifold, cut the pipe with a pipe cutter ensuring that the pipe is long enough to reach the manifold. Label the pipe with flow and return, and number the circuit. This will help when connecting to the manifold.

Note: Once the panels and pipe have been laid, they should be protected with walking boards, especially in areas with high levels of foot traffic such as doorways.

Step 6

Step 6

Connect the 22mm primary pipework from the heat source. If you require a mixing unit this will need to be installed in the primary heating pipework along with a standard pump, typically located beside the boiler/ heat source.

Fit the Monoblocco connectors on to the ends of the 12mm pipe and screw onto the manifold by hand. Using a spanner, tighten the connection whilst maintaining upwards pressure on the pipe.

Note: Once connected, it is recommended to insulate all primary pipe work.

Before continuing, complete the connection checklist below:
• All manifold joints are tight and sealed
• Primary flow and return are connected to the manifold correctly
• Isolating valves and drains left closed
• Pipes marked with circuit numbers and “flow” or “return”
• Ensure that all FloFloor panels butt tightly together with no gaps, but a 10mm gap has been left around the edge of the room for expansion.

Step 7

Step 7

If your project uses more than one CircofloPro Underfloor Heating System, lay all of the other systems and connect to the manifold(s) before moving on to filling the systems. Now follow the commissioning and bleeding instructions on the manifold. Make sure to fill out the commissioning information in the manifold booklet.
