On delivery of the Econna-12 panels ensure that they are stored in a dry weather tight area, away from chemicals and that they are stacked horizontally and raised off the ground. The panels must not be exposed to moisture or high humidity.
The moisture content of the Econna-12 panels and plywood layer should be no higher than 10 % and they should ideally acclimatised together before installation.
Perform a site inspection. You will need to confirm that all measurements and other requirements on site match your working drawings. Ensure that all areas are correctly prepared, dry and protected from weather.
i Inspect the site for possible hazards that could damage the Warmup pipe, such as nails, staples, materials or tools.
i Ensure that insulation is installed between the joist in line with building regulations. Joists must be level and even, clear of debris and without any surface deviations such as knots or nails.
Dust particles may become airborne when cutting wood or insulation products. Therefore please follow relevant health and safety rules when cutting the panels or insulation by using a mask, goggles, gloves and ensuring adequate ventilation.
Econna-12 panels are a structural floor deck therefore extra pipe channels must not be routed into the panels as this would weaken the system.
i Ensure the end of each Econna-12 panel falls on a centre line of a joist. The shortest length of panel should be supported across a minimum of three joists. If a shorter panel is required it must be supported by noggins. Ensure that each row of panels has a group of return loops at each end.
Use a pipe cutter designed for plastic pipe ensuring that there are no burrs on the pipe ends. It is important to achieve a clean cut.
Do not pull pipe from the coil while it is sitting flat. It must be unwound from the coil, rotating the coil as the pipe is pulled from the inside.
Do not force the pipe into bends. It is easier to lay the pipe with a large radius and then gently pull the pipe to the required bend. The minimum bending radius is 5 times the diameter of the pipe.
Do not kink the pipe. Excessive bending of the pipe can cause it to kink, where this occurs flow may be obstructed or reduced. Kinked pipe must be repaired or replaced. To repair a kink, straighten the pipe and simply heat the area with a hot air gun until the kink disappears.
Before installing the floor finish, its suitability for use with underfloor heating and its maximum operating temperature should be checked against required operating conditions.
i Underfloor heating performs the most efficiently with conductive, low resistance floor finishes such as stone and tiles. Consideration should be given to the thermal resistance and temperature limits of the chosen floor covering and its impact on the system heat output.
| All floor finishes | |
| 1 | Floor finish |
| 2 | 6 mm minimum plywood deck This layer must be screwed to the Econna-12 panels to complete the structural deck |
| 3 | Warmup 12 mm PE-RT pipe |
| 4 | Floor sensor Must be recessed into the Econna-12 panel and taped in position. |
| 5 | Econna-12 panels Panels secured together using a D4 adhesive on BOTH sides of the tongue and groove and fit together. Panels then glued and screwed to the joists. |
| 6 | Joists ≤ 600 mm centres Refer to tiling standards for maximum joist centres for floors to receive tiles |
| 7 | Insulation layer Thickness in line with building regulations |
| 8 | Flow and return pipes* Installed beneath the Econna-12 panels, notched or through holes drilled in the joists in line with building regulations. |
| * Service pipes must be insulated within the joist space and supported at 300 mm intervals on horizontal runs and 500 mm on vertical runs using pipe clips | |
To prevent excessive heat loss through the floor, ensure that insulation is installed between the joist in line with building regulations.
If using temperature sensitive materials above Econna-12, such as damp proofing or tanking systems, contact the manufacturer for advice.
Where ceramic tiles are to be used, ensure that the subfloor meets the local tiling standard requirements.
Do not commence installation of the Econna-12 panels without ensuring that the resulting floor construction will meet the requirements of the floors intended use and its finish.
Joist notching/drilling
Joists must be level and even, clear of debris and without any surface deviations such as knots of nails before laying the Econna-12 panels
Joists will have to be drilled or notched in line with building regulations to allow for the flow and return pipes to enter the room. Ensure the notches or holes are large enough to allow for the expansion and contraction of the pipes. All exposed pipework within the joist spaces must be insulated.
Joist notching
Joist drilling
The images above are for guidance only, please refer to building regulations for full information on how to notch/drill into joists.

If a shorter panel is required it must be supported by noggins.
- Feed the pipe through the hole through to the manifold location, notching/drilling the joists as required in line with building regulations.

If the project has been supplied with a set of working drawings, follow the provided pipe layout. Ensure each circuits details are recorded in the commissioning log provided in the Warmup manifolds installation manual.
- Plan the circuit layout ensuring that the flow and return pipes can connect from the manifold to their respective heated area without crossing each other.

All exposed pipework within the joist spaces must be insulated with lagging.
Underfloor heating pipe within the joist space should be supported at 300 mm intervals on horizontal runs and 500 mm on vertical runs when fixing the pipe to vertical surfaces. Pipes should be secured to the joists using clips.
Use pipe bend supports on route to the manifold location.
A minimum 6 mm flooring grade plywood covering must be installed in the opposite direction to the Econna-12 panels. This layer must be screwed into the Econna-12 panels to complete the structural deck.

Interior view of a room with two wooden flooring panels, one showing green material and the other showing white tiles (no text or symbols visible)- Lay a 6 mm flooring grade plywood in the opposite direction to the Econna-12 panels. The plywood covering should be positioned so that each plywood panel overlaps the tongue and groove edges of the Econna-12 panels by 300 mm.
- Screw the plywood covering into the Econna-12 panels using 25 mm wood screws, 18 mm in from the edge of each plywood sheet and then at 150 x 150 mm centres, ideally in the centre line between the pipe runs.
It is best practice to predetermine and mark the pipe and screw positions on the top surface of the ply layer to avoid the straights and loop ends of the pipe runs.

| ISSUE 2 - Cracked tiles | |
| PROBLEM SOLUTION | |
| There is excessive movement of the joists or the joist spacing is larger than recommended by building regulations causing the floor to flex leading to cracked tiles. | The issue with the subfloor has to be resolved otherwise the tiles will continue to crack |

Using the system k_H value to calculate the system heat output:
$$ \mathbf {q} = \mathbf {k} _ {\mathrm{H}} \times \left(\mathbf {T} _ {\text { water }} - \mathbf {T} _ {\text { air }}\right) $$
Example:
The heat output through an 18 mm thick, ≈ 1.25 tog timber floor, over Econna-12 with 6 mm ply, fitted with pipe at 150 mm centres, in a 21°C room heated with 40°C water is;
$$ q = 2. 3 0 \times (4 0 - 2 1) = 2. 3 0 \times 1 9 = 4 3. 7 \mathrm{W} / \mathrm{m} ^ {2} $$
Alternatively, using the system k_H value to calculate the required water temperature, knowing the required heat output:
$$ T _ {\text { water }} = (q / k _ {H}) + T _ {\text { air }} $$
Example:
The water temperature required to produce a heat output of 55W/m ^2 , through a 3 mm thick ≈ 0.25 tog LVT floor finish, over Econna-12 panels with 6 mm ply, fitted with pipe at 150 mm centres, in a 22°C room is;
$$ T _ {\text { water }} = (5 5 / 3. 1 1) + 2 2 = 1 8. 5 + 2 2 \approx 4 0. 5 ^ {\circ} \mathrm{C} $$

Using the graph above it is possible to limit the specific heat output to the required value.
The example above shows a design room air temperature of 20^ C and an design heat output of 52.5 W/m^2 . Based on a 0.150 m^2 K/W (1.5 tog) floor finish the floor sensor should be set to 33^ C ( 20^ C room air + 13^ C T ) to resulting in floor surface temperature of 25^ C ( 20^ C room air + 5^ C T ).

The design floor surface temperature difference should not be more than 9 °C in occupied areas, 15 °C in unoccupied areas.
Heat output is limited by the floor finish resistance combined with the maximum probe setting of 40 °C.
Temperature limits of the floor finish or its adhesive may adversely limit the design heat output.
