- Lay your chosen floor covering over the floating floor deck, in accordance with floor manufacturers instructions.

• Install your Warmup thermostat referring to their installation instructions. The system must be connected to and controlled with a thermostat and sensor.

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, clips, materials or tools.
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.
The installation of the system must comply current edition of building regulations.
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.
i Ensure the subfloor is prepared to an SR1 standard. The subfloor must be clean, level, smooth, dry, frost-free, solid, suitably weight-bearing and dimensionally stable.
i Insulation layers used should be chosen and installed in line with building regulations and standards. Contura can also be used on pre-insulated subfloors.
i Contura can be installed on both concrete or suspended timber subfloors. Timber subfloors must be installed as per building regulations and have a structural floor deck to support the Contura system
i Install the floor sensor centrally between two parallel runs of pipe and away from other heat sources such as hot water pipes, lighting fixtures, chimneys etc.
Before installing the floor finish, its suitability for use with underfloor heating and its maximum operating temperature should be checked against required operating conditions. Ensure the heat output of the floor meets your requirements.
i Ensure adhesives, grouts, glues and screeds used are compatible with underfloor heating.
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
It is recommended that all furniture installed over underfloor heating has feet, maintaining a minimum 50 mm ventilated space above the floor to allow heat flow into the room.
DO NOT use metal clips to secure the pipe to the subfloor.

The concrete subfloor must be clean, level, solid, structurally sound and dimensionally stable. Ensure the subfloor is prepared to an SR1 standard (SR1 - the maximum permissible departure over a 2 m straight is 3 mm).

It's important to note that concrete oversite and beam & block subfloors typically need a blinding layer before installing DPM or Contura Insulation panels due to surface regularity requirements as the panels must be fully supported.

Any materials on or within the subfloor must be suitable for supporting underfloor heating systems. If using temperature sensitive materials, such as damp proofing or tanking systems, contact the manufacturer for advice.

Where tiles are to be used, ensure that the subfloor meets the local tiling standard requirements.

Ensure suspended timber subfloors are prepared in accordance with national standards and manufacturer instructions are properly followed to avoid subfloor movement to prevent any damage to the system.

Do not commence installation without ensuring that the resulting floor construction will meet the requirements of the floors intended use and its finish.

- Service pipe tracks will need to be routed into the Contura panels. Contura panels should be installed upside down in service pipe locations and then service pipe locations marked with a pen, maintaining a minimum bending radius of 100mm and a spacing of 30mm until the manifold. - The tracks must then be routed out using a 16mm full radius router bit. Once routed, clear the debris from the location.

Tracks should be routed at 30mm centres with the last 500mm of pipe tapering down to 25mm centres as it reaches the manifold.

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.

q = Specific Heat Output, W/m2k	H = System Performance Factor, W/m2K
Twater = Mean water Temperature T	air = Room Air Temperature

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 Warmup Contura, fitted with pipe at 200 mm centres, in a 21°C room heated with 40°C water is;

$$ q = 2. 2 2 \times (4 0 - 2 1) = 2. 2 2 \times 1 9 = 4 2. 1 8 W / m ^ {2} $$

Alternatively, using the system k_H value to calculate the required water temperature, knowing the required heat output:

$$ \mathrm{T} _ {\text { water }} = \left(\mathrm{q} / \mathrm{k} _ {\mathrm{H}}\right) + \mathrm{T} _ {\text { air }} $$

Example:

The water temperature required to produce a heat output of 55 W/m ^2 , through a 3 mm thick ≈ 0.25 tog LVT floor finish, over Warmup Contura, fitted with pipe at 200 mm centres, in a 22°C room is;

$$ T _ {\text { water }} = (5 5 / 3. 0 3) + 2 2 = 1 8. 2 + 2 2 = 4 5. 2 ^ {\circ} \mathrm{C} $$

Close-up of white concrete slabs with curved and rectangular cutouts, no text or symbols visible

Floor sensor setting for target heat output

The room with the highest water temperature requirement sets the design water temperature for the whole system based on the calculations from the previous section.

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 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 ).

Specific Heat Output, W/m²

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.
