UNDERFLOOR HEATING INSTALLATION GUIDE
Please ensure you read the following installation guide before installation.
The illustrations in the following installation guide are indicative – any colour and/or number of adhesive tape lines of mat may vary.

PRODUCT IDENTIFICATION

The installation guide is applicable to the follow- ing products: Heat My Home heating mat with cold tail. The heating mat consist of heating cable, mesh, and double sided tape. Mat width is 0,5 m. Mat length is depending on the size of the mat. Mat power is 100, 150 or 180 W/m² at 230 V.

IMPORTANT INFORMATION

• The electric connection must be carried out by a Qualified Electrical Installer in accordance to the national wiring legislation. Other rules applicable for Underfloor Heating Systems must be met.
• Never cut, shorten or cross the cable on the mat.
• To prevent the system from overheating the cable and both joints must be fully encapsulated in the covering material. This applies to the full length of the heating cable and the two joints.
• Always turn off the power when working with mains installations.
• Verify that resistance and insulation values are correct. Fill in the readings in the warranty certificate in the section “Warranty”.

TECHNICAL DATA

APPLICATIONS

The Underfloor Heating System is designed for indoor use only and is to be fully encapsulated in a layer of screed, tile adhesive, cement or levelling compound.
Underfloor heating installed beneath wooden or parquet, laminate and carpeted floors must have the floor temperature suitably limited.
Heating mats are well suited for quick and easy installation on large areas and in rooms with no or few partitions or protrusions.

INSTALLATION PREPARATIONS

PLAN, DOCUMENT AND VERIFY
The Required Wattage per square meter, should be determined for the specific installation to choose the best suited product range.
The Heated floor area must also be calculated so that you can choose the most suitable sized heating mats for your application.
DETERMINE REQUIRED WATTAGE PER SQUARE METER (W/m²)
The Required W/m² is depending on the specific conditions in the surrounding building and the room it is being installed in (Tab.1).

Area of application| Typical wattage requirement )| Max wattage with higher power requirement )
---|---|---
Floor heating e.g. Nordic countries| Low-built underneath wooden floor| 80-100 W/m²| 160 W/m²
Low-built underneath tiles or similar| 100-150 W/m²| 200 W/m²
Floor heating e.g. UK and Ireland| Low-built underneath wooden floor| 140-160 W/m²| 160 W/m²
Low-built underneath tiles or similar| 150-180 W/m²| 200 W/m²

Tab. 1. Typical Wattages per square meter
You should ensure the room insulation level is as high as possible to avoid unnecessary energy consumption – 100-130W systems should only be used in very well insulated rooms.
DETERMINE HEATED FLOOR AREA (m²)
When planning a floor heating layout consider the following to avoid damaging the cable in the mat and ensure trouble free use and long lifetime. Consider the following guidelines making a drawing of the room and positions of the mat runs (see fig. 1 as example).

• Allow a border of 2-4 cm at the perimeter of the room without any heating.
• Keep the heating cable at least 3 cm from any conductive part and heat source. i.e. water pipes, *) The heating requirement of buildings and office facilities can vary, based on insulation levels and increased power need such as exceptionally high or low insulation levels, large window areas, high ceiling height and exceptionally low ambient temperatures.

luminaries and chimneys.

• Heating cable must be installed at least 10 cm from drains and similar places that carry a higher risk of moisture and water to be present.
• It is not allowed to install the mat under fixed objects such as toilets, close-fitting cupboards and similar.

An object lifted up on legs min. 6 cm from the floor surface, so air can move freely under it, is not considered a fixed object.
The drawing will also act as a guide during the actual mat installation and later serve as documentation of how it is installed and laid out. This is useful in case of future changes or maintenance work. Now the heated floor area has been established.
To determine which mats fit the heated area the best, note the following:
The mat mesh can be cut to make the mat lanes fit the room. The mat width is 0,5 m and it makes sense to work out if runs in one direc- tion provide better coverage than runs in the other.
You can free the heating cable from the mat if needed. Keep in mind, that the heating ca- bles must never be cut, shortened or crossed. Therefore, never purchase too big a mat, that will not fit the room floor surface.
CALCULATING COVERAGE – a fast and rough guide:
Although 100% coverage with heating mats is achievable, a border of 2-4 cm is recommended around the perimeter of the room as the heating cables should not touch the walls. In normal circumstances we would recommend deducting between 5 and 10% from
the total free floor space that you wish to heat, to give you the square meters of heating mat that you should install.
Our recommendation is to deduct:

• 10% for fitting space in rooms up to 15 m² ,
• 7% for rooms between 16 m² and 25 m² ,
• 5% fitting space for larger rooms.

Multiple mats can be combined to provide a good coverage in a room, but the mats must always have the same Wattage output per square meter. Also it is recommended to install as few mats as possible.
MAT COVERAGE – a precise guide:
The mats can be positioned in any direction in a room, but it makes sense to work out if one direction provides better coverage than the other. For instance if a room is 3,6 x 2,4 m you get 7 runs of mat 2,3 m long running the mats length ways or 4 runs of mat 3,5 m long if you choose the other way. The first option provides a better coverage of the floor. To decide the best coverage, the available product sizes within in the chosen W/m² must be observed. It may prove optimal, to change directions once more. A mat may never be shortened, since shortening the heating cable will ruin the product.
You must determine the connection point of the thermostat and location of floor sensor and include it in the drawing (see Fig. 1 as ex- ample).
THERMAL RESISTANCE AND POWER
The maximum output beneath insulative floors such as carpet, vinyl, engineered board and laminate is 160 W/m² – materials such as tile and stone is max. 200 W/m². The thermal resistance (insulation) between the heating cables and room must not have an insulation value higher than 0,125 m² K/W (R-value). In other words the layers above the heating system must not prevent heat from rising into the room.
Thermal resistance of typically floor types can be seen in Tab. 2 below:

Typical insulating values: (R-values)

Thin floors with i.e tiles, vinyl:| 0,035 m²К/W
Medium thickness floors i.e. linoleum, vinyl:| 0,040 m²К/W
Floors i.e. wooden, carpets, parket:| 0,125 m²К/W
Thick floors i.e. wood-fibre, thick carpets:| 0,175 m²К/W

COVERING MATERIAL
The heating mats must be covered with a suitable material i.e. tile adhesive, cement, screed, levelling compound suitable for use together with Electrical Underfloor Heating Systems.

• Use a suitable primer.
• Covering material must have a dry density min. 1500 kg/m³.
• Covering material must have a heat transmission of minimum 1 W/m K.
• The layer of covering material must have a thickness of at least 7 mm. Wooden parquet, linoleum or wall to wall carpeting min. 12 mm.
• Covering material encapsulating the heating cable must have uniform properties.
• Covering material must not be insulating, contain air bubbles or have any other insulating properties.
• Covering material must encapsulate the heating cable fully.
• Make sure the building requirements for the specific installation are made according to legislation i.e. installation of a damp course in wet rooms.
• Follow the instructions on the covering material package thoroughly. It is important that the floor is fully dried out before you turn on the power. Levelling compounds may take up to 28 days to dry.

GENERAL INSTALLATION GUIDELINES

1. Read the section “Important information” at the start of the user manual and installation guide.
2. Plan and prepare thoroughly before installation begins.
3. Install the mat on solid surfaces only. The floor on which the mat is installed must be rigid and stable.
4. Installation of floor heating and terminations on timber constructions should be made so relative movements in the floor will not damage the heating cable.
5. Consider your choice of thermostat and install a suitable floor sensor. It is recommended to use a conduit pipe for the floor sensor.
6. The product joints must not be exposed to strain or pressure. The joints on the heating cable must not be bent and a minimum of 25 cm of cable on each side of the joints must be placed in a straight line. The joint and the end termination are to be con- sidered part of the heating mat. The joints must not be covered by tape, be left in an air pocket or be pushed into an insulative material.
7. Small scratches and careless handling of the cable can reduce its lifetime. Therefore, pay attention when laying out the underfloor heating system.
8. Always use rubber soled shoes if you have to walk on the cables.
9. Avoid damage to the cable, such as dropping sharp objects on it, careless pouring of covering material, creasing or crushing of elements.
10. All heating cable as well as both joints must be fully encapsulated in covering material.
11. The ambient temperature must be above 5 ◦C when the floor heating mat is installed.
12. The cables may never be placed closer than 3 cm from each, or be bent below a radius of 6 x cable diameter i.e. min. bending radius: 6 x 3,5 mm = 21 mm

The location of the floor heating system should be documented next to consumer unit. The documentation must inform that there are conductive parts in the building. The installer shall provide a drawing or photo containing details of the placement of the floor heating. The warranty certificate must be completed and used as documentation.
TESTING
Measure the resistance between the heating wires and the insulation resistance to earth. Measure at least twice on the cable. In this way, you ensure that you do not continue to work with a faulty cable. Write down the measured result and keep it along with other doc- umentation. The insulation resistance must be >100 MΩ after one minute at minimum 500 VDC. If the ohm resistance deviate from the data given in the product label, the element is likely to be damaged and must be exchanged.
Measure the resistance and the insulation resistance:

• before starting cable installation
• once the cable has been placed
• once the installation has been completed Fill in the results in the Warranty Certificate.

The power supply system, connected to the cable, must always contain a Residual Current Device (RCD) max 30 mA 230 Vac.
At no point should any cable be connected to the mains to test it.

INSTALLATION GUIDE

Ensure all necessary preparations have been made as described in section “INSTALLATION PREPARATIONS” and “GENERAL INSTALLATION GUIDELINES”, and use the prepared drawing with layout.

1. Measure the resistance and the insulation resistance before starting mat installation and complete the Warranty Certificate.

2. Prepare place of installation
   Remove all old installations if relevant If necessary fill up any cavities around hoses or drains, or along walls

3. Mill a cavity in the wall to allow a cold supply line to run to the thermostat. A cable pan is also a usable solution.

4. Mill grooves for cold/heating cable joint and end joint. The cable should be kept strait for min. 25 cm each side of a joint. Make sure to make room for the covering material to fully encapsulate the joints by at least 10 mm either side of the joint. Groove depths made in accordance with the total construction height (Fig. 2).

   ---|---

5. Mill a groove for floor sensor conduit pipe if used. Depth in accordance with the total construction height.

6. Make sure that there are no sharp edges, leaves, dirt or foreign objects on the subfloor. The subfloor shall be even, stable, smooth, dry and clean.

7. Prime your floor with suitable primer (Fig. 3).

8. Roll out the mat onto the floor mesh side up until you reach the wall or an obstruction (Fig. 4). Cut-and-turn the mat to continue laying it. Do not cut the cable (Fig. 5). Repeat this until you have covered the floor (Fig. 6).

9. If you’re using multiple mats we recommend fitting the largest mat first. We re- commend rolling the mat out to the furthest point of the room and then working the mat back towards your starting point. You must make sure you do not “paint yourself into a corner” or leave isolated areas unheated.

10. If you have a small amount of mat left over when you have covered the floor you can cut the mesh from side to side between each run of heating cable, and shuffle the mat together shortening the distance between each cable run to use up the excess mat. Alternatively, if you don’t have quite enough heating mat you can cut the mesh and space the cable runs slightly further apart to cover a larger area.

11. Place and fix conduit pipe or floor sensor if no conduit pipe is installed. Make sure to position the pipe/sensor between two heating cables (Fig. 7).

12. Once the mat(s) is positioned in accordance with your drawing and well fitted to the floor surface, fix the mat runs to the floor by removing the liner from the double sided tape and lightly press down the tape. Continue the procedure until the all of the mat has been fixed (Fig. 8).

13. Measure the resistance and the insulation resistance once the cable has been placed and fill in the Warranty Certificate.
    Note: if the result varies from previous measurements, it indicates the integrity of the product is compromised and the product should not be used.

14. Pour the compound over the heating mat:
    • The tile adhesive, latex or levelling compound must not contain any sharp objects.
    • The compound must be sufficiently wet, even and free of air cavities.
    • Pour at a moderate speed to prevent the heating cable from moving, with tile adhesive smooth it over the cable care- fully
    • Make sure that you do not damage the cable with your tools or container holding the covering material.
    • Allow the compound to cure before power is applied to the cable. This is important to ensure optimal cable lon- gevity. The curing process may take up to 28 days.

15. Measure the resistance and the insulation resistance once the installation has been completed and fill in the Warranty Certificate.
    Note: if the results vary from previous measurements, it indicates the integrity of the product is compromised and the product should not be used.

CONNECTION, OPERATION AND APPROVAL

• The installation must be measured and connected by an authorised electrical installer only.
• Always use a thermostat with the temperature limiting system initially set at a maximum of 27 °C if carpet, wood, vinyl or laminate is used as the flooring. Follow the guidelines of the supplier.
• Local regulations, rules and this guide must be adhered to.
• The heating cable requires earthing and a 230 V 30 mA Residual Current Device.
• Do not connect the heating cable directly to the mains. It must be controlled by means of a thermostat.

A visible sign, e.g. mounted by the electric panel, must be provided to inform that electric heating is installed.
THERMOSTATS
Ask an authorised electrical installer to prepare main supply and connect the thermostat. If more than one floor heating cable is connected to the thermostat the connection must be made in parallel.
The Underfloor Heating Systems must be connected to a two-pole contactor if required by local legislation.

MAINTENANCE AND USE

Consider the risk of thermal blocking when placing furniture on the heated floor, the floor must never be thermally blocked by items which would prevent the heat rising into the room which could cause the floor to overheat. An object lifted up on legs min. 6 cm from the floor surface, so air can move freely under the object, is not considered a fixed object. Run the Underfloor Heating in a way that takes up the lowest energy consumption possible, while maintaining comfort.

APPROVALS AND COMPLIANCES

The system you have purchased is approved to the very latest regulations including EN60335-2-96:2002 and EN60335-1:2002 part A13:2008.
