HEATING MATS |
MHH double-conductor heating mat
Double-conductor heating mat is made of a shielded twin-core cable, fixed on the fiber mesh. One end of the heating section are fitted up with cold lead and reliable coupling which passed factory testing and sealing end. To differentiate mats according to space and power output types various cable sheath colors and markings are used. Specifications of heating mats are given in the Appendix
(please, refer to paragraph 10.3). |
 |
MHH heating mat is manufactured and tested in full accordance with IEC (International Electro technical Commission) Global Quality Standards. High reliability of mats is ensured by ultra-thin screened cables with diminished effect (linear power), which are fixed on the mesh with constant wire spacing. Rated linear power of cables used in mats is lower than in standard cables used for under floor heating but power output of each square meter of heating mat is about 140W that ensures highly uniform and efficient heating. Thanks to the cable fixation on the mesh there is no need to adjust the wire spacing and to fix the cable on the floor surface which can by chance lead to the damage of the wire during the process of installation. Warm Star mats are produced out of high-quality materials provided by world leading plastic manufacturers.
MHH heating mat consists of double-conductor heating cable, one coupling, installation wires and sealing end.
Heating conductor and screen are reliably connected with two installation wires, which are designed to connect heating section to thermostat and protective earthing.
For correct MHH mat connection, please, pay attention to coloring of cold leads.
Blue and brown installation wires are connected with heating conductor and are to be connected to the thermostat. Ground bus is to be connected to the earth loop of the building (or to zero wire of power network).

BEFORE THE INSTALLATION |
Before Warm Star system installations please, make sure that you chose the system suitable for your premise and desired type of heating (main or comfort heating).
| Heating Mat Placement
It is recommend to lay heating sections on the sub floor area free from fixed furniture. Place heating mats in the usable area: where you walk, where heat radiation is effective. To fit mat to the heated area configuration it is necessary to cut mesh into fragments. When cutting take care not to cut or damage the heating cable. Never allow strips of mesh to overlap. Never use one and the same mat for heating different types of premises (e.g. bathroom, hallway or kitchen). It is not recommended to use the same mat for heating premises with different floor constructions. For this purpose independent mats should be installed along with the thermostats. If it is necessary to heat balcony, terrace, interior garden, premises with many windows, open doorways, archways, premises with ceilings over 4 meter high, please, consult our manager who will offer you suitable system to heat the premise required.

ELECTRICAL WIRING AND THERMOSTAT PLACEMENT |
| According to Electric Installation Code
(edition of 2001) standard electrical wiring
withstands the following currents and
appropriate power loads (table 1):
It is recommended to use a separate circuit
and separate safety device to power
heating systems with power over 2kW. Warm Star
systems are to be connected via Ground Fault
Circuit Interrupter (GFCI) which actuating rated
current doesn't exceed 30 mA. This is a small
device mounted on the panel board which controls safety of your equipment thermal insulation.
|
 |
When mat is installed in damp premises (bathrooms, saunas, swimming pools), heating mat screen must be connected to earth lead of supply network. To this wire must be connected all available metal parts: metal shower trays, metal frames of shower cabins, etc. Choose thermostat location. It should be installed in the most convenient place so it will not interfere with furniture disposal.
Thermostats controlling heating in damp premises (bathrooms, toilets, saunas, swimming pools) must be installed outside of such premises.

WARM STAR INSTALLATION |
Using this Manual you can install Warm Star
heating system by yourself. We strongly
recommend to entrust connection and powering
to a qualified electrician. High quality installation
and connection of the system ensuring its warranty
period can be performed by skilled specialists.
Remember that heating system durability is 99%
dependent upon its installation quality.
Here you will find description and illustration of
ultra-thin heating mat installation process. If you
need to heat a non standard premise, please consult our manager.
Step by step I_WARM heating system installation:
1. Prepare the space on the wall for thermostat mounting.
2. Chisel out channels for power supply wires, mat cold leads and temperature sensor in the wall.
|
 |
3. Chisel out 20x20mm long channel in the subfloor for floor sensor with connection wire placed in the corrugated tube.
4. Sub floor preparation: the floor should be even, secure, flex free, with appropriate bearing capacity. The surface must be dry, clean and free of grease, dust and sharp pieces.
5. Place temperature sensor into the tube, which is included in the I-WARM heating kit. The sensor must be placed inside the tube close to its end. Its connecting wire must be exposed from the opposite end of the tube.
The end of the tube with the sensor must be sealed to avoid ingress of cement mortar inside.
Place the tube with sensor in the chiseled channel and lead to the thermostat or to the terminal box. Tube bending radius must be 5cm minimum.
When corrugated tube is affixed to the wall and the floor, make sure that the sensor floats inside the tube.
For this partially pull out and then insert back sensor connection wire. This installation method allows sensor replacement without removing flooring material. Attention: The tube end with sensor connection wire should ends at terminal box or thermostat, otherwise it will be impossible to replace sensor without removing floor covering.
 6. Fill in chiseled channels with tile adhesive or grout.
7. Mark out area on the sub floor where the sensor will be fitted.  8. It is recommended to prime the subfloor with deepened grounding solution. Intensive absorbing surfaces should be primed twice. Let the surface get dry.
 9. Lay heating mat with mesh adhesive downside on the sub floor. Make sure that floor temperature sensor is centered between two heater wires.  12. Pour tile adhesive solution onto the mat leveling the solution from 5–8 mm and let it get dry according to the manual of preparation and application of tile adhesive used. We recommend using tile adhesive for under floor heating systems. Its preparation and application instructions are given in paragraph 10.4.  13. When tile adhesive is dry it is necessary to check whether heating mat or temperature sensor was damaged during installation, resistance reading of heating mat and temperature sensor should be taken. This reading should conform to their passport data.
14. According to Technical Certificates of mat and thermostat connect thermostat to the heating mat, and to temperature sensor; connect electric power to the thermostat; perform earthing.
15. Fill in with tile adhesive channels chiseled in the wall which leads connection wires, earth circuit, cold leads of the heating mat, temperature sensor connection wires in corrugated tube to the thermostat. |
 10. For single-conductor mat it is necessary to put cold leads to the thermostat via channels chiseled in the wall. Make sure there are no wire break offs. To check
the heating mat and temperature sensor was not damaged during the installation resistance reading of heating mat and temperature sensor should be taken. This reading should conform to their passport data.
 For double-conductor mat it is necessary to put cold lead to the thermostat via channel chiseled in the wall. Make sure there are no wire break offs. To check the heating mat and temperature sensor was not damaged during the installation resistance reading of heating mat and temperature sensor should be taken. This reading should conform to their passport data.
11. Sketch on the premise plan the diagram of heating mat, couplings and temperature sensor location.
16. Lay ceramic tile using new prepared adhesive solution. Maximum thermal resistance between heating mat and the premise produced by adhesive layer and ceramic tile should not exceed 0.06 m2K/W. Ceramic tile covering thickness shall be 5 mm minimum.
17. When tile adhesive solution is fully dry Warm Star ultra-thin under floor system is ready for operation. Turn it on following instructions of thermostat manual.
- Drying tile adhesive solution time is determined by instruction manual of tile adhesive used.
- Tiling directly onto the heating mat is possible. Be careful not to damage the heating cable. Adhesive layer thickness shall be 8 mm minimum.
- Heating mat shall be installed minimum 100 mm away from other heating appliances, e.g. risers and tubes of water heating system.  |

SYSTEM SWITCHING AND OPERATION |
Warm Star under floor heating system can be turned on when tile adhesive is fully dry. Switch the thermostat on and set the desired level of heating, using instructions of its Technical Certificate. During the first turning on of under floor heating system you can set the maximum heating level. It will accelerate floor heating. When the temperature gets to comfort level, reduce heating level as desired. When the system is turned on for the first time, the warm floor feeling will appear in some period of time. Mainly it concerns new build unheated premises. Please do not worry and let the system heat your premise. Bear in mind that Warm Star under floor heating system refers to comfortable heating type, it might not have enough power to heat cold premise when basic heating system is off.
HINTS AND NOTES
Due to automatic temperature regulation Warm Star system consumes exactly as much energy as it is necessary to maintain comfort level of heating. Thermostats installed in each room control heating independently that allows energy saving. I•WARM 720 is a programmable thermostat which especially allows energy saving for it automatically reduces or turns off heating when it is not necessary. The thermostat is more profitable in case of double-rate payment. If your premise stays empty in the cold season it is recommended not to turn off the system completely setting the thermostat on the minimal level. In this case the power consumption will be minimal and the room will not be chilled completely so you could heat it quickly upon return. Correct choice of I-WARM under floor heating system will allow you to reduce heating costs up to 50%. Heating mat must be placed minimum 30mm away from walls, fixed furniture or other items preventing effective heat radiation. During heating mat installation avoid direct contact with thermal insulation if it is of corrosive, hygroscopic, or flammable type. During the installation heating mat should not be exposed to oil, lubricant or similar substance influence. Braided shield of the mat cold lead must be securely connected to earthing terminal in the junction box or to adequate thermostat terminal. To avoid mechanical damage of the heating mat perform installation wearing soft elastic sole shoes or cover the mat surface with plywood boards or other material preventing heating cable damage when walking on it. Minimum mat installation temperature is 5 C°. Please contact me for technical advice and specifications. Michael Tel: 07715994065
