FAQ - Fragen und Antworten


All electrical heating sources such as heating cables, heating mats, heating foils, heating fabrics, aluminium heating mats etc. that can be used as floor heating must be thermally monitored and controlled. This must be done by means of an external sensor (also called a floor sensor). Only in this way can a desired floor temperature be set constantly and the maximum temperature required by the floor covering manufacturer be maintained.


The warm-up time of the floor depends on:

  • material of the soil
  • concrete or wood
  • choice of sound insulation 2mm / 5mm
  • flooring
  • performance of the infrared heating foil.

Thus, the warm-up time can be from a few minutes to an hour.


All floor coverings that have an EU CE marking and are suitable for underfloor heating can be used. This is indicated by a corresponding symbol on the product. It is important to observe the maximum permissible temperature of the floor covering 


In addition to a normal fuse, the electrical supply line must also be protected by a RCD.


  • For thin vinyl floors without backing board or carpet flooring, we recommend a maximum output of 100W/m².
  • For vinyl floors with backing board, wood or laminate flooring, we recommend a maximum output of 130W/m².
  • For installation under concrete or tiles, a power of 160 to 220W/m² can be used.

Other factors such as room size, insulation and the number of exterior walls must be taken into account.


For laminate, parquet and vinyl floors with a backing board, you can use a laminated / reflective underlayment with 3 or 5mm thickness. 
For thin floor coverings such as PVC, carpet or vinyl without a backing board, use a laminated / reflective underlayment  with 1.5mm thickness. 

Please also observe the manufacturer's instructions for the selected floor covering.


When using perforated heating elements in tile adhesive or levelling compound, the RCD may trip prematurely. The drying time of the applied material must be taken into account. Increased moisture content can cause the RCD to trip. After an appropriate drying time, tripping should no longer occur. 


The underlayment  or also called insulating underlay, which is laid under the carbon heating foil or also aluminium heating mats, does not have to be suitable for underfloor heating. This product specification refers to classic water-guided underfloor heating, where the impact sound insulation is supposed to let the heat through.

Our heating solutions, on the other hand, are laid directly on the underlayment and under the floor covering. This makes underlayment  (not suitable for underfloor heating) the ideal component. These underlays have a much better insulation value and ensure that the heat is conducted upwards towards the floor covering as far as possible.


Yes, the "normal" line is designed for 16 A (3680 Watt) load. However, it is important to consider how many consumers are connected to this circuit. If you want to lay out your entire house with infrared heating foil, it is recommended to provide individual fuses for the circuits. If you have any questions, an electrician should be consulted.

When the desired temperature is reached, only the heating element of the Ballu BKX electric fan heater is switched off. The fan continues to run to ensure optimum heat distribution in the room air.

If you have already made any settings, we recommend that you first reset the ETO2 ice and snow melt control to the factory state.

This is done under Setup → Factory Reset → Reset. Then restart the unit via Exit → Restart.

After the restart, select the following settings:

  • Celsius
  • Sensor 1: ETOG
  • Sensor 2: OFF
  • Outdoor Sensor: OFF
  • Application: ELECTRIC 1-ZONE

In this operating mode, all 3 relays are always switched through when the switching thresholds are reached.
The display shows "ZONE 1 HEAT" with "ON" and "ZONE 2 HEAT" with "OFF".


Heating with electricity is only expensive if electricity is used to heat the air. The infrared heating foil works on the principle of radiant heat and dispenses with the bad heat transfer medium - air.

In principle, you do not need any in-depth specialist knowledge to install infrared heating foil or heating mats. However, the installation on the 220V mains must be carried out by a qualified electrician.


We attach great importance to individual advice and customer-oriented service. We therefore offer you project planning completely free of charge and without obligation.

To the project planning


The maximum thermal resistance of the floor covering must not exceed the value Rλ = 0.15 m2K/W. Often, only the thermal conductivity value is specified for floor coverings. To calculate the thermal resistance from this, the material thickness of the floor covering must first be converted into metres (m) and then multiplied by the thermal conductivity value. 

We charge a flat-rate conversion fee in the following cases:

  • In the case of a heating film web custom-made for the customer, which has a length deviating from the standard and for this reason must be electrically insulated over the complete web width.
  • In case of a custom-made heating foil web for the customer, which is to be provided with a longer connection cable. The standard length of the connection cable per heating film track is 2.5 meters. The additionally required cable is also charged separately.

Whether a floor covering is suitable for underfloor heating depends on the thickness of the material and its thermal conductivity. The thermal resistance can be determined from these two factors. First, it is necessary to convert the thickness (d) of the material into metres. Then this value is divided by the thermal conductivity (λ) to obtain the thermal resistance (R).

The calculation formula is therefore R=d/λ

For a floor covering to be suitable for underfloor heating, the thermal resistance of 0.15 m²K/W must not be exceeded.

Below are some reference values:

Material          Strength Thermal resistance
Laminate 9 mm 0,044 m²K/W   
Parquet 8 mm 0,038 m²K/W   
Cork (on backing) 11 mm 0,129 m²K/W   
Vinyl (on backing) 7 mm 0,016 m²K/W   
Design floor 4 mm 0,032 m²K/W   
PVC 2 mm 0,010 m²K/W   
Linoleum 3 mm 0,017 m²K/W   
Natural stone 20 mm 0,017 m²K/W   
Ceramic tiles 13 mm 0,012 m²K/W   
Fine stoneware 10 mm 0,010 m²K/W   
Carpet 8 mm 0,010 m²K/W   
Nadelvlies 7 mm 0,012 m²K/W   


** These are only indications. Please refer to the data sheet of your desired floor covering for the exact specifications.



Thermostate

Alle Sprachen

The position of the thermostat should be in a freely accessible place and, if possible, not be exposed to direct sunlight. A cold outside wall should also be avoided if possible.

The Mi-10 thermostats have a so-called potential-free switching contact, which initially does not output any voltage. It is therefore necessary to connect a bridge from the phase (L) at 230V AC or plus (+) at 12/24V DC to one terminal of the switching output. One connection wire of the heating film / heating mat is then connected accordingly to the other terminal of the switching output. The other connection wire of the heating film / heating mat is connected directly to the neutral conductor (N) at 230V AC or to minus (-) at 12/24V DC.

The KTY semiconductor sensors (149300 remote sensors) from Gira have different resistance values compared to conventional NTC sensors with 10kOhm or 12kOhm, for example. Gira has therefore published a resistance table for this. 

 5 °C - 85.27 Ohm
10 °C - 66.78 Ohm
15 °C - 52.33 Ohm
20 °C - 41.27 Ohm
25 °C - 33.00 Ohm
30 °C - 26.28 Ohm
35 °C - 21.13 Ohm
40 °C - 17.08 Ohm
45 °C - 13.84 Ohm
50 °C - 11.27 Ohm

Suitable replacements are the thermostats MCD4, MCD5, OCD4, OCD5, MWD5 and OWD5 from the manufacturer OJ Electronics. In addition to the common NTC sensors, these can also be operated with other sensor types. To do this, the sensor type must be selected as "User-defined" in the technical settings and the resistance values of the sensor at 5 °C, 20 °C, 25 °C and 30 °C must be entered.

No, normally closed actuators (NC) of an underfloor heating system and many boilers and heaters can also be connected to the thermostat. Please check the manual of your heater beforehand to see if it has a control input for a thermostat. 

Normally, these units have a control input for an external thermostat. However, you must pay close attention to whether this control input must be switched via a potential-free switching contact, i.e. without mains voltage applied, or whether it can be provided directly with mains voltage. You will find precise information on this in the manual of your heater. If anything is unclear, a qualified electrician should be consulted for assistance. 

Yes, normally closed actuators (NC) can be connected to the thermostat. Actuators with 230V voltage can be connected directly, for actuators with other voltages (e.g. 12 or 24V) a corresponding power supply unit is required.

A potential-free switching contact is a switching output that is not live. This is comparable to a standard light switch to which no cables are connected.

A potential-free switching contact offers the advantage that a wide variety of consumers can be connected. For example, devices with low voltage such as 12V / 24V / 36V or 230V mains voltage can be switched (provided the appropriate voltage source is available). In addition, a potential-free switching contact can also be used as a signalling contact, e.g. for a higher-level control system.

For our thermostats that have a potential-free switching contact, you will find a suitable connection diagram in the online shop and in the corresponding operating instructions.


The NTC floor sensor is a temperature-dependent resistor. The polarity does not matter when connecting to the terminals provided for this purpose.

We recommend always installing the floor sensor in a corrugated tube / empty tube so that it can be easily replaced in case of damage. The empty conduit has a diameter of approx. 16mm. Appropriate recesses must be chiselled out in the wall and floor. 

The sensor itself should protrude at least 10cm on or under the heating film so that the temperature can be measured correctly. If a heating mat is used instead of a heating film, the sensor should be positioned between two heating wires. Here too, the sensor should protrude at least 10cm into the heating area.


The following table shows which of our thermostats are compatible with which resistance values of floor sensors.

Heizfolie

In the striped carbon foil heating the copper traces must run each left and right at the edge of the page to be isolated. For the full-surface carbon heating foil, the entire cutting edge must be insulated.

Usually this is harmless as long as the damaged area is isolated. But beware: If the copper strip is defective or damaged, the foil is no longer useful and must be disposed of. However, you can cut the film from the damaged spot and then of course use it again. Repairs and modifications may only be carried out by a qualified electrician.

For most heating films, it does not matter how it gets laid. The type designation should be read from above.

An infrared heating film for floor mounting should have a thickness of at least 0.3mm, otherwise it cannot withstand the pressure loads that occur. A thinner infrared heating foil is only suitable for ceiling mounting. A high-quality infrared heating foil has multiple insulation and robust copper tracks for current distribution. In addition, temperature-resistant and solvent-free adhesives are used. Our high quality standards enable a service life of up to 50 years.


Yes, Heating Film Underlayment has the following functions:

  • levelling out unevenness
  • additional thermal insulation
  • impact sound reduction
  • promotes upward radiation
  • facilitates installation by allowing cables and connectors to be recessed/sunk.

In our shop you will find insulating underlays for common floor coverings such as laminate, parquet, vinyl on HDF or vinyl. The underlay/impact sound insulation must meet the requirements of the floor manufacturer.

All underlays offered by us meet the standards applicable in the EU with regard to compressive strength and fire behaviour.


The heating film may only be operated in conjunction with a suitable thermostat, which ensures thermal monitoring by means of an external sensor (floor sensor) and also enables the floor temperature to be limited to the maximum temperature specified by the floor covering manufacturer.

The infrared heating foil can be laid as a full-fledged heater on the entire floor * or on the ceiling.

* Only under furnishings that are at least 7cm above the floor. Such as. A bed on feet / stilts. ONLY the full-surface carbon heating foil may be laid under fixed furnishings.

The infrared heating foil is mainly installed as a supplement to the existing heating system in order to use the pleasant infrared heat in certain areas.


The carbon heating film is on the rise. That is why there are currently low-voltage versions on the market, 12/24/36/42/48V and the 230V version for our mains supply. There are two principles of construction, the striped version and the full-surface version.

The most common widths of the heating strips are 50,80 and 100cm but 25, 30, 43, 60 etc. are also in circulation.

The power consumption is mostly given for one m².

We carry the carbon heating film in 80,100,130,160,220,400,500Watt/m² and more in our assortment.


Yes, a kind of carrier layer such as Fermacell, OSB boards or Mi-board has to be laid over the heating foil. This carrier layer has the function of mechanically protecting the carbon heating foil and absorbing the infrared rays as a heat transfer medium and distributing the heat evenly. The thermal resistance of the entire structure has to be considered. This must not exceed a value of Rλ = 0.15 (m²K)/W.


Infrared heating film is the thinnest version of an electric heating source. Its low installation height makes it very popular for installation underneath the floor covering. The infrared heating film heats up evenly and thus provides pleasant floor warmth over the entire installed surface.

  • The outer copper tracks serve as conductors.
  • Thin electrical wires conduct the current onto a carrier material. Depending on the heating film, this consists of carbon or graphite.
    The respective heating power of the heating film is determined by different mixing ratios.
  • The heating film can be individually shortened to the desired length at the intended cutting points.

Taking into account the DIN VDE 0100-701 standard, electrical underfloor heating systems with an operating voltage of up to 25V alternating voltage (AC) or up to 60V direct voltage (DC) may also be installed in a shower without a tray. The following points from the standard, among others, must be taken into account here:

  • 701.30 Determination of general characteristics 
    Chapter point 701.30.103 defines that showers without a tray belong to area 1 and not to area 0.
  • 701.5 Selection and installation of electrical equipment 
    Under chapter point 701.512.2.4.101.3, area 1 is defined in such a way that electrical equipment protected by extra-low voltage by means of SELV or PELV may be installed there. Permissible are 25V alternating voltage (AC) or 60V direct voltage (DC) and the power source must be installed outside areas 0 and 1. Further information can be found in chapter 701.414 - Protective measure: protection by extra-low voltage by means of SELV or PELV. 

Yes, the striped carbon foil can be shortened every 25cm or 2cm, depending on the type. The full-surface carbon foil can be shortened at any point.

A newly laid tile covering still contains a lot of water, which must first evaporate. Therefore, the function of the underfloor heating is hardly noticeable during the first 14 days. In addition, the underfloor heating should only be put into operation after the tile adhesive has completely hardened (please follow the manufacturer's instructions).

The resistance of each individual heating cable should be measured and documented with a multimeter before installation. For a short-term function test, the individual heating cables can be connected directly to the 230V mains. As soon as the cables heat up, however, they should be disconnected from the mains again. Permanent operation without thermostats is not permitted and can lead to damage.

After each heating cable has been measured and tested individually, they can be laid out and wired. It should be noted that the heating cables may only be connected in parallel and not in series. Afterwards, the total resistance across all heating cables should be measured again with the multimeter. A final function test by applying the mains voltage again is advisable.

After all steps have been carried out, grout or tile adhesive can be applied.


The Snow Melting heating mats can melt up to 6 cm of snow per hour. In addition, the heating mats can also be placed on already formed ice to melt it.
 

The loop distance of the heating cable should be between 8cm and 12cm. If the loop spacing is too small, the heating energy per square metre is unnecessarily high. If, on the other hand, the loop spacing is too large, noticeable cold bridges can occur.

Before installation, the resistance of each individual heating mat should first be measured with a multimeter and documented. For a functional test, the individual heating mats can also be connected directly to the 230V mains, i.e. without thermostats. As soon as the mats heat up, however, they should be disconnected from the mains again. Permanent operation without thermostats is not permitted and can damage the heating mats.

After each mat has been measured and tested individually, they can be laid out and wired. It should be noted that the heating mats may only be wired in parallel and not in series. Afterwards, the total resistance across all heating mats should be measured again with the multimeter. A final function test by applying the mains voltage again is advisable. 


The coloured connection cables (black, blue, green-yellow) can be lengthened or shortened as desired, as they are normal power cables. However, nothing may be changed on the heating wire, as the cable length is precisely calculated. Shortening or lengthening the heating wire would interfere with the function or may even cause damage.

When the TH400 towel heater shows the abbreviation "BP" in the display, the unit is in the so-called bypass mode. This mode is intended for control via an external thermostat. Normal operation via the unit buttons or via smartphone app is not possible in bypass mode.

To exit bypass mode, press the + and - buttons simultaneously. The "BP" display then goes out accordingly. 

If the process is repeated, the bypass mode can be activated again. 


To reset the TH400 towel heater to the factory settings, please proceed as follows:

- Switch off the unit
- After a few seconds, switch the unit on again
- Press and hold the "Timer" button on the touchscreen for at least 5 seconds
- A slowly flashing WLAN display confirms the successful reset
 


As a rule of thumb, about 60-80 watts of heating power are required per square metre (m²) of room area in a normally insulated living space. The calculation becomes even more precise when the room height is taken into account. The rule here is that an average of 30 watts of heating power is required per cubic metre (m³)

Infrared heating panels are completely maintenance-free and do not require any maintenance measures. Occasional cleaning with a damp cloth is possible, but not necessary.

No, the infrared heating panels must not be installed directly or covered, as this may lead to a build-up of heat. Although a built-in temperature fuse protects the units from overheating, they should not be installed or covered under any circumstances.

Yes, chairs and tables with legs may stand on the heating carpet. Only pieces of furniture with a large base may not stand on the heating carpet, as otherwise heat can build up.

No, office chairs with castors must not be used on the heating carpets. The point pressure load is very high and the constant movements would put a lot of mechanical stress on the heating conductors and could break them.
