If you ask a heating expert which heating system is ideal, you will get a rather laconic answer - creating thermal comfort and well-being in individual rooms is a matter of heat transfer and distribution. If you want a more detailed explanation, you will get a little more specific - the ideal heating system is one with maximum heating surface, allowing even heat distribution at a low surface temperature. Large-area radiant systems - because that's whatwe're talking about - have taken up permanent residence in many countries in recent years.

Nowadays new buildings have very good thermal properties, and these systems, both floor or ceiling-mounted can easily heat the room to a desired temperature even at a low power consumption. In addition, by warming the structure itself, thermal comfort can be achieved already at a lower indoor temperature, and this becomes a considerable saving. A characteristic feature of these systems is a better temperature distribution in the room and a healthier climate (higher humidity, lower amount of dust in the environment). This type of heating is comfortable, economical and doesn’t disturb the interior at all. Ecofilm heating foils are a high-tech product designed for large-scale heating.

Ecofilm F – these floor heating foils ideally meet the technical requirements for installation under floating floors (laminate or wood) and thus provide the so-called large area heating, most suitable for these applications. Electricity is supplied to the heating foil by two copper strips and here is transformed without loss into thermal energy. This results in an efficient uniform heat distribution over the entire surface of the heating foil, while the surface temperature of the foil is low.

And what else currently makes the Ecofilm F so popular not only in Czech Republic, but also across the world?

1) Ecofilm F thin profile (thickness only 0'4 mm).
Unlike other heating systems (e.g. hot water tubular floor system), Ecofilm F can be very easily installed directly under the floating floor, without any deeper intervention into the original construction and limited height floor (so-called direct heating system, particularly advantageous for renovations, etc.).

2) Easy, fast and accurate installation.
Thanks to the special material composition, Ecofilm F can be shortened every 10 mm and can thus be precisely installed in the desired area. The connection is also quick, when after the installation different lengths of the heating foil are simply connected together using connectors and cables and the ends of the strips are insulated with insulating tape. Easy and time-saving installation of the heating foil compared to e.g. hot water underfloor heating significantly reduces installation costs, which plays a large role in the overall heating costs. Immediately after the installation and connection of the heating foil, the installation of the floating flooring can begin, which is particularly appreciated by the installers themselves.

3) High user comfort while saving electricity.
The Ecofilm F heating film is a perfect direct heating floor system with an even heat distribution throughout the area (so-called large-area heating). Compared to, for example, a hot water radiator system, heating foil can create an overall thermal comfort at a lower operating temperature of the heater, additionally saving space and thus improving the overall appearance of the room. Operating temperature of the Ecofilm F heating foil compared to 3 other heating media (e.g. water, oil) is highly controllable, which makes it possible to flexibly and, above all, precisely adjust the desired comfort or damping temperature over time. And accuracy of regulation is one of the main factors for saving the heating costs (temperature decrease for 1 °C will reduce the total cost of heating by up to 6 % of heating costs) and creating a stable comfortable environment.

4) Eco-friendly product
Ecofilm F is PVC and tin free.

5) Long life span and reliability.
On Ecofilm F 10 years of warranty are provided, however, the real life of the product is much longer (30-50 years). The product is tested according to European standards.

6) Resistance to mechanical damage
A major problem with the most underfloor heating systems is that they are rendered inoperative by mechanical damage (e.g. nail punctures, drilling, etc.) and costly repairs should take place. This is not the case with heating foils. Thanks to its protective construction Ecofilm F is resistant to mechanical damage. If this still happens and the heating film is punctured at a certain point, the film is not taken out of service in any case, only the heat output at that exact place will be reduced, which the human foot does not even recognize.

7) Technical maturity and adaptability.
Ecofilm F heating film meets all technical and design parameters, allowing its application directly under floating floors (such as continuous temperature rise and even temperature distribution). We believe for all these reasons it heats millions of meters square metres of floors throughout Europe and is highly recommended by the leading manufacturers of the floating floors.


Necessary steps before installing the heating foil Ecofilm F under the floating floor.

A. Choosing a heating concept

The user should think in advance about what kind of heating from Ecofilm F he expects. There are two options:

1) Ecofilm F as a supplementary heat source to other heaters in the room
With this heating system, the user is interested in not feeling uncomfortable cold from the floating floor. The overall thermal comfort in the room is mainly provided by the other 4 heaters in the room. This application is particularly well suited for older buildings where the owner or user is not interested in changing the heating system (e.g. gas central heating with a hot water radiator system, etc.), but is only interested in the tempering of the newly reconstructed floating floor for the sake of higher thermal comfort. If the user decides to use Ecofilm F only as a supplementary heating, it is not necessary to install the heating foil over the entire floor area, but only in frequently occupied zones (sitting and dining areas, work areas, etc.). For precise control of the heating operation of the underfloor heating system, it is recommended to use a programmable thermostat with a floor probe, which allows the heating mode to be programmed according to the user's requirements. The floor probe of the thermostat ensures that the temperature of the floating floor surface does not exceed the set limit. A wide range of suitable thermostats for underfloor heating can be selected from the FENIX product range.

2) Ecofilm F as the main heat source in the room
If the user decides that the Ecofilm F heating foil installed directly under the floating floor should be the main heat source in the room, it is important to check beforehand that the building is well insulated and, if necessary, to carry out additional insulation. This requirement stands out from the fact that you can choose a heating input of 60-80W/m2 for the installation of the heater directly under the floating floor. The reason for this is the limited thermal conductivity of the underfloor materials and the hygiene standard setting the maximum surface temperature of the floor in living rooms (28 °C). However, these limitations can be reduced by using two tools:

1) By insulating the building in a high-quality way, which will significantly increase the share of underfloor heating in the total heating of the room. If, for example, the heat loss in a room is reduced to less than 1 W/m3K and the Ecofilm F heating foil is installed over the entire floor area, it will account for more than 65 % of the total room heating. In better insulated buildings, the share of the power input rises to 75 %.

2) An additional heater will be used in the room (e.g. a convector or radiant panel), but only as a supplementary heater during short periods of frost. This heater will ensure that comfort temperature doesn’t fall below the set point during these extremely low outdoor temperatures. As a result, heating with Ecofilm F as a significantly dominant heat source in the room is the fact that the heating foil is able to heat the room on its own without the support of other heaters during the heating season. Moreover, thanks to the large-area heating (thermal comfort at a low heater input) and its precise control (programmable thermostat with floor probe), there is a significant saving in operating costs. This application is particularly suitable for new buildings, but also for complete renovations of buildings where quality insulation is ensured.

B. Laying plan

If the user chooses one of the above options for underfloor heating with Ecofilm F, he should prepare a precise installation plan for the room in advance, which will determine the exact position of the heating foil, the route of the connecting wires and the location of the floor probe.

Important information for the design of the Ecofilm F underfloor heating system:
- Waterproof should be installed under the floor structure to prevent water penetration.
- The thermal insulation under the heating foil is recommended to be laid in two 5 mutually perpendicular layers with overlapping joints.
- Ecofilm F cannot be installed directly on a flammable base. - Heating foil should not be installed directly underneath the fixed equipment
–4cm legs are required to prevent overheating.
- 0'2 mm thick PE foil with 20cm overlaps must be laid on top of the heating foil as protection against moisture
- Ecofilm F is not recommended in rooms with increased humidity (bathrooms, laundry rooms, etc.). When installed in such rooms, a protective grounding plate must be laid on top of the heating film : steel 20 x 20 cm mesh or Al foil with a thickness of 0.2 mm. The grounding plate must be connected to the protective conductor.

Ecofilm C - ceiling heating foils
When heating Ecofilm C works just like the sun. The heating foil emits infrared rays (down to the floor in the case of ceiling heating) which are absorbed by the objects (walls, floor, furniture and the user himself), and only when they hit these objects, they are converted into thermal energy. This modern technology ensures that heat is always efficiently generated where it is most needed. This is one of the great advantages of radiant heating as opposed to convection heating (in convection heating, it is air, that is initially heated by the heater, which only then transfers the heat to the object by sharing it on its surface).

Ecofilm C creates a health-friendly microclimate in the heated rooms. Radiant heating is suitable and recommended for asthmatics and people suffering from respiratory diseases, as it eliminates the unpleasant effects of dry air and dust increase in the heated rooms.

Ecofilm C is suitable for new and renovated building projects. It works well in both small rooms (attics, lofts) as well as in larger units (offices, shops, nurseries, etc.). The heating foil meets all technical and constructional parameters, allowing its application into the plasterboard structures (e.g. smooth temperature rise and even temperature distribution). For these reasons, it is recommended even by the leading manufacturers of such structures.

The Ecofilm MH modular system makes ceiling heating installation super easy.
The latest innovation in the ceiling heating using Ecofilm heating foils is the modular ceiling heating system. The Ecofilm MH system is not only very easy to install, but with the exception of the final wiring, it also has zero requirements for skilled electrical work.

The Ecofilm MH system is not only very easy to install, but with the exception of the final wiring, it also has zero requirements for skilled electrical work.
The 50 × 120 cm heating modules themselves are made up of mineral wool insulation with a thickness of 5 cm. On the thermal insulation Ecofilm C heating foil is glued using a special adhesive. The heating module is fitted with a connecting wire with a plug, the width of the modules corresponds to the axial spacing (50 cm) of the supporting CD profiles of plasterboard ceiling. The heating modules are therefore very simply laid directly on the steel profiles and connected to the backbone wire with sockets. To fill in non-heating areas (e.g. around lights, along walls, etc.), non-heating modules are available which can be trimmed as 6 required.
When compared to the current Ecofilm C heating foil range, the price of the heating modules is significantly higher, however, if we take into account that the modules also include thermal insulation and count the savings on human labour (the installation can also be carried out by workers installing plasterboard construction), the module system can be a very interesting alternative for many countries.
