Heating films for interior ceiling heating

Heating Films systems for interior ceiling heating are installed in the ceilings of both residential and commercial premises, where they provide even radiant heat without any visible heating elements. They are used in flats, detached houses, offices and commercial premises wherever energy-efficient, unobtrusive and comfortable residential heating is required.

Why choose ECOFILM heating films for ceiling heating?

Uniform radiant heat from the ceiling ensures a high level of thermal comfort without draughts or dust being stirred up.
Installation within the ceiling structure saves space in the interior and does not detract from its appearance.
Low running costs: efficient use of energy thanks to the radiant heating principle, ideal in combination with renewable energy sources.
Rapid response to temperature changes: very rapid heat-up compared to underfloor heating.
Part of a smart home: can be controlled via systems such as Loxone or using the FENIX Control Wi-Fi app.

High proportion of radiant heat

The proportion of radiant heat is 84 per cent for Ceiling heating using ECOFILM foils, and 77 per cent for underfloor heating. Heating systems with a high proportion of radiant heat provide customers with greater thermal comfort, as the heat warms people and surfaces directly, rather than just the air. This makes it possible to achieve a comfortable temperature whilst keeping running costs lower.

Flexibility in arranging furniture within an interior

Unlike underfloor heating, with ceiling heating you do not need to take the positioning of furniture into account – the radiant surface area is always larger in this case. Ceiling heating allows for a more even distribution of heat throughout the room, which increases thermal comfort without significant temperature differences.

Rapid response to heating

Modern new-build properties are highly susceptible to heating from the sun or other external sources. If the heating system does not respond quickly enough, rooms become overheated. In this respect, ceiling heating using ECOFILM C foils has been shown to offer greater flexibility than underfloor heating.

Temperature control via a smart home system

ECOFILM ceiling heating films are the ideal solution for modern buildings with a focus on smart home technology and maximum comfort.

When combined with compatible thermostats and smart home systems, they enable intelligent temperature regulation in individual rooms as well as central control of the entire property, including remote control and automated scenarios. ECOFILM ceiling heating thus fits naturally into the smart home concept, where heating adapts to lifestyle, the running of the home and the optimisation of energy consumption.

Frequently asked questions about heating films for interior ceiling heating

In the case of ECOFILM C ceiling films, the plasterboard is indeed heated intensively. Infrared radiation is emitted by all objects that are warmer than their surroundings. So, when the heating film heats up, it transfers heat to the plasterboard, which in turn heats up and begins to emit energy in the form of infrared radiation.

ECOFILM heating films installed in the ceiling heat the room by emitting infrared radiation downwards. The heat is not transferred by air flow, but by striking the floor, walls and people in the room, where it is converted into heat. This ensures that the heating is even, natural and does not result in warm air accumulating near the ceiling.
Miroslav PETR

Yes. The ECOFILM ceiling heating system works on the same principle as solar radiation – the rays pass through the air and heat solid surfaces. These surfaces then radiate the heat back into the room. The result is a stable, comfortable temperature throughout the room, without a cold floor or significant temperature differences.
