The Best Time to Install Heating Film

The best time to install heating film is during construction or a major renovation, before the floor covering is laid, because then the installation can be coordinated with the other trades. In an existing home, the autumn before the heating season is the most suitable, typically from the end of September to mid-October; in winter it is only worth starting in justified cases, with more careful organisation.

Heating film is a thin, energy-saving heating solution, most often used as underfloor heating but also installed in walls or ceilings. For it to heat reliably and efficiently in winter, timing matters as well as a good product and professional installation. Below we show when and why to install it, and how to choose the date that best suits your home.

What is heating film, and why do people choose it?

Heating film is a thin electric heating element: the heating layer inside it produces heat through its electrical resistance and warms the surface evenly, and the surface radiates the warmth into the room. It is mostly used as underfloor heating, but it can also be built in as wall and ceiling heating.

Its advantages:

• fast, even heat output;
• energy-saving operation;
• thin construction, so it takes up little space;
• in a renovation it can be installed together with a change of flooring;
• easy to control with a thermostat or a smart home system.

These advantages come into their own when the system is installed professionally at a well-chosen time.

When is it worth installing heating film?

During construction or renovation

In terms of timing, one of the best periods is new construction or a major renovation. The room is still open, and it is easier to change floor coverings or build up new layers. The electrical and installation work can be scheduled together with the other trades, which:

• reduces costs;
• allows more reliable installation;
• disturbs everyday life less.

For underfloor heating, it is advisable to prepare the heating system before the floor covering is laid, so that the cables and the film go in the right place. The installation steps are described in our article how we install heating film.

In autumn, before the heating season

If it is not new construction or a major renovation, the best time is the cooler but not yet cold autumn – usually from the end of September to mid-October. The reasons:

• the installation is finished before the heating season, so the heating works from the first cold days;
• there is no need to rush, which helps avoid installation mistakes;
• after commissioning there is time left to set and fine-tune the thermostats.

In winter the work can be more uncomfortable and costly: it is harder to work in an unheated or partly heated home, and both materials supply and installation may be delayed.

In winter, only in justified cases

We do not recommend installation in the middle of the heating season, but sometimes there is no other way – for example the previous heating has failed, or more comfortable warmth is needed immediately. In that case the work has to be organised even more carefully, with special attention that the cold does not reduce the quality of the installation.

How does timing affect operation and efficiency?

A well-chosen date also serves the long-term reliability and efficiency of the system:

• Installation quality: under suitable conditions there is less chance of insulation or wiring faults that could cause trouble later.
• Energy efficiency: if testing and fine-tuning start in good time after commissioning, the system can get settings that reduce consumption.
• Integrity of the floor covering: if installation happens before the flooring, you avoid the problems of breaking open an existing floor afterwards.
• Comfort: if the heating film is already working before the first cold spell, you can enjoy the warmth undisturbed all winter.

Practical tips for timing

• Plan ahead: match the date to your construction or renovation plans; if several trades work at once, coordinate the workflows. You can read about how planning goes on our on-site survey and consultation page.
• Consider the weather: dry, moderately warm weather is ideal for electrical installation; avoid very cold or rainy days.
• Leave it to a professional: a specialist installer knows the rules of installation and scheduling, which is a condition of a long service life. With us, 4th-generation heating film comes with a 15.5-year warranty when we carry out the installation.
• Allow time for commissioning: after installation, set the system precisely and have any faults fixed before the cold weather. You can find details on control on our thermostat page.

What do you gain from well-timed installation?

Summary

Timing is an important factor in making the heating work reliably, economically and comfortably. The ideal time is the stage of new construction or renovation, or the autumn before the heating season, when the installation can be done calmly and carefully. With well-timed installation you can save costs, avoid unpleasant faults and enjoy even warmth all winter. Commissioning is not just a technical matter but one of foresight – it is worth choosing the date consciously, to suit your home.
