Where heat escapes from an apartment – a practical guide

Even when heating is on, an apartment may still feel cold. In most cases, the issue is not heating power but heat loss through specific areas. This guide explains where heat escapes, how to check it yourself, and when thermal inspection is the best solution.

Walls and corners – primary loss zones
External walls and corners lose heat first. A simple test is touching the surface – if it feels cold in a warm room, heat is not being stored in the structure.
Overheating the air does not solve the problem – comfort comes from warming the surfaces.

Windows – hidden drafts
Even modern windows can leak heat. A common reason is incorrect pressure settings.
Window cams usually have two modes:
– summer mode – lighter pressure
– winter mode – tighter sealing
Switching to winter mode often significantly reduces heat loss.

Cold floors – inefficient heating sign
If your feet feel cold while the air above is warm, heat distribution is uneven. Increasing temperature only raises costs without improving comfort.

Air – the fastest loss factor
Warm air rises quickly and escapes through weak points. If walls and floors remain cold, energy is wasted heating air volume only.

Thermal inspection – precise results
Manual checks give a general idea, but thermal imaging shows the exact locations of heat loss – windows, joints, corners, walls, and floors.

This is not an issue, of course, if you use UDEN-S heating – our heaters warm the surrounding space evenly instead of chaotically circulating hot air. But you already know that 😎

Conclusion
True comfort starts not with higher temperatures, but with understanding where heat is lost and how to retain it efficiently.
