A poorly heated warehouse can consume up to 150 kWh per square meter per year. An optimized installation reduces this to 40-60 kWh/m²/year. On a 10,000 m² logistics platform, the difference amounts to tens of thousands of euros each winter. Before choosing equipment, it is better to understand exactly where this energy is being used. But also why warehouses with heavy truck traffic do not heat up like a closed workshop. ClimnTech, a specialist in remote infrared heating, helps you understand everything.
The true cost of heat lost in a logistics platform
Ceiling height and stratification of the warm air
A height of 8 to 15 meters, common on logistics platforms, promotes the accumulation of warm air in the roof. Without destratification, several degrees of difference separate the ceiling from the level where the operators actually work, which drives conventional heating systems to produce more to compensate for this structural loss.
Insulation designed for storage, not for thermal comfort
Many logistics buildings have been designed to optimize storage volumes, not to retain heat. Metal roofing, poorly insulated roofs, large glazed surfaces on the office side? Every aspect of the envelope is a direct result of overconsumption. And this applies regardless of the heating system installed behind it.
The dock doors, the most underrated loss position
This is the least documented factor in the general technical literature, yet it has a significant impact on the energy balance of high-traffic platforms. Indeed, every opening of a dock door lets some of the heated air escape, several dozen times a day in an active site.
Why loading docks contribute to the energy bill
Aerothermal and destratification: effective, but not everywhere
This combination remains relevant for heating a closed volume homogeneously. But in an area of the deck where the doors open continuously, the logic reverses. Here, the hot air produced escapes partially before the atmosphere has even stabilized. This greatly degrades the actual performance of the installation.
Infrared radiation, a response that ignores air currents
It is precisely in this configuration that the Industrial far-infrared heating It changes the game. By heating the operators and surfaces directly, rather than the ambient air, it maintains its effectiveness even when a door remains open. In fact, the radiation reaches its target regardless of the air’s stability.
Does your platform accumulate dock openings and thermal losses? Let's talk about it with an expert from ClimnTech to identify the areas to be treated as a matter of priority.
Import-export and refrigeration platforms: separate heating needs
Buffer zones between negative and outdoor temperatures
On a cold storage platform, operators spend several dozen times a day moving from a negative environment directed towards an exterior that is often just as cool in winter. And this without ever benefiting from a real intermediate warming time. Heating all these buffer zones makes no economic sense.
Maintaining the gel-free state rather than classic thermal comfort
The objective is not always to achieve a comfortable temperature. But rather to protect the water networks and equipment sensitive to freezing. Targeted heating at fixed locations (docking stations, control points, driver waiting areas) meets this need. And this without wasting energy on volumes that are not intended to be continuously heated.
Heat the area, not the volume: the economic reasoning
Mapping the areas according to their actual use
Good sizing always starts with precise mapping. Which areas are continuously occupied? Which ones are only occupied occasionally? Which areas are frequently crossed by openings? This diagnosis avoids over-equipment through excessive caution.
Combining several technologies rather than a single solution
On a platform with multiple zone profiles (closed storage, open dock, offices), the right approach generally involves several complementary technologies rather than a single solution applied to the entire building.
Calculating the return on investment of your warehouse heating system
The return on investment is calculated by comparing two data sets. First, the current cost of heat lost in high-traffic areas. Then, the savings generated by a system that only heats the workstations that are actually occupied.
Thus, in warehouses where the heating season extends over several months and where the docks are continuously in use, the gap quickly widens in favor of a targeted solution. ClimnTech accompanies the operators of logistics and cold storage platforms in this diagnosis. With the expertise presented on the page About from the company.

Reducing the heating bill of a logistics warehouse does not necessarily involve replacing the existing installation completely. The first useful step remains to map out the areas that are actually traversed by frequent openings, and then to check whether the energy spent in these areas corresponds to a real need for comfort or to a mere habit inherited from the past.
Frequently Asked Questions
Why do dock doors increase the heating bill so much?
Each opening lets some of the heated air escape, which forces a hot-air system to continuously produce air to compensate for repeated loss, rather than maintaining a stable temperature.
Does the remote infrared heating work even with the door open?
Yes, since it directly heats people and surfaces through radiation, without depending on the stability of the ambient air. This is a specific advantage in areas with frequent openings.
Should the entire warehouse be heated at the same temperature?
No, in the majority of cases. A zone-based approach, adapted to the actual use of each space (storage, dock, offices), allows for substantial savings compared to uniform heating of the entire volume.
What is the difference in requirements between a traditional warehouse and a cold storage facility?
A refrigeration platform must manage buffer zones between negative temperatures and the outside environment, often with the goal of maintaining frost-free conditions rather than conventional thermal comfort, which completely changes the sizing of the heating system.
