A heat recirculation ceiling fan is an industrial high-efficiency fan installed beneath the ceiling. It directs accumulated warm air back into the occupied zone without creating uncomfortable draughts. Unlike conventional ceiling fans, ThermoReturn uses specialised airflow technology to achieve uniform temperature distribution throughout the room, without modifying the existing heating system.

Destratification refers to the elimination of temperature layers within a space. In buildings with high ceilings, warm air accumulates beneath the roof, where temperatures can be 10 to 15°C higher than in the occupied zone near the floor. Destratification deliberately moves this warm air downwards, creating a more uniform temperature distribution.

Heat recirculation describes the process of actively returning heating energy accumulated beneath the ceiling to occupied and working areas. This can reduce heating energy consumption by making use of existing warm air instead of generating additional heat.

EU ErP 2026 refers to EU Regulation (EU) 2024/1834 on ecodesign requirements for fans under the Energy-related Products framework. It introduces stricter efficiency requirements for industrial fans from July 2026. The ThermoReturn ceiling fan meets these requirements.

In practice, heating cost savings of up to 30% can be achieved. Actual savings depend on several factors, particularly building height, insulation, heating system, ventilation conditions, type of use and weather conditions.

The payback period depends on current energy costs and the savings achieved. In many cases, the investment pays for itself through reduced heating costs within a comparatively short period. ThermoReturn can provide an individual cost-effectiveness calculation upon request.

Thermal imaging measurements and monitoring campaigns using distributed temperature and humidity sensors document the effects. After activating the ThermoReturn ceiling fan, heat can become more evenly distributed, heating system restart times may be delayed and daily heating operating times may decrease. Specific results depend on the building and operating conditions.

Yes. The ThermoReturn ceiling fan is optionally available with a reverse function. This allows switching between heat recirculation in winter and active exhaust airflow in summer. Warm air can be directed outside through existing roof openings.

The ThermoReturn ceiling fan is designed for buildings with high ceilings starting at approximately four metres. Typical applications include production facilities, warehouses, high-bay storage facilities, livestock buildings, greenhouses, wholesale markets, supermarkets and DIY stores.

ThermoReturn offers different performance classes: ThermoReturn small for ceiling heights up to 12 metres, ThermoReturn medium for ceiling heights up to 18 metres and ThermoReturn large for taller spaces.

ThermoReturn reverse is also available. This version can switch between downward heat recirculation in winter and active upward exhaust airflow in summer.

The selection depends on ceiling height, floor area, structural installations, ventilation conditions and the heating system. ThermoReturn assists in selecting and positioning the appropriate performance class.

No. The ThermoReturn ceiling fan operates independently of the existing heating system and can be retrofitted. It complements existing heating technologies, including gas, oil, district heating and heat pumps.

The ThermoReturn ceiling fan can be integrated into existing building management or facility management systems.

For buildings without existing control technology, ThermoReturn offers a standalone energy-saving controller with a PT100 temperature sensor, continuously variable 0–10 V control, manual operation and an optional timer. The controller is protected by an IP64 enclosure.

Thanks to its high-efficiency EC motor and aerodynamically optimised hybrid-structure sickle-shaped blades, the ThermoReturn ceiling fan operates with exceptionally low noise levels, even at higher rotational speeds.

The ceiling fan is designed for demanding environments. Its die-cast aluminium electronics enclosure provides corrosion protection, the Moisture Protection System automatically releases condensation to the outside and its stainless steel suspension eyes meet the specified safety requirements.

Yes. The ThermoReturn ceiling fan is suitable for heated livestock buildings, including pig, calf and poultry housing. It improves temperature distribution from floor to ceiling and can reduce cold zones in resting and feeding areas.

Draughts, cold zones and significant temperature fluctuations are recognised stress factors in livestock farming. They can affect animal health, feed intake and productivity. Maintaining the most uniform possible indoor climate therefore also has economic importance.

Yes. In greenhouses, the ThermoReturn ceiling fan supports more uniform temperature and humidity distribution across the growing area. Natural day-night fluctuations generally remain; the system primarily balances local temperature differences within the space.

When heat recirculation reduces heating energy demand, the building's associated CO₂ emissions may also decrease. The energy savings achieved can be documented and considered in relevant sustainability reports.

Documented energy savings achieved through ThermoReturn can be included in a company's sustainability reporting as an energy efficiency or CO₂ reduction measure. The specific information required depends on the reporting obligations applicable to the individual company.

Yes. According to the manufacturer, the ThermoReturn ceiling fan meets the requirements of EU Regulation (EU) 2024/1834 under the ErP requirements applicable to fans from 2026.
