The utility of delayering is often overlooked by building occupants or managers; yet its principle is very simple and allows significant energy savings to be made very quickly.
Principle
When heating a given volume with a fairly high ceiling height (greater than 5 meters), the heat rises and accumulates at the ceiling. Thus it is necessary to heat more to reach the desired temperature setpoint on the floor.
The principle of destratification simply consists in bringing this accumulated heat back down to the ground so that the occupants benefit fully from it without having to overheat.
Destratifiers are equipment that makes it possible to homogenize the temperature throughout the heated volume.

When to use a destratifier?
It is advisable to use an air destratifier when the ceiling height is greater than 5 meters and the heating used is of the volume type. (unit heaters, underfloor heating, rooftop + ducts, CTA + ducts).
Its application will be all the more profitable as the ceiling height is high. It will therefore be a particularly effective solution for gymnasiums, logistics warehouses or even supermarkets heated by unit heaters.
On the other hand, when the heating system is of the surface type (radiant tubes, luminous radiant heaters), the phenomenon of stratification is less since the air does not act as a vector of heat.
Very fast energy savings
The homogenization of the temperature makes it possible to put less stress on the heating production equipment. In addition, a feeling of improved comfort makes it possible to lower the set temperature of the heated zone.
According to ADEME, reducing the set temperature of your installation by 1°C can reduce annual heating consumption by 5 to 10%.
In summary, the benefits of delayering translate into:
– Heating costs reduced by 20% to 50%
– A reduction in CO2 emissions of 20% to 50%
– Significant reduction in heat loss
– A simplicity, speed and efficiency of the solution
– Negligible operating costs
– Rapid returns on investment (less than 3 years)
– Improved working conditions
– Improved customer comfort
– A more comfortable living space
Finally, this system can claim Energy Savings Certificates (EEC) via the BAT-TH-142 and IND-BA-110 sheets provided that a minimum height of 5 meters is respected and that the destratifiers are coupled to thermostats .
