Yes, however we recommend that the units be left to run 24/7 throughout the heating season.
This is because as soon as the system is turned off, the warm air is allowed to rise again and by letting the temperature at ceiling level increase by any amount increases your buildings heat loss significantly.
Also, as the Airius units send the air down to ground level, which then blankets across the floor at 4 to 6 inches high. The floor gradually starts to heat up and becomes a thermal battery. The heat stored in the floor is then slowly released whenever the heating is not running.
This has been a tough message to get across as people tend not to want to leave an electric motor running, especially not overnight if the building is not occupied.
To prove the benefits we conducted a study at a pharmaceutical storage facility (Chemilines), where they were strongly against leaving the units running overnight. The company was losing between 10 and 12°C during a typical winter’s night when the heating and Airius units were switched off.
As a result, the company had to turn on their heating for 2.5 to 3 hours before the staff arrived to ensure the temperature was at a comfortable level.
The company then conducted the same test with the Airius units running. With their heating system turning off at the same time they found that instead of losing 10 to 12°C, they were only losing 2.5 to 3°C! This reduced their morning pre heat time from 2.5 to 3 hours to 30 to 45 minutes. The reduced heat up time alone amounted to a 20% saving.
We only recommend turning the units off if your building is going to be unheated for a period of more than 24 hours.
