Over 1000 Airis stove guard units are installed at the Universities of Surrey and Leicester. With their cooperation, we were able to retrieve data collected over a period of several months from around 20 kitchens at each university, with a mix of ceramic and metal plate type cookers/hobs each university. The chart illustrates the positive effect of Airis.
The frequency of Airis interventions was consistently around double for metal plate hobs than for other types. This is likely to be down to the slow response time in heating and cooling which is characteristic of this type of stove.
In some kitchens, Airis intervened in as many as 13% of cooking sessions. It is important to note that while Airis will not interrupt normal safe cooking, it can often detect when a pan has boiled dry or food has started to burn. Airis, therefore, intervenes to prevent a kitchen filling with smoke and prevents damage to hobs and pans, well before a dangerous situation develops.
