Sonniger GuardOne Air Curtain (Electric or ambient air)

No. Our air curtain is not designed to heat a room.

Its primary function is to create an air barrier across a doorway to reduce heat loss, prevent draughts, and limit the ingress of cold air, dust, or insects. It improves energy efficiency, but it is not a space heater.

The electric version can slightly warm the airflow passing through the unit, making the entrance area more comfortable. However, it is not designed to raise the overall room temperature or replace a heating system.

If you require dedicated space heating, an over door heater is the correct solution.

If your goal is to actively heat the room, you should select an over door heater rather than an air curtain.

An over door heater is specifically designed to deliver high heat output into a space. An air curtain’s job is airflow separation and energy retention, not primary heating.
