Air heater NOZ₂ Biddle
Energy efficient heat source brings comfort to large spaces
Biddle is proud to present the NOZ₂, an air heater that offers optimal, efficient heating to large and high-ceilinged buildings. Achieving substantial energy savings and a comfortable working environment is a dual challenge, which the NOZ₂ accepts in style. Model NOZ₂ meets these requirements by combining its strong points, such as an optimal air distribution, minimal heat loss and fully automatic controls.
Automatic heat where it is needed
NOZ₂ when connected with automatic controls will constantly maintain the set temperature. This is possible as a result of the energy-efficient EC fans which have stepless control. The warm air at ceiling level is automatically and effectively recycled to maintain the constant temperature at floor level.
The NOZ₂ air heater is also available in a gas-fired version. The NOZ₂ Gas contains a built-in gas burner that ensures that the heat is distributed.

Energy-efficient heat source provides comfort in large rooms
Biddle NOZ air heater:
optimal air distribution & minimal heat loss
Conventional ceiling and wall heaters:
large temperature differences & high heat loss
Energy-saving climate control
As a consequence heated air is distributed optimally throughout the room. The NOZ has a large influence area, which means fewer devices may be required. The temperature at the top of the room drops considerably by using the inducing effect of the NOZ . As a result, less heated air escapes outside via the roof and walls, which results in considerable energy savings. Furthermore on average 15% less power is consumed to heat up the room than with conventional heating devices.
Automatic heating where needed When the NOZ is fitted with automatic controls it constantly maintains the set temperature. The new energy efficient (EC) fans have stepless control, which ensures the fan runs at the optimum speed. The NOZ energy efficiency is further enhanced by using the fans to provide destratification so that the warm air at ceiling level is re-used to automatically maintain a comfortable working environment at floor level. All this is achieved without any need for the user to adjust the controls.
Various heat sources
The NOZ can be configured to be suitable for any desired heating source including water heating, ambient, gas and/or ventilation models.
The NOZ air heaters are suitable for rooms from 4 - 16 m (13 - 52 ft) in height such as factories, storage rooms, warehouses, DIY shops and sports halls.
