FEZ overhead radiant heaters - approvals

The FEZ range of electric radiant overhead heaters have been tested for conformity and compliance with the EC Electromagnetic Compatibility (EMC) Directive 89/336 /EEC & 92/31 EEC EC Low Voltage Directive (LVD) 73/23/EEC, and are CE marked.

Electricity supply requirements for FEZ infrared radiant heaters

Activair electric heaters are designed for European and UK 50Hz supplies, and are suitable for use in the UK, most of Europe, Eastern Europe and the Middle East.

The FEZ21, 217 and 222 require a 230V single phase electricity supply.

The FEZ336 requires a 400V 3 phase and neutral supply.

Radiant heater controls

Our overhead radiant heaters are very economical to run, however running costs can be reduced further by energy saving controls:-

Heater controls
HVR1 - manual output controller Manual output control (HVR1) Maximum load 3kw 230V
Not suitable for FEZ336
quote
HTIM - One touch timer for infra-red heaters Manual timer (HTIM) Maximum load 4.5kw 230V
Not suitable for FEZ336
quote

Energy saving controls must only be installed by a suitably qualified person in accordance with local wiring regulations.

Because our overhead heaters take approximately 25 minutes to heat up, we do not recommend the use of movement detectors (PIR's).

FEZ electric infrared radiant heaters - 1 year guarantee

Activair FEZ infrared radiant heaters are manufactured to the highest standards, and we are confident that they are completely reliable. However, in the unlikely event a fault may occur, they have a 1 year return to base parts and labour guarantee.
