Duct Heaters
How to choose duct heaters
Sub-type match
Pick the sub-type first. Climate control appliances give ducted warmth, household appliances cover compact heater coolers, and home & garden listings hold duct tools.
Power rating
Choose kilowatt tier next. Five kilowatt models are lighter on the supply, ten kilowatt ones push more heat but need thicker cabling.
Control type
Thermostat control appears on larger fan heaters. Decide if automatic cutoff matters, or if a basic switch is enough for your setup.
Voltage
Match voltage to source. Twelve volt units need a separate power supply, while 220V elements link to mains or machine circuits.
Duct extras
If your duct run is long, a noise reducing attenuator may be worth adding. It cuts hum but increases total installation length.
What's good
- Industrial fan heaters with ducting move warm air into large spaces. The 5 kilowatt models suit medium workshops, while 10 kilowatt versions cover bigger areas.
- Thermostat control on the larger fan heaters keeps temperature steady without manual adjustment.
- Compact 12V heater cooler units fit where mains power is absent. Their 40mm footprint works in tight enclosures.
- Mica band heaters use stainless steel elements rated at 220V 150W, giving constant heat for plastic injection machinery.
- Listings also include duct accessories like attenuators or crimpers, so you can match heater and ventilation parts in one place.
Things to watch
- High kilowatt fan heaters are heavy once the 6 metre ducting is attached, and they need a strong electrical supply that not every garage has.
- The 12V thermal units produce little warmth, so they are wrong for heating a room and only suit spot cooling or minor heating.
- Mica band heaters are built for industrial machines, with no housing or guard for domestic use.
- Duct accessories like silencers or crimpers mean extra fitting work, which buyers who only want a heater may find unnecessary.
Care & maintenance
Clean intakes
Wipe dust from the fan heater intake grille during use. This protects airflow through the attached duct.
Check thermostat
Test the thermostat on industrial units before winter. A faulty sensor wastes power and risks overheating.
Inspect ducting
Straighten any kinks in the 6 metre ducting. Restricted bends lower the warm air reach.
Secure elements
For mica band heaters, check the mounting clamp tension. Loose elements can scorch the surrounding machine part.
