Frequently Asked Questions
Q: What should I do if smoke and odours occur during first-time use?
A short burst of smoke or smell can happen the first time it's used, or after it's sat unused for a while, simply from accumulated dust and dirt burning off. Make sure the room's well ventilated, and run just the fan (circulated air mode) on its own for a short spell.
Q: Can I dry clothes or towels on the Eezy heater?
No - never drape textiles, blankets or towels over or in front of the heater to dry them. Doing so risks serious overheating and is a significant fire risk.
Q: What campsite fuse rating is required for each power level?
Eco mode (900W / 230V / 4A) needs at least a 6A campsite fuse; Max mode (1800W / 230V / 8A) needs at least 10A; Night mode (450W / 230V / 2A) needs at least 4A.
