Is It Safe To Leave An Oil-Filled Radiator On Overnight?
Oil-filled radiators give out gentle, long-lasting warmth, which makes them a favorite for bedrooms and living rooms. It's no surprise that many people ask whether they can leave one running while they sleep.
The Short Answer
Oil-filled radiators are generally considered one of the safer portable heaters because they have no exposed element and the surface doesn't glow. Even so, always follow your manufacturer's instructions, and be aware that fire safety organisations generally advise caution about leaving any portable heater running unattended or while you sleep.
Safety-Features To Look For
- Tip-over protection: Switches the heater off if it's knocked over.
- Overheat protection: Cuts the power if it gets too hot.
- Adjustable thermostat: Stops the heater the heater running flat out all night.
- Timer: Lets you warm the room before bed and switch off automatically.
- Cool-touch handles: Make it safer to move.
Do's and Don'ts For Safe Use
- Do plug it directly into a wall socket rather than an extension lead.
- Do keep it well away from curtains, bedding, furniture and clothes.
- Do place it on a flat, stable floor.
- Don't cover it or dry laundry on it, as this can cause overheating.
- Don't use a damaged cable or plug.
- Don't leave children of pets near it unsupervised.
A Smarter Way To Warm A Bedroom
Rather than running a heater all night, use the timer or thermostat to warm the room before you go to bed, then let the heat fade as you sleep. Warm bedding and a draught-free room do much of the rest.
