- How long does it take to heat a room?
- Oil-filled radiators warm up gradually, typically over 15 to 30 minutes before the room feels noticeably warmer. After that the thermostat cycles the element to hold the temperature.
- Is it safe to leave on overnight?
- It has a thermostat and automatic shut-off, and oil-filled models are generally considered safe for long runs. Keep it clear of curtains and furniture and do not cover the fins.
- Can it heat a large room on its own?
- At 2.5kW it is one of the more powerful portable electric heaters, so it can carry a large room or open-plan area. In a very cold or poorly insulated space it works best as a supplement.
- Does it make any noise?
- No. There is no fan, so the only sound is occasional ticking as the metal and oil expand and contract.
- Can I plug it into a normal socket?
- It runs on mains power, but at full output it draws close to the limit of a standard UK socket. Avoid extension leads and avoid sharing the circuit with other high-power appliances.
- Does it need oil refilling?
- No. The oil is sealed inside the fins for the life of the unit and does not need topping up.
