When a larger room struggles to hold onto warmth, you need more than a short burst of heat. The Vonhaus 11 fin oil filled radiator gives bigger spaces steady, adjustable comfort, with higher heat output, a 24-hour timer and safety features built into the design.With 1000W, 1500W and 2500W heat settings, this grey oil filled heater is designed for rooms up to 30m². Use it to warm a living room, bedroom, dining area or home office, then set the timer around the parts of the day when you want heat ready and waiting.More power for larger roomsBigger rooms need more heating capacity, especially when ceilings are high, doors are open or the space takes longer to warm through.This 11 fin oil filled radiator offers three output levels: 1000W, 1500W and 2500W. Start lower when you only need background warmth, or choose the full 2500W setting when the room needs more heat behind it.For help choosing the right output for your space, see our guide to choosing the right heater for your room size.Schedule warmth around your dayNobody wants to walk into a cold room and wait for comfort to catch up. The 24-hour timer gives you more control over when the radiator runs, helping you plan heat around your routine.Set it to come on before you sit down for the evening, warm the home office before work, or switch off after a set period. Used sensibly, the timer helps you focus heat around the hours you need it most, rather than leaving the radiator running longer than necessary.Steady heat from an 11 fin designOil filled radiators are built for consistent warmth. Rather than blowing hot air around the room, they heat the oil inside the unit and release warmth steadily from the fins.This model uses an 11 fin design with five oil channels and an enhanced surface area to help spread heat effectively. It is a strong choice for living rooms, larger bedrooms and everyday spaces where you want warmth to feel settled rather than sudden.Browse more models in our oil filled radiators collection.Adjust the heat, then let it settleUse the thermostat dial to find your preferred level of warmth, then choose between the 1000W, 1500W and 2500W power settings depending on the room. Once the set level is reached, the advanced thermal sensor helps the radiator cycle on and off to maintain a more consistent temperature.That makes it easier to keep a larger space comfortable through longer evenings, work sessions or slower winter mornings.Portable comfort, room by roomFour 360° wheels and a carry handle help you move the radiator between suitable rooms, while the cable tidy keeps the 1.5m cable controlled when the unit is stored away. Use it in the lounge one night and the home office the next, without needing a permanent heating setup in every space.Explore more portable heating options in the wider Vonhaus heating range, or compare heater types in our guide to oil filled radiators vs electric heaters.Safety features for added reassuranceThis electric radiator includes automatic overheat protection and a 45° tip-over switch, designed to shut the heater off if it becomes too hot or is knocked beyond the stated angle.
