Oil-filled electric heater Ravanson OH-11 2500W, 11 tubes, portable, grey

The Ravanson OH-11 2500W electric heater is an oil-filled radiator designed for indoor heating. Finished in white and silver, it combines a compact footprint with a conventional radiator appearance to provide steady, even warmth. The unit operates at a rated power of 2500 W and is intended to maintain comfortable room temperatures during cold periods by using oil as a heat reservoir that releases warmth gradually.

Advantages

The oil-filled design delivers uniform heat distribution and retains warmth after the element cycles off, reducing temperature fluctuations. Its rated 2500 W power enables faster temperature recovery in medium to larger rooms compared with lower-power models. The white and silver housing is easy to integrate into home interiors and the enclosed heating elements minimize direct contact, offering a safer surface temperature profile than some exposed-element heaters.

Suitable for

• Heating living rooms and bedrooms
• Maintaining steady background heating in open-plan apartments
• Supplementing central heating in colder zones of a house
• Temporary heating in home offices or hobby rooms

Key specifications

• Power output: 2500 W
• Type: oil-filled radiator (indoor use)
• Color: white and silver finish
• Heating method: convective and radiant heat from oil-filled fins
• Control: built-in thermostat and power settings (multiple heat levels)
• Mobility: caster wheels and integrated handle for repositioning
• Safety features: overheat protection and tip-over safety cut-out

How to use

Position the heater on a flat, stable surface at least 30 cm away from furniture, curtains and other combustible materials. Plug the unit into a suitable indoor power outlet and select the desired power level using the control dial or switches. Allow the radiator to warm up; the oil inside will store heat and provide a gradual, sustained output. Use the built-in thermostat to maintain a comfortable room temperature and switch the heater off when not required. For mobility, tilt slightly and roll the unit on its casters, using the integrated handle.

Usage recommendations

For efficient operation, preheat the room on a medium setting and then reduce to a lower setting once the desired temperature is reached to save energy. Do not cover the heater or place objects on top. Regularly check the power cable for damage and ensure adequate ventilation around the unit. Follow local safety guidelines for indoor electric heating devices.
