700W Oil-Filled Radiator Heater

The Optimus H-6003 is a portable electric oil-filled radiator rated at 700 watts. It uses permanently sealed diathermic oil to deliver steady radiant heat for rooms up to 150 square feet. A built-in carrying handle makes it easy to move between spaces. Automatic thermostat control maintains the chosen temperature.

Compatibility check before ordering

Ensure a standard mains socket is available near the intended location. The heater draws 700W, so the circuit must support that load alongside other devices. Confirm the room size does not exceed the 150 sq. ft. rating for effective warming. No installation or plumbing is required.

Suitable for supplemental room heating

This model suits homeowners or renters needing quiet, portable spot heat for bedrooms, offices or small living areas. It is not intended as a primary whole-house heating system. Buyers who want higher output for larger spaces or integrated smart controls should look at other solutions.

Questions about this item

What comes in the box and is anything else needed to run the H-6003?

The heater ships fully assembled with its permanently sealed diathermic oil and built-in carrying handle; just plug it into a standard wall socket and no extra parts are required.

Which capacity should I choose for my room size?

The single 700W model is rated for spaces up to 150 sq. ft., so pick it when the area you want to warm falls within that range.

What does the 700W rating mean once the unit is running in my home?

It delivers a maximum of 700 watts of heat output, and the automatic thermostat cycles the element on and off to maintain the temperature you set with the rotary switch.
