Space-saving oil-filled radiator

The Optimus H-6003 is a compact oil-filled radiator designed to heat areas up to 150 square feet. Its 700 W output suits bedrooms, home offices or small workspaces where a full-size heater would be excessive. The permanently sealed diathermic oil distributes warmth evenly without requiring refills. A built-in carry handle lets you move the unit between rooms as needed.

Upgrade from personal fan heaters

This model replaces small fan-forced heaters that blow dust and dry the air while struggling to maintain steady temperatures. The oil-filled design eliminates moving parts and operates silently, making the switch worthwhile for anyone who needs consistent background heat during long work or sleep periods. Overheat protection adds a safety layer that basic personal heaters often lack.

Steady output during extended use

Under continuous operation the diathermic oil acts as a thermal reservoir, smoothing temperature swings that occur with element-only heaters. The rotary thermostat maintains the chosen setting without frequent cycling, and the heavy-gauge metal cabinet resists denting during daily repositioning. Surface temperatures stay manageable for a compact heater running hour after hour.

Questions about this item

How much floor space does the 16.00" by 15.00" heater need?

The unit measures 16.00 inches tall, 15.00 inches long and 6.00 inches wide, so allow at least that footprint plus a few inches of clearance around all sides.

What is the first step when setting up the H-6003, and what mistake should I avoid?

Place the heater on a flat, level surface, plug it into a grounded outlet, then turn the rotary thermostat to the desired setting; do not use an extension lead or power strip.

Will the permanently sealed diathermic oil ever need topping up or replacing?

No, the oil is permanently sealed inside the radiator and does not require refilling or replacement for the life of the heater.
