This portable, convection oil-filled heater provides soft, radiant heat so quietly, you won't even know it’'s there. The 4 casters use convection to heat your space with 3 heat settings at 1500, 900, and 600 watts. Oil-filled radiators heat more consistently than other styles of heaters and give off residual heat even after the unit is shut off, so your space cools down gently without a harsh transition from hot to cold. With no exposed heating elements they're a smart choice for families with small children, and the tip-over protection adds an extra layer of safety so you can enjoy a warm home and peace of mind.
