Best oil-filled radiator space heaters
Researched by Deal.ai's shopping agent across stores on November 11, 2026. Prices below are today's.
Top pick: De'Longhi EW7707CM 1500W oil-filled radiator. De'Longhi is the name that's been making these longest, and this one is a true 1500W radiator with three heat settings and an adjustable thermostat — the straightforward, quiet, no-frills choice for a bedroom or living room.
Who the others suit:
- Costway 1500W (Lowe's) — best if you want a light, easy-to-move unit with 600/900/1500W steps.
- Costway 5.7-fin (Walmart) — a solid budget radiator with a big review base.
- Taoset / CONCETTA — cheapest way in if the room is small and you just need steady background heat.
- Romswi — if you want a remote, digital thermostat and a 24-hour timer.
Skip the DREO "Oil-filled Radiator 153" and Mainstays if you specifically need 1500W: their listings don't confirm it. Oil-filled radiators heat slowly but stay warm after switching off, and they're silent — good for bedrooms.
