De'Longhi Dragon 4 Oil-Filled Radiator vs Costway 1500W Oil Filled Radiator Heater

The Costway is the more convenient heater for most US shoppers: 120V plug, remote control, precise 1°F thermostat and a 24-hour timer. The De'Longhi Dragon 4 is the sturdier long-term buy, with 8 fins, a 10-year guarantee and a simpler mechanical build that has fewer parts to fail. Reviewers of oil radiators in this class praise quiet, steady heat from both; the Costway's remote and digital controls are the practical edge, while the De'Longhi's warranty and build are the durability edge.

  • Choose the De'Longhi Dragon 4 if you want a low-maintenance heater with a long guarantee and a mechanical dial you can set and forget.
  • Choose the Costway if you want remote control, a precise thermostat and a timer, and you have standard US 120V outlets.

What reviewers say

De'Longhi Dragon 4 Oil-Filled Radiator

Owners of the Dragon 4 series generally rate the quiet, steady heat and the long guarantee highly, and many keep them for years. Complaints tend to focus on slow warm-up, weight and the hot metal body rather than reliability.

What people mention
  • NoisePraisedOwners say it runs silently, which makes it a favorite for bedrooms and night use.
  • Heat-up timeCriticisedReviewers note it warms a cold room slowly compared with fan heaters.
  • Build qualityPraisedBuyers describe it as solidly built and backed by a long guarantee.
  • PortabilityMixedCastors help on flat floors, but owners find it heavy to lift and carry.

Questions and answers

Which heats a room faster?
Both are oil-filled, so they warm up slowly and radiate steadily. The De'Longhi's 8 fins give it more surface area, but the Costway's 1500W setting is comparable in output. Neither is fast like a fan heater.
Can I use the De'Longhi in the US?
Only with a step-up transformer, because it is rated 220–240V. The Costway is 120V and plugs into a normal US outlet, which makes it the simpler choice here.
Which is better for a bedroom?
The Costway, thanks to its remote, 1°F thermostat and screen-off mode. The De'Longhi is equally silent but its mechanical timer ticks and it has no remote.
Which lasts longer?
The De'Longhi has the longer guarantee at 10 years and fewer electronic parts to fail. The Costway's digital controls and remote add convenience but more failure points.
Is the Costway safe around kids and pets?
It has 45° tip-over protection, overheat protection and flame-retardant materials, and is ETL listed. The De'Longhi lists standard thermal protection but no tip-over switch.
