De'Longhi Dragon 4 Oil-Filled Radiator: the full buy-or-skip review

Is the De'Longhi Dragon 4 Oil-Filled Radiator worth buying? Short answer: buy it, if you want silent heat for a bedroom. This review explains what this De'Longhi model gets right, where it falls short, what it usually costs in the US and which space heater to buy instead if it is not the right fit for you.

What the De'Longhi Dragon 4 Oil-Filled Radiator does well

The headline: silent radiant heat for bedrooms. Key specs: Power: 1,500 W; Type: Oil-filled radiator; Thermostat: Yes; Safety: Tip-over, overheat. In our list it is the pick for: silent heat. It usually sells for $129–$169.

Holds heat after it switches off, making it gentle and steady.

The trade-offs

Good: silent, even warmth, safe, thermostat. Not so good: slow to heat, heavy. Read the skip-if line before you order: skip it if you want fast heat.

What to buy instead

Instead, consider the De'Longhi Dragon Digital Oil-Filled Radiator ($179–$229): silent, steady heat with a thermostat and safety features. Better if you want quiet, steady heat for a bedroom or office.

Instead, consider the Vornado VH200 ($69–$89): vortex heater that circulates warm air around the room. Better if you want even heat in a medium room.

Instead, consider the Lasko Ceramic Tower Heater 755320 ($59–$79): oscillating ceramic tower heater with remote. Better if you want quick, cheap heat for a home office.

Before you buy

Safety: tip-over and overheat protection and a cool-touch exterior are essential. Type: oil-filled radiators are quiet and steady; ceramic fan heaters warm quickly. Thermostat: a real thermostat saves energy compared with high/low settings.

US buyer tip

At about 17 cents per kWh, a 1,500 W heater costs roughly 25 cents an hour; heating one room can still be cheaper than heating the whole house.

Prices on Amazon.com move in a pattern. The deepest cuts land on Prime Day in July, Prime Big Deal Days in October and the Black Friday to Cyber Monday week, with smaller drops around Presidents Day, Memorial Day, the Fourth of July and back-to-school. Judge a deal against the usual price we show, never against the crossed-out list price.

Order from Amazon itself or the brand's official storefront so the US manufacturer warranty applies, keep your order confirmation and register the product with the brand. Most items can be returned within 30 days, and holiday purchases often get an extended return window into January.
