The Lasko 5572 (29-inch oscillating ceramic tower, fast warmup) and De'Longhi Dragon Digital (silent oil-filled radiator, heat retention) represent two different heating approaches. This comparison covers speed, noise, price, and who should buy each.
Lasko 5572 Oscillating Ceramic Tower Heater
- ✓29-inch oscillating tower
- ✓1500W ceramic element
- ✓Logic Center digital remote
- ✓Adjustable thermostat
- ✓2 heat settings plus fan-only
Pros
- Reaches a comfortable temperature in 5 to 10 minutes, far faster than the radiator
- Oscillation covers a wider area than the stationary De'Longhi
- Costs roughly $50 less than the De'Longhi Dragon Digital
- Includes a digital remote, unlike most heaters at this price
Cons
- No heat retention after shutoff, the room cools quickly once it's off
- Fan noise is more noticeable than the De'Longhi's silent operation
- Only 2 fixed heat settings versus the De'Longhi's 3 with ECO mode
Best for fast warmup and wider coverage at a significantly lower price.
De'Longhi Dragon Digital Oil-Filled Radiator TRD40615EBK
- ✓1500W oil-filled radiator
- ✓75% more radiant surface area design
- ✓Digital display with programmable timer
- ✓ECO energy-saving mode
- ✓3 heat settings
Pros
- Completely silent, fanless operation
- Retains warmth for a while after shutoff, unlike the Lasko
- No fan intake to pull in dust or pet hair
- ECO mode helps manage running cost over long sessions
Cons
- Takes 20 to 30 minutes to warm a room from cold, far slower than the Lasko
- Costs roughly $50 more than the Lasko 5572
- Bulkier and heavier, harder to reposition
Best for silent, steady heat in a room you occupy for hours, at a higher price and slower warmup.
A ceramic tower and an oil-filled radiator both plug into the same outlet and draw the same 1500W, but they heat a room in almost opposite ways.
The Lasko 5572 and De'Longhi Dragon Digital are commonly cross-shopped by buyers deciding between fast, fan-driven heat and slower, silent radiant heat.
The Lasko 5572 uses a 29-inch oscillating ceramic tower to warm a room within 5 to 10 minutes, backed by a digital remote and a price around $45.
The De'Longhi Dragon Digital instead heats a sealed oil reservoir inside metal fins, taking 20 to 30 minutes to reach the same comfort level, but running completely silent and retaining warmth well after shutoff, at a price closer to $95.
Fast and affordable versus slow and silent is the core tradeoff, and the right choice depends heavily on how and when you'll use the heater.
The Short Answer
Buy the Lasko 5572 if you want fast warmup, wider oscillating coverage, and a lower price, and fan noise isn't a dealbreaker.
Buy the De'Longhi Dragon Digital if you want silent operation, heat that lingers after shutoff, and you're willing to pay roughly $50 more and wait longer to warm up.
Spec Comparison
| Spec | Lasko 5572 | De'Longhi Dragon Digital |
|---|---|---|
| Heating method | Ceramic fan-driven | Oil-filled radiator, fanless |
| Warmup time | 5 to 10 minutes | 20 to 30 minutes |
| Noise | Audible fan hum on high | Silent |
| Heat retention after shutoff | Minimal | Noticeable |
| Heat settings | 2 plus fan-only | 3 plus ECO mode |
| Typical price | ~$45 | ~$95 |
Where They Match
Safety features: both include overheat protection, and both are reasonably stable and hard to tip over during normal use.
Oscillation-equivalent coverage: the Lasko's 29-inch oscillating design and the De'Longhi's larger radiant surface area both aim to spread heat across more of a room than a compact unit would.
Where the Lasko Wins
Speed: a clear, measurable difference in how quickly each heater raises room temperature from a cold start.
Price: roughly $50 cheaper, a meaningful gap for a budget-conscious buyer.
Remote control: the Lasko includes one, the De'Longhi controls are all at the unit.
Where the De'Longhi Wins
Noise: completely silent versus an audible fan hum, a real difference for a bedroom or quiet workspace.
Heat retention: the De'Longhi keeps a room warmer for longer after it shuts off, which the fan-driven Lasko cannot replicate.
Dust and allergens: no fan means no intake pulling dust, sawdust, or pet hair through the unit.
Who Should Buy Each
Lasko 5572: garages, living rooms, and any space where fast warmup and a lower price matter more than silence.
De'Longhi Dragon Digital: bedrooms and overnight use, where silent operation and lingering warmth are worth the higher price and slower warmup.
