Dreo Solaris 317 Space Heater
70-degree oscillation spreads warmth across a two-bay garage workspace
View on AmazonPros
- 70-degree oscillation spreads heat across a noticeably wider arc than fixed heaters
- 34dB fan noise is quiet enough to run in an occupied living room without being distracting
- 1°F thermostat steps hold a target temperature more precisely than dial-based competitors
- Digital display and remote make adjusting settings from across a large room easy
Cons
- Still capped at 1500W like every other model here, so raw output is the same
- Plastic housing feels lighter-duty than the De'Longhi's metal radiator body
- Priced higher than basic tower heaters without oscillation
Our verdict
The Dreo Solaris 317 Space Heater in brief. Who it's for: the Dreo Solaris 317 is right if: you want the quietest ceramic heater available at this price, you value a precise thermostat over a basic dial, and they're wil. What it does best: 70-degree oscillation spreads warmth across a two-bay garage workspace; eTL-certified safety protections matter around tools and stored materials. Ma in drawback: fan intake needs occasional cleaning in a dusty garage.
What You Are Buying
It uses a brushless DC motor, which Dreo rates at approximately 34dB, quieter than the standard AC motors found in most tower heaters at this price point.
The digital thermostat runs from 41°F to 95°F in 1°F increments, controlled either at the unit or via the included remote.
A 12-hour timer lets it shut off automatically overnight or after you leave a room.
Performance
Warmup time: From a cold start in a 65°F room, the Solaris 317 raised the immediate area to a noticeably warmer temperature with in 5 to 8 minutes, in line with other 1500W PTC ceramic heaters.
Oscillation coverage: Running the 70-degree sweep in a roughly 250 square foot room produced a more even temperature across the room compared to running the same unit in fixed mode, w here one side of the room stayed noticeably cooler.
Noise: Measured informally at roughly 3 feet, the fan noise was subtle enough to fade into the background with in a few minutes, a clear step down from the more noticeable hum of basic ceramic towers on their high setting.
Thermostat accuracy: Set to 72°F, the unit cycled the element on and off in a tight band, avoiding the wider temperature swings common with simple high/low dial heaters.
What It Does Well
The 34dB motor is the standout feature.
It's quiet enough to leave running during work calls or while reading, which is not true of most heaters in this price range.
The 1°F thermostat increments give real control over room temperature rather than the blunt high/medium/low choices found on cheaper units.
Safety certifications are more thorough than typical for this price point: ETL certification alongside V0 flame retardant housing material, on top of the standard tip-over and overheat protection.
What Falls Short
The premium buys quieter operation and a more precise thermostat, not more warmth.
The housing is plastic, and while it feels solid enough for daily use, it doesn't have the heft of a metal-bodied oil-filled radiator like the De'Longhi Dragon Digital.
Who Should Buy It
The Dreo Solaris 317 is right if: you want the quietest ceramic heater available at this price, you value a precise thermostat over a basic dial, and you're willing to pay a premium for those upgrades.
Consider alternatives if: you're on a tight budget (Lasko 5572 or Lasko 754200), you want fanless silent heat retention (De'Longhi Dragon Digital), or you only need to heat a desk zone (Vornado VH202).

Common questions
How quiet is the Dreo Solaris 317 in practice?
Dreo rates the brushless DC motor at approximately 34dB, and in practice it's quiet enough to sit a few feet away during a video call without being picked up by a laptop microphone. It's noticeably quieter than basic ceramic tower heaters, which typically run in the 45 to 50dB range on their high setting.
Does the Dreo Solaris 317 actually reach 95°F room temperature?
95°F is the maximum thermostat setting, not a guarantee for the whole room. In a typical bedroom, setting the thermostat to 95°F will keep the immediate area near the heater quite warm, but the room's actual ambient temperature will land lower depending on insulation, room size, and how well-sealed the space is.
Is the 70-degree oscillation on the Dreo Solaris worth it?
Yes, for anything larger than a small bedroom.
How does the Dreo Solaris 317 compare to a basic Lasko tower heater?
The Solaris 317 is quieter, has a more precise thermostat, and includes a remote and digital display, all advantages over a basic Lasko like the 5572. The Lasko costs meaningfully less and has been on the market longer, giving it a larger ratings history.
