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. In testing, oscillation noticeably reduced the temperature gradient between the side of the room facing the heater and the opposite side compared to running the same heater in fixed mode.

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. For most buyers willing to spend the extra $30 to $40, the Solaris 317 is the better everyday heater.

Dreo Solaris 317 Space Heater Review: Quiet Heat With a Precise Thermostat

The Dreo Solaris 317 is a 1500W ceramic space heater with 70-degree oscillation, a 34dB brushless DC motor, and a digital thermostat accurate to 1°F. Full review with performance notes.

Most ceramic space heaters share the same 1500W ceiling, so the differences that actually matter come down to how quiet, precise, and evenly they distribute that heat.

The Dreo Solaris 317 stands out on exactly those points, running its brushless DC motor at around 34dB while sweeping 70 degrees of oscillation across a room.

At roughly $80, it costs more than a basic Lasko tower, but the digital thermostat holds within 1°F rather than cycling on a coarse dial, and the housing carries ETL certification along with V0 flame retardant material.

In testing, the fan noise stayed low enough to sit a few feet away during a video call without it picking up on the microphone, a real difference from the noticeably louder hum of budget ceramic towers.

The main tradeoff is price. For $30 to $40 less, a Lasko 5572 delivers oscillation and a remote too, just with a coarser two-setting thermostat and a louder motor.

What You Are Buying

The Dreo Solaris 317 is a 1500W PTC ceramic heater with 70-degree oscillation, typically priced around $80. 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 within 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, where 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 within 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

Price relative to output. The Solaris 317 doesn't produce more heat than a $45 Lasko 5572, since both are capped at 1500W. The premium buys quieter operation and a more precise thermostat, not more warmth.

Build material. 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).
