DREO Oil-filled Radiator 310 review

The DREO Oil-filled Radiator 310 is a floor-standing radiator with touch controls and a remote, rather than a small ceramic heater that blows a directed stream of air. DREO’s U.S. page calls the retail configuration OH310; the matching U.S. user manual labels the electrical model DR-HSH010. The native U.S. listing groups Gray SKU 10-04010-181 and Black SKU 10-04010-101 as colors of the same product. I reviewed those variant links, the U.S. product page and the DR-HSH010 U.S. manual; I have not measured warming speed, noise, efficiency, or coverage in a room.

A digital radiator with a useful countdown

The manual lists H1/H2/H3 output at 600, 900 and 1,500 W, plus ECO mode. ECO uses a set temperature instead of leaving you to choose one fixed wattage step. The DREO page lists 41–95°F in one-degree increments; a remote is included and takes a CR2025 battery. The touch panel also provides mute, child-lock and display controls. Child lock is on the heater panel, not the remote, so consider that before treating the remote as the only control.

Its timer is more flexible than the simple thermostat on the Radiator 153: the DR-HSH010 manual describes a 0–24-hour countdown that switches off a running heater or starts one that is off. The current product page lists the timer as 1–24 hours. In practical terms, the sourced instructions support a one-time countdown, not a weekly schedule, a named clock time, or phone-app automation. If automatic start is essential, the 310 is a documented option; if a timer is irrelevant and an ordinary mechanical knob is easier for your household, the 153 remains the simpler alternative.

Check the body dimensions instead of guessing from photos

DREO lists the 310 at 12.2 × 9.84 × 26.06 inches. It also describes seven fins, a digital display, easy mobility and a remote. The model is shorter on the manufacturer’s listed dimensions than the 521, whose last listed dimension is 28.54 inches, but their other listed measurements run in different directions. Compare the full dimensions and caster footprint with your available spot rather than assuming one is smaller on every side. The manufacturer page does not publish a weight in its specification list, so I do not use weight to rank it against the 521 or 153.

Both the 310 and 521 have the same listed maximum of 1,500 W and the same three wattage steps. A seven-fin layout, digital thermostat or “whole-home warmth” headline should not be read as a tested room-size guarantee. There are no independent heating-rate or cost measurements here. The 310’s oil-filled radiator form also does not provide a separate fan-only mode, powered oscillation, or phone app that the reviewed page and manual establish. If air movement without heat, rapid directed airflow, or explicit wall mounting is a requirement, look at a different product type.

Use the U.S. manual, not a similar export document

The DR-HSH010 manual reviewed for this U.S. 310 states 1500 W, 120 V~60 Hz and a CR2025 remote battery. A matching model code also appears on non-U.S. radiator documentation with a different voltage rating, so a user should follow the rating plate and U.S. instructions for the actual unit rather than substitute a similarly named export manual. The product is a high-power appliance: plug it directly into a suitable wall receptacle, never an extension lead or power strip, and avoid stacking it with other high-load appliances on the same outlet/circuit.

The manual restricts this heater to household indoor use and says not to use it outdoors, in bathrooms, laundry rooms or similar places. Place it upright on a stable, level floor after installing the casters. Keep combustible materials at least three feet from the front and away from the sides and rear; the sides and rear may be very hot. Do not cover it, block its openings or put it on a soft surface. First use calls for a two-hour high-power run in a ventilated room. For care, unplug it, let it cool and wipe with a soft dry cloth. Tip-over and overheat protection do not replace those precautions.

Who is the 310 for?

The 310 is worth comparing if you want a fanless radiator arrangement with a remote, temperature setting, multiple power levels and a countdown timer that can start or stop it, while a 26.06-inch listed body suits the available floor space. It is not a fit for a strict body cap below 26.06 inches, required bathroom use, outdoor heating, mobile app scheduling or fan-only airflow. Choose between it and the 521 based on measured placement dimensions and the finish you prefer, not on unverified claims about which will warm a room faster. The 153 is the simpler knob-controlled comparison; a documented ceramic fan heater is the better direction if moving air without heat is non-negotiable.
