Same 1500 Watts product guide
Dreo Atom One DR-HSH004 1500W Ceramic Space Heater
A desk or bedside spot within cord reach of a wall outlet, with three feet clear in front
A small PTC fan heater whose manual names all three heat levels (1000, 1300 and 1500 watts) and an ECO thermostat you set between 41 and 95 degrees Fahrenheit. Tip-over and overheat cut-offs show as P4 and FF on the display. The same manual bans extension cords and power strips, keeps it out of bathrooms, and wants three feet of clear space in front.

Fit and limits
Strengths
- The maker's manual names each heat level in watts and a 41-95 F thermostat, so you can predict the draw
- Tip-over and overheat shut-offs are documented with their display codes, P4 and FF
- Rinse-and-dry pull-out dust filter, remote, 0-12 hour timer and memory of the last settings
Caveats
- The manual forbids extension cords and power strips, so it has to reach a wall outlet itself
- Not for bathrooms or laundry areas, and three feet must stay clear in front of it
- The 24-hour auto-off is off until you enable it, and the listing's 37.5 dB and 34 dB noise claims disagree
A small PTC fan heater with a real thermostat, not a dial
Amazon sells this as the Dreo Atom One. The details table gives the model as DR-HSH004 and the part number as DR-HSH004-G, and Dreo's own support page confirms that the Atom One 'Standard' covers DR-HSH004, DR-HSH004-G, DR-HSH004A and DR-HSH004B. The manual Dreo links for the US market is titled DR-HSH004-G, so the document and the part number on the listing match.
The manual's specification table is short: model DR-HSH004-G, rated power 1500 W, input 120V~60Hz, and a CR2025 3V coin cell for the remote. The package contents drawing shows the heater, a pull-out dust filter, a user manual, a quick start guide and the remote. There is no separate stand or wall bracket.
This is a ceramic (PTC) fan heater, so it blows warm air rather than radiating heat from an oil-filled body. The manual labels the front as a hot surface and says not to touch it while the heater is running.
Three named wattages, plus an ECO mode that sets a temperature
The manual is unusually specific about power. Power Heat mode has three levels: H1 at 1000 W, H2 at 1300 W and H3 at 1500 W. A separate fan-only mode runs the blower without heat. Amazon's table gives 1500 W and 12.5 amps at 120 volts, which is what 1500 W draws, and describes the product as '1000-1500 Watts'.
ECO mode is the one that behaves like a thermostat. You set a target between 41 and 95 degrees Fahrenheit in one-degree steps, and the manual says the heater picks its own heating power based on the gap between the set and ambient temperature, running at 1000 W or 1500 W when the room is below target and switching off about thirty seconds after the room reaches it. The manual's own troubleshooting note is that if it cuts out too often you should raise the set temperature or go back to Power Heat.
Other controls the manual documents: a 0 to 12 hour auto-off timer, oscillation on or off, a mute option for the button beeps, and a memory function that restores the last temperature, mode and oscillation state when you switch it on again. The display dims to off after one minute.
Three feet in front, and not in a bathroom
The manual's location rules are the part most buyers skip. It says to keep combustible materials such as furniture, pillows, bedding, papers, clothes and curtains at least three feet (0.9 m) from the front of the heater, and to keep them away from the sides and rear. A separate bold caution repeats that electrical cords, drapery and other furnishings stay three feet from the front and away from the side and rear.
It also says this heater is not intended for use in bathrooms, laundry areas and similar indoor locations, and that it must never be placed where it could fall into a bathtub or other water container. Do not use it outdoors. Do not stand it on soft surfaces such as a bed, where the openings can be blocked, and do not use it where gasoline, paint or flammable liquids are used or stored.
Amazon's table gives the body as 6.69 inches deep, 5.51 wide and 10.31 high and 3.85 pounds; we found no maker page repeating those figures, so treat them as listing data. The footprint is small, but the three-foot rule in front is what actually decides where it can sit.
It has to reach a wall outlet on its own
The electrical section says always plug heaters directly into a wall outlet or receptacle, and never use the heater with an extension cord or a relocatable power tap, which is the formal name for a power strip. It also says not to run the cord under carpeting, not to cover it with throw rugs or runners, and not to route it under furniture or appliances.
That rules out a lot of desk and bedside placements. Measure the distance to a free wall outlet before buying, because the manual gives you no sanctioned way to extend the cord. The manual adds that it is normal for the plug and cord to feel warm, but that a plug or cord which becomes hot to the touch or distorted points to a worn outlet that should be replaced.
The plug is polarized, with one prong wider than the other, and the manual says not to defeat that feature. It also says to turn the controls off before pulling the plug, and to unplug the heater whenever it is not in use.
Tip-over and overheat cut-offs, and an auto-off that starts switched off
The manual states both protections plainly and tells you what you will see. If the heater is tipped over it shuts off automatically and shows the code P4 on the display. If it overheats it shuts off automatically and shows FF. The troubleshooting table adds E1 and E2 for temperature sensor faults, which it says need Dreo customer support rather than a home fix, and repeats that an FF unit should be unplugged and left to cool before it is plugged in again.
There is also a 24-hour auto-off, and the manual is explicit that this feature is not on by default. You turn it on by holding the timer button for three seconds while the heater is on standby, and the display shows ON or OF. If you want a heater that will not run indefinitely on its own, you have to switch that on yourself.
The listing calls the package 'Shield360' and says it is ETL-listed; the back page of the manual carries an ETL Intertek mark. The manual also warns that the remote's CR2025 coin cell can cause serious internal injury or death if swallowed, which matters in a house with small children.
Filter care, warranty limits, and the numbers that do not agree
Upkeep is light. The manual says to switch off and unplug before cleaning, wipe the outer surface with a soft dry cloth, and clear dust from the air inlet with a dry cloth or a cotton-tipped swab. The dust filter pulls out of the back, rinses under running water and goes back once it is dry; Dreo suggests cleaning it every two to four weeks. Do not unscrew the unit, do not use cleaning agents or abrasive scrubbers, and never immerse it or let water inside.
The warranty in the manual is twelve months from the date of original purchase. Dreo lists seven exclusions, including accident, misuse, repairs by unauthorized personnel, commercial use, normal wear of wearable parts, and damage from not following the user manual. It also says Dreo can only provide after-sales service for products sold by Dreo or by Dreo authorized retailers and distributors, and sends other buyers back to their seller. Amazon's warranty field says twelve months, extendable to thirty by registering the product, which is Dreo's separate registration offer and not the default term in the manual.
Two published figures disagree with each other. The listing's bullet says the heater is 'as quiet as 37.5 dB' while the comparison table on the same listing gives a sound level of 34 dB; neither comes with test conditions, and we did not measure anything. The listing's 200 square feet of heating coverage is a maker claim with no stated room, insulation or starting temperature, and the manual makes no room-size claim at all. Treat both as marketing figures rather than specifications.
