Best Smart Space Heaters

Prices in this article are U.S. manufacturer prices checked November 2026. All assessments are research-based and untested.

Section 1: Which smart space heater is worth buying? (Introduction)

The best smart space heater is the Dreo 719S at $129.99: a 1,500 W wall panel with app schedules, Alexa and Google control, and a 41–95°F thermostat. It costs less than the portable alternative and suits a room you heat on a schedule.

A space heater is one of the few appliances where the connected version is not automatically the better one. The category is genuinely small. Dreo sells a handful of app-connected wall panels, Dyson sells a purifier that also heats, and Dreo’s tower heater line does not advertise app control. Nothing here was supplied or tested by a manufacturer. Every price is a U.S. manufacturer price checked on 10 November 2026, and Dreo’s store was running a seasonal sale, so treat the numbers as temporary rather than list prices.

Section 2: Do smart features make a heater better, or just more convenient?

Smart features add scheduling, voice control and remote shutoff, but they do not change the physics or the safety rules, so the heater type and the circuit matter more than the app.

Wi-Fi buys three things on a heater. You can put it on a schedule from your phone, you can turn it on or off with a speaker or an app while you are in another room, and you can check that you switched it off after leaving. Those are real conveniences, and for someone with limited mobility they are more than that. None of them makes the heater safer. The U.S. Consumer Product Safety Commission estimates that portable heaters, including electric space heaters, are involved in an average of 1,600 fires a year, with 70 deaths and 150 injuries annually from 2020 to 2022. Its guidance is blunt: keep the unit at least three feet from drapes, furniture and bedding, plug it directly into a wall outlet rather than an extension cord or power strip, and turn it off when you are sleeping.

That last rule is the one that matters for a buying decision. The automation people want most, a warm bedroom that runs all night, is exactly the automation the safety agency says not to build. A smart heater is a good fit for a home office that is cold from 8 a.m. to noon, a bathroom that needs ten minutes of heat before a shower, or a basement room you use in the evening. It is a poor fit for overnight sleeping, for a room with a pet that moves furniture, or for anyone who wants the app to substitute for being in the room.

The second decision is the heater type. A wall panel, which is what four of the five picks here are, gives up floor space and cannot be knocked over, but it needs a mounting spot, a stud or proper anchors, and a landlord’s permission if you rent. A portable purifier-heater can move between rooms and filter the air while it runs, at the cost of floor space, a higher price and the tip-over risk that comes with any freestanding unit.

The third decision is the circuit, and it is the one buyers skip. A 1,500 W heater draws 12.5 amps at 120 volts. A standard bedroom circuit is 15 amps, so the heater leaves very little headroom for a hair dryer, a kettle or a second heater on the same run. Dreo’s support notes for the 719S list “the outlet is not shared with other appliances” and “the heater is not plugged through an extension cord” among the checks, which matches the federal guidance. This is also why a smart plug is the wrong way to make a dumb heater smart: a 1,500 W continuous load sits too close to the limit, and the smart plug guide already says heaters should not go through one. Buy the heater with the radio inside it.

Section 3: How do the five heaters compare on price and control?

The four Dreo panels share the same app and thermostat, and the Dyson is the only pick you can carry from room to room.

The table is a price ladder with one jump in it. The four Dreo rows share a 1,500 W element, a 41–95°F thermostat with 1°F steps and the Dreo app. Only the 719S page names Alexa and Google; the other three describe app scheduling and control. What separates them is airflow and installation: the 517S tilts its outlet by hand, the 719S oscillates through 120 degrees, and the 711S has no fan at all. The Dyson row is a different product category. It heats, but it also carries a HEPA H13 filter, oscillates through 350 degrees and costs more than three times the 719S. If you only want warm air on a schedule, that premium buys nothing. If you also want cleaner air in the same footprint, it buys two devices in one.

Four of the five picks are Dreo because Dreo is the only brand with a full line of app-connected panels at a published U.S. price. That is a limitation of the category, not an endorsement. The category has more names than this table suggests: Pelonis lists a 30-inch smart ceramic tower with Alexa and Google control, but its own product page sends buyers to Amazon without a price, so it could not be compared on the same dated basis. If a tower is what you want, that is the one to check yourself.

Compatibility is narrower than the prices suggest. Dreo’s 719S page lists Alexa and Google; the 517S, 517AS and 711S pages describe app control and scheduling without naming voice assistants. None of the four lists Apple Home, SmartThings or Home Assistant. Dyson lists the MyDyson app and compatible voice services without naming them on its category page. If your house runs on Siri or Home Assistant, check the vendor’s current integration list before buying; none of these is a local-first device.

One caveat on the prices: they are manufacturer sale prices, not street prices. Dyson lists the HP1 at $449.99 against a regular $659.99, and Dreo’s panels were discounted in the same seasonal sale. Both brands move these numbers often, so check the current figure before you decide the gap between the 517S and the 719S is worth $30.

Section 4: What goes wrong when a smart heater runs on a schedule?

The schedule keeps running when the room, the household or the network changes, and those are the cases that cause trouble.

The thermostat is not where you are. A wall panel measures the air moving through its own body, not the temperature at the sofa or the desk. Heat collects near the ceiling, so a panel mounted high reads warm air and can shut off while the floor is still cold. A panel mounted low reads colder air and runs longer, which warms the room but costs more. Pick the height where the reading matches how the room actually feels, and check the app against a thermometer across the room before you trust a schedule built on it.

The circuit is shared even when the outlet is not. Two bedrooms on one breaker, a space heater and a hair dryer on the same circuit, or a heater plugged into the same outlet as a television all end the same way: a tripped breaker, or a warm plug. If the breaker trips every time the heater runs, the answer is a different circuit, not a bigger breaker. A 1,500 W heater on a 15 A circuit is already close to the ceiling.

The internet is part of the heater. Dreo’s product pages describe app scheduling but do not promise that schedules keep running when the connection drops, so treat the schedule as cloud-dependent. When the Wi-Fi or the vendor’s service is down, the panel still heats from its own buttons, but the app stops reaching it. Dyson’s MyDyson app has the same shape: control from anywhere needs the internet, and the unit’s own controls are the fallback.

Guests and pets do not read the app. A wall panel avoids the classic tip-over accident, but the three-foot clearance rule still applies to curtains, bedding, drying laundry and anything stacked below the unit. A portable unit adds the tip-over risk back. If the household includes a cat that sleeps on warm surfaces or a child who moves furniture, a wall panel keeps the heating element off the floor, which is the safer shape.

Maintenance is the filter and the dust. The 719S has a reusable filter that needs rinsing, and every panel collects dust on its intake grille. A clogged filter or a blocked grille makes the thermostat lie, because the unit runs hotter for the same room temperature and cycles sooner. The fanless 711S has no filter to wash, which is one reason it suits a bedroom or an allergy-prone household, but its fins still need dusting.

Sleep is the line. CPSC says turn heaters off when sleeping, and no app setting changes that. If your plan depends on the heater running from midnight to 7 a.m., the honest answer is a warmer duvet, a heated mattress pad or a heat pump, not a smarter heater.

Section 5: Which heater fits which room?

Buy the Dreo 719S for most rooms, the 517S if price decides, the 517AS for a bathroom, the 711S for a quiet bedroom, and the Dyson HP1 only if you want the purifier as well.

Dreo 719S: best overall

The 719S is the best overall because it is the cheapest oscillating panel here. It runs a 1,500 W PTC element, oscillates through 120 degrees, holds a set temperature between 41 and 95°F in 1°F steps, and connects over 2.4 GHz Wi-Fi to the Dreo app, Alexa and Google. Dreo also fits a reusable filter and a detachable front panel, and covers the unit with a 12-month warranty.

The trade-off is installation. It is a wall unit, so you need a spot with clearance, a stud or anchors, and a nearby outlet that is not already carrying a heavy load. At $129.99 it is the pick most people should buy, but only if the wall is yours to drill.

Dreo 517S: best budget

The 517S is the same 1,500 W heater with fewer moving parts. It has three heat settings, a fan-only mode, a 41–95°F thermostat, a 30-degree manual outlet tilt and a 24-hour timer, all through the same app. At $99.98 it saves $30 against the 719S and gives up the oscillation and the filter.

The trade-off is that you aim it by hand. If the room is a hallway or a bathroom where you want heat in one direction, that is fine. If you want the heat to spread across a living room, the 719S earns its extra $30.

Dreo 517AS: best for bathrooms

The 517AS is the 517S with an ALCI plug on the cord, which adds leakage-current protection at the plug. That makes it the sensible choice for a bathroom or a kitchen, where water and electricity share a room, and it costs $119.99.

The trade-off is that the ALCI plug is cord-level protection, not a substitute for the GFCI outlet a bathroom should already have. It also does not change the placement rules, so keep it out of spray range and mount it where splashes cannot reach it.

Dreo 711S: best for quiet rooms

The 711S is the quiet pick because it has no fan. It is a 1,500 W convection panel that heats by moving air across hot fins, which Dreo markets as 0 dB, with IP24 splash resistance, three heat levels and an ECO mode the company claims can cut energy use by up to 40%. It uses the same app and the same 41–95°F range, adds an open-window alert, and costs $169.99.

The trade-off is speed. A fanless panel warms a room slowly and quietly rather than quickly and loudly, and the 40% figure is a manufacturer claim, not an independent test. It is also a wall-mounted unit, not a floor model.

Dyson Purifier Hot+Cool HP1: best portable

The HP1 is the only pick here that is both a heater and an air purifier, and the only one you can move. It combines a heater with a fully sealed HEPA H13 filter, 350-degree oscillation, the MyDyson app and compatible voice services, and it carries an Energy Star rating and a two-year warranty. It was $449.99 on Dyson’s site on 10 November 2026, down from $659.99, though at least one finish showed as out of stock.

The trade-off is the price and the physics. It is the most expensive pick by a wide margin, it takes up floor space, and Dyson’s U.S. category page does not publish a wattage, so check the label if running cost is the deciding factor. Buy it for a room where you want cleaner air and supplemental heat from one device. Skip it if you only need warmth.

Section 6: What is the final call? (Conclusion)

The default answer is the Dreo 719S at $129.99, because it is the least expensive panel here that schedules, takes voice commands and spreads heat across a room, and it comes from the manufacturer with a 12-month warranty. If the wall is not yours to drill, the Dyson HP1 is the only portable pick, and it is worth the money only if you value the filter.

Skip all of these if the room is cold because the house has no insulation, a failed window seal or a heating system that needs repair. A $130 panel treats the symptom and adds about $65 a month to the bill at the U.S. average residential rate of 18.16 cents per kilowatt-hour in August 2026, based on 1,500 W for eight hours a day. Fix the envelope first.

Before ordering, do two checks: confirm the outlet is on a circuit that can carry 12.5 amps on its own, and stand where the panel will mount to confirm it is at least three feet from anything that can burn.
