DREO 729BS vs 739AS: FortPlug or ALCI?
DREO’s Wall-mounted Heater 729BS and Wall-mounted Heater 739AS are close neighbors in the wall-heater lineup, but their plug features are not synonyms. The 729BS is identified in its DREO-branded instructions as DR-HSH009BS, with WH729S used in Wi-Fi setup; the 739AS instructions identify DR-HSH009AS and WH739S. Both are fixed-wall fan heaters with app scheduling and different cord-plug protection descriptions. Neither should be selected for a bathroom: each exact manual warns against water or wet-area use.
FortPlug and ALCI solve different problems
The 729BS manual calls its plug feature FortPlug and describes it as restorable overheat protection. A plug-temperature problem can stop heating and show “PP”; the instructions tell the user to unplug and check the receptacle and cord conditions before restoring power. The 739AS manual instead describes an appliance-leakage-current interrupter (ALCI) with TEST and RESET controls. An overheat cutoff and a leakage-current interrupter are not interchangeable protections. If your requirement is specifically an ALCI TEST/RESET plug, the 739AS is the documented choice of this pair; 729BS should not pass that requirement on the strength of its FortPlug label.
That does not make the 739AS a wet-location heater. The 739AS manual says not to use the appliance near water and warns against places where it could fall into a tub or other water container. The 729BS manual says it is not intended for bathrooms, laundry rooms, or similar locations. A protective plug is not waterproofing and does not supersede the manual. If you need a bathroom heater, neither of these documented operating plans qualifies.
Shared routine, separate model identities
Both manuals rate their appliances at 1,500 watts, 120 volts, and 60 hertz. Each has 900-, 1,300-, and 1,500-watt heat levels, a 41–95°F ECO temperature target, and separate Fan Only operation. They are fan heaters rather than fanless convection panels. Each supports DREO app scheduling and a local countdown that turns off an already-running heater; do not confuse that countdown with a delayed start. Both manuals provide 60°, 90°, 120°, and oscillation outlet-angle choices without identifying the movement axis in their control descriptions. The manufacturer pages make broader claims about the airflow, but an angle figure alone is not independent proof of a horizontal sweep or even room temperatures.
The exact U.S. product records also differ. The 729BS listing has one Default Title variant, SKU 10-04009-113, and the 739AS row has one Default Title variant, SKU 10-04009-114. Their matching instructions carry different model labels and app pairing names. Do not substitute the 739AS manual or plug photograph for a 729BS, even though both products mount to a wall and share the DR-HSH009 family prefix.
Installation makes the decision less glamorous—and more useful
Neither is portable. Both manuals require wall installation rather than propping the unit up, and both need an outlet and wall position that preserve their specific clearances. The 729BS diagram gives at least one foot above and below and more than 0.65 foot on each side; its manual also calls for combustibles three feet from the front and away from the side and rear. The 739AS manual likewise specifies a three-foot front clearance and side/rear separation, but do not transfer another model’s drawing to it. Check the exact supplied installation diagram, wall construction, cable route, and heater body dimensions before drilling. The DREO studio images show product appearance, not a scaled fit drawing.
Which one belongs on your list?
Shortlist the 729BS when plug-area overheat protection is the feature you specifically value, provided that its dry-room wall installation and schedule behavior fit your routine. Shortlist the 739AS when a documented ALCI TEST/RESET device is your specific preference, but do not treat that feature as permission to put the heater near a sink or tub. If the key need is simply app access, thermostat control, or Fan Only mode, compare the full installation and safety instructions rather than assuming the plug difference settles the choice. If neither mounting position works, move to a floor heater; if you want no fan airflow, examine a convection panel instead.
For matching, the safe positive need is “dry indoor, wall-mounted fan heat” with a single plan that meets the placement and electrical rules. A bathroom requirement rejects both. An ALCI requirement points to the 739AS, while a FortPlug-overheat requirement points to the 729BS; unknown or differently named protection does not satisfy either essential condition. Read the full 729BS assessment and 739AS assessment beside their distinct 729BS maker listing and 739AS maker listing. This is a manual-led comparison, not an electrical safety test or a measured heat-output ranking.
