DREO 739AS vs 719S: what the ALCI plug does—and does not—mean
DREO’s 739AS and 719S are both wall-mounted fan heaters with a 1,500-watt maximum, thermostat control, app access and a separate Fan Only mode. Their model names are close, but the plug protection and manual identity differ. The 739AS is the DR-HSH009AS with an ALCI plug; the standard 719S is WH719S / DR-HSH009S. This guide is about choosing between those exact wall-heater configurations, not about every product marketed for bathroom use.
What changes with the ALCI configuration?
The 739AS manual describes an appliance-leakage-current interrupter attached to the plug, with TEST and RESET controls. It gives a test procedure and says the ALCI is not intended as the heater’s on/off switch. The official DREO product page highlights this feature as part of its bathroom-safety pitch. That may sound like a decisive advantage if you are shopping for a bathroom, but the matching manual tells users never to use the appliance near water and warns against locations where it could fall into water. Treat the manual limit as controlling: do not use the 739AS near a bath, shower, sink, or other wet area merely because it has an ALCI plug. A ground-fault protection feature is not an IP waterproof rating or a substitute for model-specific permission.
The 719S does not have the ALCI feature. Its model manual likewise rules out bathroom and laundry use, so the absence or presence of ALCI does not make one of these two a safe wet-room choice. If a bathroom is the essential location, neither reviewed manual is a positive fit. Ask DREO for a model-specific written resolution if product-page language conflicts with safety instructions, and follow the stricter warning unless the manufacturer clarifies otherwise.
The models are not just plug variants
On the 739AS, the DREO US collection lists one Default Title variant, SKU 10-04009-114. The product page is titled Wall-mounted Heater 739AS; the matching manual identifies DR-HSH009AS and its app pairing steps call the device WH739S. The 719S collection entry has a separate single SKU, 10-04009-112, and its own manual identity WH719S / DR-HSH009S. Do not use a 719S installation or electrical assumption to fill a gap in the 739AS manual, or assume that a retailer’s abbreviated title settles which variant is being sold. Check the SKU and model label.
Both manuals describe three heat levels (900, 1,300 and 1,500 watts), ECO temperature control, Fan Only, a 0–24-hour auto-off countdown while running, and a separate app schedule. The local countdown does not document an off-to-on delayed start. App schedules are useful only if phone setup and network control fit your household; the remote provides another way to operate the heater but is not the same as a local schedule. The manuals also list angle control, but they do not name the angle axis in their control descriptions. So neither should be selected to satisfy a strict horizontal-swing or dual-axis requirement based solely on 60°, 90°, or 120° labels.
Wall fit and clearance still decide whether either model belongs
These are fixed wall installations, not portable heaters. A drill, suitable wall structure, safe cable route, and permanent position matter before you get to smart features. The 739AS manual requires at least three feet in front from combustibles and distance from sides and rear; it instructs that the heater be installed on a wall and not propped on another object. The 719S manual also requires wall mounting and gives a three-foot front combustible clearance. Neither short product name nor a studio image tells you the complete installed wall envelope. Verify width, depth, fixing points and every current clearance in the exact manual before drilling or deciding a tight space will work.
The 739AS maker lists a 70.8-inch cord, but that alone cannot show whether your outlet and mounting point align without an unsafe extension or an awkward route. DREO’s comparison page gives a body height for the separate 719S; do not transfer it to the 739AS. If body dimensions, a specific outlet location, or the installation margin is essential, require a 739AS-specific drawing or manual figure rather than treating missing information as a pass.
A practical choice
Choose the 739AS only when the ALCI test/reset plug is a meaningful feature for your dry indoor wall-heating plan, the mounting position meets the model’s clearances, and the app schedule and fan heater behavior suit you. Do not choose it on the assumption that the ALCI makes bathroom use acceptable. Choose the 719S if you want the same broad wall fan-heater routine without the ALCI plug and have no essential need for that feature. Choose a portable floor heater if moving the appliance matters, or a fanless convection panel if you want wall-mounted heat without fan-forced airflow. Those are different operating arrangements, not interchangeable styles of this pair.
For either model, the sensible finder choices are wall mounting, indoor use, and Fan Only if those features are essential. An ALCI requirement identifies the 739AS; a bathroom requirement rejects it because the manual does not grant that permission. An essential numeric swing requirement should not be marked satisfied from an axis-unspecified angle label. This is a documentation comparison rather than a heat-output or safety laboratory test. Read the 739AS manufacturer listing beside its DR-HSH009AS manual, then verify the exact 719S manual separately before installation.
