It heats, humidifies, and you control it from your phone. The Siguro Theravox fan is half price at Alza!

Ceramic fan with Wi-Fi and humidifier for one thousand two hundred fifty. The Siguro Theravox M300B is available at Alza for 1,250 CZK with code ALZADNY50. For that price, you get a tower fan heater with 2,000 W, which will heat a room up to 20 m², humidify dry air in winter, and you can control it from your phone — even if you’re on the other side of town. Ideal for a study, bedroom, bathroom, or a cottage.

Quick summary:
✅ Makes sense if you want smart supplementary heating with an app, timer, and humidification — for a price at which you would otherwise only buy a basic electric heater.
⚠️ Consider that after a power outage, the device will not start automatically without manual confirmation on the unit itself — a problem for remote control of a cottage.
💡 For 1,250 CZK, you get PTC ceramic heating, Wi-Fi with TUYA Smart app, oscillation, humidifier, remote control, eco mode, and a 3-year warranty.

What you get for it

Two power levels (1,300 and 2,000 W), temperature setting 15–35 °C with degree accuracy, 80° oscillation for even room heating. Eco mode automatically switches between power levels according to the current temperature — below 18 °C it heats at full power, between 18–25 °C it runs economically, above 25 °C it switches off. The anti-freeze function maintains the temperature around 7 °C — useful in a cottage or garage in winter.

Integrated backlit water tank humidifies the air, touch panel, remote control with battery included, and control via TUYA Smart — you can set temperature, timer, and oscillation from your phone. Safety features include automatic shutdown upon tipping, thermal fuse, and disconnection after 12 hours of continuous operation. Noise level 45 dB. Warranty period 3 years with the option of immediate replacement at an Alza branch.

What to expect

One user on Alza points out an important drawback for remote control: after a power outage, the fan does not start automatically because it waits for confirmation of the humidifier function via a button on the unit. The app does not notify you of this — you might think it’s heating, but the device is off. If you plan to control the fan purely remotely (e.g., pre-heating a cottage), this is a significant limitation. For home use, where you are on-site, it’s not a problem.

How do you provide supplementary heating during transitional periods — with a fan, infrared panel, or a classic radiator?
