K-Infrared Stone Culture Leader, Onsunnuri

Onsunnuri is a leading electric heating pad brand that conveys the warmth and health of nature through infrared stone heating. Founded in 2005, Onsunnuri launched Omats in 2007 as the "Onsunnuri" brand and has been advancing the globalization of K-infrared stone culture. Starting with 110V electric heating pads, it is preferred worldwide, especially in Canada, New Zealand, and Japan, through official export contracts with local companies. Onsunnuri develops and sells electric heating pads that meet the needs of customers everywhere.

Onsunnuri Always Ponders

"Infrared stone" is the perfect heating culture that God granted to our descendants and humanity through the wisdom of our ancestors. Onsunnuri embraces this wisdom and technology to commercialize and share this radiant heating culture globally. Aiming to become the global No. 1 company in radiant heating and cooling systems, comfort temperature is considered a top priority for human living conditions. Especially, sleeping temperature significantly affects the next day's well-being, and the biggest advantage of infrared stones is the gentle warmth maintained even when turning off the power due to residual heat.

Additionally, scientific evidence suggests that infrared stone heat therapy helps fatigue recovery. Onsunnuri uses yellow soil balls to develop radiant heating mats emitting far-infrared rays. This traditional Korean infrared stone technology provides not only electric heating pads but also various other products.

Point 1: 110V Exclusive Overseas Use Heating Boiler

Developed exclusively for 110V overseas use, this electric heating boiler is certified by PSE, CE, CB, and CQC for overseas export and use. Please purchase only the "Overseas Use" model for overseas use.

This product is a 110V exclusive product usable only in the specified region. It is shipped as type B (right-side plug). Please note that adapters for different countries need to be purchased separately.

Point 2: BLDC Motor Electric Heating Boiler

Why is the "BLDC motor electric heating boiler" reputed to be good?

First, the internal pipe heats water, and secondly, the water stored in the tank is also heated by a dual indirect heating method allowing faster heat circulation compared to natural circulation electric boilers.

What Is the Difference Between Motor and Natural Circulation?

  • Motor Electric Boiler: Dual indirect heating by BLDC motor quickly and powerfully heats water, circulated through the heating hose.
  • Natural Circulation Electric Boiler: No motor, water circulates by pressure difference via instantaneous heat.
  • Size: Motor 160 x 210 x 110 mm / Natural 290 x 210 x 130 mm
  • Weight: Motor 1.4 kg / Natural 1.5 kg
  • Voltage: AC 220V 60Hz (Overseas 110V for motor) / AC 220V 60Hz (Overseas 110~240V for natural)
  • Power: Motor 350W / Natural 251W (Separate heating 502W)
  • Water Tank: Motor 400 ml / Natural 550 ml
  • Noise: Motor small noise during operation / Natural almost no noise

Point 3: Noise Reduction Using V-Type Ceramic Bearing

Using diamond-hard special PIVOT V-type ceramic bearing for automatic connection to the device minimizes boiler noise with minimal contact and rotation, preventing motor seizure issues from long-term use.

What Is Motor Seizure?

Repeated prolonged use and storage causes foreign substances, rust, scale, etc., creating noise and motor performance degradation (pumping loss) in the motor drive shaft.

Point 4: Safety from 10-Step Safety System

The most important consideration in manufacturing Onsunnuri heating pads is "Safety." The robust 10-step safety system alerts the user via warning sound and error code in case of system failure or program error.

  • Overcurrent fuse: Automatically cuts off in overload
  • Bimetal: Cuts off power when overheating
  • Temperature sensor: Maintains set temperature
  • Water shortage sensor: Stops if water is insufficient
  • Self-diagnosis mode: LED display error code when abnormal
  • Anti-freeze: Stops operation below set temperature
  • Fire prevention: Automatic power cut when hot
  • Electric power safety switch: Automatically cuts power in case of shock or movement
  • Pump safety: Stops motor and repeats automatic stop if overworked
  • Safety cover: Prevents hand contact with water tank

FAQ: Important Before Purchasing

  1. Error stating water shortage when first turning on power?

    When first using, connect hose with power off, then turn on power and add water slowly. About 1 to 1.3 liters is needed since water circulates inside the mat.

  2. Should the heating boiler be at the same height as the mat?

    If hose bends or kinks, place the boiler parallel or below the mat for best use.

  3. Hose is bent but still warm when lying down?

    Use a pad or thin blanket on top for better warmth since heat is radiated; exposure to air cools faster.

  4. Power turns off automatically?

    Built-in level stabilizer may shut off power if placed unevenly on carpet or towel.
