High Ondol is a furniture‑style radiant heating platform that translates the wisdom of Korea’s traditional ondol into a clean, modern appliance. At its core is our proprietary Inergy Bar heat‑storage module: a self‑regulating ceramic heater energizes a sealed heat pipe, which transfers heat rapidly into a loess (Hwangto) thermal mass. A precision aluminum manifold then spreads the energy evenly across the surface, releasing a gentle, body‑friendly radiant warmth that lingers long after power input falls. Because High Ondol stores before it radiates, it feels deep and natural—no fans, no ducts, no drafts, and far less dryness than hot‑air heaters.

Designed for true plug‑and‑play use, High Ondol sits on your existing bed x-frame or floor and connects to 220–230 V, 50/60 Hz power. The heating architecture is engineered without electric heating wires or films, supporting an EMF‑free design at the point of heat generation. A capped 45 °C maximum surface temperature and the inherent self‑regulation of the ceramic heater contribute to everyday safety and peace of mind. With no pumps, motors, or circulating water, operation is silent and maintenance is minimal; the dry, no‑plumbing design also avoids leaks, freeze, and combustion concerns.

Built like premium furniture, the body uses eco‑friendly birch plywood for structural stability, while the surface is finished in HPM (High Pressure Melamine) for superior resistance to scratches, stains, and moisture. The modular construction enables component‑level service, reducing downtime and extending product life. When your life moves, High Ondol moves too: from bedroom to studio, rental to tiny home, cabin, or camper van, it delivers localized, efficient heating precisely where you spend time, helping you feel warmer on less energy instead of heating unused rooms.

Choose the size that fits your space: H1 (400 × 2000 × 78 mm, 215 W), H2 (800 × 2000 × 78 mm, 410 W), or H3 (1100 × 2000 × 78 mm, 570 W). All models share the same 45 °C surface cap and CE certification, with custom sizing available within ±200 mm (width/depth). From ondol to High Ondol, it’s a straight line: timeless radiant comfort, engineered for modern living—set it down, plug it in, and enjoy quiet, even, enduring warmth anywhere you call home.
