550-Watt Graphene Wall Heater — Fanless Silent Convection Heating

A 550-watt graphene wall-mounted convection heater engineered for completely silent, fanless operation — no moving parts, no airborne dust, and ideal for asthma or allergy sufferers. Its minimalist exterior is designed to blend into both home interiors and office environments. Performance and efficiency: built around a high energy-saving heating element and a customized energy-saving chip, the unit includes a high-precision temperature sensor and an inverter to maximize electricity savings. It delivers a short-time fast temperature rise and then maintains a long-lasting, energy-efficient constant temperature. Safety and testing: the heater features automatic overheating protection — it will shut off if internal components reach a temperature that could cause overheating or fire. This protection meets U.S. UL standards, and each unit has passed rigorous factory testing. Construction and materials: frame corners use environmentally friendly ABS pure new material, and the internal insulation is a B1 grade flame retardant polyurethane insulation board.
