1. Product Description

Our Direct Heat Type Electric Heater is a compact, high-performance thermal solution designed for immediate and efficient space heating. Utilizing direct electric-to-heat conversion technology, it eliminates intermediate energy storage, delivering instant warmth within seconds of activation. Available in two models—SL-0201 (single-phase, 1000W) and SL-0202 (dual-mode, 1000W/2000W)—it caters to flexible heating needs, from small residential spaces to compact commercial areas. Constructed with a durable metal casing and optimized heating element, it ensures stable performance with minimal heat loss. Ideal for quick temperature adjustment, it features a slim profile (e.g., 150×300×600 mm) for easy installation in tight spaces.
