The Types classification dissects the market into portable heaters, wall‑mounted panels, floor heating mats, and radiant cable systems. Portable heaters, encompassing convection, fan‑assisted, and infrared units, represent the largest share, roughly 40 % of type‑level revenue, due to their low capital outlay and ease of relocation across residential and small‑business settings. Wall‑mounted panels, accounting for about 25 %, are favored in retrofit projects where space constraints demand slim profiles and precise zone control, often integrated with smart thermostats. Floor heating mats, contributing 20 %, are embedded in new‑construction residential and commercial flooring, offering uniform heat distribution and compatibility with renewable electricity tariffs. Radiant cable systems, the smallest segment at 15 %, serve industrial and high‑bay applications where rapid surface heating and durability are critical. Each type’s engineering attributes—power density, installation flexibility, and control sophistication—directly affect its market contribution, informing the broader market taxonomy that guides manufacturers’ product roadmaps and investors’ allocation decisions.
