The Wall Heater is an industrial-residential hybrid fixture container typically mounted directly onto interior walls in buildings such as apartments, hospitals, offices, and mixed-use facilities. It visually resembles a small heating unit or radiator system embedded into the wall. It is often overlooked. This is a breach-required container, meaning interaction locks you into a longer opening animation and leaves you fully exposed. Wall Heaters are almost always found indoors, which means you are typically breaching them in confined spaces where enemy contact, audio detection, or ambush risk is significantly higher. The loot pool is low-to-mid tier and narrowly focused on electrical and mechanical basics. Common drops include Electrical Components, Metal Parts, Plastic Parts, Wires, Rubber Pads, and Voltage-related components. These are standard crafting materials used for early-to-mid progression systems, but they lack high-value variance or rare loot spikes. Unlike higher-tier industrial containers, the Wall Heater does not offer meaningful high-end rewards. It is consistent but unexciting, with most outcomes falling into basic crafting resource categories. At best, it functions as supplemental material sourcing rather than a primary loot target. Generally skip unless convenient. Wall Heaters are not inefficient in isolation, but the combination of low loot ceiling + breach requirement + indoor exposure risk makes them poor value compared to other containers. Only loot if you are already clearing the room, specifically need basic electrical/mechanical materials or XP, or if there are no higher-priority containers nearby. Otherwise, this is a low-priority industrial filler container best left behind in optimized runs.
