- Controls and features: Thermostats help maintain steady temperatures. Timers and eco modes improve energy efficiency. Remote or touch controls add convenience.
- Safety and clearances: Look for overheat protection, child locks, and rugged grills. Ensure adequate clearance from furniture and combustible materials.

FAQ
- What size heater do I need for a 150 sq ft room?
Most 120V units rated around 1500W can heat 100–150 sq ft when used in isolation, though insulation and ceiling height affect performance. Consider a second unit for larger spaces.
- Are in-wall heaters safer than portable heaters?
In-wall heaters have fixed installation and often built-in safety features; portable space heaters require careful placement to avoid tip-overs and overheating.

Installation typically requires electrical work and adherence to building codes. A licensed electrician is recommended for proper wiring and secure mounting.

Keep grills clean from dust, inspect wiring if accessible, and ensure the thermostat and timer functions operate correctly. Do not attempt internal repairs beyond the manufacturer’s guidance.

Models with Eco mode, timers, and remote controls tend to reduce energy use by targeting heat and scheduling comfort precisely for your space.
