[Used] HeatSquare Smart 350W 60x60cm Infrared Panel Heater​ Anthracite

• Warm the moment you switch on: Infrared radiation heats surfaces and people directly — not the surrounding air. Full heating output is noticeable within 2–3 minutes, with no warm-up phase required.

• Noticeably lower running costs: Energy efficiency class A means the HeatSquare uses up to 50% less electricity than a conventional electric heater producing the same level of warmth — a difference you'll see on your energy bills.

• Heat on your schedule: The built-in thermostat and programmable weekly timer let you set exactly when your room warms up and when the panel switches off — so you're never paying to heat an empty space.

• Completely silent — day and night: No fan, no airflow, no hum. With no moving parts, the HeatSquare operates in total silence, making it ideal for bedrooms, children's rooms, and home offices where noise or dust disturbance simply isn't an option.

• Neat, durable, and easy to mount: The slim aluminium housing with quality lacquer finish mounts to any wall or ceiling using standard wall plugs. CE certified and compliant with EU safety standards, it also wipes clean with a damp cloth.

Radiators that dry out the air. Convectors that stir up dust. Fan heaters that hum through the night. There's a quieter, smarter way to keep warm — and the Klarstein HeatSquare has been doing it all along.

Infrared heating works the way sunshine does: it warms surfaces and people directly, not the air around them. That means no draughts, no dust clouds, no parched throat in the morning — just steady, comfortable warmth that you feel within 2–3 minutes of switching on. No warm-up phase, no waiting. And with energy efficiency class A, the HeatSquare uses up to 50% less electricity than conventional electric heaters delivering the same heat.

The slim aluminium panel fits flush to a wall or ceiling using standard wall plugs — no specialist tools needed. Once it's up, the built-in thermostat, programmable weekly timer, and automatic overheat cut-off handle everything else. Set it to warm your room before you get home, then switch off automatically once you're asleep. The robust aluminium housing with quality lacquer finish wipes clean with a damp cloth.

Whether it's the living room, bedroom, children's room, or home office, the HeatSquare runs in complete silence — no fan, no airflow, no noise whatsoever. The flat, modern panel sits neatly against the wall without dominating the room. Rated at 220–240 V, 50 Hz and certified to CE and EU safety standards. 2-year guarantee included.
