Warmth without the dry air or draughts: The Klarstein MarmoHeat uses infrared radiation to heat surfaces and people directly — not the air in the room. There's no fan, no circulating dust, and none of that parched, over-heated feeling you get from conventional heaters. Ideal for bedrooms, children's rooms, and home offices.
Warmth you feel in minutes: No waiting around for the room to heat up — infrared warmth is noticeable within 2–3 minutes of switching on. The 600 W output spreads evenly across the space, so you're comfortable quickly rather than waiting for the chill to slowly lift.
Noticeably lower heating bills: Energy efficiency class A means the MarmoHeat uses up to 50% less electricity than standard electric heaters. The built-in thermostat and programmable timer make sure it only runs when you actually need it — no wasted energy, no forgotten heaters running through the night.
Set it and forget it: The integrated thermostat keeps your chosen temperature steady without you having to keep adjusting it. The weekly timer programme lets you automate your heating schedule entirely, and the automatic overheat protection shuts the unit down safely if it ever needs to.
Fits flush to the wall, disappears into the room: The flat aluminium panel mounts to walls or ceilings using standard wall plugs — all necessary fixings are included. Its clean, minimal design sits comfortably alongside modern interiors without looking like a utility appliance.
Product description
Cold radiators, dry air, and the constant hum of a fan heater — there's a better way to heat your home this winter. The Klarstein MarmoHeat infrared panel heater warms you the same way the sun does: directly, silently, and without stripping the moisture from the air. At 600 W, it's a genuinely efficient alternative to conventional electric heaters, and it's at home in any living room, home office, or bedroom.
Unlike traditional heaters that warm the air (which then rises straight to the ceiling), infrared radiation heats surfaces and people directly. You feel the warmth within 2–3 minutes of switching on — no warm-up wait, no draughts, no dust being kicked around the room. That makes it particularly good for bedrooms and children's rooms where air quality matters. Energy efficiency class A means the MarmoHeat uses up to 50% less electricity than conventional electric heaters.
The slim aluminium panel is built to last, with a high-quality lacquered finish that wipes clean with a damp cloth. Wall and ceiling mounting brackets and all necessary fixings are included in the box — installation is possible with standard wall plugs. The MarmoHeat runs on 220–240 V / 50/60 Hz and is CE-certified to EU safety standards.
Whether you're supplementing your central heating, settling into a new flat, or finishing a renovation, the MarmoHeat slots quietly into modern interiors without drawing attention to itself. Flat, unobtrusive, and genuinely useful year-round.
Order yours today and find out how comfortable — and how quiet — heating can be.
