Warmth without dry air or draughts: The Klarstein MarmoHeat uses infrared radiation to warm surfaces and people directly — not the air in the room. There's no fan, no circulating dust, and no parched atmosphere. Perfect for bedrooms, children's rooms, and home offices where air quality matters.
Feel the heat almost immediately: Infrared works fast — you'll notice the warmth within 2–3 minutes of switching on, with no warm-up phase. The 600 W output spreads evenly across the room, so there are no cold spots to contend with.
Noticeably lower heating bills: With energy efficiency class A, the MarmoHeat uses up to 50% less electricity than a conventional electric heater. Pair that with the built-in thermostat and programmable timer, and you're only using energy when you actually need it.
Set it and forget it: The integrated thermostat keeps your chosen temperature steady without constant adjustment. The weekly timer programme lets you automate your heating schedule completely. Built-in overheat protection with automatic shut-off gives you peace of mind around the clock.
Mounts flush — barely notices itself on the wall: The slim aluminium panel fixes to a wall or ceiling with standard rawlplugs, and all the mounting hardware you need is included in the box. Its understated design sits quietly in any modern interior without drawing attention to itself.
Product description
When the radiators are clanking and the air feels parched, there's a better way to heat a room. The Klarstein MarmoHeat uses infrared technology to warm people and surfaces directly — the same principle as sunlight — delivering gentle, even heat without drying out the air or circulating dust. At 600 W, it's a genuinely efficient alternative to conventional electric heaters, and it works beautifully in a living room, home office, or bedroom.
Unlike a fan heater, infrared doesn't heat the air first — it heats you. That means you feel the warmth within 2–3 minutes, with no waiting around and no draughts. For anyone who suffers from allergies or dry sinuses in winter, that makes a real difference. Energy efficiency class A means the MarmoHeat uses up to 50% less electricity than a standard electric heater — savings that add up over a season.
The slim aluminium panel is built to last, with a quality lacquered finish that wipes clean with a damp cloth. It can be mounted on a wall or ceiling using standard rawlplugs — all necessary fixings are included in the box. It runs on 220–240 V / 50/60 Hz and is CE certified to EU safety standards.
Its flat, unfussy design means it disappears into a modern room rather than dominating it. Whether you're topping up your central heating on cold days, settling into a new flat, or heating a freshly renovated space, the MarmoHeat delivers quiet, consistent warmth year-round.
Stay warm this winter with the Klarstein MarmoHeat — order yours today.
