Top features

  • Even warmth from floor to ceiling: Convection airflow carries heat naturally throughout the entire room, so there are no cold corners or uneven warm patches — just a consistently comfortable temperature wherever you're sitting.

  • Holds the exact temperature you set: The electronic thermostat maintains your chosen room temperature to within ±0.5 °C, keeping conditions steady without the heater repeatedly switching on and off.

  • Quiet enough to forget it's there: Running at under 35 dB, the Bansin Crystal operates more quietly than a normal conversation — ideal for sleeping soundly or staying focused while you work.

  • Programme your heating a whole week ahead: The integrated 7-day timer lets you set a different schedule for every day, so the heater only runs when you actually need it — cutting unnecessary energy use on weekdays, weekends, and everything in between.

  • Slim, wall-mounted, and ready to go: At under 10 cm deep, the Bansin Crystal sits flush against the wall without taking over the room. It mounts without specialist tools or structural changes — perfect for renters who want to take it with them when they move out.

Product description

Renting, working from home, or heating a room that the central heating simply doesn't reach? The Klarstein Bansin Crystal is a slim electric convector that plugs straight in and gets to work — no plumber, no renovation, no fuss.

Convection heat rises naturally from floor to ceiling, filling the whole room evenly without the cold patches you get from cheaper panel heaters. At under 35 dB, it runs quietly enough for a bedroom or home office — you'll barely notice it's on. The precision electronic thermostat holds your chosen temperature to within ±0.5 °C, so the room stays consistently comfortable without the heater cycling on and off all evening.

The built-in 7-day weekly timer means you can programme different schedules for every day of the week — warm when you need it, off when you don't. That means less energy used overnight or when the house is empty. A dust guard protects the heating element and prevents that unpleasant burning smell when you switch it on for the first time each autumn.

The Bansin Crystal suits any space that needs reliable warmth without permanent fixtures: holiday lets, home offices, spare rooms, workshops, or older properties where the central heating never quite keeps up. Tenants can mount it without making any structural changes — and take it with them when they move. Power supply: 220–240 V, 50 Hz.

Order the Klarstein Bansin Crystal today and enjoy steady, programmable warmth wherever you need it most.

Wir haben einige Wandkonvektoren ausprobiert (Dreo, StiebelEltron) und sind bei dem hier geblieben. - um ehrlich zu sein aus dem Grund, dass dies der einzige Wandkonvektor war, der nicht aussieht, als würde er aus den 90ern kommen.Er hat kein Gebläse, d.h. die warme Luft steigt einfach nach oben heraus und wärmt den Raum so.Das passt für unsere Räume, ist aber vielleicht nicht für jede Situation empfehlenswert.Wir steuern diesen Wandkonvektor per HomeAssistant/Bewegungsmelder. Das klappt super und der Raum wird auch schnell warm.Die lauten Geräusche macht er, weil sich das Metallgehäuse bei der Wärme ausdehnt und dann andere Teile erstmal hinterherkommen müssen - dann gibt es ein lautes "ZONK". Bei den ersten Malen wundert man sich noch und denkt "HUCH!" aber irgendwann gewöhnt man sich dran. :)Deswegen ein Stern abzug.Sonst klare Kaufempfehlung.

We tried several wall-mounted convector heaters (Dreo, Stiebel Eltron) and stuck with this one – to be honest, because it was the only one that didn't look like it came from the 90s. It doesn't have a fan, meaning the warm air simply rises and heats the room. This works well for our rooms, but it might not be suitable for every situation. We control this wall-mounted convector heater with a Home Assistant/motion detector. It works perfectly, and the room heats up quickly. The loud noises are due to the metal casing expanding when heated, and then other parts have to adjust – resulting in a loud "ZONK." The first few times, you're surprised and think "Whoa!", but you get used to it eventually. :) That's why I'm deducting one star. Otherwise, I highly recommend it.

We are very impressed! The app is very easy to install. The remote control is also very good. Thanks to the wheels and compact size, the oven can easily find a place in any room. It heats up quite quickly. We will buy another one!

Macht seinen Job sehr gut, allerdings lautes Knacken bei Aufheizen und Abkühlen. Wlan Verbindung incl. Alexa sehr einfach. Absolute Kaufempfehlung, habe bereits 3 Geräte im Einsatz.

It does its job very well, however, it makes a loud crackling noise when heating up and cooling down. The Wi-Fi connection, including Alexa integration, is very easy. I highly recommend it; I already have three units in use.

Pedí el calefactor Klarstein Bansin de 2500 vatios con mucha ilusión, ya que su elegante diseño y sus funciones inteligentes me conquistaron de inmediato. Y debo decir: ¡En muchos sentidos, es un producto fantástico que cumple con lo prometido!Lo que más me gustó:Diseño y calidad: El aparato tiene un aspecto simplemente impresionante. El frontal de cristal y sus líneas estilizadas son realmente llamativos. La fabricación es de primera calidad y le da a cualquier habitación un toque moderno al instante.Control inteligente: El control mediante la aplicación es ingenioso y funciona a la perfección. Poder encender el calefactor de camino a casa es una comodidad indispensable.Funcionamiento intuitivo: La pantalla táctil es muy fácil de usar y los distintos modos (especialmente el modo ECO) están muy bien pensados.Por qué lo devuelvo:Ahora bien, el quid de la cuestión: El calefactor es potente, pero simplemente era demasiado para mi habitación. Tengo un edificio antiguo muy diáfano, con techos altos y más de 50 metros cuadrados, que suele ser difícil de calentar.Aunque el Bansin hizo lo posible y sin duda funcionaría de maravilla en habitaciones más pequeñas o en edificios nuevos mejor aislados, en mi caso concreto no logró alcanzar la temperatura confortable que deseaba en ese espacio tan grande. Es perfecto para habitaciones de tamaño normal o como calefacción complementaria, pero para el vestíbulo de mi edificio antiguo, lamentablemente tengo que buscar una solución aún más potente.Conclusión:Es una verdadera lástima, porque devuelvo el aparato con mucha pena. El Klarstein Bansin es un dispositivo de alta calidad, elegante e ingenioso. Para el usuario doméstico medio, es una compra imprescindible. Personalmente, necesito un aparato con aún más potencia para mis necesidades específicas. Sin embargo, ¡fue una gran experiencia y un producto fantástico!

I ordered the Klarstein Bansin 2500-watt heater with great enthusiasm, as its elegant design and smart features immediately won me over. And I must say: In many ways, it's a fantastic product that lives up to its promises! What I liked most: Design and quality: The appliance looks simply stunning. The glass front and sleek lines are truly eye-catching. The build quality is top-notch, instantly giving any room a modern touch. Smart control: The app control is ingenious and works flawlessly. Being able to turn on the heater on my way home is an indispensable convenience. Intuitive operation: The touchscreen is very easy to use, and the various modes (especially the ECO mode) are very well thought out. Why I'm returning it: Now for the crux of the matter: The heater is powerful, but it was simply too much for my room. I have a very open-plan, older building with high ceilings and over 50 square meters, which is usually difficult to heat. Although the Bansin did its best and would undoubtedly work wonderfully in smaller rooms or in newer, better-insulated buildings, in my specific case, it failed to reach the comfortable temperature I desired in such a large space. It's perfect for normal-sized rooms or as supplemental heating, but for the lobby of my older building, I unfortunately have to look for an even more powerful solution. Conclusion: It's a real shame, because I'm returning the unit with great regret. The Klarstein Bansin is a high-quality, elegant, and ingenious device. For the average home user, it's a must-buy. Personally, I need a more powerful unit for my specific needs. However, it was a great experience and a fantastic product!

Il prodotto ahimè è arrivato senza un piedino...Contattato assistenza tramite Amazon, ricevuto immediatamente risposta.Trovo assurdo non abbiano il pezzo di riserva, questo mi è stato detto dall'assistenza.Le loro proposte:Un reso con rimborso totale (mah assurdo)Un reso con sostituzione articolo (nuovamente assurdo)Faccio presente che il reso, la spedizione è a carico dell'acquirente questo dicono le loro linee guidaUltima soluzione uno sconto del 20% sul prezzo d'acquisto, che ho accettato...Ora la stufa è perfetta, molto sottile e funzionale, scalda bene, io l'ho sistemata in un cucinino 4x4 è raggiunge velocemente la temperatura desiderata...Ottimo il telecomando e l'app per programmarla tramite wifi...Che dire... Tutto bene a parte questo piccolo inconveniente che davvero con un magazzino ricambi risolverebbero tutte queste piccole criticità.Consigliata

Unfortunately, the product arrived without a foot... I contacted support via Amazon, received an immediate response. I find it absurd that they don't have the spare part, this is what support told me. Their proposals: A return with a full refund (absurd) A return with an item replacement (again absurd) I would like to point out that the return, shipping is the buyer's responsibility, this is what their guidelines say. Last solution is a 20% discount on the purchase price, which I accepted... Now the stove is perfect, very thin and functional, it heats well, I placed it in a 4x4 kitchenette and it quickly reaches the desired temperature... The remote control and the app for programming it via Wi-Fi are excellent... What can I say... All good apart from this small inconvenience that really with a spare parts warehouse they would solve all these small critical issues. Recommended
