Wind heater / Campanula hanger

We'd like design a heater which could integrate in the environment. This product was the use of water battery and combined campanula, we just added water for driving the heater, did not need to spend excessive amount of power to replace the traditional methods. The campanula was hanging close to the windows and used thermal convection to warm the space. A symbol of the warm wind blowing, through the principle of thermal convection, so that the indoor temperature to keep warm, cold wind does not cost a lot can also be warm through.
