Hot Stuff by Valentina Karga

Bringing fire back into the public realm, Berlin-based artist and architect Valentina Karga introduces HOT STUFF in the university city of Witten, Germany. Composed of two rocket stoves and a mass heater, the installation is the first of its kind to be built in a shared open space, offering the possibility to spend more time outdoors in the winter, while keeping cosy and warm.

A Rocket Mass Heater is a very efficient kind of heater which uses very little fuel (wood) for a maximum output. With the rise of open source knowledge and the online DIY scene, rocket mass heaters became an internet phenomenon. Locals were invited to learn and to experiment together with the making of such an heater in Witten’s public space. A video tutorial of ‘how to build a rocket mass heater for public space’ is indispensable part of the concept, in order to freely share the knowledge of this innovation. Moreover, together with the participants they produced self-made ceramic tiles using a Japanese technique to create patterns with colored clay, that will cover the top surface of the sculpture.
The public sculpture has been produced in collaboration with architects Mascha Fehse and Sébastien Tripod, as a part of the Urban School Ruhr (USR), an educational program by Open Raumlabor University commissioned by Urbane Künste Ruhr.

The artist believes that is important to negotiate what is allowed in public space, claiming back our ‘right to the city’. Sitting in a sofa and cooking are activities, which belong mostly to the sphere of private life, to the private household. Transferring them in public can shape a new concept of the household, a productive unit that is more socially engaged and diffused to its context (the urban space), deconstructing the modernistic idea of the household as a secluded, private unit of consumption. In a way, HOT STUFF is a critical and shared public infrastructure, disguised as artwork.
