DESIGN NAME: Sauna Habits
PRIMARY FUNCTION: Stove
INSPIRATION: In the background research, the most interesting aspects for me were the genuine experience and the cultural meaning of Finnish sauna. The name Sauna Habits means the approach to look into their culture and habits, slow living, rituals, social life, and also the mindfulness inside a sauna.
UNIQUE PROPERTIES / PROJECT DESCRIPTION: According to different sources, traditional sauna stoves have one of the highest emission factors among residential heating appliances. The suggested solution aims to achieve a more sustainable way of taking sauna without losing the traditional experience of wood burning stoves.
OPERATION / FLOW / INTERACTION: The inner structure of the stove makes the airflow circulate inside to provide a better heat exchange, reduce the waste of heat and effectively burn combustible gases and particulates. The core is made of fireproof concrete. The material choice was based on its capability to resist temperatures high enough to achieve almost total combustion of wood. The properties of the concrete to accumulate and radiate heat for a long time allow reducing wood consumption.
PROJECT DURATION AND LOCATION: The project started in January 2017 in Helsinki. The prototype was finished in August 2017 and exhibited in the National Museum of Finland in September 2017 as part of Helsinki Design Week. In November 2017 it was exhibited in the Global Grad Show in Dubai as part of Dubai Design Week.
FITS BEST INTO CATEGORY: Home Appliances Design

PRODUCTION / REALIZATION TECHNOLOGY: The core of the stove prototype was cast out of fireproof concrete. Moulds for casting were made with a CNC machine out of polystyrene foam. For producing the inner structure parts of the prototype, different techniques of processing steel were used e.g welding, cutting etc.
SPECIFICATIONS / TECHNICAL PROPERTIES: 490 x 490 x 840 mm

RESEARCH ABSTRACT: The main research objectives are addressing the emission issues of wood burning sauna stoves. Their efficiency is low and the flue gas temperature is high. In a typical stove operation, the fuel gasification is fast and the supply of air is clearly insufficient, causing incomplete combustion. In addition to this, the wood consumption is significant due to the constant feeding during the heating process and the actual sauna taking.
CHALLENGE: The biggest challenge of prototyping was the complex concrete casting process, which included 3d modeling and milling of styrofoam moulds, preparation of all pieces, actual fireproof concrete casting, opening the moulds and finishing the surface.
