This project aims to create a proof of concept to evaluate the potential value of implementing a heat recovery system for Quooker in the kitchen context. In response to the global goal of achieving net-zero CO2 emissions by 2050, reducing energy loss has become a shared priority. Heat recovery systems can significantly decrease energy consumption, leading to economic and sustainable benefits. In collaboration with Quooker B.V., this project assesses the feasibility and impact of integrating such a system in kitchen environments. The evaluation follows a triple diamond approach, consisting of four stages: discover, define, develop, and deliver. During the discover phase, extensive research is conducted on kitchen contexts, user behavior, existing heat recovery systems, and the characteristics of current kitchen setups. The define phase involves exploring various design directions, identifying potential hazards, and selecting a single promising direction for further development. In the development phase, two design principles are prototyped and tested to determine which one offers the optimal heat recovery rate relative to its initial cost and carbon footprint. The deliver phase focuses on final testing, where the developed concept is evaluated for efficiency during typical kitchen activities, such as draining water after cooking and using the dishwasher. The results are analyzed over a 10-year period of daily use. The project concludes with an assessment of the final concept’s viability, feasibility, and desirability. Recommendations for further research and potential hazards associated with the implementation of
the heat recovery system for Quooker are provided.
