Joule Group is a forward-thinking company dedicated to developing sustainable and efficient energy solutions. With a strong track record in heating and ventilation technology, Joule sought to expand their portfolio with a new, innovative solution tailored specifically for the growing demand in all-electric, indoor climate systems.
BEN Heat pump
The ambition was clear: to create a compact, high-performance indoor heat pump that would not only excel technically, but also provide an engaging user experience and design. This is where Helder came in and took on the challenge of designing the housing of the product that would become BEN.

Concept & design language
We began the BEN project with a comprehensive concept phase, deliberately defining a distinctive design language that aligns with Joule’s brand vision. Our team explored a wide range of shapes—favoring clean, minimal lines that convey both modernity and technological sophistication. To ensure the product fits seamlessly into today’s interiors, we introduced rounded edges and textures that soften its overall presence. Throughout the process, our goal was to make BEN look both high-end and approachable, setting a new benchmark for indoor heat pump aesthetics.
Modular versatility for different applications
A cornerstone of BEN’s design is modularity: each heat pump is built from components that can be configured for various installation scenarios – new build, renovation, hybrid, or fully electric systems. The Dual‑Air system intelligently switches between ventilated airflow and outdoor air, delivering a modulating thermal output from 1 to 5 kW to suit homes of different sizes. This adaptability, combined with a plug‑and‑play 190 L hot‑water tank and flexible electrical options, makes BEN a universal solution.
Full scale prototyping
To validate and refine BEN’s modular architecture and usability, we built a series of non-functional prototypes throughout the design process. These full-scale models allowed us to rigorously test how components fit together, how easily modules could be assembled and how the overall system would perform in various spatial configurations. We evaluated key user interactions – like access to filters and connection points – to ensure intuitive installation and servicing. These mock-ups also served as an important tool for reviewing colors, finishes, and material transitions in real-life settings, helping us fine-tune the visual and tactile qualities of BEN.
