Hear It Before You Buy It – The Virtual Sound Experience for Heat Pumps.

Heat pumps make noise – a common purchase concern. Vaillant created the Soundbox to address it. Built by Bright Global as a high-performance, multi-language PWA.

    The App in Numbers

    Technical headline figures for the Vaillant Soundbox.

    A Digital Experience That Solves a Real Purchase Barrier.

    Sometimes the most valuable digital investment is not a website or a shop, but a precisely crafted tool that addresses a concrete purchase barrier. If you have a problem like this – talk to us.

    20+

    heat pump product families covered – each with approximately 6 model variants selectable in the simulator.

  • < 2 sec.

    app load time – a significant improvement over the predecessor tool which regularly lost users before the experience even started.

  • Multi‑language

    The Soundbox supports multiple languages and can be independently configured by local sales organisations for their market.

  • Offline‑ready

    As a Progressive Web App, the Soundbox works without an internet connection – ideal for use during in-person customer conversations.

  • What Bright Global Technically Delivered

    Five core contributions to the Vaillant Soundbox – all on the implementation side.

    • React Frontend Development

      Complete development of the web app in React – from architecture to production readiness, optimised for speed, reliability, and a frictionless user experience.

    • Performance Optimisation

      Critical optimisation of app load time to under 2 seconds – a decisive factor, since the predecessor tool was too slow to retain users before the experience began.

    • Multi-Language Implementation

      Technical implementation of multi-language support, enabling the Soundbox to be available in the local language across Vaillant’s various markets.

    • Offline Capability

      Implementation as a Progressive Web App with offline support – the app works without an internet connection, making it ideal for use during in-person customer visits.

    • Configuration Tool for Sales Organisations

      Development of a configuration tool enabling local Vaillant sales organisations to independently customise the app for their market – without developer involvement.

    • Collaboration with Bejond

      Close collaboration with Bejond as the leading project partner – Bright Global delivered the technical implementation, Bejond led the concept and project management.

    Why the Soundbox Exists – and What It Does

    Three chapters: the purchase concern, the app itself, and what Bright Global specifically contributed.

    The Problem: Heat Pump Noise as a Purchase Barrier

    Heat pumps are the future of home heating – but their acceptance suffers from a simple fact: they produce operational noise, and prospective buyers cannot form an accurate picture of it before purchase. This created concerns rooted not in fact but in uncertainty. Vaillant wanted to dissolve that uncertainty – with a digital tool that makes the real sound of different models at different distances experienceable before a purchasing decision is made.

    The App: Realistic Simulation, Easy to Use

    The Vaillant Soundbox is a web-based Progressive Web App that guides users through a virtual simulation of heat pump sound. They select a model from over 20 product families, set the virtual distance to the unit, and hear the realistic sound – in real time, in the browser, without installation. The app supports multiple languages and can be independently configured by local Vaillant sales organisations for their market. It also works offline, making it an effective tool for sales representatives and installers in customer conversations.

    Bright Global’s Contribution: Frontend Excellence as Implementation Partner

    The Soundbox was developed in close collaboration between Bejond (project lead) and Bright Global (frontend implementation). Bright Global was responsible for the complete technical realisation of the web app: the performant React frontend, the critical performance optimisation to sub-2-second load time, multi-language implementation, PWA capabilities for offline use, and the configuration tool for local sales organisations. The result is an app that feels as simple as a consumer product but carries the technical depth of an enterprise-grade engineering project.
