    Overview

    Designed with modern living in mind, Rinnai Hot Water Recess Boxes offer a sleek and practical solution for housing your continuous flow hot water system. Perfectly suited for Rinnai Infinity and Infinity B models, these recess boxes allow your hot water unit to be installed within your wall cavity, saving valuable outdoor space and creating a clean, streamlined exterior finish. Whether you're working with brick, rendered, or weatherboard exteriors, these recess boxes are engineered for seamless integration and effortless installation.

    Available in full or semi-recessed configurations, the boxes are constructed from either robust sheet metal or durable, UV-stabilised ABS plastic, ensuring long-lasting performance and weather resistance. They come ready to be painted, allowing homeowners or builders to match the unit with any facade or colour scheme for a discreet and unified appearance.

    Every detail is considered to deliver convenience and versatility. The brick application includes compatibility with standard brick ties, the rendered option comes with offset spacers, and the weatherboard version features a semi-recessed frame. This adaptability makes the Hot Water Recess Box a smart choice for a wide variety of home styles and construction types.

    By recessing your Rinnai Infinity hot water system, you not only preserve your outdoor space but also enhance the aesthetics and practicality of your property. These purpose-built boxes reflect Rinnai's ongoing commitment to innovation and user-friendly design, offering a space-saving, visually integrated solution that complements contemporary homes.
