Combining classic styling with reliable performance, the Spectrum Inbuilt transforms an unused fireplace into an efficient source of warmth, delivering the cosy ambience and dependable operation that Rinnai gas heaters are renowned for.

Designed to provide both radiant and convection heating, the Spectrum creates a comfortable living environment by delivering direct warmth while circulating heated air throughout the room. With a maximum heat output of 5.2kW, the Spectrum is capable of heating areas up to 75m², making it ideal for living rooms, family spaces and smaller open-plan environments.

The Spectrum Inbuilt is engineered for simplicity and ease of use, featuring three convenient push-button heat settings that allow you to quickly select the level of warmth that suits your comfort needs. A built-in two-speed fan helps distribute heat evenly throughout the room, ensuring efficient performance and improved comfort during colder months.

Available in Beige or Brown finishes, the heater complements both traditional and contemporary interiors while delivering the reliability and durability that have made Rinnai one of Australia's most trusted heating brands.
