The Onyx High Heat Retention storage heater from Rointe combines advanced design, intelligent connectivity and real energy savings, delivering efficient, comfortable, and smart heating for modern homes.
High heat retention
Rointe states that Onyx, which is SAP-accredited, offers the highest heat retention on the market, resulting in a more efficient and smarter home. The company notes that the heater retains over 55.3% of its stored heat even after 16 hours, as verified by independent laboratory tests.
Charging only what’s necessary
Smart charging allows the Onyx storage heater to charge more intelligently, instead of simply heating throughout the entire off-peak tariff period. With this mode activated, the heater uses an advanced algorithm to calculate how much heat it needs for the following day and when it should start charging to reach that level on time.
By charging later, only when necessary, Onyx minimises heat loss and reduces unnecessary energy use. Smart charging means the heater never charges more than necessary, never charges earlier than necessary, and always aims to reduce heat loss and improve efficiency, automatically.
Connectivity: goodbye to gateways
With Wi-Fi Direct built in, ONYX connects directly to the user’s home router, enabling seamless data transmission and smart control without the need for external gateways or additional hardware, making installation quicker, easier, and more convenient.
Smart adaptive technology: stable temperature
With Rointe Smart Adaptive technology, Onyx maintains a stable temperature without constant cycles. The system provides consistent heat, improves comfort, and significantly reduces unnecessary energy waste.
Precise control: visual display
Thanks to its visual and touch panel, you can view the charge percentage, selected temperature, schedules and operating modes at all times in a practical and intuitive way, giving you complete control over your heating and making it easier to adapt comfort levels to your daily routine and lifestyle.
Aesthetically attractive
Onyx is designed to fit into any room thanks to its elegant and attractive design, making it the ideal solution for homes that need efficient heating without compromising on style, comfort or interior aesthetics.
Helps improve EPC ratings
Thanks to its high heat retention and smart energy management, Onyx helps transform electric heating into a more efficient system. It’s designed to align with modern UK EPC requirements for rental and sale properties.
