Rointe Onyx 1250W High Heat Retention Wifi Storage Heater 10 Element

The Rointe Onyx WiFi Storage Heater delivers smart, energy-efficient heating with advanced WiFi Direct connectivity and AI-powered optimisation. Designed for modern homes, it combines precise temperature control, reduced energy consumption, and a sleek contemporary look for comfortable, cost-effective warmth.

More than 55% heat retention after 16 hours: ONYX retains more than 55% of its stored heat even after 16 hours, helping preserve thermal energy for when it is actually needed.

WiFi Direct — no gateway required: The integrated WiFi module connects directly to a compatible 2.4 GHz WiFi router, without requiring an additional gateway, hub or smartbox. Users can control the heater remotely through the Rointe Nexa app, including temperatures, programmes, operating modes and energy consumption.

Smart Charge function that actually works: The Smart Charge function charges the heater at the optimum point within the programmed charging schedule. This allows ONYX to prepare the stored energy required to deliver the desired comfort while helping avoid unnecessary charging and energy use.

Inverter Smart Adaptive technology: The integrated inverter system automatically adjusts the fan speed continuously according to the heating needs of the room. This adaptive operation improves the management of stored energy and provides more stable thermal comfort than a basic fixed-speed fan system.
