Rointe ONYX Wi-Fi High Heat Retention Storage Heaters

Discover the Rointe ONYX Wi-Fi High Heat Retention Storage Heater range at Alert Electrical Wholesalers – a new generation of intelligent electric storage heating designed to combine the advantages of off-peak electricity with advanced heat retention, smart controls and modern heating technology.

The Rointe ONYX takes the traditional storage heater concept and brings it firmly into the smart-home era. Its high heat retention mineral core stores thermal energy for use later in the day, while intelligent charging, fan-assisted heat delivery and Inverter Smart Adaptive Technology help manage how that stored energy is used.

With built-in Wi-Fi Direct, control through the Rointe NEXA app, AI-assisted heating functions and multiple programmable modes, ONYX provides homeowners, landlords and property professionals with significantly more control than a conventional storage heater.

What Is a High Heat Retention Storage Heater?

Storage heaters are designed to take advantage of electricity during designated charging periods, commonly associated with off-peak electricity tariffs, store that energy as heat and release it when required.

The key difference with a High Heat Retention (HHR) storage heater is its ability to retain a greater proportion of stored thermal energy for later use.

Rointe ONYX uses a high heat retention mineral core combined with effective insulation to keep stored heat inside the appliance until it is needed.

This makes ONYX particularly attractive for properties using suitable off-peak electricity tariffs where homeowners want to maximise lower-cost charging periods while maintaining comfortable temperatures throughout the day.

High Heat Retention for Longer-Lasting Warmth

At the centre of the Rointe ONYX is its specially designed thermal storage system.

Rointe's mineral core technology and insulation allow the heater to retain a substantial proportion of its stored heat many hours after charging.

Rather than allowing stored warmth to escape unnecessarily, the heater manages the release of heat according to the room's heating requirements.

This provides several important benefits:

• More controlled release of stored heat
• Reduced unnecessary heat loss
• Greater availability of stored warmth later in the day
• Reduced dependence on daytime top-up heating
• More consistent room temperatures
• Better utilisation of suitable off-peak electricity tariffs

The result is a modern storage heater designed around both comfort and energy management.

Smart Dynamic Charging

Traditional storage heaters can sometimes store more heat than is actually required.

Rointe ONYX uses automatic intelligent charge control to calculate the amount of energy that needs to be stored for the following heating period.

Rather than simply charging the thermal core to maximum capacity every night, the system can manage charging according to heating requirements.

This intelligent approach helps reduce unnecessary electricity consumption while ensuring sufficient stored energy is available when required.

Inverter Smart Adaptive Technology

One of the technologies that distinguishes Rointe ONYX from conventional storage heating is Inverter Smart Adaptive Technology.

The system continuously adapts the heater's operation according to the thermal requirements of the room.

Instead of relying solely on simple on/off heating cycles, inverter control allows the heater to regulate its operation more intelligently as the room approaches its target temperature.

This helps provide:

• More stable room temperatures
• Controlled heat delivery
• Improved energy management
• Reduced unnecessary power consumption
• Greater thermal comfort

Rointe states that its Inverter Smart Adaptive technology can reduce stabilisation power by up to 80%.

Wi-Fi Direct – No Additional Gateway Required

Rointe ONYX features Wi-Fi Direct technology built into the heater.

The integrated Wi-Fi module allows the heater to connect directly to a compatible router without requiring an additional gateway or smart-home hub.

Once connected, compatible functions can be managed remotely through the Rointe NEXA app.

This simplifies the smart-heating installation while giving users control of their heating from virtually anywhere with an internet connection.

Control Your Heating with the Rointe NEXA App

The Rointe NEXA app turns a smartphone into a central control point for compatible Rointe heating products.

Users can remotely manage their ONYX heaters and monitor heating performance from the app.

Available functionality includes the ability to:

• Adjust temperatures remotely
• Turn heating on and off
• Create heating programmes
• Monitor electricity consumption
• Review energy usage
• Manage heating costs
• Lock individual heaters remotely
• Create heating environments and scenarios
• Manage multiple compatible Rointe products

This makes ONYX particularly useful for households where heating schedules change throughout the week.

AI-Assisted Heating

Rointe ONYX also incorporates an AI Heating System designed to learn from heating behaviour and provide recommendations that can improve comfort and optimise energy consumption.

Combined with intelligent charging, Wi-Fi connectivity and inverter control, this gives ONYX a level of automation far beyond that associated with older manual storage heaters.

Integrated Energy Consumption Monitoring

Understanding how much energy a heater actually consumes can make it easier to manage electricity costs.

ONYX incorporates Rointe's True Real Power consumption meter, which collects energy-consumption information and communicates it to the Rointe NEXA app.

This gives users greater visibility over their electric heating and can help them make more informed decisions about temperatures, programmes and operating times.

24/7 Programmable Electric Heating

Rointe ONYX provides extensive programming options to adapt heating around different lifestyles.

Features include:

• 24/7 programming
• Seven-day programmable timer
• Home All Day mode
• Out All Day mode
• Frost Protection
• Away mode
• Boost mode
• Setback mode
• Holiday settings
• Countdown function
• Editable preset programmes
• Automatic charge control

These controls allow heating to be adapted around working patterns, weekends, holidays and changes in occupancy.

Open Window Detection

Leaving a window open while heating a room can result in unnecessary energy consumption.

Rointe ONYX includes an Open Window function designed to detect relevant sudden temperature changes and adjust operation accordingly.

This works alongside the heater's other energy-management features to help reduce avoidable electricity consumption.

Limited Mode for Landlords & Managed Properties

ONYX isn't limited to owner-occupied homes.

Rointe's Limited Mode allows a minimum and maximum temperature range to be established and protected by a password.

This can be particularly useful for:

• Rental properties
• Student accommodation
• Holiday lets
• Airbnb properties
• Hotels and guest accommodation
• Schools
• Residential developments
• Supported and managed accommodation

Occupants can still adjust the temperature within the permitted range while property managers can prevent excessive settings or unauthorised changes to the heater configuration.

Ideal for Replacing Older Storage Heaters

The Rointe ONYX can be particularly attractive when upgrading an older electric storage heating system.

It supports single and dual-feed configurations, providing additional flexibility when considering existing off-peak electrical circuits or a new installation.

This can make ONYX a practical option for upgrading storage heating in:

• Flats and apartments
• Electric-only homes
• Rental properties
• Social housing
• Retirement properties
• Holiday accommodation
• Residential developments
• Properties without a gas supply

Installation requirements should always be assessed by a suitably qualified electrical professional.

Five Sizes to Suit Different Rooms

The Rointe ONYX range is available across five heater sizes, allowing installers to select an appropriate model according to the heating requirements of the room.

The range includes models with charging powers of approximately:

• 1,020W
• 1,560W
• 2,220W
• 2,760W
• 3,300W

Physical dimensions and stored-heat output vary between models, allowing ONYX to provide solutions for different room sizes and heat-loss requirements.

Correct heater sizing is important. Room dimensions, insulation, glazing, external walls, ceiling height and other heat-loss factors should be considered before selecting a model.

Renewable Energy Compatible Electric Heating

Electric heating can increasingly work alongside electricity generated from renewable sources.

Rointe states that its electric heating products are compatible with renewable energy systems including solar photovoltaic generation.

For homes moving towards greater electrification, this makes intelligent electric heating particularly relevant alongside technologies such as:
