Rointe Kyros vs Sygma vs Belize: Which Electric Radiator Is Right for Your Room?
Kyros is thermal fluid technology with integrated WiFi: best for living rooms, open-plan spaces, and rooms in continuous daily use. Sygma is also thermal fluid technology, but the more basic, programmable model in the range, controlled via its own panel with a 24/7 timer rather than built-in WiFi (a Remote control is available as an optional extra): best for bedrooms, home offices, and intermittent-use rooms. Belize is thermal fluid technology with integrated WiFi and IP44 models available: best for bathrooms and damp locations, Zone 2/3 suitable.
If you are specifying Rointe electric radiators for an Irish property, or advising a homeowner on which model to choose, the Kyros, Sygma, and Belize all use the same thermal fluid heating technology and share a ±0.2°C thermostat, but differ in control type (integrated WiFi versus an optional remote), IP rating, and wattage options. This guide covers which Rointe model is right for each room type in an Irish home.

Rointe Kyros: Best for Living Rooms and Open-Plan Spaces
The Kyros is Rointe's flagship model, using the same thermal fluid technology as the rest of the range, but built as the top-tier option with integrated WiFi and app control as standard. The Kyros is the correct specification for:
- Living rooms and sitting rooms: continuous occupancy benefits from stable temperature maintenance and app-based scheduling
- Open-plan kitchen-diners: large volumes benefit from the Kyros's higher wattage options (up to 1,800W) and sustained heat output
- Home-working spaces in regular use: WiFi control and adaptive scheduling suit rooms with a regular daily pattern of occupancy
Kyros wattage range: 600W, 750W, 1,000W, 1,500W, 1,800W. All models: IP24, 24/7 programmer, WiFi ROINTEX control, ±0.2°C thermostat, open window detection.
Rointe Sygma: Best for Bedrooms and Occasional-Use Rooms
The Sygma uses Rointe's thermal fluid technology, the same core heating element as the Kyros and Belize, but is positioned as the more basic, programmable model in the range. Rather than built-in WiFi, control is via the radiator's own mechanical keypad and TFT screen with a 24/7 programmer built in, and a Rointe AIR or BASIC remote control can be added as an optional extra for infrared operation. For rooms where a straightforward, on-radiator programmer is preferable to app control, the Sygma is the right specification:
- Bedrooms: the built-in 24/7 programmer suits a fixed evening schedule without needing WiFi or an app
- Spare rooms and guest rooms: a simple, self-contained programmer is often all that's needed for occasional use
- Home offices with variable occupancy: set a schedule for occupied hours directly on the radiator, or add the optional Remote for quick manual adjustments
Sygma wattage range: 600W, 750W, 1,000W, 1,500W. All models: IP24, 24/7 programmer, ±0.2°C thermostat, open window detection. WiFi is not built in; a Rointe AIR or BASIC remote control is available as an optional extra.
Rointe Belize: The Bathroom Choice
The Belize shares the Kyros's and Sygma's thermal fluid technology and, like the Kyros, includes integrated WiFi as standard. Its critical addition is IP44 water-ingress protection on specific models in the range, making them suitable for bathroom Zone 2/3 installation under IS 10101 requirements. The Belize is the standard Rointe specification for:
- En-suite bathrooms: IP44 models suit Zone 2 installation, and thermal fluid heating is appropriate for a room used briefly and frequently
- Main bathrooms: bathroom heating is one of the most common use cases for electric radiators in Irish homes, particularly in older properties without towel rail connections
- Utility rooms and damp-location spaces: the IP44 rating provides protection in utility and laundry rooms where moisture is present
Important: confirm the IP rating on the specific Belize model, not all Belize units are IP44. EEW branch staff can confirm IP44 availability for specific SKUs. Bathroom zone requirements are covered in how to choose an electric radiator in Ireland.
Which Rointe Model Is Best for Each Room in an Irish Home?
| Room type | Recommended Rointe | Reason | Typical wattage |
|---|---|---|---|
| Living room | Kyros | Continuous use, thermal mass | 1,000 to 1,800W depending on room size |
| Open-plan | Kyros | Large volume, sustained output | 1,500 to 1,800W or 2× units |
| Master bedroom | Sygma | Built-in 24/7 programmer, no WiFi needed | 750W to 1,000W |
| Spare bedroom | Sygma | Simple on-radiator programming for occasional use | 600W to 750W |
| Bathroom | Belize | IP44 water protection required | 600W to 750W |
| Home office | Sygma | Set-and-forget schedule, Remote optional | 1,000W to 1,500W |
| Utility room | Belize | Damp location, IP44 preferred | 600W to 750W |

Frequently Asked Questions
-
What is the main difference between Kyros and Sygma?
Mainly control type, not heating technology. Both the Kyros and Sygma use Rointe's thermal fluid heating element. The Kyros is the more advanced model, with integrated WiFi and app control as standard. The Sygma is the simpler, non-WiFi model, programmed via its own on-radiator panel, with a Remote control available as an optional extra. -
Can I put a Kyros or Sygma in a bathroom?
Only outside the bathroom zones. Kyros and Sygma are IP24, which meets the minimum outside zones. For Zone 2/3, an IP44-rated Belize model is required under IS 10101. -
Do all three ranges have the same controls?
Not quite. All three include a ±0.2°C electronic thermostat, a 24/7 weekly programmer, and open window detection. Kyros and Belize add integrated WiFi and app control as standard. Sygma is controlled via its own panel, with a Rointe AIR or BASIC remote control available as an optional extra rather than built-in WiFi. -
Are all Belize models IP44?
No. IP44 applies to specific models within the Belize range, not all of them. Confirm the IP rating on the exact SKU before installing in a bathroom zone, EEW branch staff can check this for you.
