In short
Zoned heating with Wiser replaces radiator heads with connected thermostatic heads and adds room thermostats where needed. Each room has its own temperature and schedule, and the hub only fires the boiler or heat pump when a zone calls for heat. Under UNE-EN ISO 52120-1, moving to this level of control saves a home 12 % on heating.
What is installed for each heating type
| Heating | Devices | What it achieves |
|---|---|---|
| Water radiators with boiler | Thermostatic heads, thermostat and boiler control | Each radiator at its temperature and boiler on only when needed. |
| Underfloor heating | Room thermostats and zone actuator control | Each floor circuit with its temperature and schedule. |
| Heat pump | Thermostats and unit control | Per-room schedules and setpoints. |
The biggest-saving functions
- Per-room schedules: bedrooms mild at night, living room in the evening.
- Away mode from your phone when leaving home.
- Open-window detection to shut the radiator.
- Temperature history to fine-tune the installation.
