UK model status
Google’s UK range lists the Nest Learning Thermostat, 3rd generation, and Nest Thermostat E. The North American Nest Learning Thermostat, 4th generation, is not a normal UK Heat Link boiler product and is not ranked here.
| Model | Heating and hot water | Installation boundary |
|---|---|---|
| Nest Learning Thermostat, 3rd generation with Heat Link | Compatible relay or OpenTherm heating; compatible on/off cylinder control | Google recommends professional installation because Heat Link uses high-voltage wiring |
| Nest Thermostat E with Heat Link E | Combi-focused heating; it cannot schedule a separate cylinder | Use a qualified installer if the wiring or system is uncertain |
| Nest Learning Thermostat, 4th generation | North American product | Do not use as a UK Heat Link replacement |
Buying decision
Check the boiler interface, hot-water layout, wiring and installer requirements. Do not assume a US Nest product substitutes for a UK/EU Heat Link model.
