We have become aware of an issue that is impacting some 3rd Gen Nest Learning Thermostat Heat Links in the UK and other European countries. The Heat Link device allows our thermostats to communicate with boiler systems and control the heating (and sometimes hot water) for homes in those regions.
We’re reaching out to users who we think may have this issue to replace their Heat Links at no cost, regardless of their thermostat’s warranty status. Customers in the UK can simply pick a date to have a professional supply and install a replacement device through our partner BOXT, a leading heating maintenance provider. For other customers who may be experiencing this issue, you can select an installer of your choice to install a replacement device and Google will reimburse the repair cost. As a reminder, we always recommend having any issues seen by a professional.
We apologise if you have been impacted by this issue. If you have questions or need additional guidance, please reach out to Google customer support via the Help Center.
