The Hive Nano 3 thermostat is designed for controlling heating in homes with combi boilers using OpenTherm technology, which helps communicate precisely with your boiler to save energy and maintain a steady temperature. This can lead to up to 12% lower gas usage, which means potential savings on heating bills and a longer boiler lifespan. It connects via Wi-Fi through the new Nano 3 Hub, which is easy to set up and offers reliable performance without lots of cables. You can program heating and hot water schedules with up to six daily time slots, giving you good flexibility to match your routine.

The thermostat includes smart features like geolocation to adjust heating when you leave or come back home, frost protection to prevent pipe freezing, and a holiday mode so your house is warm when you return from a trip. The user interface is a simple touch screen with button controls and clear graphical display, making it straightforward to use even if you’re not tech-savvy. One nice bonus is the included 50% discount on Hive Plus, a service plan that can help you save more energy.

It is specifically built for combi boilers using OpenTherm, so it might not work with other heating systems. Some users might also find the initial setup of the hub and device slightly involved if they aren’t comfortable with smart home gadgets.

Smart features like geolocation help save energy by adjusting heating based on whether you’re home, and Holiday Mode keeps your system efficient while you’re away. The touchscreen interface and voice control make operating the thermostat simple and modern, although the touchscreen is relatively basic compared to some higher-end models. Installation requires hardwiring to your heating system, so it may be best suited for those comfortable with some home wiring or willing to hire a professional. Energy efficiency is supported through the scheduling and boosting options, plus automatic frost protection helps prevent damage during cold weather. The Hive app adds convenience for remote control and monitoring.

It’s designed specifically for conventional boilers, so it may not work with all heating systems. Also, while it includes a 50% discounted annual plan for extra energy savings, full access to advanced features might require a subscription.
