Home heating control that aims to reduce waste while keeping rooms comfortable. Commuters and busy households benefit from remote scheduling and frost protection. Is the Hive Thermostat the right upgrade for a home with a combi boiler?

⚡ At a Glance
  • Heating Control: OpenTherm-enabled modulation for more consistent room temperatures and improved efficiency
  • Best for: Owners of combi boilers who want remote control and scheduled heating
  • Not ideal for: Homes with non-combi boilers or systems that do not support OpenTherm

OpenTherm allows precise communication between heating controls and combi boilers. The Nano 3 Hub adds Wi-Fi connectivity and a dual-core processor for reliable performance across multiple Hive devices.


Lower fuel use - Thanks to OpenTherm control

OpenTherm tells heating controls and combi boilers exactly how much heat the home requires, allowing continuous modulation rather than simple on/off cycling. The description notes potential efficiency gains, including lower gas consumption and more consistent room temperatures.

Reduced gas use and steadier warmth make heating bills more predictable, and boiler strain is reduced which supports longer equipment life.

Reliable remote access - With the Nano 3 Hub and Wi-Fi

Nano 3 Hub connects Hive devices to the internet using onboard Wi-Fi and a dual-core processor designed for fast, stable performance on larger networks. The hub removes the need for extra cables and improves responsiveness for app commands.

Quick app control and dependable connections mean homes can be warmed before arrival and schedules remain accurate even on busy networks.

Practical schedules and protections - With timed slots, boost and frost prevention

Heating and hot water schedules can be set up to six daily time slots, plus a boost function that runs for up to six hours. Automatic frost protection monitors conditions to help prevent frozen pipes.

Flexible daily routines and timed boosts suit varied lifestyles, while frost protection reduces the risk of winter damage during absences.
