Central Heating Zones

Adding another thermostat doesn’t automatically create a new heating zone. For zoned heating to work, your home needs to already be set up for it. If it isn’t, Hive Radiator Valves are a great alternative for controlling the temperature of each room individually.

What is a central heating zone?

Central heating zones divide your home into separate areas, each with its own heating control. This means you can manage each area independently and only heat the spaces you’re using, rather than warming the whole house.

Each zone usually includes:

• A thermostat – sets and controls the temperature for that area
• A receiver (or controller) – communicates with the boiler to switch heating on or off for that zone
• A defined part of the home – such as upstairs, downstairs, an extension, or a group of rooms

Zoning is one of the most efficient ways to manage heating. It can help balance comfort and energy use, for example:

• Keeping living spaces warm while bedrooms stay cooler during the day
• Heating downstairs while you're working from home, with the upstairs heating turned off

Common zone setups include upstairs/downstairs or living areas/bedrooms. To use Hive in each zone, each zone needs its own Hive thermostat and receiver, all connected through a single Hive Hub.

How zoned systems work

Zoned heating needs more than just smart controls. Behind the scenes, it relies on separate plumbing components—usually zone valves. These valves direct hot water to different areas of your home so each zone can heat independently.

This means:

• You can’t create a new zone simply by adding another thermostat
• Your heating system must already be physically set up to support multiple zones

Creating new zones where the plumbing isn’t already in place can involve costly and disruptive work, such as lifting flooring and installing extra valves. For this reason, zoning is usually added when a home is built or during major renovation work.

Using Hive with zoned heating

Hive supports multi‑zone heating systems—as long as the zones already exist.

If you’re unsure whether your home has heating zones:

• Check your current heating controls
• Or speak to a qualified heating engineer

If you want zoned heating and don’t already have it, additional plumbing may be needed.

Hive Radiator Valves – a flexible alternative to zoned heating

For homes without existing heating zones, Hive Radiator Valves offer an easy and cost‑effective alternative.

Key benefits:

• Room‑by‑room temperature control
• No plumbing changes needed
• Usually simple to install
• No engineer visit needed in most cases
• Ability to set individual schedules for each room
• Improved comfort while helping manage heating costs

For full room‑by‑room control

For the best experience, consider replacing most (or all) standard TRVs with Hive Radiator Valves. Just note that many homes have at least one radiator without a TRV—often in the room with the main thermostat or on towel radiators.

Quick summary

• Heating zones need specific plumbing
• Adding thermostats alone won’t create new zones
• Hive works with any existing zoned system (with no limit on the number of zones)
• For homes without zones, Hive Radiator Valves are the best alternative

Installation note

If you’re installing a Hive thermostat on an OpenTherm compliant zoned system, all OTR1 receivers must be set to Standard (Relay) Mode. This is position two on the switch inside the OTR1. For full details, please refer to the installation guide.
