Frequently asked questions
Which heating systems / boilers are compatible?
Gas & LPG
Hive Thermostats are compatible with most UK gas and LPG central heating systems and our professional installation engineers are trained to work on both.
Oil boilers
Hive Thermostats work with most oil boilers and can replace your existing conventional thermostat or programmer.
However, if you have existing intelligent oil boiler heating controls that modulate your heating, a Hive thermostat will not replace this functionality.
We don't offer pro installation on oil boilers so we recommend contacting an OFTEC-qualified engineer to install the thermostat.
Electric boilers
If your boiler works with a standard room thermostat and / or programmer then a Hive Thermostat can control it. However, the thermostat doesn't work with storage heaters or individual plug-in electric room heaters.
Other systems
Unfortunately our engineers can't install a Hive Thermostat on solid fuel boilers (such as biomass systems or coal) and heat pumps. We are yet to complete our testing on these systems and therefore can’t yet guarantee compatibility.
In the unlikely event that the thermostat cannot be installed in your home, you can receive a full refund for your purchase (this is valid for 14 days from the point you receive the product or the day of your installation).
What types of heating control systems and boilers are incompatible with Hive Active Heating?
Control systems
Honeywell SmartFit Controls: this system, sometimes installed to control gas and LPG boilers, is part of the existing central heating system and isn’t compatible with other external heating controls. Hive Thermostats can’t be installed with it unless the engineer removes the SmartFit controls first including all electrically operated valves.
Vaillant VR 65 Control Centre: this is an external controller fitted to some compatible Vaillant boilers. It’s part of the existing central heating system and isn’t compatible with other external heating controls. Hive Thermostats can’t be installed with it unless the engineer removes the Valliant external controller.
Boilers
Hive Active Heating is compatible with most boilers, but it is incompatible with the following models:
- Worcester Bosch ICC2 - ZWBR 11-37A (GC number: 4710810)
- Worcester Bosch *C*RD 537i (GC number: 4710811)
- Worcester Bosch *C*RD 542i (GC number: 4710812)
- Worcester Bosch Greenstar HE Plus - ZWBR 7-28A (GC number: 4731156)
- Worcester Bosch Greenstar HE Plus - ZWBR 11-35A (GC number: 4731157)
- Worcester Bosch *C* Greenstar 30 HE Plus Combi (GC number: 4731175)
- Worcester Bosch *C* Greenstar 35 HE Plus L Combi (GC number: 4731176)
- Worcester Bosch *C* Greenstar R 30HE Plus (GC number: 4731179)
- Worcester Bosch *C* Greenstar R 35HE Plus (GC number: 4731180)
- Worcester Bosch *C* Greenstar R 40HE Plus (GC number: 4731181)
All other boilers are, to the best of our knowledge, compatible with Hive Thermostats. If you'd like clarification on this, an engineer would be able to tell you. Don’t forget we have a 14-day return policy if you want to change or return your thermostat.
Can I control heat in different rooms or floors?
Yes. If you want your upstairs warmer than your downstairs, or this room cooler than that room, you can set different temperatures in different rooms and/or floors with Hive Multizone.
You’ll need different thermostats for the areas you want to vary the heating in. Just buy your first thermostat (this comes with Hive Hub) for your main heating zone, then upgrade to Hive Multizone. The Hive Multizone kit contains an extra thermostat and receiver allowing you to control the heat in different areas of your home.
To install Hive Multizone you would need an existing multi-zone set up within your home or have the relevant work done in your home. You can find out more about multi-zone heating by clicking here, or you could always book an engineer visit to find out more.
Does the thermostat work with underfloor heating systems?
Hive Thermostats can be used to support wet underfloor heating systems (which provide heat using pipes) but they do not currently support electric underfloor heating systems.
The heat produced from underfloor heating ensures an even distribution of heat in rooms, so it’s one of the most energy-efficient ways to heat your home.
Can I control hot water with the thermostat?
Yes, if you have a conventional heating system (i.e. a separate hot water tank heated by your boiler) you can control your hot water with the thermostat. Hot water can be controlled within the Hive app by selecting Hot Water in the app dashboard.
You can’t control your water temperature with the thermostat but you can turn your hot water on or off, set a schedule or boost it (which turns the hot water on for 1-6 hours).
Hive Hint: You can usually set the temperature of the hot water directly on your tank.
Can I install the thermostat myself?
To install the thermostat, you need to be competent in electrical wiring and DIY. We would recommend finding an experienced local tradesperson.
Where should the thermostat be placed?
Your thermostat will work best when fixed to a wall about 1.5m off the ground, away from heat sources and out of direct sunlight. You can also use the thermostat stand (available separately) to position it on a table or shelf within your home.
Will the Hive Thermostat Mini still work if my WiFi loses connection?
If your internet connection goes down, the thermostat will continue to work and you'll be able to use your thermostat to turn the temperature up and down as normal. Any heating or hot water schedules you've set up previously will also continue to run automatically. However, you won’t be able to control your heating via the app until the internet comes back online.
Does the thermostat work with other Hive devices?
Yes, you can connect your thermostat with other Hive devices using the Hive app – for example you can boost the heating when a Hive Motion Sensor detects movement.
You can also operate your thermostat and other Hive devices with Amazon Alexa, Google Assistant, Apple HomeKit and Siri Shortcuts.
How do I replace my existing Hive Thermostat with a new one?
You can set up your replacement thermostat through the app. Once open, go to the dashboard and select 'Add'. Alternatively, click the top right corner to access the menu. Tap 'Upgrade or Replace' and follow the on-screen instructions.
Can I use my thermostat with Hive Actions?
Yes, your thermostat works with Hive Actions. You can choose from a number of pre-set actions that we know work really well and even create your own.
Can the Hive Thermostat Mini save me energy?
Yes, as you can set schedules to only heat your home when it is occupied. You can also manage your heating using the Hive app so you’re only using the heating when you need to. This is better for the environment and helps saves on your energy bills.
What can I control on the Hive Thermostat Mini device?
We want to make things more flexible for you. On the device, you can set the target temperature and change the modes for the heating and hot water. You can manage your heating using the Hive app wherever you are, including boosting your heating and creating schedules.
Does this product work with voice control?
Yes, this Hive product can be used with voice control such as Amazon Alexa, Google Assistant, Apple HomeKit and Siri Shortcuts.
What devices can I get the Hive app on?
You can get the Hive app on many smartphones, tablets and the Apple Watch. iOS or Android devices must be running an up-to-date operating system.

OpenTherm FAQs
Can I install Hive OpenTherm on a multizone system?
Currently we only support single zones with OpenTherm. If you’re installing Hive Heating on an OpenTherm-compliant plumb zone system, your engineer will have to configure all OTR1 receivers to Standard (Relay) Mode.
How does OpenTherm increase efficiency?
OpenTherm is a communication protocol used by modern condensing boilers and OpenTherm-enabled controls. It allows boilers and controls to share more information via load compensation (or modulation), which helps improve efficiency.
Modulation through OpenTherm allows the boiler to reduce power when only a little heat is needed. This makes sure the Hive thermostat heats the radiators to the desired temperature and then lowers the boiler’s power output. This stops the temperature going too high and keeps the heat balanced in the home.
This intelligent power switching based on the home’s heat demand allows you to set and forget the system. You won’t need to manually adjust the boiler’s flow temperature for different seasons. And as the boiler changes its power output to match demand, you’ll be able to use less energy and save more.
I don’t know if my boiler supports OpenTherm. What should I do?
Our OpenTherm- compliant receiver can be installed in either Standard (Relay) Mode or OpenTherm Mode, so don’t worry - your engineer will check and install the best one for you. Hive can work with most systems as long as they can be run using external controls.
What other benefits does OpenTherm control have over Standard (Relay) Mode?
More energy-efficient - OpenTherm allows modulating control – this allows the boiler to adjust its output more accurately, based on heat demand. This optimises energy usage and can even reduce gas emissions by up to 12%
Reduced wear and tear - As the boiler adjust the output more accurately, there are fewer on/off cycles which helps to increase the boiler’s lifespan as there is less stress on the system
Lower gas consumption - As the boiler adjusts the water temperature as needed, the temperature change is less dramatic, so less energy is needed to heat the water to the desired temperature
Comfortable room temperature - OpenTherm maintains a steady heat output, preventing overheating or underheating
Will my radiators be cooler when using OpenTherm?
It really depends on how much heat the home requires. When you set a target temperature on your Hive thermostat, our controls will assess how big the gap is between the actual room temperature and the target temperature you’ve set.
When there’s a large gap between the target and actual room temperatures, your Hive thermostat requests a high-water temperature, so the radiators will be warmer. As the room temperature nears the target, the requested water temperature decreases. During this time, radiators may feel cooler, but the room temperature will be approaching the target, which is what matters.
It’s also important to point out that the boiler will run for longer periods, but it will be producing water at lower temperatures, resulting in less energy being used and maximising the time spent in the higher efficiency condensing mode.
One of the main benefits of OpenTherm modulation is more stable and accurate control of the room temperature.
