Heatmiser neoFlo Smart Radiator Thermostat
The Heatmiser neoFlo Smart Radiator Thermostat brings intelligent room-by-room control to compatible radiator systems. It combines quiet operation, precise temperature regulation and long battery life within the wider Heatmiser neo ecosystem.
Use neoFlo as a stand-alone radiator thermostat for simple local control. Alternatively, pair it with the Heatmiser neoHub G3 to unlock app control, advanced scheduling and smart home features.
Furthermore, neoFlo can work alongside a Heatmiser RF Switch when radiator zones need to call for heat from the boiler or another compatible heat source. Therefore, it can form part of a more complete smart heating solution.
Its hybrid control technology combines electronic control with thermostatic regulation. As a result, neoFlo delivers stable room temperatures while maintaining exceptionally quiet operation and an expected battery life of around five to six years.
Why Choose the Heatmiser neoFlo?
Room-by-Room Radiator Control
neoFlo allows individual radiators to operate as separate heating zones. Therefore, different rooms can maintain different temperatures and schedules.
Stand-Alone Operation
The thermostat works independently without a neoHub. Consequently, installers can commission and use neoFlo immediately for local radiator control.
App Control with neoHub G3
Pair neoFlo with a Heatmiser neoHub G3 to access remote control through the neoApp. Furthermore, users can manage advanced schedules and heating settings from their phone.
Smart Heat Demand
Add a compatible Heatmiser RF Switch when neoFlo needs to call for heat from the boiler or other heat source. Therefore, individual radiator rooms can actively request heating when required.
Quiet Operation
Heatmiser designed neoFlo for virtually silent everyday operation. As a result, it works particularly well in bedrooms, offices and other quiet spaces.
Long Battery Life
Hybrid technology helps neoFlo achieve approximately 5 to 6 years of battery life under typical operating conditions. Therefore, maintenance requirements remain low.

What Is the Heatmiser neoFlo?
The Heatmiser neoFlo is a smart thermostatic radiator head designed to control the heat output from a compatible radiator.
It replaces the existing thermostatic head on suitable valve bodies. Therefore, users can gain electronic temperature control without replacing the complete radiator.
neoFlo can operate independently for basic room control. However, connecting it to a neoHub G3 adds app control and advanced smart heating features.
This flexibility makes neoFlo suitable for both simple single-room upgrades and complete multi-zone smart heating systems.
Smart Room-by-Room Heating
Not every room needs heat at the same time.
For example, bedrooms may need more heat during mornings and evenings. Meanwhile, a home office may only require heating during working hours.
neoFlo allows each radiator to respond independently.
Therefore, users can create different temperatures and schedules across individual rooms. This can improve comfort while reducing unnecessary heating.
Typical zones can include:
- Living rooms
- Bedrooms
- Home offices
- Kitchens
- Guest rooms
- Conservatories
- Apartments
- Hotel bedrooms
- Studies
- Dining rooms
Stand-Alone Radiator Control
A neoHub is not required for basic operation.
neoFlo can work independently using its built-in controls. Users can adjust the temperature directly from the setting wheel and use basic scheduling without connecting to the Heatmiser smart network.
Therefore, homeowners can begin with one or more neoFlo units and expand their system later.
This provides a flexible upgrade path without requiring the complete smart heating system from day one.
App Control with neoHub G3
Connecting neoFlo to the Heatmiser neoHub G3 unlocks the full smart control experience.
Users can manage compatible radiator zones through the IMI Heatmiser neoApp.
Additional functions include:
- Advanced schedules
- Remote temperature control
- Temperature hold
- Holiday mode
- Pre-heat
- Open window sensitivity adjustment
- Temperature offset adjustment
- Heating history
- Smart Profiles
- Multi-location control
- Multi-user access
Importantly, neoFlo is compatible with neoHub G3 only. It does not work with neoHub G1 or G2.
neoFlo with RF Switch
Controlling an individual radiator does not automatically tell the boiler to start.
Therefore, Heatmiser offers a fuller heating solution using:
- neoFlo
- neoHub G3
- RF Switch
In this arrangement, neoFlo can request heat through the wider Heatmiser system. The RF Switch then connects to the boiler or other compatible heat source.
As a result, a radiator zone can demand heat when its temperature falls below the set point.
The RF Switch should be installed by a suitably qualified installer.
Open Window Detection
Heating a room with an open window wastes energy.
neoFlo can detect a rapid temperature drop associated with an open window. If the room temperature falls by approximately 2°C within two minutes, the valve closes for 30 minutes.
Therefore, the radiator stops heating unnecessarily while cold air enters the room.
After the period ends, neoFlo returns to its previous operating mode.
When connected to neoHub G3, users can also adjust open window sensitivity through the neoApp.
Simple Time Scheduling
neoFlo can create basic heating schedules even without a neoHub.
Users can set up to four heating periods per day directly on the unit. Therefore, the radiator can automatically move between different temperature settings throughout the day.
For more advanced schedules, connect neoFlo to neoHub G3 and use the Heatmiser neoApp.
Boost Mode
Sometimes a room needs extra heat quickly.
Boost mode fully opens the radiator valve for 30 minutes. Consequently, the radiator can provide maximum available heat during the boost period.
After 30 minutes, neoFlo automatically returns to its previous schedule or operating mode.
Users can also cancel Boost early if required.
Frost Protection
neoFlo includes automatic frost protection.
If the room temperature falls below approximately 5°C, the thermostat opens the radiator valve to help protect against freezing conditions.
Therefore, the feature can provide useful protection in rooms that remain unoccupied or operate at lower temperatures.
Valve Protection Against Limescale
Radiator valves can become stiff if they remain stationary for long periods.
neoFlo automatically exercises the valve approximately once per month. This movement helps prevent limescale or deposits from affecting valve operation.
As a result, the radiator valve remains more likely to operate correctly when heating demand returns.
Adaptive Thermal Balancing
Uneven radiator flow can cause some rooms to heat faster than others.
neoFlo includes adaptive thermal balancing functionality. Therefore, it can help regulate radiator flow and support more even heating across suitable systems.
For more advanced hydraulic balancing, Heatmiser also references compatible IMI Heimeier valve solutions.
Long Battery Life
neoFlo uses four AA batteries.
Its hybrid operating technology helps minimise electrical consumption. Consequently, expected battery life can reach approximately five to six years.
A low battery indicator appears when replacement becomes necessary.
Therefore, users receive clear warning before the batteries become fully depleted.
Quiet Radiator Control
Traditional motorised smart TRVs can make noticeable noise when adjusting the valve.
neoFlo uses hybrid technology to reduce this problem.
Heatmiser describes its normal operating mode as effectively noise free. Commissioning noise is approximately 30dB(A).
Therefore, neoFlo works particularly well in:
- Bedrooms
- Children’s rooms
- Home offices
- Hotel rooms
- Studies
- Living rooms
- Quiet working areas
M30 x 1.5 Radiator Valve Connection
neoFlo fits radiator valve bodies with a standard M30 x 1.5 connection.
This connection is widely used across modern thermostatic radiator valves.
Furthermore, Heatmiser supplies a Danfoss RA adaptor with the neoFlo. Additional adaptors are available for several other valve types.
Always check your existing valve body before ordering.
Smart Home Compatibility
When paired with neoHub G3, neoFlo can integrate with several popular smart home platforms.
Compatible services include:
- Amazon Alexa
- Google Assistant
- Apple HomeKit
- IFTTT
Therefore, radiator heating can become part of a wider connected home system.
Ideal for Hybrid Heating Systems
Many modern homes combine different heating technologies.
For example, a property may use:
- Underfloor heating downstairs
- Radiators upstairs
- Heat pump heating
- Boiler heating
- Mixed heating zones
neoFlo can extend the existing Heatmiser smart ecosystem into radiator-heated areas.
Therefore, homes already using Heatmiser underfloor heating controls can integrate radiator zones into the same wider smart heating system.
Heatmiser neoFlo and Underfloor Heating
neoFlo itself controls radiators rather than underfloor heating circuits.
However, it can work alongside existing Heatmiser underfloor heating controls.
For example, a property could use:
- Heatmiser NeoStats for underfloor heating
- Heatmiser UH8 or other compatible wiring centres
- neoFlo thermostatic heads for radiators
- neoHub G3 for app control
Consequently, homeowners can manage both radiator and underfloor heating zones within one Heatmiser smart control ecosystem.
