IMI Heatmiser neoFlo Smart Radiator Thermostat

Smart Radiator Thermostat

Old Radiators Can Learn New Tricks

Meet neoFlo — quiet comfort, digital precision and smarter radiator control for modern living.

neoFlo brings smart radiator control into the IMI Heatmiser neo ecosystem. Whether you want to upgrade a single room, add smart control to more radiators, or create a more complete heating setup with app control and call for heat, neoFlo gives you a flexible route to smarter heating.

neoFlo can be used on its own for smart radiator control, or paired with neoHub G3 for app control and smarter scheduling. For a more complete heating solution, neoFlo can also work with neoHub G3 and RF Switch. When the RF Switch is connected to the boiler or other heat source, neoFlo can call for heat, allowing rooms to demand warmth in a similar way to a typical thermostat. See how the full heating solution works.

Built with advanced hybrid control technology, neoFlo combines electronic precision with quiet, stable temperature regulation and long-lasting performance of up to 6 years on just four AA batteries.

Award-Winning Innovation

Recognised for outstanding product design

neoFlo has already gained international recognition for bringing a smarter, more considered approach to radiator control.

Want neoFlo to call for heat?

For setups where neoFlo needs to do more than control the radiator, the full heating solution uses neoFlo + neoHub G3 + RF Switch. In this setup, neoFlo can help enable the heating system to fire when rooms call for heat, while neoHub G3 provides app control, remote access and scheduling.

The RF Switch is the key part of this setup. It receives the signal and must then be wired to the boiler or other heat source output so the system can respond correctly when heat is needed.

Installer note: Where RF Switch is used to call for heat, it must be wired to the boiler or other heat source by a suitably qualified installer.

Choose the level that fits your home

Every home setup is different. Some customers may only need one or more neoFlo units to upgrade individual radiators. Others may also need a neoHub G3 for app control, or an RF Switch if paired neoFlo devices need to call for heat from the boiler or other heat source. The guide below will help you understand the different options.

Please note: neoFlo is only compatible with neoHub G3 and is not compatible with neoHub G1 or G2.

Installer note: Where an RF Switch is used to call for heat, it must be wired to the boiler or other heat source output. This part of the setup should be completed by a suitably qualified installer.

Compatibility and key checks

• neoFlo fits radiator valves with an M30 x 1.5 thread as standard.
• An RA adaptor is supplied in the box.
• neoFlo is compatible with neoHub G3 only.
• For larger hybrid systems, neoFlo can be used alongside existing Heatmiser underfloor heating controls to extend smart control into radiator-heated rooms.
