neoFlo gives you precise control over every radiator in your home — without the constant noise, short battery life, or temperature swings common with many smart TRVs.
Designed by IMI Heatmiser, with over 60 years of heating expertise, neoFlo uses advanced hybrid control to maintain a steady room temperature quietly and efficiently. The result is consistent comfort, reduced energy waste, and a system that works in the background — not one you constantly notice.
With up to 6 years of battery life from just four AA batteries, neoFlo is built for long-term, low-maintenance performance.
Pair it with the neoHub G3 to bring radiators and underfloor heating into one fully connected system, or use it to upgrade existing radiators with intelligent, room-by-room control.
Quiet by design - Hybrid control reduces constant motor movement, keeping operation smooth
Consistent Temperatures – Minimises overshooting and fluctuation for more stable room comfort.
Long battery life – Up to 6 years of use with minimal maintenance.
Flexible control – Adjust via the neoApp or integrate with Alexa, Google Assistant, and Apple HomeKit**
Straightforward Installation – Wireless setup designed to be quick and installer friendly
Efficient Zoning - Control each room independently to reduce unnecessary heating
neoFlo is part of the IMI Heatmiser neo ecosystem, designed to work across both radiator and underfloor heating setups:
Whether you're upgrading a single room or planning a full system:
Set schedules, adjust temperatures remotely and avoid heating unused rooms. neoFlo gives you control where it matters.
* Hybrid Control - How it works
neoFlo uses an electric motor for adjustment, then maintains temperature using a traditional TRV. This reduces noice, limits unecessary movement and improves efficiency.
** Voice control available when paired with neoHub Gen 3.
