IMI Heatmiser Thermostats

From single-room retrofits to large-scale commercial projects, IMI Heatmiser offers the UK's most versatile range of heating controls. At Underfloor Store, we supply the complete IMI Heatmiser ecosystem, designed for both electric and water-based underfloor heating.

Smart, Scalable and Hub ready

The core of the range, the neoStat series, is a collection of 230v, 12v, and wireless controls that adapt with the home. When paired with the neoHub G3, your system gains remote access globally and full integration with Apple Homekit, Amazon Alexa, and Google Home. For installers, mesh technology ensures a reliable signal across any property size, while homeowners benefit from the intuitive neoApp interface and Geolocation energy savings.

Solutions for every installation

Water-Based Systems: From the flagship neoStat v3 to the wireless neoAir, manage multi-zone manifolds with ease. Pair with the UH8 wiring centre and TA230 actuators for a professional, organised system.

Electric Underfloor Heating: The neoStat-e and Touch-e models are specifically 16A rated for high load electric mats. Each unit includes a 3m floor probe to protect sensitive floor finishes, such as vinyl and timber.

Specialist Controls: The range includes 0-10V Fan Coil thermostats (HC1) for HVAC systems and Modbus compatible Edge models for building management systems.

Efficiency by Design

Whether you are retrofitting a single room with a neoStat WiFi or commissioning a large-scale commercial project, IMI Heatmiser delivers. Features like Optimum Start and Temperature Averaging ensure maximum comfort with minimum energy waste.
