About Us

Welcome to IMI Heatmiser

IMI Heatmiser brings together decades of smart control expertise with the global engineering strength of IMI Climate Control. Known and trusted by installers across the UK, Heatmiser now operates as a product brand within IMI – expanding what’s possible in connected, energy-efficient heating and cooling.

For over 50 years, Heatmiser has designed and manufactured innovative room thermostats and control systems from our base in Blackburn, Lancashire. Today, that legacy continues under IMI Heatmiser – delivering intelligent control solutions for underfloor heating, radiators and hot water, designed to improve comfort while reducing energy consumption.

Our neo smart control range remains one of the most flexible solutions on the market, offering wired, wireless and RF options to suit every installation. With intuitive app control, smart home compatibility and continuous software development, IMI Heatmiser provides installers and homeowners with connected control that evolves with modern living.

As part of IMI Climate Control – alongside brands such as IMI Heimeier and IMI Pneumatex – we now offer a more complete residential solution. From hydronic system performance and balancing to smart room control, IMI delivers integrated, energy-efficient solutions that work seamlessly together.

The result is greater technical capability, broader system integration, and long-term confidence for installers, specifiers and homeowners alike.
