Available exclusively from Warmup, the 3iE™ is the world’s first fully interactive, touch technology, energy monitor thermostat. It now comes with a thinner and more resilient floor sensor for easy installation.

The Warmup 3iE™ is also the first programmable underfloor heating thermostat to come with Active Energy Management™, which can save you up to 10% on your energy bills by actively prompting you to test lower energy consumption levels.
