Designed exclusively by Warmup, the 3iE™ is the world's first fully interactive, touch technology, energy monitor thermostat. Featuring advanced energy monitoring, the Warmup 3iE™ allows you to view actual graphs of your recorded energy consumption against costs. That means you know exactly what your underfloor heating running costs are. The Warmup 3iE™ is also the first programmable 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. The new 3iE™ underfloor heating thermostat strikes the perfect balance between form and function.
