The 4iE is a Smart heating thermostat that works with your smartphone to give you optimal, cost-effective and energy-efficient heating. For use with both electric and water underfloor heating systems, the 4iE does not require programming and uses Warmup’s latest technologies to ensure your home is always at the desired temperature, at the right time, for you.

Making sure your home’s floor heating is gently warmed for when you need it and running at lower temperatures when you don’t, the 4iE and its SmartGeo technology cuts down on energy wastage, thereby reducing your energy costs too. Using the 4iE alongside Warmup’s MyHeating and AutoSwitch apps can save you up to £378 a year on your annual energy bills. 

Warmup’s 4iE Smart WiFi Thermostat for underfloor heating is designed to look great in both modern and traditionally styled homes, with glass effect front faces and bevelled chrome edges. Featuring a clear, full-colour touchscreen that can be customised with different themes and uploadable photo backgrounds.
