Warmup 4iE WiFi Thermostat

Your Smart Underfloor Heating Thermostat

Easy to use and fully compatible with Warmup’s electric and hydronic floor heating systems, the 4iE Smart WiFi Thermostat saves you energy and money.

 An app controlled WiFi underfloor heating thermostat

The 4iE is an app-controlled WiFi heating controller that maximises the energy-efficiency of a floor heating system.

Combining underfloor heating with the 4iE allows automatic, intuitive control of heating for a truly Smart home.

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.
