For Underfloor heating systems
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. Underfloor Heating systems are much more efficient in heating a home than traditional radiators by running at lower temperatures to gently reach optimal warmth. Combining underfloor heating with the 4iE allows automatic, intuitive control of heating for a truly Smart home.
Maximises your home’s energy-efficiency
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.
Smarter UFH Control
MyHeating App
The SmartGeo technology within 4iE’s partnered MyHeating app controls your heating automatically by knowing how far from home you are and warming your home in time for your arrival. This prevents energy wastage and can save you up to 25% on your energy bills.
