The smart floor heating thermostat

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

 An app controlled WiFi floor heating thermostat

The 4iE is an app-controlled WiFi heating controller that maximises the energy-efficiency of a floor heating system. Floor heating is much more efficient in heating a home than traditional radiators by running at lower temperatures to gently reach optimal warmth. Combining floor heating with the 4iE allows automatic, intuitive control of heating for a truly Smart home.

 Maximises the home’s energy-efficiency

Making sure the home’s floor heating is gently warmed for when needed and running at lower temperatures when heating is not needed, the 4iE and its SmartGeo technology cuts down on energy wastage, thereby reducing energy costs too. Using the 4iE alongside Warmup’s MyHeating app can save on energy bills.

Never come home to a cold house or overpay on energy bills again.

Always at the right temperature. Efforlessly!

SmartGeo™ technology makes sure the home is automatically warm just when arriving and running efficiently when away. 

SmartGeo works using location services built into smartphones as well as learning your routines and the most efficient settings for your home. Your home is automatically warm as you arrive, running efficiently when you are away.

Just like magic!

Easy to use

The 4iE’s heating controls are user friendly and does not require programming. The set-up can be completed within a few simple steps. Installs just like a standard thermostat. The WiFi setup is eary just like a smartphone.

4iE Heating Control Features

Warmup’s 4iE Smart WiFi Thermostat for floor 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, the 4iE can also be personalised to match the décor with a range of colourful vinyl and textured metal and wood effect overlays.

The exclusive Smartgeo™ works in the background to automatically set the perfect temperature. Unlike other inefficient occupancy sensing systems, the 4iE uses location services already built into smartphones, to automatically detect if you are on your way home, even if it is unexpected, so you never come to a cold home.

MyHeating App

The SmartGeo technology within 4iE’s partnered MyHeating app controls the heating system automatically by knowing the distance from home and warming the home in time for arrival. This prevents energy wastage and can save up to 25% on energy bills.
