Energy-harvesting controllers are quickly and easily retrofitted to radiators making them intelligent, with energy-harvesting technology they require no wires and no batteries making them low cost and easy to install as well as maintenance free.

The built in Carbon Meter records and reports room level energy consumption and savings and the optional integration of room booking systems and calendars further automates heating and optimises efficiency.

In-room QR codes allow occupants to tweak temperature according to personal preferences (within pre-set limits) and remotely turn it down for periods of absence. This eliminates the traditional trade off between comfort and energy saving allowing both to be achieved.
