How does Hydromx® work? October 14, 2021 By Hydromx® uses leading-edge nanothermotechnology and a protected formulation to improve heat transfer and works in concert with the room/radiator thermostats and the boiler/chiller controls to reduce energy consumption. By transferring heat more efficiently the system heats up, or cools down, more quickly. As a result, thermostats turn off sooner and the system changes its on/off cycle to save energy. There is a lot of complex science operating at the nanothermotechnology level, but in summary it really is that simple!
