Digital energy-saving hero

Intelligent and efficient energy optimization of residential buildings.

With termios.Pro, the joint venture of LEG, Oventrop and mantro has developed a smart thermostat with hydraulic balancing for the housing industry.

In March 2023, LEG, together with the business developer mantro and the Sauerland family-owned company Oventrop, founded the joint venture termios to develop green solutions around heating and sustainability / ESG for residential properties. 

The first solution is called termios.Pro and regulates the hydraulic balance of the heating system automatically for each individual radiator.

It also saves additional heating costs based on intelligent and demand-driven temperature control. The total energy saving is up to 30 percent. Unlike the manual method, no design has to be calculated in advance and no presettings have to be made on the radiator valve. Once installed on the radiator, the digital thermostats control the hydraulic balancing automatically and reliably after a short learning phase.
