E3 system
High efficiency heating system with gas absorption heat pumps
The most efficient heating solution in terms of financial savings, conservation of energy resources and reduction of polluting emissions.
Robur gas absorption heat pumps qualify as class A+++ in the heating systems classification model proposed by the European Commission (see the Study “Eco-design of Boilers and Combi-boilers”, www.ecoboiler.org).

The E3 heating system thus immediately guarantees adherence to the demands of the building's energy certification and guarantees the building's promotion to a higher energy class, with a consequent increase in its market value.
The E3 system by Robur guarantees the performance of the entire heating system thanks to the development and integration of the main components of the system:
• the generation system: the E3 absorption heat pump.
• the distribution system: highly efficient Wilo modulating electronic pumps.
• the control system: Siemens Comfort Control.
