Thermenex
THERMENEX treats large buildings as thermal resources, using heat reclaimed from the building itself for domestic water (DHW) pre-heat and space and ventilation heating. It is a water-filled pipe with a hot end and a cold end, and functions as a hub for the exchange of thermal energy. The system differentiates loads into temperature categories: high (DHW), medium (space load), and low (ventilation air) and provides water temperature based on demand.
