Heat recovery FAQ - Thermal Energy International

15% to 20% of the energy used in a boiler plant is lost up the boiler stack. Thermal Energy's FLU-ACE condensing heat recovery technology effectively recovers this waste energy and uses it to preheat a heat sink – this could be water for your space heating, domestic hot water, boiler feed water, or outside air heating. This can result in
