Preheat feed-water by using：
•waste heat
•economisers using combustion air
•deaerated feed-water to heat condensate
•condensing the steam used for stripping and heating the feed water to the deaerator via a heat exchanger
Reduce heating/cooling needs by：
●building insulation
●efficient glazing
●air infiltration reduction
●automatic closure of doors
●destratification
●lowering of temperature set point during non-production period (programmable regulation)
●reduction of the set point for heating and raising it for cooling
Improve the efficiency of heating systems through：
●recovery or use of wasted heat
●heat pumps
●radiative and local heating systems coupled with reduced temperature set points in the non occupied areas of the buildings
