This system requires an “open” or atmospheric
water system, which means water can be
supplied at an average flow rate to the energy
recovery system. Once the water has been
preheated, it can be pumped or gravity fed
to a hot water tank, thus eliminating the
problems of older “closed” or pressurized stack
economizer designs.
