摘要：The recovery of heat from greywater is one of the methods for reducing the energy demand on buildings. The process may be accomplished, e.g. using a Drain Water Heat Recovery (DHWR) unit installed at the shower drain. The paper analyzes the rationale for a DWHR unit being installed within a joint drain system of two separate shower installations. To this end, Net Present Values (NPV) and Profitability Indexes (PI) were calculated for the different parameters of a building shower operation. The study showed that the profitability of such investment depends not only on the installation's operation parameters but also on the type of energy carrier.
