Title: HOt Water SavEr (HOWSE) Project. Final report

Abstract

The dishwasher effluent is pumped into the flue of the exchange tank by the normal dishwasher pump (or auxiliary pump). The effluent is stored in this tank until next operation of the dishwasher. Thus, thermal equilibrium can be reached between the tank and the effluent, promoting high efficiency. The output from the exchange tank feeds the household normal hot water tank, reducing its requirement for fuel as the input water temperature is higher. Counterflow exchangers may be used for other hot water users where the flow and drain is continuous. In this case the discharged hot (or warm) water flows counter to the flow of cold water into the hot water heater. The two flows are closely coupled thermally but not in direct contract so they cannot mix. Counter flow exchangers and storage type exchangers may be used in the same installation.
