The aim of the project is to investigate the change in temperature stratification due to the operation of a circulation pipe. Further, putting forward rules for design of pipe inlet in order not to disturb the temperature stratification in the hot water tank. A validated computer model based on testdata is made. The model is used to determinate the thermal performance of the system as a function of inlet shape and position.
