OS-32 A study on the planning and evaluation method for the new age of energy saving domestic hot water system : (Part 5) Measurement of bathtub temperature drop in existing houses

Abstract

This report shows the influence of the thermal performance of the bathroom and the bathtub on the temperature change and the bathing patterns based on measured data and a questionnaire results. As a result, it is observed that there is a clear relationship between the thermal performance of bathroom and the terms such as building type. It is also suggested that as for the well- insulated bathtub, temperature drop is suppressed while using the bathtub cover and that the effect was not observed clearly in case without the cover.
