Development of a Test Procedure for External Domestic Hot Water Modules
Abstract
The market of DHWM is growing fast, but the absence of a standardized testing procedure makes comparison of the products and quality assessment difficult. Therefore a project is being carried out at SPF aiming at the definition of a test procedure for DHWM. In the first phase a suitable test rig has been set up and six commercially available modules where tested extensively to determine the most important parameters and testing conditions necessary for evaluating the quality of a domestic hot water module. In this paper, an overview over the results of the first testing phase is given, focussing on three main performance indicators: power, comfort and efficiency.
