Development of a Buried Hot Water Storage - Measurement and Simulation
Abstract
In order to achieve high solar fractions in heating systems of single or multi family houses, large collector areas and storage volumes are needed. In most cases this storages are placed in the basement of the building, where low room height and small entrances limit the possible storage volumes. Thus large storage volumes are only possible by on-site fabrications or by assembling of small tanks to a storage cascade. Both ways are complex and expansive solutions and occupy much space in the basement (Wilhelms, 2008). In addition, the thermal losses increase, as surface to volume ratio increases significantly with tubed tank cascades.
