Abstract
An open pit hot water store, with a volume of 130 m{sup 3}, serving a small district heating system was studied. The store is steel-lined, to allow high charging temperatures, and has a thermal insulation layer of 20 cm below ground level and 30 cm above. Paraffin oil is used as a vapor/oxygen barrier on the water surface. The principal aims of this study was to evaluate stresses, corrosion, waterproofness, heat losses and temperature stratification. These measurements were performed in a single test charging of the store, prior to regular operation of the system, when heat from solar collectors and night electricity will be used. The test results were very good, except for the heat losses, which were 50 percent higher than expected, possibly due to the dampness of the insulating material. (4 refs., 9 figs.).
