Vacuum insulation panels – A promising solution for high insulated tanks

Thermal energy storage (TES) devices, especially hot water tanks lose energy through the surface. To keep the energy loss low, TES are insulated with materials like expanded polystyrene or mineral wool. However, the insulation of small and middle-sized TES is not as good as it should be. With Vacuum Insulation Panels (VIPs), it is possible to reduce these losses by a factor of 6 to 10, compared to conventional insulation materials. This paper describes the possibility of using VIP for insulating TES. This leads to a reduction of the energy loss.
