Appendix G – Application of a Movable Insulating Plate in DHW Tanks Due to the relatively small total volume of the insulating plate and the balancing weight, the correct tuning of the mass of the balancing weight becomes very important. Figure G1 shows the weight difference per litre for city water at 5 to 20oC and hot water at 60 to 85oC. 35 30 25 20 15 60 65 70 75 80 85 Temperature [°C] 5oC 20oC Variable city water temperature Figure G1 The calculated weight difference per litre for hot water at 60 to 85oC and city water at 5 to 20oC. Figure G1 demonstrates that the tuning of the balancing weight is most critical when operating at relatively low hot water temperatures and relatively high city water temperatures. G2 Thermal Resistance of the Insulating Plate The conductive heat flux through a solid insulator is expressed as: (G3) where ∆T is the temperature difference across the plate, and k and L are the thermal conductivity and the thickness of the plate, respectively. The thermal conductivity of 40oC water and some solid insulators of current interest is presented in Table G1.
