Heat loss in heat storages
What does affect heat losses? The losses of a heat storage depend primarily on the so-called A/V ratio, i.e. the ratio of storage surface (A) to storage volume (V). The storage surface determines how large the losses are (double the surface leads to double the heat loss). The volume determines the energy content of the storage tank.
