What determines the loss of a heat storage tank?

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.

What determines the energy content of a storage tank?

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. For very large storage tanks, the A/V ratio is very small and the heat losses relative to the energy content are also small.

What is the main form of heat leakage of the tank wall?

The main form of heat leakage of the tank wall is that the heat on the outer surface of the tank wall conducts heat to the inner tank through the tank wall and cold insulation materials . Assuming good contact between layers of cold insulation material, contact thermal resistance is not considered.

What is the difference between heat conduction and heat leakage?
