Number of heat exchangers

The number of heat exchangers provided in the design of the storage tank.

The simplest version of storage tanks are tanks without heat exchangers. They are designed for traditional use in the heating system — to remove excess heat, equalize the temperature characteristics and provide the system with heat in the event of a malfunction in the heater.

Heat exchangers installed in the storage tank can perform two main functions: removing heat from the tank or providing additional heating. One of the most popular options is to work as a water heater for a hot water supply system (in this case, one heat exchanger is enough). As an opposite example (additional heating), a heat exchanger connected to a solar collector can be given. There are storage tanks that have several heat exchangers ( 2 and 3 heat exchangers) and allow several additional applications at once. Anyway, the specific specialization of heat exchangers for each model should be specified separately.
