The pressure tank is another important part of the split pressurized system. As it is an entirely separate tank, it can be placed anywhere in the house. The tank can be made with one or two copper coils inside, or without copper coils inside, depending on your needs. Without copper coils, the tank is used as an open loop system and people use water directly from the reservoir. For tanks containing copper coils inside, the coils are usable as heat exchangers, which is better for the lifespan of the tank. Using the heat exchanger, the tank can be connected with existing gas, floor heating or electrically supplemented systems. For every different usage, there’s a connection solution available.
