1， 压力要再12-15之间才能work， 我家的只有11， 所以水循环不起来， 这是我的理解啊，反正我也不懂。

The expansion tank has too much or too little water. The tank must be properly charged with air to prevent boiling. Improperly charged expansion tank: In older boiler systems, the steel expansion tank may be found in the attic or suspended between joists in the basement. In newer systems, the diaphragm expansion tank may be attached to the boiler piping near the boiler. The expansion tank must be properly charged with air to prevent water in the system from boiling and exceeding the desired 12 psi of pressure.
