The invention relates to a safety system for a heat pump system and to a method for operating the safety system. The problem underlying the invention is that a potentially combustible refrigerant can enter the secondary circuit via the corresponding heat exchanger. The safety system according to the invention comprises a control module which is coupled to one or more sensors which detect the cause of the safety shut-off and which are provided in the secondary circuit. The sensors allow gas to be detected in the secondary circuit directly or using variables which suggest the presence of gas. According to the invention, when gas is present in the secondary circuit, the flow through the secondary circuit is reduced by correspondingly controlling the circulating pump. Thus, gaseous refrigerant is prevented from entering the building.
