PURPOSE: To make it possible to use a low temperature heat medium, such as water as a high temperature heat medium, by connecting a high pressure holder to which non-condensable gas is sealed to a flow passage where high temperature fluid is flowing, and applying pressure to the liquid flowing in the passage.
CONSTITUTION: An accumulation tank 1 is provided with a heat exchanger section 3 which transmits the heat accumulated in an accusation member 2 inside the accumulation tank to a heat medium inside, and a closed-shaped circulation passage 5 for heat medium including a heat exchanger section 4 which exchanges heat between a fluid to be used by heating and a heat medium. At the top of the ring-shaped passage 5 is connected a high pressure holder 6 to which none-condenced gas, such as nitrogen gas is sealed. A safety valve 7 is connected to this high pressure holder 6. It is desirable that all parts excluding the heat exchanger 4 between the accumulator 1 in the ring-shaped passage and the fluid to be used should be coated with insulation 8. On the way of the ring-shaped passage 5 installed is a pump which drives the heat medium if required. If a pressure which exceeds the pressure required to maintain the liquid phase is applied to the pressure prevailing in the ring-shaped passage, the vaporization in that part can be inhibited. At the same time, the damage to the system can be prevented as well.
