The secondary pressure of the pressure reducing valve (4) is added to hjt ti (1), but there is a pressure L)I due to the expansion of the water as well as the layer temperature of the water, and the pressure is 1.0 kQ / cnl or more. May be added. Therefore, the hot water storage tank (1), which is an airtight container, has a safety valve fO1) that opens when a pressure of 1.0 kg/cm or more is applied, so that the pressure in the hot water storage tank (1) is always safe. 1. It is maintained below okg/cm. When taking out hot water from the lithium storage tank (1) from the hot water outlet α formed in one part of the hot water storage tank (1),
The hot water cannot be discharged due to the internal pressure in 1), but as mentioned earlier, the pressure in the hot water tank (1) is kept below 10 kQ/cm by the safety valve (1).
In the end, hot water is dispensed at a pressure of 1-Okg/(3#/) or less. However, hot water supply at this level of pressure cannot provide comfortable momentum for shower equipment, etc. There are many people who are dissatisfied with the use of hot water. Therefore, in this example, a pressure pump (6) is installed in the hot water outlet pipe o3 that connects to the hot water outlet []04, and a pressurizing pump (6) is installed in the hot water outlet pipe o3 that connects to the hot water outlet pipe The pressurizing pump (6) is designed to be able to send out high-pressure water to the pump (6), which does not exceed the flow bl of the operating characteristics of the depressurizing JP (4) described above (see Fig. 2).
(b) With the characteristics shown in (b), the hot water output characteristics regarding Meteor and pressure as a water heater are generally reduced pressure f(4) and pressurized force f(4). This is the sum of the characteristics of (6) (see t=i in Figure 2). That is, for example, a high pressure of about 1.4 k'J/cnl can be applied for a meteor of 10/min. The pressurizing pump (6) can be operated by closing the meteor switch (5) based on the detection of a meteor on the water supply side, as described above, in response to the opening/closing operation of the hot water tap (not shown). good.

ることができる。As is clear from the above description of the embodiments, the present invention does not exceed the operating characteristics of the pressure reduction device 1, which adjusts the pressure from the water supply side provided on the water supply side of a closed hot water storage facility. Since this is a hot water storage type water heater with a pressure pump installed on the hot water outlet side of the hot water storage tank, it is possible to supply hot water from the hot water storage tank at 17% pressure without increasing the pressure applied to the hot water storage tank. Hot water supply that is satisfactory in quantity and pressure can be achieved.
