Description

  The present invention relates to a hot water storage type hot water supply apparatus configured by connecting a heat source unit to a tank unit.

  Conventionally, hot water generated using heating means such as a heat pump is stored in a hot water storage tank, and when the hot water storage tank runs out, hot water is stored using an auxiliary heat source such as a gas water heater. A type hot water supply apparatus is known (see Patent Document 1 below).

  The main body of this hot water storage type hot water supply apparatus is composed of a tank unit and a heat source unit. The tank unit includes a hot water storage tank and a plurality of pipes extending from the hot water storage tank, and the hot water storage tank and the pipes are accommodated in a tank housing. The heat source unit includes a heat source device, which is a so-called gas water heater, and a plurality of pipes that extend below the heat source device. The heat source unit is placed on and connected to the support base, and the heat source is provided inside the support base. A plurality of pipes extending downward from the machine are accommodated. The heat source unit is assembled adjacent to the tank unit to form a main body as an integral composite unit.

  By the way, for example, when installing a hot water storage type hot water supply apparatus on a concrete floor such as a balcony of an apartment, the main body is connected to an anchor bolt driven into the concrete floor. At this time, conventionally, the lower end of the support leg provided in the lower part of the main body is fixed with an anchor bolt (see Patent Document 2 below).
