Claims

[Claims for Utility Model Registration] (1) In a water heater in which a water pipe communicating with a water supply pipe is wound around a pot and this water pipe is connected to a heat exchanger at the upper part of the pot, a flowing water circuit parallel to the water pipe. 1. A gas instantaneous water heater characterized in that the diameter of the water pipe is made small while securing a predetermined amount of water passage. (2) The gas according to claim 1 of the utility model registration claim, characterized in that the water passage circuit is also wound spirally around the pot as a water pipe, thereby ensuring a predetermined amount of water flow and making both water pipes small in diameter. Instant water heater. (3) The scope of the utility model registration claim, characterized in that the water supply circuit is used as a bypass circuit to directly communicate the water supply pipe with the inlet of the heat exchanger, thereby ensuring the amount of water flowing and reducing the diameter of the water pipe. The gas instantaneous water heater according to item 1.
