Claims

[Claims for Utility Model Registration] 1. For absorbing the expansion of can water in the upper part of a can body, which consists of a plurality of cast iron middle sections connected horizontally in sequence between a cast iron front section and a cast iron rear section. In a cast iron sectional pressureless open type hot water heater in which an open tank is directly installed and the canned water portions of each adjacent cast iron section are communicated through an upper nipple and a lower nipple, the upper nipple penetrates from the section at one end. A canned water suction pipe with an open end is inserted through the hole into the upper canned water section of the section at the other end. A cast iron sectional that is equipped with a heat exchanger connected to a return pipe that exchanges heat with the high-temperature can water sucked from the water suction pipe and returns the lower-temperature can water back into the can body. Pressureless open type hot water heater. 2. The cast iron sectional water pump according to claim 1 of the utility model registration claim, in which a can water circulation pump that sucks high-temperature can water from the can water suction pipe is installed between the can water suction pipe and the heat exchanger. Pressure release type hot water heater. 3. The cast iron sectional pressureless opening according to claim 1 of the utility model registration claim, in which a can water circulation pump that sucks high-temperature can water from the can water suction pipe is installed between the heat exchanger and the return pipe. shaped hot water heater.
