ABSTRACT:
A hot-water type heating apparatus includes a heat exchanger and a flow rate control valve for controlling hot water supplied to the heat exchanger. The heat exchanger includes an inlet side tank placed at a lower side, an outlet side tank placed at an upper side, and a core portion disposed between the inlet side tank and the outlet side tank. An inner space of the inlet side tank is partitioned into four spaces. Hot water from a hot water inlet pipe is divided into four flows, and flows into tubes of the core portion after passing through the four spaces. Because hot water from the hot water inlet pipe is compulsorily divided into four flows to pass through the four spaces, it can prevent hot water from mainly flowing through the core portion at a side proximate to the hot water inlet pipe and a hot water outlet pipe. Thus, in the hot-water type heating apparatus, a temperature difference between air blown from a left side of the heating heat exchanger and air blown from a right side thereof can be decreased without reducing the maximum heating capacity.
