Abstract
A hot water-centered hot water and heating combination boiler includes: a cold water inflow tube through which cold water flows in; a main heat exchanger which heats the cold water flowing in through the cold water inflow tube by using the combustion heat of a burner; a hot water discharge tube which discharges the hot water heated in the main heat exchanger; an auxiliary heat exchanger which supplies heating water during a heating mode, in which heating consumption place, and causes heat exchange to occur between the heated water in the main heat exchanger and the lowered temperature returning water, in which the heating consumption place; and a control part which controls the combustion of the burner during a hot water mode and heating mode.
Claims7
A hot water-centered hot water and heating combination boiler comprising:
- a cold water inflow tube to which cold water is introduced;
- a main heat exchanger includes at least one heat exchanger for heating the cold water introduced through the cold water inflow tube by using combustion heat of a burner and a heating latent heat heat-exchanger for heating water circulating through a fluid circuit comprising a heating consumption place by using combustion heat of the burner when a heating mode is operated, the fluid circuit fluidly isolated from a circuit comprising the at least one heat exchanger;
- a hot water discharge tube for discharging hot water heated in the at least one heat exchanger;
- an auxiliary heat exchanger for heat-exchanging heat from water heated in the at least one heat exchanger with returning water that is reduced in temperature in the heating consumption place to supply heating water to the heating consumption place in the heating mode;
- and
- a control part for controlling combustion of the burner in a heating hot water mode and the heating mode.
