Referring to FIGS. 3 and 4, in a construction of a heating system 100 using a fireplace according to a preferred embodiment of the present invention, a combustion room 20 is formed at a side wall body of a dwelling house as a built-in type and a discharge hole 23 is formed at the upper portion of the combustion room and connected with a chimney 24 so that smoke is discharged to the outside. A water tank 110 with an arch shape made of metal is installed within the combustion room and an air tank 120 is connected on the upper surface of the water tank through a connection tube 121.

Water is stored in the water tank 110.

A pipe P2 with a predetermined length is flatly placed with a zigzag type under the bottom surface with a constant area A at the neighborhood of the fireplace, the inlet and outlet of the pipe communicated with a side of the water tank. The water discharged from the water tank 110 through the inlet is circulated along the pipe P2 with a predetermined length and then returned to the water tank 110 through the outlet of the pipe P2, whereby the warmth at the bottom surface of the room is maintained by the circulated warm water.

An air tank 120 is installed at the upper surface of the water tank 110 by the medium of the connection tube 121 in order to discharge air within the water tank 110 to the outside.

A reference numeral 1 denotes a water supply pipe which is communicated at a side of the water tank 110 in order to supply water from an outside water supply resource into the water tank 110.

Valves are combined with ends of the pipes P1 and P2 in the vicinity of the water tank 110. The valves may be constructed by solenoid valves and are controlled by a control member which will be described hereinafter. The valve V1 is a hot water discharge valve, the valve V2 is a cold water returning valve. The valve V3 connected with another water tank (not shown) is a discharge valve for discharging the hot water to the another water tank. The valve V4 is an original water supply valve for supplying the water from an outside water supply resource into the water tank 110.

Although the two pipes P1 are installed at the lower side portion of the water tank 110, only one pipe P1 may be installed at the upper side portion of the water tank 110 or the upper surface of the water tank 110.

A reference numeral 130 denotes a circulation pump which is installed at a side of the pipe P1 in order to make the water in the water tank 110 circulate and controlled by the control member which will be described hereinafter.

Reference numerals 152 denote water height sensing sensors which are installed at the upper portions of the water tank 110. Although two water height sensing sensors 152 are disclosed, the number of the water height sensing sensors is not limited. The two water height sensing sensors are installed with the same height. Sensing signals sensed from the two water height sensing sensors can be used individually. The water height sensing sensor is a kind of a contact sensor and contacted with the water filled in the water tank 110, so that the height of the water is sensed and then the sensed signal is transmitted to the control member which will be described hereinafter.

Reference numerals 141,142 and 143 denote water temperature sensing sensors which are installed at upper and both side portions of the water tank 110 and senses the temperature of water filled in the water tank 110 and then transmit the sensed signal. Although three water temperature sensing sensors 141,142 and 143 are disclosed, the number of the water temperature sensing sensors is not limited. The water temperature sensing sensor is a kind of a contact sensor and contacted with the water filled in the water tank 110, so that the temperature of the water is sensed, the sensed signal is changed according to the temperature change of the water and the sensed signal is transmitted to the control member which will be described hereinafter. Sensing signals sensed from the three water temperature sensing sensors can be used individually. The control member 160 receives the water temperature sensing signals C1, C2 and C3 from the water temperature sensing sensors 141,142 and 143 and the water height sensing signal H1 and H2 from the water height sensing sensors 152 and transmits valve control signals CS1, CS2, CS3 and CS4 and a pump driving control signal CS5 to each device.

The water height and temperature sensing sensors 141, 142, 143 and 152 output sensing signals to the control member 160 whenever the height and the temperature of the water are changed.

The control member 160 controls entirely the system, especially, is connected electrically to the water height sensing sensors 152, the water temperature sensing sensors 141,142 and 143, valves V1,V2,V3 and V4 and the circulation pump 130, receives the sensing signals and transmits controls signals.

A reference numeral 161 denotes an alarm driving member which outputs an alarm signal through a speaker 164 when the height and temperature of water are below the reference height and temperature.

A reference numeral 162 denotes a display driving member which displays the height and temperature of the water through a display member 163.

A reference numeral 165 denotes a function input member in which a user inputs functions such as the setting function of the height and temperature of the water or an on/off function of the system and the like.

A reference numeral 131 denotes a pump driving member which is driven by the control signal CS5 of the control member 160, so that the pump 130 is driven.

A reference numeral 132 denotes a power supply member for supplying power to each part including the pump driving member.

An operation of a heating system using a fireplace according to a preferred embodiment of the present invention will be described in detail with reference to FIG. 5.

Referring to FIG. 5, firstly, when a user generates flames F by means of a heating member such as wood or gas and the like within the combustion room 20 in a fireplace, the three surfaces 111,112 and 113 of the water tank 110 installed within the combustion room are enveloped with flames, so that the water within the water tank 110 is heated.

Thereafter, the control member 160 discriminates whether there is a water temperature sensing signal (a step of ST-2). As a result of the step ST-2, if there is a water temperature sensing signal, the control member 160 discriminates whether the temperature of the water within the water tank 110 sensed by the water temperature sensing sensors 141,142 and 143 exceeds a reference temperature (a step of ST-4) through the comparison of the sensed temperature with the reference temperature. Thereafter, if the temperature of the water exceeds the reference temperature, the control member 160 outputs valve control signals CS1 and CS2 and the pump driving control signal CS5.

As the result of the step ST-2, if there is no a water temperature sensing signal, the control member 160 discriminates whether there is a water height sensing signal (a step of ST-12). As a result of the step ST-12, if there is a water height sensing signal, the control member 160 discriminates whether the height of the water within the water tank 110 sensed by the water height sensing sensors 152 is below a reference height (a step of ST-14) through the comparison of the sensed height with the reference height. Thereafter, if the height of the water is below the reference temperature, the control member 160 outputs the valve control signal CS4 so that the water is supplied from the outside water supply resource into the water tank 110.

As the result of the step ST-12, if there is no a water height sensing signal, the control member 160 discriminates whether there is a water discharge signal (a step of ST-22). As a result of the step ST-22, if there is a water discharge signal, the control member 160 outputs the valve control signal CS3 so that the warm water supplied from the water tank is discharged to another water tank through a pipe P3.

The heat system using a fireplace according to an embodiment of the present invention has several advantages that not only the circumference of the fireplace and but also the temperature of the bottom surface of a house are maintained warmly through the heating system of the fireplace and the hot water can be separately discharged and used.

While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
