<p>A heat balance type water heater includes: a water tank (3), a heater (4), a heat collector (10), a compressor (12), and an expansion valve (15). The heater (4) is provided in the water tank (3) with a water outlet valve (1) on the upper part and a water inlet valve (6) on the lower part. One end of the heat collector (10) is communicated with a liquid outlet of the heater (4) in the water tank (3) through pie expansion valve (15), the other end of the heat collector (10) is communicated with a liquid inlet of the heater (4) of the water tank (3) through the compressor (12). The heat collector (10), the compressor (12), the heater (4) and the expansion valve (15) form a circulation circuit in which refrigerant flows. The water heater also includes a machine case (14) combined into a unity body with the water tank (3). The heat collector (10), the compressor (12), the expansion valve (15) are provided in the machine case (14), a fan (8) is also provided in the machine case (14), the outer wall of the machine case (14) is disposed separately with an air outlet (7) and an air inlet (13) at a distance. The water heater can heat the water in the water heater using the indoor air so as to balance the heat in the indoor air released from the bathed hot water.</p> |
