Natural gas heater

A natural gas heater relates to a compressed natural gas heating device; the heater includes a box body, a water sink, an inlet and outlet mouths, a pipeline, a water inlet mouth, and a heater; the box body is provided with the water sink; the upper part of the water sink is provided with the water inlet mouth; the two ports of the pipeline are respectively connected with the inlet and outlet mouths; the pipeline is arranged in the water sink; the water sink is still provided with the heater. The heater of the utility model is provided with two joints respectively connected with the gas tank or the pressure reducing valve; the high-pressure natural gas in the gas tank flows through the heater and is preheated to be 50 to 60 centigrade in the heater; when the gas flows through the pressure reducing valve, the pressure reducing valve will not be frozen; because the heating is done in the pipeline, the pressure is further improved. The utility model uses the high pressure resistant pipeline, increasing the security performance; in addition, the utility model is still provided with the temperature sensor and the regulator, which can adjust the heating temperature according to the environmental condition.
