It is more preferable to provide a (second) thermometer for measuring the temperature of the oil tank, monitor both the temperature of the oil and the temperature of the oil tank, and turn the heater on and off. Thereby, it is possible to prevent the temperature of the oil tank that may be touched by human hands from being excessively heated, and to improve the safety.
  • the entire outer side of the oil tank in the first embodiment, the second embodiment and the fourth embodiment, and the entire outer side of the oil tank and the heater in the third embodiment be covered with a heat insulating material. .
  • the heat radiation amount can be reduced to improve the heat retention, the power consumption of the heater can be reduced, and the running cost can be reduced.
  • the heaters 42 and 82 are configured by four heaters (total 2000 W) having a capacity of 500 W.
  • the temperature of the oil tanks 30, 70 is 30 ° C. or less, all four are used to heat the oil tanks 30, 70, and the temperature of the oil tanks 30, 70 is higher than 30 ° C. and higher than 50 ° C.
  • the oil tank 30, 70 is heated using three of the four when the oil temperature is too low, and when the temperature of the oil tank 30, 70 is 50 ° C. or more, the oil is used using two of the four.
  • the tanks 30, 70 can be heated. That is, under the condition that the temperature of the oil tanks 30, 70 has ample time for heating the oil, the amount of heating from the heaters 42, 82 to the oil tanks 30, 70 can be reduced, and release to the ambient atmosphere. The amount of heat can be reduced.
