供することを課題とする。However, when the temperature of the hot air heater or the hot water radiator is controlled based on the temperature under the floor, the room and the temperature under the floor do not always coincide with each other. Is narrower than the room (the space under the floor is 50 cm long)
(Smaller than room space) Heat capacity is small and easy to warm up. For this reason, the underfloor space reaches the set temperature even though the room temperature is low, and temperature control based on the underfloor space is performed, which causes a problem that it takes time for the room to reach an appropriate temperature. Therefore, if the underfloor temperature is set to a high value, the above-mentioned problems will be solved, but not only will the room temperature rise excessively when heating is stable, but it will also waste energy, and it will be a fundamental problem in highly insulated and airtight houses. Contrary to the idea of keeping the temperature difference of each space within 2 ° C. to 3 ° C. (if there is a temperature difference, dew condensation occurs at a low temperature), it also affects the life of the building. There is such a problem. An object of the present invention is to provide a heating device free from such a problem.

An underfloor temperature detector for detecting the underfloor temperature, and a microcomputer for registering the temperatures detected by the two temperature detectors, and the microcomputer is provided with a combustion amount in the combustor and a rotation of the convection blower based on the room temperature. The room temperature proportional control pattern is set so that the number increases with each increase in the number of proportional stages, and the combustion amount in the combustor and the rotation speed of the convection blower increase with each increase in the number of proportional stages, based on the underfloor temperature. The underfloor temperature proportional control pattern set as above is registered, and the number of proportional stages of the room temperature proportional control pattern obtained from the difference between the room temperature set temperature and the temperature detected by the room temperature detector is set higher than the room temperature set temperature. The microcomputer compares the proportional number of stages in the underfloor temperature proportional control pattern obtained from the difference between the underfloor set temperature and the temperature detected by the underfloor temperature detector with a microcomputer, and selects the smaller proportional stage number from both proportional stages. , By burning at the combustion amount corresponding to the selected proportional stage number and rotating the convection blower at the rotational speed corresponding to the selected proportional stage number, when the temperature at the start of heating is low, the underfloor space having a small heat capacity is used. Since the temperature rises first and the proportional step number of the underfloor proportional control pattern becomes smaller first, the proportional step number of the underfloor proportional control pattern is selected, and the temperature control based on the underfloor set temperature having a higher set temperature is performed, and the temperature is quickly reduced. Can be raised. Then, the room temperature gradually rises while heating is continued. Since the room temperature set temperature is set lower than the underfloor set temperature, the number of proportional steps in the room temperature proportional control pattern becomes smaller than the number of proportional steps in the underfloor proportional control pattern, and thereafter control based on the room temperature proportional control pattern is performed.

Then, during the continuation of the combustion, it is determined whether or not the hot air temperature detected by the hot air temperature detector 19 is lower than a set value (for example, 70 ° C.). If it is lower than 70 ° C., it is determined whether or not a temperature adjustment stop condition has occurred, that is, whether or not the temperature detected by the room temperature detector 17 is higher by 2 ° C. than a set temperature based on the room temperature. If (the room temperature is higher than the set temperature by 2 ° C.) occurs, the electromagnetic pump 27 is stopped to stop the combustion by the combustor 10. Thereafter, it is determined whether or not a re-ignition condition (the room temperature is lower by 1 ° C. than the set temperature) has occurred. If the re-ignition condition has occurred, re-ignition is performed, and the temperature obtained by performing the above-described steps (steps based on the room temperature) is obtained. Perform the key. If the temperature adjustment stop condition has not been generated, the temperature adjustment based on the room temperature proportional control pattern that has been performed in the above steps is performed.
