This invention relates to a heater. A combustion air blower feeds combustion air to a burner device. The burner device burns a gas-air mixture from the combustion air and a fuel and serves for heating air. A circulating air blower discharges heated air from the heater. A control device acts on at least one component of the heater, wherein a night mode parameter set associated with an operation of the heater in a night mode and a default parameter set are stored in a data storage device. After an activation of the night mode, the control device accesses the night mode parameter set and uses the same for acting on the component. The night mode parameter set effects a reduction of background noise generated by the heater.

The present disclosure relates to a control method of a gas furnace comprising a step for measuring an indoor temperature, a step for comparing the indoor temperature with a set temperature for heating, and a step for operating the gas furnace in weak heating with a predetermined heating capacity which is lower than a maximum heating capacity of the gas furnace, when the set temperature for heating is higher than the indoor temperature by a temperature value which is less than a predetermined temperature value, wherein the predetermined heating capacity for weak heating is maintained at a current heating capacity for weak heating, when the gas furnace operates in weak heating, and when an operating duration with the current heating capacity for weak heating is less than a first time value.

An intelligent heating system device is provided with processing, communications, and other information technology components, for remote monitoring and control and various value added features and services, embodiments of which use a renewable energy-powered electrolyzer to produce hydrogen as an on-demand fuel stream for a heating element of the heating system.
