A method is proposed for regulating a firing device taking into account the temperature and/or the burner load, in particular with a gas burner, comprising the regulation of the temperature (Tactual) produced by the firing device using a characteristic which shows a value range corresponding to a desired temperature (Tdesired) dependent upon a first parameter (mL, VL) corresponding to the burner load (Q), wherein when representing the characteristic, a second parameter, preferably the air ratio (λ), defined as the ratio of the actually supplied quantity of air to the quantity of air theoretically required for optimal stoichiometric combustion, is constant.
