In life, people can find that the water used by a human body has a habit with the temperature of the external environment, when the temperature of the environment in summer is high (36 ℃), the temperature requirement of the water used by people is low, and meanwhile, the heat dissipation is less when the water is sprayed out, so that the heating temperature requirement of the water heater is much lower (if most of people like setting the water heater to be 38 ℃); when the environmental temperature is low (0 ℃) in winter, the requirement on the temperature of water is high, and meanwhile, the heat dissipation is high when the water is sprayed out, so that the heating temperature of the water heater is high (if most of the water heaters are set to 50 ℃); accordingly, the trend of the temperature of water and the ambient temperature is shown in fig. 2.

therefore, if T0 is more than 36 ℃, T2 is more than or equal to 35 ℃ and less than or equal to 37 ℃, T3 is-5 ℃, and T4 is 5 ℃; if T0 is more than or equal to 27 ℃ and less than or equal to 36 ℃, T2 is more than or equal to 38 ℃ and less than or equal to 41 ℃, T3 is-4 ℃, and T4 is 4 ℃; if T0 is more than or equal to 12 ℃ and less than or equal to 24 ℃, T2 is more than or equal to 42 ℃ and less than or equal to 46 ℃, T3 is-4 ℃, and T4 is 3 ℃; if T0 is more than or equal to 0 ℃ and less than or equal to 9 ℃, T2 is more than or equal to 47 ℃ and less than or equal to 50 ℃, T3 is-5 ℃, and T4 is 2 ℃; if the temperature is more than or equal to-15 ℃ and less than or equal to T0 and less than or equal to-3 ℃, the temperature is more than or equal to 51 ℃ and less than or equal to T2 and less than or equal to 55 ℃, and the temperature is 43 ℃ when T2+ T3 and 51 ℃ when T2+ T4 are used; if T0 is less than-15 deg.C, T2 is more than or equal to 56 deg.C and less than or equal to 65 deg.C, T2+ T3 is 43 deg.C, and T2+ T4 is 51 deg.C.
When the temperature T0 is more than or equal to-15 ℃ and less than or equal to 36 ℃, the corresponding heating temperature T2 is increased by 1 ℃ when the external environment temperature T0 is reduced by 3 ℃, namely, the temperature delta T2 is equal to-delta T0/3.
