How to calculate the energy consumption of hot water

Calculation formula: power consumption (kwh)=4. 18× water consumption (L) × temperature rise (℃)/energy efficiency ratio /3600 If the heating temperature of 1 ton of water (1000L) is increased by 40℃, the energy consumption of electric heating and heat pump will be calculated respectively:/kloc. 2. When the heat pump runs in winter, it is assumed that the energy efficiency ratio is 2.2, and the calculation result is 2 1. 1 kwh; 3. When the heat pump is running in spring and autumn, assuming the energy efficiency ratio is 3.7, the calculation result is12.6 kWh; ; 4. When the heat pump is running in summer, it is assumed that the energy efficiency ratio is 4.8, and the calculated result is 9.7 kWh; ;

Calculation of power consumption: power of electric water heater (kW)× service time (hours) = kWh (degrees). For example, the power of an electric boiler is 1500W, and it is used for 9 minutes (0. 15 hours) each time. The calculated electricity consumption is1.5kw× 0.15h =0.225 kWh, that is, 0.225 degrees.
