Staying warm during the colder seasons is a significant concern, especially when taking a bath. Besides using heating appliances like bathroom heaters and warm air blowers, maintaining a constant water temperature is also crucial. When it comes to home renovations, the choice between a gas water heater and an electric water heater is a common dilemma. What are the differences between these two? Today, let’s focus on electric water heaters.
Four key data points for analyzing electric water heaters:
1.1 yuan – Cost per shower: The cost of taking a shower primarily depends on one’s bathing habits. If we consider a person taking a 30-minute shower, with an electric water heater operating at 2000 watts and using approximately 40 liters of hot water per shower, the expense for a single shower using an electric water heater is about 1.1 yuan.
100 yuan – Average annual family expenditure on showers: Assuming a person takes 150 showers per year, with each shower lasting an average of 30 minutes and using about 20 liters of water, and with the electric water heater’s power rated at 2000 watts, they would consume approximately 150 kilowatt-hours of electricity and 3 tons of water per year. Consequently, the average annual cost for showering is about 100 yuan.
75 degrees Celsius – Maximum water temperature: During spring and autumn, the ideal water temperature for bathing is around 40 degrees Celsius. Electric water heaters can generally heat water up to about 75 degrees Celsius, but this temperature can also be affected by environmental factors and water pressure, sometimes preventing it from reaching the highest temperature.
0.6 square meters – Average space occupied: On average, an electric water heater occupies about 0.6 square meters of space. Although it may not seem much larger than a gas water heater in terms of area, electric water heaters, due to their storage component, require a greater height, thus needing a larger volume of space to accommodate them compared to gas water heaters.
