1. The current solar water heater basically costs more than 3,000 yuan. For example, a solar water heater for 4 or 5 people should cost more than 4,000 yuan. Capacity above 200L is almost the same.
2. An ordinary forced discharge gas water heater should cost between 1000 yuan and 1500 yuan (major brands like Shenzhou, Sakura and Macro). For more than 1,500 yuan, you can consider a safer, balanced gas water heater. 4. For a family of 5 people, you can choose 8L-10L.
3. In terms of reliability and economy, I recommend gas water heaters. After all, these are relatively mature products, and the subsequent maintenance and repair costs are relatively low. Solar water heaters are more difficult to maintain and require climbing onto the roof. Water leakage problems are also common. In terms of saving, the monthly cost of a gas water heater should be around 60 yuan (referringt only at the cost of gas). Calculated like this, this represents 700 yuan per year. Basically, you can catch up on the cost of solar water heaters in 5 years. If it is convenient to use, it is more convenient than gas and boiling water can be heated.
Solar water heaters generally use sunlight. No electricity is needed in good weather. Electricity is used for heating in rainy weather. Therefore, the purchase of solar water heaters should be based on the number of family members. Generally, a pipe of 58 tubes can produce 10 kg of hot water. This calculation is enough, you need to choose the brand yourself and simply accept the service, quality and price. The quality of ordinary solar water heaters is basically the same.
