Solar energy has the advantages of solar energy, and electric water heaters have the advantages of electricity.
Solar energy
1. After spending money to buy a solar water heater, there are virtually no running costs later.
2. Restricted use
The disadvantages of solar energy are also obvious When the weather is bad, especially when there is heavy snowfall in winter in the north, the water inside can accumulate. be drained only to prevent freezing. If the water pipe breaks, it will naturally be impossible to take a bath in continuously cloudy weather. The water heater then lost most of its meaning.
3. Relatively safe
There are no problems such as leakage, and it is relatively safe to use
Electric water heater
1. The cost of usage is relatively high.
Because the transformation of watercold to hot water depends entirely on electricity, part of the electricity bill must be invested every year.
2. There are no restrictions on use. The electric water heater can guarantee hot water 24 hours a day. It can not only take a bath at night, but also wash your face, hands and vegetables during. the day. This will not be affected by weather and other factors.
In summary, I think electric water heaters are more practical in the north, while solar energy can be considered in the south. After all, solar energy is more abundant in the South.
In addition, there are now water heaters that combine electric and solar energy. They rely on solar power when the sun is shining and electricity when there is no sun. This not only satisfies the hot water supply in case of snow. days, but also The subject can consider theThe cost savings of Sunny Day, and the price is not expensive.
Let me teach you another way to save money. You can go to a newly built community. Now, developers of newly built communities will force the installation of water heaters. Most people don't like it and will take them apart. , sell it and replace it with a new one. In this way, most of them are intended for solar and electric use. You can buy one. They are brand new and you can use them with confidence.
