Annde will tell you about the advantages and disadvantages of water heater

Storage water heater

Advantages:

1. The incoming line of power supply is relatively small, so there is no big requirement.

Disadvantages:

1. Waste: the whole barrel of water should be heated when washing face and feet.

2. Unhealthy: the water in the cylinder is heated repeatedly, which affects the water quality; There will be dirt accumulation, polluting water quality, breeding bacteria, affecting health.

3. No energy saving: when the storage water heater heats the water to your set temperature, the temperature controller in the water heater will cut off the power supply. When the water temperature slowly drops to a certain temperature, the temperature controller will immediately turn on the power for heating, and then turn off the power supply after the set temperature, so it goes round and round; It's a waste of electricity.

Inconvenient: the storage of water has a certain limit. When taking a bath, you can't wash as long as you want.

solar heater

Advantages:

1 energy saving: almost no electricity is needed

Disadvantages:

1.Unhealthy: most of the water in the solar water heater is reheated, mainly because the water heater has been used for a long time, some of which are old water (i.e. unused water), and there will be dirt accumulation, among which there are many harmful substances, and water pollution breeds bacteria, which affects health; In addition, in summer, the water temperature in the water heater will reach 100 degrees, and the heating time is also very long.

In this process, a lot of nitrite will be generated, and nitrite is the main killer of human health. The experts of secondary distilled water in the family do not recommend to use it, let alone the solar water heater, which is a container out of bad environment.

3.Health: cold water in hot water out, no secondary pollution.

4 constant temperature: the computer chip controls the water temperature and the outlet water temperature.

5. Easy installation.

Disadvantages:
