Instant electric water heater or solar energy, which is better?

1. In terms of price, solar water heaters are more expensive.

2. If it suits me, an electric water heater is more practical. Whenever I want to use direct heating, solar won't heat if there is no sun and the pipes will freeze easily. and prevents water from draining in winter. But you can install electric auxiliary heating, which may slow down the heating of the water.

3. If you want to use it all the time in the future and use a large amount of hot water, it is recommended to buy a solar water heater from a general brand with good after-sales service. If the local temperature is low, it is sufficient to insulate the pipes. If the measures are taken correctly, there will be no problems.

4. Solar energy is an inexhaustible resource. Nowadays, it is a low-carbon, environmentally friendly and green economy. It is best to buy a chasolar water heater. . .

Your problem should be that the solar water heater takes a long time to heat up. The specific reasons are:

1 Because of power. of the solar water heater is very weak. The electric heating of solar water heaters is generally configured with a power of 1500 W, which is not more powerful than an electric water heater; the main reason is that solar electric heating is only used to heat the water tank when the temperature is insufficient, mainly to ensure energy saving, unlike electric water heaters, which need to be configured to heat directly cold water above 60°C.

2. Since solar water heating relies primarily on the sun, the water temperature can reach 80 degrees or more with enough sunlight. In winter or rainy days. Solar heating is fundamentalntally useless. To raise the water temperature, use electric heating. Because electric heating is an auxiliary function of solar energy. Generally, the power varies depending on the size of the water storage device, usually 2 kW or more. If the temperature of 200 kg of water in the water tank is around 1 degree, you want to heat it to 40 degrees. Of course, this takes a long time. Therefore, the temperature of the electric heater should be adjusted at ordinary times, for example, to 50 degrees. The auxiliary heating must be powered 24 hours a day. This way you won't have to wait for the temperature to reach zero to use water. Since you set the temperature to 50 degrees, the electric heater will automatically stop working when this temperature is reached. Since the water storage tank has an insulating layer, you don't have to worry about too much consumption.er a lot of electricity.

3. If you don't like slow heating, you can suggest connecting an instantaneous electric water heater (i.e. rapid heating) in series indoors to heat quickly. However, the power of rapid heating is generally very large, above. 7KW, so take into account the electrical load reserved for the household.
