The difference between solar hot water tanks and solar water heaters

1. The biggest advantage of solar hot water bottles is that they save installation time and effort, and the price is relatively cheap.

2. Solar hot water bottles can be used when there is sunshine, but the thermal insulation properties of hot water bottles are very poor and cannot be used in cloudy, rainy or cold weather. Especially in winter, hot water bottles are useless.

3. Solar water heaters have higher heating efficiency, stronger heat preservation capabilities, automatic water storage and large water storage capacity.

4. Solar water heaters have a longer lifespan and can be used for many years after just one installation. Solar water heaters are much more powerful than hot water bottles.

I am a practitioner of solar water heaters. I don't know if the solar hot water bottle you havementioned is the black plastic bag commonly used in Shandong and other areas for rooftop bathing. If so, it's simple: it is a closed black plastic bag to which two pipes are connected, one for the water inlet and the other for the return signal pipe. 'water. When using, first place the plastic bag on the roof with direct sunlight and use the tap water pipe to fill the plastic bag with water through the water pipes upper and lower. When the water is full, water will flow out of the signal pipe. , and the tap water will be turned off. As the black plastic bag absorbs heat easily, it naturally heats the water inside and can therefore be washed in the evening.

This thing is relatively cheap and can usually be bought for a few dozen yuan. However, as it cannot retain heat, it can only be used in summer and, indue to the aging of the rubber, it is used. Generally can only be used for one year.
