Black has the effect of absorbing heat. The reason why rural hot water bottles are black is that black has a heat-absorbing effect, which can improve the absorption of sunlight and accelerate the heating of water. Rural hot water bottles are solar hot water bottles, made of a new type of special double-layer heat-resistant polymer heat-absorbing material, which is windproof, absorbs heat very quickly and dissipates heat slowly.
The solar hot water bottle smells bad, what should I do? (Do not copy the answer)
1. The biggest advantage of solar hot water bottles is that they save installation time and effort and are relatively cheap in price.
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 bad weather.cloudy, rainy or cold. 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.
Hello!
There are two reasons for this. Firstly, the hot water bottle itself is a rubber product, so it is inevitable that there will be a rubber smell when you use it for the first time. In this case, it will improve after using it for a while. If you feel that you can't stand it for a while, you can simply dip the hot water bottle in boiling water for several times to dissipate the smell. Anotherre situation is that the hot water bottle uses poor quality materials. In this case, it will take a long time to eliminate the smell.
This is just my personal opinion, don't comment if you don't like it, thanks.
