Some of Solar water heater
Solar water heater: energy saving is the cheapest today, at most it is heated by electricity in winter. When I bought it, I did not let it receive electricity. Basically, a family of three with 20 tubes is enough. In summer, wash ten a day. You do n’t have to worry about the lack of hot water, but you can also get it to the kitchen and the sink. You can let it go. The hot water is usually used for boiling water. In the winter, the hot water in the washing machine is solar water. , I have considered that a solar hot water outlet is connected above the washing machine, think about how much you should save. It is the most energy-efficient of the three.
First wash the dishes clean with hot water, save; wash your face with hot water, save; boil water, the water temperature has reached dozens of degrees, less than half of the time, and save (this is just my personal opinion, Do n’t learn what I do, because the internal structure is unclear and I do n’t know if it meets the drinking requirements, I hereby declare). It's a lot of people's reluctance to do hot water washing in the washing machine. With solar energy, people who save money will become generous.
