Can solar water heaters be used in winter?

Almost every household is using solar water heaters now. It is a very good energy-saving water heater, especially in summer when we take a bath every day. It would be very convenient to have a solar water heater. With solar energy, it will also save electricity. But many people want to know whether solar water heaters can be used in winter. Everyone should know that solar water heaters need to absorb heat. If the temperature is high, they can absorb heat better and output hot water better.

Nowadays, every household uses solar water heaters. Does everyone know the working principle of solar energy? It absorbs the sun's heat during the day and converts it into thermal energy, thus turning cold water into hot water. So can solar water heaters be used in winter? Let’s take a look at the introduction below.

1. What is the working principle of a solar water heater? It mainly includes three processes: heat absorption, circulation, and heat preservation.

2. Heat absorption. First, the solar water heater absorbs solar radiation well through a special coating on the surface of the collector and prevents the long-wave emission of radiant heat. Then, the absorbed solar radiation is converted into thermal energy in the vacuum collector tube, which can heat up the cold water.

3. Circulation: The solar water heater utilizes the characteristics that cold water has a greater density than hot water, cold water sinks, and hot water rises, forming a natural circulation in the vacuum tube with cold water flowing from top to bottom and hot water flowing from bottom to top, so that the water temperature in the entire water tank gradually increases to a certain temperature.

4. Insulation: The hot water is insulated through the outer tank, polyurethane foam layer and stainless steel inner tank of the insulation water tank. This will make it convenient for everyone to use hot water at night.

Can solar water heaters be used in winter?

1. Can solar water heaters be used in winter? As you can see from the working principle of solar water heaters above, the answer to this question is yes. But if you want to make better use of solar water heaters in winter, there are certain skills. The principle is that the lower the temperature, the more often and in smaller amounts water should be released, relying on the water temperature to increase the temperature of the pipes and prevent them from freezing and clogging.

2. If the temperature is not very low, refill the water immediately after using hot water that night. This will reduce heat loss that night and make full use of heat energy.

3. If the temperature is relatively low, go swimming after getting up the next day. And put a small amount of water before going to bed or the next morning to prevent the pipes from freezing.

4. If the sunlight is not strong on that day and it is raining or snowing, you can add half a tank of water or more than half a tank of water according to actual needs.

5. If the water consumption is large, you can consider starting the electric heating in the solar water heater or putting the water in the solar water heater into the electric water heater to heat it slightly.

6. When the temperature is below 0℃, be sure to activate the antifreeze device. After mastering these tips, you can make good use of solar water heaters in winter.

Now everyone should know whether solar water heaters can be used in winter. If we understand the working principle of solar energy, we will know that solar water heaters can also be used in winter. At the same time, when choosing solar energy, you must pay attention to the quality of the product and choose some solar energy with a good reputation.
