The temperature controller is generally around 200, and there is no need for expensive ones. Electric heating, 50-100 yuan, other reference markets**.

Water heaters are not very unfamiliar to everyone in life, because they are used more frequently when taking a bath, and everyone needs to know more about its quality when buyingAccessories for solar water heaters1. The solar meter is the heart of the whole solar water heater, and it is the headquarters of the operation of the solar water heater, and the functions of solar water replenishment, heat preservation, and electric heating are controlled by it. If the quality of the solar meter is not reliable, there are endless problems. The original solar meter controller is a doorbell type, and the display is replaced with a bright spot.

After 2002, the large-screen color LED digital display was launched, and the operation status was displayed in Chinese, which filled the gap in the domestic solar meter industry in this field and triggered a major change in the solar meter industry.

2. The upper and lower water pipes and water pipes are the channels connecting the solar water heater and the user, if there is a problem, it will flood the gold mountain or fill the camp with water, and the consequences are unimaginable. The water pipes used for solar energy are glued pipes.

3. Booster pump. As an important part of the solar water heater (system), solar accessories play an important role in the realization of the function and performance improvement of the solar water heater (system).

4. At present, in the field of solar water heating, vacuum tube solar water heaters are being widely used, including traditional rooftop integrated solar water heaters, as well as in-line manifold Taiyuan Haoyang energy collectors.

How to choose accessories for solar water heaters.

1. The key component of the household solar water heater is the all-glass vacuum solar crack side energy collector tube (referred to as the vacuum tube), and the quality of the vacuum tube directly affects the performance of the entire household solar water heater. When purchasing, you should carefully observe the coating on the glass tube in the vacuum tube, this coating is called solar selective absorption coating, due to the different production processes of various manufacturers, the coating color will be different, but it is generally black, dark blue or dark gray, the coating color is uniform, the film layer has no scratches, no peeling or falling off, and there are no stones or nodules on the glass, and the support parts supporting the inner glass tube are placed correctly and not loose.

2. The number of permanent residents in the home should also be taken into account when purchasing, so as to determine the size of the water capacity of the purchased household solar water heater. Generally, the standard of 40 liters of water per person is appropriate.

3. The nominal water capacity of many products is calculated by calculating the capacity of each vacuum tube and the capacity of the tank tank, but in fact, the water below the water heater outlet and the vacuum pipe cannot be released for use, and the water that the user can really use is only the amount of water between the water inlet and the overflow port, so the seller should be asked clearly when purchasing, and the water capacity they nominal refers to the total water capacity or the actual water capacity that can be used, and how much is the difference between the two.

Solar water heater can often be seen in life, in order to ensure the quality of the product when choosing, we need to know more about its accessories, the above is for you to introduce what are the accessories of solar water heaters and the purchase method of solar water heater accessories is over here.

1. a collector.

Collector elements in the system. Its function is equivalent to that of an electric heating pipe in an electric water heater. Unlike electric water heaters and gas water heaters, solar collectors use the radiant heat of the sun, so the heating time can only be when the solar irradiation reaches a certain value.

2. Insulated water tank.

Containers for storing hot water. The hot water collected through the collector tube must be stored in an insulated tank to prevent heat loss. The capacity of a solar water heater refers to the capacity of water that can be used in the water heater, excluding the capacity that cannot be used in a vacuum tube.

For pressure-bearing solar water heaters, their capacity refers to the capacity of the medium where heat exchange can occur.

The solar water heater insulation tank is composed of three parts: the inner tank, the insulation layer, and the water tank shell.

3. a bracket. Shelves that support the collector and the insulated water tank. It is required to have a firm structure, high stability, wind and snow resistance, aging resistance, and no rust. The material is generally stainless steel, aluminum alloy or steel spraying.

4. Connect the pipeline.

The solar water heater is to first feed the cold water into the hot water storage tank, and then deliver the heat to the insulated water tank through the collector. The hot water storage tank is connected to the indoor cold and hot water pipelines, so that the whole system forms a closed loop.

5. a control component.

Generally, household solar water heaters need automatic or semi-automatic operation, the control system is indispensable, the commonly used controller is automatic water, water full and water cut-off and display water temperature and water level, solar water heaters with electric auxiliary heating also have leakage protection, anti-dry boiling and other functions.
