Stainless steel is not rust free, it simply cannot rust. The water of the stainless steel clad solar water heater that has been used for a long time contains a large amount of rust-soluble heavy metal salts, and this is the case. It is also easy to contain a large amount of rust-soluble heavy metal salts in water. If there is a white deposit on the gallbladder, it should be replaced or cleaned regularly with acetic acid.
The two most common types of water heater linings on the market are ordinary stainless steel and imported food grade stainless steel (SUS304/2B). Solar water using the latter can meet consumption requirements, while). ordinary stainless steel This is not possible.
The solar covering is also made of plastic polypropylene. Polypropylene is non-toxic, odorless, has lowdensity and its strength, rigidity, hardness and heat resistance are better than low voltage polyethylene. It can be used at around 100°C. It has good electrical properties and high frequency insulation. and is not affected by humidity, but by low temperatures. It becomes brittle, not resistant to wear and easy to age. It is suitable for manufacturing general mechanical parts, corrosion-resistant parts and insulating parts. Common acidic and alkaline organic solvents have almost no effect on it and can be used in dishes.
*In short, food grade stainless steel (SUS304/2B) solar liner is the best.
As for the water heater with electric heating function, Huangming, Sanle and other water heaters are not the only ones with this setting, mainly to increase the supply temperature in water duringthe severe cold season in the north

There are two types of probe functions on solar panels, one is one temperature probe and the other is a water level probe. There are two types of materials: plastic and stainless steel.
If it is a domestic solar water heater, I personally recommend plastic. Since stainless steel dissipates heat quickly, water mist is easily formed on the surface of the probe in winter, affecting the accuracy of water level detection. If placed downwards, the impact will be limited.
If it is a technical probe, the tip part of the probe is usually made of stainless steel. Since chloride ions in water corrode stainless steel, the current stainless steel used is 304 stainless steel with relative corrosion resistancely good. .
1. Firstly, the first water pipe of the solar water heater should be connected to the indoor mixing valve. The usual mixer has the function of filling water and regulating hot and cold water. The second pipe is connected directly to the solar overflow port and placed next to the interior floor drain. The function of this pipe is to allow solar water to flow out of this pipe when it is full.
2. Secondly, wrap the water inlet and outlet with raw tape, then install the pipe fittings, connect the special pipe for solar water heater installation, attach the electric heating tape to the outer wall of the pipe , tie it tightly with a sticky tie and install it on the water tank. Install the sensor into the water level gauge hole.
3. Finally, loosen the locking device, insert the metal sensor, insert it into the bottom of the water tank and locklean it to avoid movement and falling. Then connect the water pipe to the water. Tank installed for the solar water heater, then connect the indoor water pipe so that the water storage tank is installed.
