Generally speaking, if it is more than 5-6 years old, it is recommended to sell it directly for scrap! If you get it within that time, you can give it to someone else to use!
Recommend "Dr. Sun" solar energy and Sancang solar energy (no need for water level probes and solenoid valves). Heating and hot water usage rates are fast in rainy weather, as is after-sales service. the rate is also significantly reduced, saving time and energy. This model only takes 20-30 minutes to heat without sunlight, while a single warehouse one takes 2-3 hours.
I don’t know! what do you mean ! Where is he ? Because there are several connections to the place you mentioned. 1. The connection between the water pipe and the joint depends on the type of pipe you are using. the connection is not good enough when hot melting, causingwater leak ; For aluminum-plastic pipes, the screws are not tightened or the sealing ring is damaged. 2. The connection between the joint and the water tank pipe is often caused by. the raw material tape is not wrapped properly. 3. The connection between the water tank pipe and the water tank. There are two commonly used connection methods: soldering type and silicone gasket type. The tank needs to be replaced. If it is out of warranty, you need to find an argon arc welding master to remove the insulation layer and weld it. If you do not have a replacement in stock, you can replace the seal ring on the. top exhaust port (which is universal for solar power). In my opinion, the seal ring is most susceptible to damage
