Electric and Solar Water Heater Production Line
A water heater is a device that uses various physical principles to increase the temperature of cold water into hot water within a certain period of time. According to different principles, it can be divided into electric water heaters, gas water heaters, solar water heaters, magnetic water heaters, air water heaters, heating water heaters, etc.
The cold air manufacturing part and the hot water manufacturing part. In fact, these two parts are closely linked, inseparable, and must work at the same time. That is, while making hot water, the kitchen is cooled. Or in other words, while cooling the kitchen, hot water is also being made.
We mainly aim to help countries with high electricity and gas costs to build more economical water heaters. For example, storage electric water heaters and solar water heaters.
Electric water heaters are divided into three types: storage type, instant type (also known as fast type) and quick heating type. We focus on the manufacture of storage type enamel liner electric water heaters.
Storage type electric water heater (enamel liner water tank)
The water storage capacity is divided into 30L, 40L, 50L, 60L, 80L, 90L, 100L, etc.
Advantages:Easy to install, easy to use, not affected by the difference in natural gas floor pressure, the first choice of more and more users.
Solar water heater
Solar water heater is a water heater assembled with vacuum collector tubes. It can produce hot water as long as there is light, and can be widely used for household and industrial hot water. It is characterized by high heat collection efficiency (average daily efficiency ≥ 0.46), safety, cleanliness, energy saving, good thermal insulation performance, can be used all year round, and long service life. The specifications include 12 branches, 15 branches, 18 branches, 21 branches, 24 branches, etc. According to the installation method, it can be divided into roof-type solar water heaters and balcony-type solar water heaters; according to the pressure of the water tank, it can be divided into pressurized solar water heaters and non-pressurized solar water heaters.

Water Heater Body Blanking and Forming Line
The steel coils are cut to the required size by hydraulic blanking machines or mechanical punching machines. The steel coil blanks are manually/automatically loaded into a specific hydraulic deep drawing press to form the upper and lower halves of the water heater. The deep drawn parts are then expanded on the flange machine before welding so that the upper and lower parts match when assembled together.

Electric Water Heater Inner Body Welding Line
Pipes and tubes are welded to the upper and lower half of the bottle body by an automatic welding machine. Flange is welded to the upper half of the bottle body. Then the upper and lower half of the bottle body will be welded together by an automatic circumferential seam welding machine. Three-piece water heaters are welded by special automatic longitudinal seam welding machine and circular seam welding machines. The most popular welding technology at present is MIG/MAG welding, which is economical and fast, thus greatly increasing production capacity. If local special gases are scarce, submerged arc welding technology can also be used.

Electric Water Heater Inner Tank Air Leakage Testing, Enameling and Foam Filling Line
Net weight weighing, inkjet printing, valve thread cleaning, valve tightening, leak testing, vacuuming, laser marking, QR code installation and other processes are all automatically completed on the online finishing and leak testing line.
Single-color logos and labels are printed by screen printers, and multi-color logos are printed by automatic pad printers. Currently, many countries require QR codes to be attached to cylinders for subsequent safety management and traceability. China’s GB standard requires welding on the cylinder guard ring, and some countries allow rivets to be riveted on the guard ring.

Solar Water Heater Production Plant
Solar Water Heater is simplified in production, no need many welding machinery. Its main body is formed by the rolling and edging machine. The holes for pipes are punched after rolling by the mechanical press. There are also the inner tank and outer shell on the solar water heater. The whole production line will be more focused on the crimping, resistant welding, conveying, assembly and packaging.
