2: Accessories are more durable. With the increase of various costs, many imported wall-hung boilers prefer to use gf30pa66 nylon glass fiber instead of brass. However, there are no effective solutions to a series of problems such as water swelling (water leakage), thermal deformation (component deformation), material stress (long-term high-temperature stress cracking) and inconsistent metal expansion rate (interface water leakage), which leads to increased customer maintenance costs.
Saidu insists on using a large number of copper parts to ensure the durability and stability of the machine. Therefore, the weight of Saidu wall-hung boiler reaches 40kg, and the thermal efficiency of conventional boiler reaches 93%.
3. The manufacturer promises the quality assurance, and the manufacturer's quality assurance and the store's exclusive sales are two concepts. The exclusive sale by the manufacturer of Saidu is a quality assurance commitment supported by the manufacturer. The exclusive sales of other imported brands are backed by stores (large and small dealers cancel stores, and manufacturers will not agree to the warranty period). So consumers need to distinguish.
4. Patented hydraulic components. Most of the imported wall-hung boilers in the market used electric three-way motors to drive the hydraulic components of three-way valves decades ago. Its disadvantage is poor durability. If the water quality is not good, it is easy to cause water leakage at the tee seal and damage the tee motor. What's more, water will penetrate into the 220v three-way motor, causing the shell to be charged.
Saidu adopts all-mechanical patented backwater module, which automatically adjusts the water flow through the plate changer according to the domestic water flow. Compared with other imported brands of on-off three-way motors, the change of bath water temperature is smaller, the service life is longer and safer.
