Service

At Kaisundun, we provide customers with considerate service in addition to quality solar products.

Our service begins when we receive the first email or phone call from the customer. Price lists and technical consultations are available upon request. Our helpful staff will assist customers in choosing products that suit their geographic region and price range.

We can also provide samples, but the sample cost as well as the pack and shipping costs is assumed by the customers. If the customer orders products of a full container within one year from the purchase of the sample, the sample cost can be subtracted from the total cost.

To help customers feel secure in their purchase, we offer one-year warranty on the controller and three-year warranty on the complete set of solar water heater, including the water tank, the frame and the vacuum tubes. Within the warranty period, we offer repair, maintenance, or replacement service for damages not caused by misuse or vandalism.

In addition, as the vacuum tube is the most vulnerable part of solar water heater, we offer 1% of the total vacuum tube amount as breakage allowance free of charge. Also, we can offer customers on-site design, customization, training, and OEM services.
