Because the real to the warranty, manufacturers require a considerable investment, as solar water heaters need to face the winter cold and summer heat test, manufacturers need professional inspection every year to maintain, the price of solar water heaters that contain this part of the service fee. Simply a low price to attract consumers of the manufacturers is very difficult to fulfill this commitment.
Industry to remind consumers: buying home solar water heater be sure to select well-known brands and good after-sales service dealers. Because domestic solar water heaters are durable consumer goods, and usually installed in the roof, once a fault, the user is difficult to themselves, so after-sales service must be protected.
