During the June 29–July 5 product launch window, Haiyan KaiChang Energy-Saving Electronics introduced two smart solar hot water solutions designed for overseas solar water heater dealers, installers and distributors. The launch reflects a clear market trend: solar hot water systems are moving toward remote management, intelligent circulation and stronger freeze protection for different climates.

The first product is a pressurized solar water heater controller. It features temperature display and electric heating, and supports mobile remote control. It is suitable for integrated flat-plate solar water heater systems. For distributors, this controller offers a practical upgrade path for conventional pressurized solar systems that require reliable temperature monitoring and backup electric heating.

The second product is a WiFi zero cold water control system. It supports automatic water filling, automatic heating, automatic anti-freeze circulation, automatic outlet pressure boosting and automatic hot water circulation. The system is aimed at improving hot water comfort, reducing waiting time for hot water and helping reduce freeze risk in cold conditions.

KaiChang is based in Haiyan County, Zhejiang Province, China. The company’s background dates back to 2005, when its predecessor focused on solar water heater accessories. The KaiChang brand was established in 2013 and later focused on pipe draining and anti-freeze projects. The company has accumulated utility model patents, including a customized whole-house hot water system and an automatic switching device for solar and gas water heaters. Its KC-50 solar water heater controller has also obtained CE compliance certificates.

With the brand message “Don’t fear frozen pipes, choose KaiChang,” the company continues to focus on professional, practical and reliable solar hot water control solutions. This latest product launch gives overseas buyers more options for smart solar controllers, WiFi hot water circulation and anti-freeze system upgrades.
