First of hot water, hot water in a large mug of water and not guaranteed to be clean, followed by circulating hot water machines common problem: after a period of time will have a scale, on a regular basis (usually 5 to 10 days) thorough cleaning, conditional on sterilization (ozone disinfectant harmless to humans and the like) no conditions should soak in hot water, thus reducing the water heater in the most scale. Also hot water heating cycle so-called boiling water are only just stopped boiling hot air to water machine maintenance, that white is simply not open burning, microbes in the water did not reach the boiling point, when Baidu can not be completely exterminated air to water machine marketing, so if conditions allow, try to burn once a kettle, I hope to help you water electric boilers as an electrical product, its safety is very important. Because most consumers do not have knowledge of electricity, so do not install itself in the purchase of products, the best by a manufacturer of professional installation. Before using the product air heat pump water heater, consumers should read the instructions carefully, follow the water machine, Suzhou water machine, water boilers, water heaters and other product specifications. Air to water machine marketing, the Han Technology (certification), Shangnan hot water provided by the Henan Science and Technology Co., Ltd. Han Yue. Henan Yue Han Technology Co., Ltd. (www.hnlyjd.com/) is Zhengzhou, electronics, electrical products processing leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
