Rinnai is a world-renowned thermal equipment manufacturer founded in Japan in 1920, with innovative technology and quality control capabilities, it enjoys a good reputation in the wall-hung boiler industry, especially in Japan and South Korea, Rinnai wall-hung boilers occupy a large part of the market share all year round. Every Rinnai product that leaves the factory needs to undergo rigorous testing, and only after passing the test can it be put on the market.
 
The wall-hung boiler in the forest is highly adaptable, and can be used normally even in areas with complex climate and altitude in China. At the same time, the wall-hung boiler has the characteristics of high intelligence, and has carried out a number of technological innovations, which is unique in the wall-hung boiler industry. The constant temperature technology in the forest is first-class, and the gas proportional valve is used to accurately control the gas, and the fluctuation range of water temperature is controlled within 1 degree, and its unique wide automatic constant temperature technology can determine the heat output according to the actual heating demand, so as to achieve high efficiency and energy saving. For users in the southern region of China, the Linnei wall-hung boiler realizes the micro-flame technology to avoid scalding caused by high water temperature in summer. In addition, the triple antifreeze system, automatic water replenishment function, and carbon monoxide prevention device are all examples of Rinnai's cutting-edge technology.
 
Rinnai's products can be mainly divided into several series: Cloud Intelligence, Intelligence, Ruiheng, Warm Environment and Jingdian. Among them, the cloud intelligent series products are the most high-end intelligent condensing furnaces, providing six major modes such as energy saving, comfortable sleep, and going out, and a high-efficiency combustion system has been developed for China's vast and complex regional environment to meet different needs, and the use of dual CPUs can avoid safety problems caused by component failures. The high-end model of the cloud intelligent series is the same as the Ariston ONE series wall-hung boiler, which can be interconnected with a mobile phone, remotely controlled and real-time monitoring of the machine status, suitable for users who have the ultimate pursuit of the functionality of the wall-hung boiler.
 
RBS-25K88 Plus is a representative cloud intelligent condenser, priced at 16390 yuan, which is close to the flagship product of Ariston known for its condensing furnace, but it is not weaker than the latter in terms of performance. RBS-25K88 Plus can automatically push status prompts when the set distance is reached according to the GPS positioning system, and users can immediately turn on the wall-hung boiler and enter the preheating state, and at the same time, each step of the operation can get voice prompts, which is highly convenient and suitable for the elderly at home. Compared to the previous generation, the RBS-25K88 Plus is 42% smaller and 26% lighter, greatly reducing the installation burden. In addition to keeping carbon monoxide and nitrogen oxide emissions at extremely low levels, the RBS-25K88 Plus has a thermal efficiency of 108%, which is excellent even in a condensing furnace and higher than the European aristocracy of Bosch, which costs 24,300 yuan.
