With corrugated plate twice-heating exchanger，the boiler for both heating and hot water can provide domestic hot water more stably. After the water supply is cut off, the change range of water temperature is very small, offering better comfortable condition for bathing. It also adopts Italian G20 composite waterway system and the Denmark Grundfos water pump with three speed regulating function, which runs quietly, wear-resisting. With high thermal efficiency, the boiler reach the national secondary energy efficiency standard.
★ The boilers adopt Italian G20 company patent casing bypass valve, which is safe and reliable.
★ The boilers apply Denmark Grundfos regulating water pump，which runs more quietly with better circulating performance.
★ With microcomputer intelligent control system，the temperature can be adjusted freely.
★ Plate heating mode helps with providing more stable hot water.
★ Adopting die-casting aluminum and variable speed draught，the boilers runs more quietly with high efficiency.
★ Timing function is set internally and segmented heating meets individual needs.
★ Multiple safety protection, intelligent three-level antifreeze function, automatic fault alarm and shutdown function ensures safe and worry-free use of the machine.
