This series are boilers for heating and hot water, with double-pipe heat exchanger and adopt the Denmark Grundfos G20 water pump, which runs quietly and the circulation performance is excellent. This product has obtained the national patent with the patent certificate number of ZL201220319328.6 and ZL201530085084.9. With high thermal efficiency, the boiler reaches the national secondary energy efficiency standard. The fuel gas proportional type automatically adjusts the output size of fuel gas flow, and the hot water temperature maintains a constant temperature to meet the domestic hot water needs of customers.
★ This is an economical model with Heating and bathing function.
★ The heat exchanger adopts double channel oxygen free copper welding technology, with high efficiency.
★ The boilers apply Denmark Grundfos water pump,which runs quietly with longer serving life.
★ 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.
★ Intelligent three-level antifreeze function, automatic fault alarm and shutdown function ensures safe and worry-free use of the machine.
