Low-nitrogen condensing wall-hung boilers, with Danish Grundfos circulating water pump which runs quietly and the circulation performance is excellent. This product has already obtained the national patent, with the patent certificate number of ZL201530085073.0 and ZL201821497031.2. The thermal efficiency of the secondary heat exchange and condensation in the stainless steel coil is as high as 99%, which reaches nationally certified primary energy efficiency. Enhanced low-temperature combustion technology can lower nitrogen emissions and be more environmentally friendly. Unique anti-corrosion layer and condensate water treatment technology extend the service life of the machine.
★ The boilers reach to primary energy efficiency, with lower nitrogen emissions and being more environmental friendly.
★ Adopting condensers with stainless steel tube，which could realize twice water condensing, ensures lower exhaust temperature.
★ The boilers apply Italy G20 waterway system and integrated waterway module design.
★ The boilers apply Denmark Grundfos regulating water pump，which runs more quietly with better circulating performance.
★ Adopting die-casting aluminum and variable speed draught，the boilers runs more quietly with high efficiency.
★ Timing function is set Internally to meet different needs for heating.
★ It can be connected with indoor and outdoor thermostats, which is convenient，energy-saving and worry-free.
★ Multiple safety protection ensures safe and reliable operation.
★ Intelligent three-level antifreeze function, ensures safe and worry-free use of the machine for the whole winter.
★ The boilers are with remote WIFI control function，making heating more convenient and worry-free.
