How about the thermal efficiency of Guanglei coal-fired heating furnace?

The thermal efficiency of Guanglei coal-fired heating furnace is not bad. It adopts various advanced thermal efficiency and energy-saving technologies.

Intelligent control: microcomputer control is adopted to realize the functions of automatic constant temperature, automatic start and automatic temperature rise, without special management.

Energy-saving and environmental protection: adopting coal storage three-effect anti-combustion technology, increasing water capacity, prolonging flue gas flow, large heat absorption surface, high thermal efficiency, environmental protection and energy saving.

Powerful: It has two functions (radiator and floor heating) and three modes (comfort, warmth and economy), and users can change them at will as needed. With automatic power-off storage function. With anti-freezing function, the water pump runs automatically at low temperature to prevent the system from freezing at low temperature.

Advanced technology: the quick-opening ash cleaning structure makes the ash cleaning more convenient and keeps the boiler in the heat exchange state of the new furnace. Adopt integral heat preservation, with novel appearance and small heat loss of boiler. Adopt a number of independent patented technologies, ranking at the advanced level at home and abroad.
