This product adopts the brand new horizontal and inner intensified-heating-tranmitting design, the ideal symmetrical structure and very big hearth radiation area as well as the vertiginous current fire tube promote the heating efficiency and can be used in small space, which is an advantage comparing with similar products on the market. Additionally, the full-automatic boiler electro-control case designed to made with imported noted-brand electrical components that feature good durability and suitable for China's situation that the power supply is unstable sometime.These design has been recognized and highly praised by the clients in over 10 years of engineering application.
　　The security of the product has been approved by National Gas Appliances Quality Supervision & Examination Center, an authority national department in this field.
　　·Boiler features
　　Free boiler
　　The most fashionable 3-stroke wet-back central back-burning mode in Europe and America is adopted. And the chamber bulged freely to prevent the thermal stress, ensure the security and reliability.
　　Exhaust gases runs
　　The burning exhaust gas enter the chimny from vertiginous current smoke tube for secondary heating. This not realized high-performance energy-saving but also convenient for deashing.
　　Forced circulation
Water circuit with obliged run
The back-flow water supply circulated along forced route. The cool or hot water are prevented to enter the pipeline network directly.
High-efficiency warm-keeping
High-effectiency heat insulation
The boiler adopts excellent light ultra-thin glass wool and is covered by high-temperature baking-vanished guard board which reduces heat loss and promote the heat efficiency.
Boiler manufacture
Made according to GB JB/7985-95 criteria with excellent GB boiler steel plate.
Flexible boiler fire door
Door with total adjustment can be opened from both sides, left or right, and easy for upper and lower regulating and maintenance. In door sealing, carbon fibre and ceramic fibre, the hi-tech material used in aviation engineering are used to knitting the seal gasket.
