WNS series gas fired hot water boiler, the use of horizontal wet three return back float furnace structure, combustion chamber adopts corrugated furnace, and a low arrangement, and maximize the increase of radiation heating surface, all of the flue gas channel under the water, the tail is equipped with a waste heat water tank, and perfect insulation outsourcing design, boiler thermal efficiency is above 95%, the smoke temperature 50 ℃ (general boiler thermal efficiency is 86%, the smoke temperature 170 ℃).The product design is novel, the structure is reasonable, the craft performance is good, the safety is reliable, at the same time has the occupation area small, saves the energy, the environmental protection performance is good characteristic.

Boiler Features:

1.Monitoring of water level: Equipped with water level electronic detector to control the water level.

2.Setting time: The users can set the starting and stopping time as their demand.

3.Electric leakage protection: When the elements of boiler have a electric leakage, the control system will cut off power automatically.

4.Water shorage protection: When the boiler is lack of water, the system will turn off burner and raise alarm.

5.Over pressure protection:When the pressure of boiler is over your setting point, burner will stop working and raise alarm.

6.Power abnormal protection:When the power ia abnormal, the boiler will stop working immediately.
