Van de Lee condensing direct fired module boiler

Condensing direct fired boiler, the leader of the new standard.

The thermal efficiency 102%-105%; no noise, normal operation can not hear the sound; almost no electricity, 0.0013 hours per hour; gas civil pressure can work normally, the opening cost is low; ignition heating synchronous, heating speed is super fast.


Van de Lee direct fired module boiler

Warm - silent

The high efficiency heat exchanger will save about 30% energy. Normal operation can not hear sound and consume 0.001 degrees per hour. The domestic gas pipeline network system can run normally, and the opening cost of natural gas is low. According to the outdoor temperature in winter, start on demand and alternate with each other to eliminate energy waste. It can prevent dry burning, flameout, gas outage, power failure and temperature intelligent protection. It can be operated with one button, without training, and can be operated safely and reliably.
