- Heat up by electric heater, no hazard exhaust, sanitary, healthy and zero pollution.
- No exhaust heat loss, maintain long-term efficiency.
- Sophisticated design, neat in appearance, and small in size.
- Electric leakage detection design, which automatically detect electric leaking heater, display the position and stop operating without effect other heaters' function. Safety guaranteed.
- Complete installed all safety devices, safety valve, pressure switch, pressure gauge, and prevention of idle combustion.
- Electric heaters start in sequence, which maintain steady current instead of abrupt current.
- Water insufficient detection : microcomputer automatically operating detection, it prevents idle boiler combustion and detection of broken and deteriorate water pump.
- Water level control abnormal detection : microcomputer automatically detects, which effectively prevents water level electrode disconnect, short circuit and breakdown caused by water scale.
- Easy to operate, microcomputer self-check and report faulty position.
