Automatic hot air heater works:
Air to water heater operation, automatic control thermostat; turning on the power, set the machine operating temperature. The machine automatically enters a heated state, when the heat reservoir temperature equal to the set temperature, the machine stopped working, enters the standby state; over time when the temperature probe detects heat reservoir temperature below the set temperature of 3 ℃, circulation pump to work, hot water heating into the host again heated until the water temperature reaches a predetermined value, the insulation system to stop working, the machine into standby mode; due to the use of the user, when the heat reservoir refilled with cold water, the machine re-enter the heated state, and so forth cycle.

Hot water engineering applications:
Hotel hot water, kitchen water, hot water factory dormitory, small farms hot water, hot water production in warm regions.
