Vacuum Hot Water Heating Boiler

Vacuum hot water boiler is an ideal solution for heating supply, gas and oil are available to be used in the heating boiler. There is completely deoxy purified water in the furnace, so there is no corrosion and incrustation. Working in the negative pressure, vacuum hot water boiler has zone explosion in record.

High efficiency

Such series boiler adopts three pass structure and wet back reversal chamber structure. Besides, it uses high-quality aluminum silicate to preserve heat to make the heat loss of the machine fall down to limit value and the overall thermal efficiency up to 92%.

Widely application

One boiler can be equipped with several heat exchangers for supplying hot water with different temperature and different application. For example, the water for central air conditioning, sanitary hot water, hot water processing etc.

100% safety, zero explosion

The pressure of the medium circulation system is lower than the atmospheric pressure and the inner absolute pressures from 0.02 to 0.08MPa when the boiler in the operation condition, which keep the unit in the vacuum status, so that the boiler running safely without explosion.

Long operating life

There is no incrustation inside the boiler to increase boiler’s service life which is 1.5 to 2 times than ordinary boilers.
