Gas-fired vacuum hot water units and gas-fired vacuum hot water boilers are all vacuum equipment, which have the characteristics of safety and no explosion risk, and can also output high-temperature hot water. However, there is still a clear difference in performance between the two.

The difference between these two types of equipment is generally reflected in the control and management of the equipment and the operational requirements of the operators. And, comparing these two, gas vacuum hot water boiler is better than gas vacuum hot water unit, the specific reason we also see below.

The gas-fired vacuum hot water boiler works by using the characteristics that the boiling temperature of water is different under different pressures. At an atmospheric pressure, the boiling temperature of the water is 100 ℃, and the vacuum hot water unit is operated within a pressure range of -0.02Mpa, and the corresponding heat medium water temperature is lower than 93 ℃. Under pressure, combustion raises the temperature of the heat medium water to saturation temperature and produces steam of the same temperature on the water surface.

The gas-fired vacuum hot water boiler adopts a unique condensation technology, so that the boiler's operating efficiency can reach 107%. Everyone has doubts here, can the operating efficiency exceed 100%? In fact, the gas vacuum hot water boiler can make full use of the boiler's own operating efficiency and the high temperature heat carried in the flue gas discharged, and then put it into the boiler for recycling, so that the boiler's operating efficiency can reach 107%. For enterprises using this type of equipment, the use of gas-fired vacuum hot water boilers can save at least tens of thousands of yuan to hundreds of thousands of yuan in fuel input costs.

Moreover, the gas vacuum hot water boiler uses gas fuel, plus the full premixed combustion technology, the gas fuel is pre-mixed with the combustion-supporting gas (that is, air) before being put into combustion, and then reaches the precise ratio before participating in the combustion. The fuel can be fully burned, the emission of nitrogen oxides is also reduced, and the environmental performance is more excellent.

Through various comparisons, it is enough to see that the overall efficiency of the gas vacuum hot water boiler is higher than that of the gas vacuum hot water unit.
