In the boiler, how to understand the "atmospheric pressure" and "pressure" these two concepts?
Another typical feature of the fuel gas pressure hot water boiler is: the heating system of the circulating water pump is generally selected water pump, it is pumping system engineering backwater to the boiler, it is necessary to overcome the system cycle resistance, but also to maintain a certain boiler
Pressure hot water boiler can supply both low temperature water, but also supply high temperature hot water.
Fuel gas The pressurized hot water boiler is a pressure vessel, which must be fitted with a pressure gauge, a safety valve and a thermometer.
In the boiler, "atmospheric pressure" refers to the same with the atmosphere, not pressure, "pressure" refers to the pressure.
Pressure, to ensure that high temperature hot water is not vaporized.
