When the water temperature reaches the upper limit of the set water temperature, the burner stops working, and the boiler enters the automatic insulation state, and the user can continuously connect the pure boiling water from the boiling water outlet. The gas boiling water boiler can also be connected to the insulated water tank to meet the boiling water needs of centralized water supply units such as hospitals and schools. Gas boiling water boiler, also known as gas boiling water boiler, gas drinking water boiler, gas tea boiler, gas tea stove, etc., is a kind of life boiler, belongs to the category of atmospheric civil boiler, and the design, manufacture, installation and use of gas boiling water boiler are not subject to the supervision of the technical supervision department.

Hot water boiler parameters refer to the heat power, outlet pressure and supply and return temperature of the boiler.

When the thermal power (heat supply Q) hot water boiler is running safely for a long time, the water output per hour can effectively carry heat. That is, the thermal power of the boiler, expressed by "Q", is measured in megawatts (MW), and the engineering unit is 104 kilocalorie-hours (104 kcal h).

The working pressure refers to the maximum allowable pressure of the boiler. The working pressure is determined based on the design pressure and is usually expressed in MPA.

Outlet water temperature: refers to the temperature that the water temperature at the outlet of the boiler can reach under the condition of various predetermined design parameters.

Return water temperature: The return water temperature refers to the temperature of the circulating water in the heating system at the inlet of the boiler or hot water heater.
