The use and advantages of condensing gas boilers

Condensing gas boilers, as modern, efficient, energy-saving and environmentally friendly heating equipment, have gradually become the main choice for natural gas energy-saving heating. It not only greatly improves operating efficiency, but also significantly reduces users' operating costs and brings considerable economic benefits. This article will explain in detail how to use a condensing gas boiler and its significant advantages.

How to use

Security check:
Before using a condensing gas boiler, a comprehensive safety check must be carried out. This includes checking whether each valve instrument is loose, whether the drain port and drain port are open, etc., to ensure that the various safety indexes of the boiler are at normal levels.
Water system connection and water filling:
After connecting the water system, inject water into the system and observe the water pressure changes on the pressure gauge inside the boiler. When the water pressure reaches the limited value range, stop water injection and check whether there is looseness or leakage at each waterway connection.
Power on and exhaust:
After turning on the power, press the power button to start the water pump and discharge the air from each heat exchanger coil. Or you can manually unscrew the manual exhaust valve at the front of the heat exchanger to exhaust. After exhausting, if the water pressure drops, water needs to be replenished until the water pressure reaches the working range.
Ignition operation:
After the smoke pipe is connected, connect the air source and perform ignition operation. Observe the red signal light on the sub-control board. The signal light will flash slowly after power is turned on, and will flash quickly after ignition is successful.
Parameter adjustment:
Under normal circumstances, the parameters of the condensing gas boiler have been adjusted before leaving the factory, and there is no need to make adjustments on site. However, if the local natural gas calorific value, air pressure or altitude changes, the combustion system must be analyzed and adjusted by professional technicians.

Advantages

High efficiency and energy saving:
The thermal efficiency of condensing gas boilers is as high as over 106%, far exceeding the domestic standard of about 94%. It recovers the heat energy in the flue gas by condensing the flue gas, greatly improving the thermal efficiency. The exhaust gas temperature is reduced to 5070°C, fully recovering the sensible heat in the flue gas and the latent heat of condensation of water vapor. Compared with traditional boilers (thermal efficiency is generally between 85% and 91%), it can save about 10% of gas.
Environmentally friendly cleaning:
The ultra-low carbon monoxide (CO) and nitrogen oxides (NOX) emissions of condensing gas boilers make them cleaner and more environmentally friendly, and can meet strict emission standards, such as Beijing’s 2017 boiler emission standards. More advanced condensing gas boilers use smokeless combustion technology, reducing nitrogen oxide emissions to more than 35mg/kwh.
Safe and reliable:
The condensing gas boiler is designed in full compliance with European safety requirements, and the combustion status is monitored throughout the process to eliminate the risk of excessive carbon monoxide. In addition, its powerful control system ensures that each boiler operates within an energy-saving range, increasing the safety of use.
Low exhaust smoke temperature:
The exhaust gas temperature of the condensing gas boiler is between 30°C and 70°C, and plastic pipes (such as PP, PVC) can be used, which further improves its energy-saving effect.
Precise temperature control:
Condensing gas boilers have precise temperature control capabilities, and the water temperature control accuracy can reach ±0.5°C, ensuring the comfort and stability of heating.
Economical and practical:
The high efficiency and energy saving characteristics of condensing gas boilers enable it to significantly reduce users' operating costs. In addition, due to its excellent environmental performance, users may also enjoy government environmental subsidies or preferential policies, further reducing usage costs.
In summary, condensing gas boilers have become the preferred equipment in modern heating systems due to their significant advantages such as high efficiency and energy saving, environmental protection and cleanliness, safety and reliability, low exhaust gas temperature, precise temperature control, economy and practicality. During use, users only need to operate according to specifications and perform regular maintenance and upkeep to ensure long-term stable operation and bring long-lasting and stable heating effects to users.
