Gas charging system What are the classifications of gas wall hung furnaces for software sharing? What should be paid attention to when purchasing?
Because of its flexible heating, energy-saving and comfortable characteristics, the wall mounted furnace is deeply loved by users and has entered thousands of households. The wall mounted furnace can not only provide heat for the family in winter, but also provide domestic hot water. One machine can be used for two purposes. But Brother Song wants to ask how much you know about the wall mounted stove? What are its classifications? What should be paid attention to when purchasing?
1. Classification by use
According to different uses, wall mounted furnaces can be divided into single heating type and heating/hot water dual-use type.
2. Classification by product specification and technology
According to the different product specifications and technical content, the gas wall hung furnace can be divided into conventional furnace and condensing furnace. The thermal efficiency of the condensing wall hung furnace is about 15-20% higher than that of the ordinary wall hung furnace, with energy saving up to 25% and low operation cost in the later period.
3. Classified by gas valve body
According to gas valve body, it can be divided into on-off type and proportional type. The on-off gas valve can not adjust the gas supply, only has the opening and closing functions; Proportional gas valve can be controlled by itself, with better energy-saving effect.
4. Classification according to the installation method of air supply and exhaust
According to the installation method of air supply and exhaust, it can be divided into 1~8 types. The domestic leading product is 1P type, that is, the appliance is connected to the terminal horizontally installed on the wall or roof through the supply and exhaust pipe. The supply and exhaust pipe can be coaxial pipe or separated dual pipe.
There are many types of gas wall hung boilers, and the following problems should be paid attention to when selecting them:
1. Thermal efficiency
It is important to know that the heat generated by combustion will be lost and cannot be fully utilized. Thermal efficiency represents the effective utilization rate of heat and represents the energy conservation of products. Products with high thermal efficiency consume less fuel while obtaining the same amount of heat. We should try to choose products with high thermal efficiency to save fuel and reduce operating costs. The thermal efficiency of conventional wall hung furnaces can generally reach 85%~91%, and that of small squirrel wall hung furnaces can reach more than 107%.
2. Rated output power
Rated thermal output power is divided into z large rated thermal output power and z small rated thermal output power.
