The rain is coming, the weather rainfall begins to increase gradually, after the beginning of spring, there is still some cold in the northern region, and the central heating will stop around March 15, so the use of wall-hung boilers has also begun to enter the end of the heating season. In the north, under the baptism of several heavy snowfalls, the chill is coming again. At this time, at the moment when the wall-hung boiler is about to be closed, it is necessary to do some strategies for anti-freezing in the case of heavy snowfall.
First of all, let me briefly talk about some principles of wall-hung boiler: the heating system of wall-hung boiler is a water circulation system, when the temperature drops in winter, when the temperature in the pipeline drops to freezing, it will lead to the rupture of the waterway pipeline, which will not only affect the normal heating, but also produce high maintenance costs. So what should be done about this seemingly intractable problem? In fact, major brand manufacturers have begun to have good countermeasures for the anti-freezing of wall-hung boiler products.
As a heat source device that integrates water, electricity and gas, and can provide independent heating and domestic hot water, the wall-hung boiler will automatically enter the antifreeze mode under normal circumstances. Taking the NCB700 of the fully premixed condensing wall-hung boiler in Gyeongdong Nabian as an example, multiple antifreeze technologies are used in the design, which can maintain the normal and stable operation of the wall-hung boiler in the low temperature and cold environment of -40.
For the wall-hung boiler with antifreeze function, it will be easier and more comfortable to use in winter. For wall-hung boiler products without antifreeze function, in winter, especially during the Chinese New Year, it is inevitable to visit relatives and friends, walk back and forth, sometimes far away, sometimes short. On the basis that wall-hung boiler products do not have anti-freezing function, it is necessary to master a certain anti-freezing operation of wall-hung boiler products to do a good job in anti-freezing of wall-hung boiler products.
First of all, we divide the length of travel time and make a simple explanation of different use experiences in different scenarios based on the gas consumption and anti-freezing risk of wall-hung boiler products
When returning home for the Spring Festival or traveling for a short period of about a week, it is necessary to do a good job of indoor insulation, close doors and windows in advance, and prevent the indoor temperature from being too low and freezing the radiator and pipeline system. There is no need to turn off the power of the wall-hung boiler, and the heating temperature can be lowered to maintain a certain temperature in the room and avoid damage to the equipment.
For families whose homes have been uninhabited for a long time (more than a month), or who have not moved in after the renovation of a new house, it is particularly important to protect the freeze of wall-hung boilers and heating systems. Completely empty the water in the pipes of the wall-hung boiler and heating system, and cut off water, electricity and gas to avoid the freezing and expansion of the heating system and the wall-hung boiler system caused by sudden power outages and gas outages in winter, which will cause water leakage accidents in the heating system.
