The water temperature of the wall hung boiler is set at 45 degrees Celsius and 50 degrees Celsius, a

The temperature in the machine is set by the main control board, and the user can not change it by the after-sales professionals with the jumper setting.

Less than 50 degrees indoors. When the ignition switch of the wall-hung boiler enters the working state, the fan starts first to form a negative pressure difference in the combustion chamber, the wind pressure switch sends the command to the water pump, and after the pump starts, the water flow switch sends the command to the high-pressure discharger, and the command is sent to the gas proportional valve after starting, and the gas proportional valve starts to start.

The gas proportional valve and the wind pressure switch and the flue gas induction switch are interlocked, the combustion chamber has a certain negative pressure gas, the proportional valve can work, when the flue gas induction switch can not detect the exhaust gas discharge in 5 seconds, the gas proportional valve will be cut off to stop the gas supply, so as to ensure the safe use of gas.

Product type. Gas wall-hung boiler.

In the decades since the birth of wall-hung boilers and into the commodity era, a variety of wall-hung boilers with various structural properties have emerged in the HVAC product markets of various countries, including China. The types of these wall-hung boilers are roughly as follows:

1. According to the heating method, it can be divided into instantaneous wall-hung boiler and volumetric wall-hung boiler;

2. According to the use, it can be divided into single-function and dual-purpose heating and bathing type, of which the dual-purpose heating and bathing type can be divided into casing wall-hung boiler and plate-swapping wall-hung boiler.

3. According to the characteristics of the gas valve body, it can be divided into on-off wall-hung boiler and proportional wall-hung boiler.

4. According to the pressure characteristics of the combustion chamber, it can be divided into positive pressure combustion wall-hung boiler and negative pressure combustion wall-hung boiler.

5. From the form of heat exchanger, it can be divided into internal combustion wall-hung boiler and external combustion wall-hung boiler.

6. According to the characteristics of the circulation system, it can be divided into open wall-hung boiler and closed wall-hung boiler.

7. According to the characteristics of waste heat, it can be divided into ordinary wall-hung boiler and condensing wall-hung boiler.

Set a 50-degree holding time for a long time. Before use, the user should check whether the water pressure gauge pointer of the boiler is within the specified range, and the standard water pressure specified in the manual is.

During winter heating, it is normal for the water in the heating system to expand when heated, and the water pressure in the system will rise, and then drop when the water cools. Experiments show that as long as the water pressure in the wall-hung boiler is kept in between, it will not affect the normal use of the wall-hung boiler at all.

If the water pressure is lower, it may cause the domestic hot water to be hot and cold or not start normally, if the water pressure is higher, the system pressure rises during heating, if it exceeds 3 bar, the safety valve of the boiler will automatically drain water.

Set 50 degrees to keep warm, and of course keep it longer. But also to burn a little more gas. It doesn't matter how many degrees he has, as long as he is comfortable with it.

Wall-hung boilerAdjust to 35 degrees Celsius, and the actual temperature has 20Celsius

The temperature of our daily wall-hung boiler boiling water is best around 50, and the boiling water at home in the coldest winter is generally not more than 53 degrees, of course, if the wall-hung boiler with the calendar is more advanced, it is best to circulate between 42 and 50 degrees within a certain period of time.

There is generally no scale in the wall-hung boiler, but when the boiling water temperature of the wall-hung boiler is too high, the generation of scale will increase a lot, because the generation of scale is increased with the increase of water temperature, once the water temperature is too high, the increase of scale will also cause the service life of the wall-hung boiler to be affected.

Household wall-hung stove Note:

1. Installation of gas pipelines: The connection of wall-hung boilers and gas connection pipelines must be installed and debugged by trained professionals. The main point is to use gas pipes and clamps that meet safety requirements.

Secure it to prevent it from falling off. It is strictly forbidden to transfer gas pipes and gas meters.

Shut it up. 2. Leakage inspection of gas path: from the gas meter interface to the interface of the gas valve section of the wall-hung boiler to the fire discharge, any connected interface must be tested for air tightness before it can be used.

3. Inspection and replacement: According to the quality of the gas hose, it needs to be replaced regularly to prevent the danger of gas leakage caused by aging and cracking of the hose. If the special aluminum-plastic pipe for gas is used.

Or a new type of stainless steel gas pipe or a zinc-plated iron pipe, which is a relatively one-and-done choice.

Wall-hung boilerSet the domestic hot water, the temperature is recommended to be set between 40-50; It can be set at 50 degrees in winter and 40 degrees in summer.

It is not recommended to set the temperature too high, because the water pipes at home are made of PPR material, and if the temperature is too high, it will have a certain impact on the life of the water pipes. Secondly, when the water temperature exceeds 60, the wall-hung boiler continues to work under overload, which will directly affect the service life, and at the same time, the possibility of internal fouling will increase, and if the fouling is done, it will also have an impact on the heat exchange efficiency of the equipment.

Heating temperature: 1. Radiator heating.

Radiator systems, due to the characteristics of their radiators, it is recommended to set the temperature at 50 60 .

2. Floor heating.

It is appropriate to set the water supply temperature at 45, which can bring the room temperature to around 20, which is a relatively comfortable temperature.

System blockage: When the wall-hung boiler system is blocked, the water circulation will stop, and then the water exchange temperature in the main heat exchanger of the wall-hung boiler will soon exceed the set temperature, but the water cannot circulate normally, and even lead to the high temperature failure of the wall-hung boiler.

Air inside: There should not be too much air in the wall-hung boiler system, as too much air will cause the temperature of the heat exchanger to rise to a very high temperature very quickly, or even reach the set temperature after a while.

It depends on the indoor area and the size of the wall-hung boiler, as well as the strength of air fluidity, which will affect the temperature, and the general building, the wall-hung boiler is more than 40 degrees, and the temperature will be dry no matter how high it is.

Working principle: when the ignition switch of the wall-hung boiler enters the working state, the fan starts first to form a negative pressure difference in the combustion chamber, the wind pressure switch sends the command to the water pump, and after the pump starts, the water flow switch sends the command to the high-pressure discharger, and the command is sent to the gas proportional valve after starting, and the gas proportional valve starts to start.

The gas proportional valve and the wind pressure switch and the flue gas induction switch are interlocked, the combustion chamber has a certain negative pressure gas, the proportional valve can work, when the flue gas induction switch can not detect the exhaust gas discharge in 5 seconds, the gas proportional valve will be cut off to stop the gas supply, so as to ensure the safe use of gas.

system clogging: when the wall-hung boiler.

Water circulates after the system is blocked.

It will stop, and then the water exchange temperature in the main heat exchanger of the wall-hung boiler will soon exceed the set temperature, but the water cannot circulate normally, and even cause the high-temperature failure of the wall-hung boiler.

Air inside: There should not be too much air in the wall-hung boiler system, as too much air will cause the temperature of the heat exchanger to rise to a very high temperature very quickly, or even reach the set temperature after a while.

22℃。

It should be noted that when using geothermal heating, the surface temperature should not exceed 28 ° C, and the water pipe temperature should not exceed 45 ° C. If this temperature is exceeded, it will affect the service life and longevity of the floor. Usually, in winter, the room temperature reaches about 22 ° C.

If the temperature rises normally, it will not affect the use of the geothermal floor.

When using geothermal heating for the first time, be aware that the temperature rises slowly. When using it for the first time, the temperature should be gradually increased within the first three days of heating: the water temperature on the first day is 18, the water temperature on the second day is 25, the water temperature on the third day is 30, and the room temperature can be raised on the fourth day, that is, the water temperature is 45 and the surface temperature is 28

Do not heat up too quickly. If the speed is too fast, the floor may crack and twist due to expansion. When reactivating the geothermal heating system after a long period of time, the temperature should be raised strictly according to the first heating procedure.

50 degrees from the perspective of wall-hung boiler gas saving, the lower the wall-hung boiler temperature setting, the more gas-saving, generally speaking, the temperature will consume more energy for each degree of increase in energy 5, but the temperature of the wall-hung boiler can not be too low, so that the heating effect will not be achieved.

If you consider the two methods of comfort and gas saving, it is recommended that the room temperature is set at about 20 degrees, the water temperature of the wall-hung boiler is set between 60 and 80 degrees, if you are using floor heating, you can set 60 degrees, if you are using a radiator to heat, you need to set 70 to 80 degrees.

If you bring a radiator, you can set it to about 70, try to burn it, and adjust it according to the actual temperature of the room. If it is connected to the floor heating, it can be adjusted to 40 degrees Celsius, and the maximum temperature of the floor heating should not exceed 55, otherwise it will affect the service life of the floor heating pipe.

It will rise above 45 to stop and drop to 35 to restart. It is generally a 5 fluctuation difference of the set temperature. If it can burn all the time around 45, it is the best, which means that the fire power and temperature control are accurate.

If the wall-hung boiler is set to 40 degrees, but the actual temperature reaches 50 degrees, then you can take the next step

1.Check whether the temperature setting of the wall-hung boiler is correct. If the set temperature is 40 degrees and the temperature reaches 50 degrees, it may be caused by an incorrect set temperature setting. You can reset the set temperature to make sure it matches your needs.

2.Check whether the temperature controller of the wall-hung boiler is normal. If the wall-hung boiler is set correctly, but the temperature still exceeds the set temperature, then there may be a fault with the temperature controller. You can contact a professional repairer for overhaul and maintenance.

3.Check whether the radiator of the wall-hung boiler is normal. If the temperature of the wall-hung boiler is too high, it may be caused by a faulty radiator. You can check the radiator for blockage or damage, and clean or replace it in time.

4.Reduce the use time of wall-hung boilers. If the wall-hung boiler is used for a long time, it may cause the temperature to be too high. You can reduce the use time appropriately to avoid excessive temperatures.

In conclusion, if the temperature of the wall-hung boiler exceeds the set temperature, measures should be taken to deal with it in time to avoid safety problems. If you are not sure how to deal with it, it is recommended to contact a professional service person for service and maintenance.
