Heating Q A Home boiler, why is the heating not hot

The above is the heating system caused by the heating system is not hot, and the following is an introduction to the causes and solutions of the heating caused by the radiator.

Radiator: If the heating at home is not hot or the heating is not hot, it is generally due to the fact that the outdoor water inlet and return valves are not opened; Locally not hot, possibly due to the fact that the top layer is not outgassed; The radiator is half hot and half cool, and the tail gathers air. In short, under the condition of ensuring the circulating pressure and temperature, the main reason why the heating is not hot is the air blockage, and the cohesive gas in the pipe can be released.

So how do you deflation the tube? Specific operation: There is a manual exhaust valve on each radiator, the user can gently loosen the manual exhaust valve, and immediately stop twisting the exhaust valve when he hears the exhaust sound, and if there is a steady flow of water out, the exhaust valve can be gently tightened.

If you accidentally break the exhaust valve, immediately find a wooden chopstick, sharpen one end, and insert it into the exhaust hole to avoid a large amount of water leakage. Then, find a professional to repair it. After exhausting, if the radiator is still not hot, you should ask a professional to find out the reason why the heating is not hot and help solve the problem, and you must not blindly discharge water.

St. Lawrence concludes by reminding residents not to let water out of the district heating system for use, as this can harm your health. Because the hot water in the central heating pipeline is the best medium for conducting heat energy in the fully closed circulation system at high temperature and high pressure, in order to prevent corrosion and rust of pipes and valves and ensure the smooth circulation of water supply and return during heating, a certain amount of chemicals are added to the water, and its water quality does not meet the domestic water standards at all. In addition, the release of water in the heating system will also cause serious water shortage in the heating system, make the pressure of the heating system unbalanced, and cause the local or full heating system to be unable to provide stable heat supply, affecting the normal heating.

Reason 1: The setting temperature of the wall-hung boiler is not high.

If the temperature of the wall-hung boiler is not high, the first thing to consider is whether the furnace outlet temperature is set too low?

The temperature of wall-hung boiler floor heating can be set to 30-60 degrees; The radiator heating can be set to a temperature of 30-80 degrees. Therefore, you can increase the setting temperature of the wall-hung boiler to change the indoor temperature.

Reason 2: The number of radiators is related.

In addition, it is related to the number of radiators. If the radiator is hot, but the room still doesn't feel hot, this is caused by too few radiators, so customers should also pay attention to match the size of the room when setting up the radiator.

Reason 3: There is air in the heating system.

If there is air in the floor heating or radiators, the heating effect will not be ideal. If you find that the wall-hung boiler works intermittently, and the heating system is hot and not hot, it is recommended that you find the exhaust valve of the heating system to exhaust it.

Reason 4: The occupancy rate of the building is related.

The occupancy rate of the neighborhood is also related, because "heat" has the characteristics of non-storage, and the amount of heat loss is inseparable from the occupancy rate of the community.

If a homeowner is full of occupancy, maybe the home can survive the winter without turning on the wall-hung stove; If there is no one in the neighborhood and the calorie consumption is high, it will not feel warm.

It is also closely related to factors such as the building itself. If it is a new building and relatively trendy, and the occupancy rate is not high, the gas consumption of the wall-hung boiler will be relatively large, and with the increase of the occupancy rate, the gas consumption of the wall-hung boiler will naturally decrease. After many people live in a new house, they will feel that the consumption of wall-hung boilers is high and the cost is high in the first year, but in fact, after living in a new house for two or three years, the gas consumption will naturally decrease.

Reason 6: The power of the wall-hung boiler does not match.

The building area is too large, and the power of the wall-hung boiler is relatively "virtual".

Most of the self-built houses in rural areas are two or three hundred square meters, with many doors and windows, and few protective layers, so it is difficult to lock the temperature; Moreover, the houses are relatively scattered, generally one or two storey bungalows, the population density is small, and the temperature is 3-5 lower than that of the city; The mismatch between the area of the house and the power of the wall-hung boiler leads to the fact that the radiator is not warm, and these reasons directly lead to the power of the wall-hung boiler is very "virtual".

The general reasons are:

1.The setting temperature of the wall-hung boiler is too low. If you find that the room is not hot, if the temperature is set too low, increase the setting temperature.

2.The number of radiators is concerned. If the radiator is hot, but the room is still not hot, it is caused by too few radiators.

3.Scale build-up, resulting in slow heating of the wall-hung boiler. Envoy.

1. The pipeline of the floor heating or radiator system is blocked. Floor heating or radiators can accumulate dirt after a long period of use. 2. The installation of heating pipelines is unreasonable and the heat dissipation is uneven.

Radiators should also be installed in the right quantity. 3. A large amount of air in the heating system is not exhausted. When the radiator or floor heating is running, gas is generated inside.

If the radiator is hot and the room is not hot, it means that it needs to continue to burn for a while. If it's been burning for a long time and it's not hot in the house, it means that your room is too big.

If the radiator is not hot, it is possible that there is air in the radiator. The air inside the radiator should be released.

The wall-hung boiler is burning, why is the heating not hot, the circulating pump is not started, and the hot water is not flowing.

The boiler heating is not hot, which may be caused by too much space and area in the room, or due to the poor airtightness of the room. Users can improve from the following aspects:

1. Accounting for the heat loss of the room: the heat loss of the room determines the power of the corresponding heating cable equipped with it, and the heat loss of a room includes the heat loss of ventilation, air intrusion heat loss and conduction heat loss (the sum of the conductive heat loss of exterior walls, ceilings, floors, doors and windows). The overall heat loss of the room is calculated according to the corresponding values, and then the appropriate type of underfloor heating is selected.

2. Determine the total power of the required device: use the calculated heat loss and multiply it by a correction coefficient to obtain the depicted power required for heating the room.

3. Calculate the floor area of the heating area: the floor area of the heating area is the practice pavement area of the geothermal cable, and the local area with indoor fixed equipment should be subtracted. Geothermal cables cannot be installed under fixed furniture such as wall cabinets, cupboards, bathtubs, fireplaces, etc., nor can they be installed under legless furniture such as sofas, beds, etc.

Note: There are many types of heating boilers, and their classification is mainly divided according to the fuel category, and heating boilers can be divided into electric heating boilers, oil-fired heating boilers, gas heating boilers, coal-fired heating boilers, biomass heating boilers, etc. Fuel includes:

Diesel, kerosene.

heavy oil, etc.; Among them, gas includes: natural gas, liquefied gas, city gas, biogas, etc.

First, the design and construction of the pipeline is wrong, which is the problem that the thermal balance of the pipeline system has not been adjusted well.

Second, there is a problem with the installation, make the main pipe road thicker, and then adjust the slope, the slope is different, the water flow resistance is naturally different, there may be some hot and some are not hot, and the radiator should be at the same height, so that it will heat up at the same time.

The condition of the insulation of the building. Buildings in many large cities in the north have adopted "three-step energy-saving" measures. Even if there is no heating facilities in the room that meets this thermal insulation standard, the indoor temperature can reach 13 15, and some small and medium-sized cities and rural new houses still mostly adopt the traditional building mode, and the two buildings have completely different requirements for the thermal power of the wall-hung boiler, that is, the former has lower requirements and the latter has higher requirements.

That can only mean that your home is not well insulated, or the heating is small.

It may be that the room is not well insulated.

Doors and windows are not well sealed.

The general reasons are:

1.The setting temperature of the wall-hung boiler is too low. If you find that the room is not hot, if the temperature is set too low, increase the setting temperature.

2.The number of radiators is concerned. If the radiator is hot, but the room is still not hot, it is caused by too few radiators.

3.Scale build-up, resulting in slow heating of the wall-hung boiler. The use of tap water can easily form scale, which causes the wall-hung boiler to heat slowly and the heating is not hot. Recommendation: Wash.

and other reasons, please call for consultation or repair for details.

Cause. The power of the heating equipment is not enough.

Solution: If there is no problem with the heating system itself, if the room is relatively large, it is necessary to increase the number of heating groups or pieces appropriately, if the number of installations is too small, the heat emitted by the heating can not be transmitted to every part of the room, and there will be a situation where the heating is not warm in the room.

Summary. Hello Dear I am glad to answer for you: the heating of the small boiler is not hot because the temperature of the boiling water has not yet come up, and the heat sink will only have heat after the water temperature in the boiler is raised.

The boiler water temperature is high, but the heating is not hot, indicating that the system circulation is too poor. It is estimated that it is a self-circulating earthen boiler, and the system is not circulating due to a problem with the installation of the system. Hope it helps.

You hail good dear I am happy to answer for you: the heating of the small boiler is not hot because the temperature of the boiling water has not yet come up, and the heat sink will only have heat after the water temperature in the boiler is raised. The boiler water temperature is high, and the heating chamber is not hot, indicating that the system circulation is too poor.

It is estimated that it is a self-circulating earthen boiler, and the system does not circulate due to the problem of the system installation source circle. Hope it helps. <>

Related information: The boiler is not hot, it may be that the boiler has been used for a long time, and the scale deposit in the boiler is too thick, which hinders the conduction of heat. It may also be due to the small size of the boiler and the number of radiators connected.

Mainly due to the fact that the combustibles in the stove provide a lot of heat, and the cracked water in the boiler absorbs the heat and provides the power of water circulation in the heating, but because the boiler is small, the power generated is also small, so the heating circulation is very slow. There is always a return of cold water in the boiler. Therefore, it will also cause the boiler to not burn hot.
