My family lives in a rural area. I built a three-story house myself because the winter in the north is cold, I have to heat it myself. But when heating the radiator system, the first and second stages are hot, but the temperature on the third stage is not high. So what happens when the heating temperature on the third floor is not high, and what happens with Brother Jinqiangqi?
In this case, it is most likely a stress problem. In other words, the hot water pressure after reaching the third stage is very low, and the temperature of the third stage is not high due to the failure of normal supply and return circulation some water. For this reason, I would like to offer you the following solutions.
①: The first thing we need to do is check the heating situation on the third floor. There are three things to do here. All of abord, we evacuate the entire third floor heating system to make sure there is no gas. Since the third floor is a high-rise building, it is easy to get gas. If the problem still cannot be resolved after exhaustion, clean the three-layer filter to ensure that the pipes and heating system are not clogged. Finally, we measured the heating pressure of the three stages. According to the actual situation, continue to follow the steps below.
②: Adjust the water supply and return pressure. For example, our indoor heating uses a gas wall boiler heating system, and the gas wall boiler comes with heating for the first, second and third floor. At the moment, there is no problem on the first and second floors, but after reaching the third floor, the temperature cannot rise. This means that the pressure that n can bringOur wall-mounted gas boiler can only satisfy the heating of the second floor. So at this time, I personally suggest you first see if you can adjust the water supply pressure of the wall-mounted gas boiler. For example, the pressure of the three-layer heater must reach at least 0.3 MPa to meet the demand. You can find a gas wall boiler manufacturer to handle this.
③: Install the booster pump separately. In other words, if the heating installations in our house are already fixed, that is, the pressure value has been set to a high value and can no longer be adjusted, then at this point I personally recommends that you install a separate booster pump. Concerning the lift of the booster pump, I personally recommend that you choose a lift of around 25m. In this way, this booster pump serves to provide heat from the 1st to 3rd floors of our homes. At this stade, the booster pump and the circulation pump must cooperate to achieve good working effect.
④: Adjust the pressure of the circulation pump. As for the circulation pump used in floor heating, in addition to having the function of flow circulation, many circulation pumps also have a certain pressure. We can therefore now examine the pressure of the circulation pump of the heating system we have installed. For example, if the pressure at this time is only about 0.20 MP, it should not be able to reach the third level. You can see if it can be adjusted to 0.3 MPa, which can meet the water supply and return needs of our three-layer heating.
⑤: Adjust the water supply and return circulation method. For example, if the temperature on the first and second floors meets the requirements, but the temperature on the thirdme floor is not high, the heating method adopted at this time should be from bottom to top. That is to say, start with the first stage, then move to the second stage, then the third stage, so that the pressure gradually decreases. If we can make adjustments to provide for the main water return pipe, modify it to provide heat from the third stage and then gradually to the second and first stages. That is to say, the main pipe is directly connected to the third floor and then returned to the first floor. It can also solve the problem of the third floor not being hot.
Operation suggestions: ①. When we find that the heating situation in the house is that the first and second floors are hot and the third floor is not hot, I personally suggest you first measure the temperature of the water supply and return to the first, second and third stageges. In addition to rolling pressure, our goal is to measure pressure. ②.We check and adjust the pressure value of the circulation pump or pressure pump according to the pressure of each layer to meet the pressure requirements of each layer. ③. If the heating installations we use cannot adjust the pressure, it may be necessary to add a pressure pump again to meet the pressure demand.
What issues should we pay attention to when installing heating at home?
For self-installed heating in a house, you generally need a heat source and heater at the back of the room, then a circulation pipe between the heat source and heating device. For these, strict calculations must be made for selection and installation. For this reason, I personally suggest that youpay attention to the following three questions.
①: The selection of equipment and the installation of pipelines and heating installations should be selected after strict design calculations. Because at this stage, many families directly purchase wall-mounted boilers and install them, and then arrange the pipes arbitrarily, resulting in poor heating effect in the later period. And if we find a professional manufacturer to design and then select the models, we can avoid this problem.
②: After the heating installations are installed, they need to be debugged. Heating installations here include heat sources, pipelines and terminal heat dissipation installations. After the installation of the entire heating system is completed, we need to debug it under normal use conditions. At this point we need to test the debit circulation of water supply and return, the pressure of each layer and the operation of the whole equipment to prevent the final pressure from being too low and affecting the heating.
③: When selecting equipment, we must make a selection according to our specific indoor conditions. There are mainly two very important parameters here: one is the value of the thermal load and the other is the circulation flow rate. Another point is its pressure value. That is to say, all these parameters must meet our heating needs in order to meet indoor heating requirements.
