Comparison of mixing center and decoupling tank

1. The ground heating on the first floor is not hot, and the heating on the second floor is hot, which indicates that the heating system circulation is good on the second floor, and the first floor can not circulate normally in the heat source pipe network
the floor heating and radiator are mixed in one system, because the hot water temperature required by the heating is high, the hot water temperature required by the floor heating can not exceed 60 degrees, and the coupling tank is required to balance the water temperature and pressure for the balanced operation of the heating and floor heating. Therefore, the installation of radiator and floor heating in compound floor has high requirements for construction technology. If the operation is not good, the temperature will be uneven. During the construction, attention should be paid to the system pressure balance, the difference of water supply temperature between upstairs and downstairs, and the circulation of heating water
solution:
1. Turn off the radiator on the second floor, let the system on the first floor heat first, and then turn on the radiator on the second floor
2. Open half of the radiator valve on the second floor to feed the external water pump (water mixing device) on the first floor to increase the circulation speed of ground heating on the first floor
3. Add water mixing system and decoupling tank.

2. Is there a mistake? Take a picture. In addition, is the water temperature set low

3. There are many reasons why the radiator is not hot, such as the problem of your installation location, the size of the radiator, the problem of water outlet of the boiler, whether the radiator pipeline is blocked, the problem of water pressure, whether the pipeline is relatively small, resulting in small water flow, etc. it is suggested that you go to the installation company to have a look. The system is made by them and can be solved. Shure floor heating measures the room free of charge, Offer a plan

4. Water mixing tank is a kind of device used for mixing cold and hot water. It is equipped with drain valve and automatic exhaust valve. It is a high-end floor heating water mixing system, which is widely used in wall mounted boiler system
the mixing tank can make the primary cycle and secondary cycle run independently. The flow rate of each circulating system only depends on the technical parameters of its own pumps, so as to avoid the interference caused by the series connection of pumps
the all copper water mixing tank is an integrated device of water mixing tank and water pump, which is easy to install without debugging
it can save more than 25% gas.

5. Zhou Gong, only the Weineng can be called decoupling tank, the others are called mixing water

6. Decoupling tank, commonly known as water mixing tank, refers to the use of water system heating, e to the existence of hydraulic coupling between the circuits, when a branch or user's flow changes, the flow of other branches or users and the boiler's flow will be affected, so that the water balance of each cycle circuit is broken. The decoupling treatment is carried out by using a device which creates an area with almost zero pressure loss to make the pumps realize their own circulation, mutual non-interference and heat transfer without loss. The device is called decoupling tank. Function and function of decoupling tank: the user can adjust the temperature of each room by using electric temperature control valve or manual temperature control valve, which causes the change of flow and pressure in the heating system. The function of decoupling tank can balance the pressure in the wall hanging furnace system and the heating system, and has no effect on the flow of the wall hanging furnace system; On the other hand, for the closed small boiler heating system, the application of decoupling tank can avoid the energy waste caused by the frequent start-up of the boiler and protect the boiler; Second, the installation of decoupling tank in the floor heating system can realize the technical advantages of large flow and small temperature difference of the floor heating system, and it is the first choice for wall mounted furnace and prefabricated thin floor heating system.

Lotus pot is to eliminate the coupling effect, not to mix water to cool down, no need to set the temperature. If there is no water mixing center, the wall mounted furnace doesn't need to turn on such a high temperature. The water supply temperature of floor heating is 40-50 degrees. In the case of meeting your indoor temperature, the lower the water temperature set by the wall mounted furnace, the more energy saving

if there is a water mixing center, the wall mounted furnace can be set at 60 ℃, and then let the water mixing center cool down and enter the floor heating pipeline. Similarly, the lower the water temperature set in the mixing center is, the better
