Is it okay to adjust the heating and hot water pipe up to two meters without a circulating pump?

Personally, I think that if the heating and hot water pipe is raised by two meters, there is no need for a circulating pump. Specified below:

It is determined by the pressure of the room heating system. For the working pressure of the home heating system, it is usually megapascals, which is what we often call 4 kg. In the case of 4 kg, you may not know what it means.

Convert to a column of water. Such a pressure can bring the water up to 40 meters high. Of course, along the route and local losses are not calculated here, so it is also under great pressure.

The pipes of the indoor heating system rise by 2 meters. The resulting pressure affects megapascals, i.e. kilograms. For this pressure, the impact on our indoor heating system is minimal.

This means that even if we raise the pipe by 2 meters, the pressure inside our water supply and return pipes can be reduced to megapascals. But the reduced megapascals do not affect the normal ** return cycle of our indoor heating.

In fact, another scenario can be seen. That is to say, there are other ways to arrange indoor heating, such as the lower supply, the lower supply, the lower supply and the lower back.

For example, our upper and lower back pressure pipes are arranged in such a way that the water supply pipe is above and the return pipe is below, so that the difference between the two is more than two meters. If we change it to the next time, it can also be used normally. Therefore, the change in the height of the indoor heating duct will not affect the operation of the system.

Comprehensive analysis: 1. For the indoor heating system, as long as we can ensure the normal working pressure, we will not be greatly affected after renovating the indoor heating pipeline. 2.

The rise of the indoor heating pipe does not affect the pressure difference of the total return water of the pipe. This is because the pressure of the pipe in the opposite direction will also decrease at the same time after the heating rises. Therefore, there is no need to install a circulating pump at this time.

If our indoor heating is not good, and we find that there is no pressure difference between the return water, then we need to consider whether to install a circulating pump. There are other issues to be aware of. **In the case of heating, it is practically not possible to change the indoor heating facilities.

In particular, it is strictly forbidden to install a circulating pump in the home personally.

No. Without a circulating pump, the water still can't be delivered. The water for heating is circulating, no matter how high the hot water pipes are, to ensure circulation, it is necessary to use a circulating pump.

It is possible to do without a circulating pump, because the pressure of 2 meters rises to a megapascal value, which still does not affect the normal ** return circulation of indoor heating.

Personally, I think that if the heating and hot water pipe is raised by two meters, you can do without a circulating pump, you only install the water supply pipe, put some water when you use it, and the hot water will pass.

If the heating pressure is not enough, you can not install the circulating pump without authorization, in fact, this behavior is illegal, in violation of the provincial and municipal heating regulations.

Taking Shandong Province as an example, according to the "Shandong Provincial Heating Regulations", it is stipulated that:

Article 32 Users shall properly use and maintain their own heating facilities, and shall not have the following behaviors that hinder the normal operation of heating facilities:

1) Installing water discharge valves, exhaust valves or heat exchange devices on indoor heating facilities without authorization;

2) Unauthorized alteration of heating pipelines, installation of pipeline pumps, addition of radiators, or changes in the nature and mode of heat use;

3) Unauthorized discharge of hot water from the heating system;

4) Other acts that obstruct the normal operation of heating facilities.

Kiss! Hello, happy to answer your <>

It is not possible to adjust the heating circulation pump between 1 and 2 under normal circumstances, it should not be too high or too low. Because this kind of equipment needs to be used for a long time, if the gear is adjusted to too high, the motor in it will rotate for a long time, and it is easy to wear and tear, and the entire motor will be burned out in serious cases. If the gear is adjusted too low, it will not have the corresponding effect.

The proportion of circulating water pump in the heating system, both the capacity and the number of equipment are very large, and there are many problems in operation. Therefore, it is very important to correctly select, rationally use and manage to ensure normal heating and improve economic efficiency. The following principles should be specifically considered when making a virtual choice:

1) The selected circulating pump should meet the maximum flow rate and head required in the system, and at the same time, the best working point of the circulating water pump should be as close to the actual working point of the system as possible, and it can be operated in the high-efficiency area for a long time, so as to improve the economy of the long-term operation of the circulating water pump. (2) Strive to choose a circulating pump with simple structure, small size, light weight and relatively high efficiency. (3) Strive to operate safely, reliably, smoothly, with low vibration, low noise and good anti-cavitation performance.

4) Select which pump is suitable for the water wheel with large flow change and little change in head, that is, the pump with a flat g-h characteristic curve. Hope mine can help you <>

Do you have any other questions?

Dear, I'm glad to answer your <>

Answer: If the heating at home is not hot, it is not possible to add a circulating pump. It will not only cause poor heating effect of your own heating, but also affect other users.

Therefore, it is strictly forbidden for heat users to install circulating pumps on heating facilities, for the following reasons: 1. The installation of circulating pumps will destroy the operation of the thermal system, resulting in an imbalance in the entire heating system of their own home or the unit, and causing the radiators to be not hot in the neighbors' homes.

The circulating pump should be installed on the return pipe of the house.

Principle: The wall-hung boiler has a certain height, the upper water pipe has the advantage of water pressure, and the return water needs to go up to the fireplace, which requires a certain water pressure, so the circulating pump is installed with the return pipe.

Circulating pump: refers to the circulating liquid pump used to transport reaction, absorption, separation, and absorption liquid regeneration in the device. Under stable operating conditions, the flow rate of the pump changes relatively small. In the case of a small and low head, which is only used to overcome the pressure drop of the circulating system, a low head pump can be used.

Circulating pump function: circulating water, for example, the hot water in the plumbing heating pipe is circulated by the circulating pump.

Features: A circulating liquid pump for transporting reaction, absorption, separation, and absorption liquid regeneration in the device. Generally, a single-stage centrifugal pump is used. The flow rate of the circulating pump is medium, and the flow rate of the pump changes relatively little under stable operating conditions.

This is actually pretty much the same, and you can take it.

In fact, the temperature of the inlet water and the temperature of the return water are not much different, and there are also those connected to the inlet pipe and the return pipe.

The working principle of the circulating pump: the water is circulated, the hydraulic oil is circulated in the hydraulic system to filter and cool, and the circulation is repeated, for example, the hot water in the plumbing and heating pipeline is circulated by the circulating pump.

3. The circulating pump will reduce the cavitation allowance of the circulating pump in a high-temperature environment, and the water will be vaporized if the temperature is too high, which will cause the circulating pump to not be able to pump water, and it will also affect the service life of the circulating pump.

Hope it can help you, thank you.

It works well when installed on the return pipe.

It is best to put it into the water pipe.

The return pipe is equipped with a control valve.

I have also experimented for many years, and the effect of installing the outlet is not as good as installing it at the water inlet. Because the water pump is heated when it works (although there is water flowing, the temperature is significantly higher than the inlet water temperature), so the installation of the water inlet plays a double role, one is to increase the flow rate and pressure, and the other is to heat the inlet water temperature, so that the temperature of the radiator is higher. In the past, it has always been believed that the rebate at the installation site is correct, but practice has proved that the installation of the water outlet only heats up the water outlet temperature, and the heating temperature rise is not obvious or even the effect is negligible, wasting electricity in vain.

Yes, the circulating pumps are all three levels of adjustable power.

For example: small, 80 watts, 100 watts, 120 watts, three adjustable mid-sized 100 watts, 120 watts, 150 watts.

If your room is more than 150 square meters, it is recommended to choose 120 watts, 150 watts, and 180 watts.

Around 120 square meters use the second kind.

The first type is used for less than 100 square meters.

It is recommended to install a programmable timer at the same time. Work and stop in time slots on your own. There are two benefits, one is energy saving, and the other is less impact on neighbors. Otherwise, running for a long time will cause the surrounding neighbors to be heated.

When it is out of use in summer, turn on the pump once a month to prevent the pump from locking.

If you have a house of more than 100 square meters, you can install a Grundfos or Wilo 15 6 pump on the return water, and add a thermostat or timing control to the power supply

Shielded silent pipeline circulating booster pump basically does not pay attention to listening, there is no noise, ** are three gears power adjustable.

For less than 100 square meters (4 pipe diameters), 80 watts, 100 watts, 120 watts, 120 square meters or so (6 pipe diameters), 100 watts, 120 watts, 150 watts, 150 square meters, more than 200 square meters (one inch diameter), 120 watts, 150 watts, 180 watts.

Be sure to install a tubing filter at the pump inlet.

The installation of the water pump is to pay attention to the installation direction after water injection, and be sure to exhaust.

At the same time, an adjustable temperature switch can be installed to extend the life of the pump and reduce energy consumption (if the water temperature is lower than the set value, the pump will stop running, and unnecessary operation will be stopped).

It doesn't need to be used, it's just two meters higher, and there is water pressure in the heating pipe, which can completely solve this problem.

Personally, I think that a circulating pump is needed, because after the water pipe is raised by two meters, the water pressure will be insufficient due to the atmospheric pressure, so the water circulation cannot be well guaranteed. Therefore, it is necessary to use a circulating pump.

I think it's needed, because the two-meter height adjustment still changes a lot.
