Water pump for heating: how to increase the efficiency of the system

Water pump for heating - is a device that is used to increase the efficiency of self-contained private houses heating systems, as well as cottages. Such a device acts on the movement of coolant, which occurs continuously. Today there are many varieties of such circulators. To select a suitable device should be read with its operating principle and technical characteristics.

The principle of operation and specifications of circulating pumps for heating systems

this type of pump is a device which is located inside the engine and the working shaft. Its main function is in pumping the hydraulic fluid. The popularity of such devices in the autonomous heating designs due to the fact that they allow you to more efficiently heat the building.

The principle of operation of the circulation pump is quite simple. When the rotor begins its startup affect the impeller (rotate it). Thanks to this input creates a negative pressure, and the outlet, on the contrary, increased. The speed of movement of the working fluid communications increases, thus reducing the financial costs for heating private houses.

In many models it is possible to carry out the speed mode is an option that is chosen individually, depending on the specifications of the autonomous heating communications. As well as circulating pumps for water equipped with a specific label, which specifies the main characteristics of the device.

Advantages of circulating pumps for heating systems

Previously, installation of heating communications in private homes does not include the installation of pumping equipment. The working environment in such systems is moved by gravity through pipes. Today some cheap boilers for solid fuels, are performed without integrated pumps. This is explained quite simply - a company that produces boilers, does not know the parameters of the heating circuit. For such structures is recommended the purchase of the circulating pump unit.

There are several advantages of pump installed in a private home heating system. For example, reduced load on the heating boiler through the equalization temperature in the incoming and outgoing pipe. Another advantage of the circulation pump is that it provides uniform heating of rooms due to the same fluid temperature at any point of the heating ring.

Also, when mounting such a device there is a possibility of operational regulation of the coolant temperature in the heating tubes. And it should be said that when you run an autonomous heating heating boiler design is much faster if the system is integrated in a pump.

The principle of operation of the circulation pump eliminates the need for pipe arrangement under a certain bias to the boiler. And also it is possible to use less fat pipe communications. This not only saves space but also reduces the cost of heating design as a whole.

dependence on electric network - only one can be isolated from drawbacks of this device. If frequent interruptions occur in the network, then the use of the device will be difficult. However, this problem can be overcome quite simply by setting bespereboynik (UPS).

Variety of circulation pumps for heating private houses

To date, all the models of such devices are classified on the basis of the action of two types:

• "Dry";
• "Wet".

Many people are interested in the question, how to choose the circulating pump to be installed in a private home. Devices "dry" type are more bulky dimensions and include the engine compartment, extended to the side. Such models are not often installed in homes. This is due to the fact that when working they make a lot of noise. However, such devices have a high efficiency - 80%.

Note!Devices "dry" type require careful maintenance. This is due to the fact that their sealing elements very quickly wear out and must be replaced in time.

Typically, such devices are mounted in a separate building because of their noisiness. Operational scope pumps "dry" type - heating units that differ high power. And they can be used in stand-alone heating communications requiring maximum performance. In private homes, such devices are installed practically.

Features of "wet" pumps for heating in a private house

Devices of "wet" type are much more compact and versatile. Their assembly is performed by tapping into a pipeline structure, in contrast to "dry" devices that require a console unit. And they do not require a further cooling system, as excess heat is given to a working environment that passes through them.

Performance circulators "wet" type below. This is due to the fact that the rotor operates in the liquid working medium which has a certain resistance. Therefore, the efficiency of "wet" pumps varies from 50 to 60%. Nevertheless, the use of such equipment is considered to be the most optimal in terms of autonomous heating systems.

Characteristics of circulating pumps of this type allow them to be mounted even in living rooms. During operation, they practically do not emit noise. And it is worth saying that the poor performance of these devices is fully paid off, because their work requires much less electrical energy.

Power small models used in private homes, is approximately 25-50 watts, which is comparable to the energy consumed by conventional light bulbs. And it is worth saying that the circulating pumps for heating (12 V) are ideal for small private homes.

Industrial term "wet" the circulation pump may be several decades (in normal use). These devices differ unpretentious care, and do not require preventive maintenance.

Thus, for home use, these products fit perfectly. Another advantage of these pumps is their design. It includes individual modules (nodes), which, if necessary, easily replaced.

How to choose a circulating pump for heating Tips

Many are interested in the question of how to choose the circulating pump for heating. For the selection of items for a specific heating communication is necessary to pay attention to several factors. Most such devices have a visual similarity among themselves, however, and they may differ according to its specifications.

For use in private to choose devices that operate on a standard network with a voltage of 220 V. A very important parameter is the power of the device. It depends on two main factors: the model and the mode in which the pump operates. Appliances have a power rating that is not more than 50-70 watts.

experts also recommend to pay attention to the temperature of the coolant. All household circulators have limitations on this indicator may be used in heating systems with temperatures up to 110 ° C.

How to choose a circulating pump for heating, focusing on the geometric parameters? From the standpoint of geometric parameters, plays an important role overall length of the device, as well as display section of the threaded portion of the device. Most pumps are installed on the pipe by means of union nuts, which are also called American women. Typically, such elements are included in the packaging device. Standard section indicators that apply to home heating circuits - 25 and 32 mm. A mounting device length may be 13 or 18 cm.

Among other things, pay attention to the label, which is applied to the pump housing. There is often specified protection class electrical appliance, as well as indicator of the maximum output pressure. The first parameter is the standard for most of today's models and has the designation IP44. The maximum output pressure in most cases, is 10 bar.

If necessary, you can always consult with a specialist who will help you choose the right device for your heating design. A can also be set, to your question, one of the specialized forums on the Internet.

How to choose a circulating pump for heating, depending on the performance

Another important parameter to be considered when selecting the equipment, is its performance. This figure indicates the number of the working medium, which device is able to pump for a certain unit time (m³ / h). Also, it is worth considering the amount of pressure that is able to create a pump, calculated in meters.

In most cases, the main technical characteristics of such devices are specified in their name. For example, if the parse "Grundfos UPS 32-80» name appliance, the first two digits represent the diameter of the pipes (32 mm), and the second - the magnitude of pressure which is equal to 8 m.

Note!be sure to hold it for a specific calculation of the heating system when choosing the appropriate device. This will allow to get the most suitable circulator unit.

By selection of the circulating pump must be approached maximally correctly for the heating system. Therefore it is necessary to take into account even such things as the condition of the premises and features of the climate of the region where you live. If your home has a good thermal insulation, then it is sufficient to manage the device with a small capacity (and vice versa).

You also need to take into account the dependence of the pump power from the climate of the region. In this case, traced the following pattern: the colder climate of the area in which the building is residential, the more powerful the circulation device is needed. If necessary, the question of how to choose the circulating pump for heating, you can help to answer the specialists in specialized stores.

Features of the calculation of the circulation pump for heating systems

power calculation - a very important operation, which is necessary when selecting the water pump. When buying too powerful device in water communication will make a noise, and if you take the device with a small performance index, then the house will warm uniformly.

To buy a circulation pump for heating systems (particular), in fact, necessary to calculate two parameters: the engine performance and the magnitude of the supply pressure.

Operating power-circulating pump is derived from the total heat output of the heating structure. This implies that the device is required to pump the volume of coolant in an amount such that it was enough to heat all the radiators in residential construction. Calculation of operating power devices - individual procedure, as each house requires a different amount of resources.

There are two popular methods of determining the operating power of the water pump:

• using an online calculator;
• by formulas.

In the first case it is necessary to find an appropriate online calculator on the Internet using the search bar of your browser. The second method allows you to perform a calculation of power more accurately. Consider the formula by which we can determine this figure:

3600U X = (A x B)Where:

U - heat costs required to heat a certain area of ​​the house;
A - indicator of water conduction, which is 4.187 kJ / kg;
B - temperature difference at the supply and return line. In most cases, this rate is 10-20 ° C.

Helpful information!For installation in the heating circuit in private homes, has an area of ​​100 m² sufficiently appliance with a working capacity of 10 kW. Thus, for a 10 m² it requires at least 1 kW.

Characteristics of the circulation pump for heating said at its housing, may also assist in determining the working power.

Water pump for heating: installation

On the correct installation of the water pump is dependent on how well it will cope with their functions, as well as the efficiency of the heating of communication in general. There are some basic guidelines that you should follow when carrying out installation work.

How to install a circulating pump for heating? Installing such equipment on the heating circuit only after overlapping its water. It is important to remember that the rotor axis of the device must be placed horizontally. Setting this element in the vertical plane is strictly forbidden. Also, before the circulation device is recommended to install a filter which is necessary in order to catch solid foreign elements of the working environment.

If you plan to install circulating pump underfloor heating system, it is then necessary to place it in the correct contour point. The most appropriate option - mounting on the flow pipe. This is due to the fact that in it the risk of air pockets is minimized.

Do not forget to seal the joints, which is produced through a special FUM tape. After the installation of the equipment necessary to check its performance. For this test run is performed, however, before that you need to take care of the removal of the air system.

Knowing how to properly install a pump for heating, you can save significantly, since such work is not cheap at professionals. But if you do not have confidence in their abilities, it is better to use the services of the master.

The uninterruptible power supply for the heating pump

UPS - it is an emergency power unit, which is installed in the case, if there are problems with the power outage. power outages can cause damage to the heating Communications, related not only to stop heating, but also the failure of its individual components.

Note!To date, there is a huge selection of UPS for circulating heating pumps. They differ in their characteristics, so when you select must be checked bespereboynik compatibility with pumping equipment.

UPS principle of action is simple enough: during the heating equipment from the electrical device stores energy in the event of a fault gives it back. UPS - is a fully automated device, so it eliminates human intervention.

Buy UPS for heating pump can be in the profile store or execute the order through the Internet. Bespereboynik cost ranges from 2000 to 30 000 rubles.
