How to choose a circulation pump for Wilo heating: instructions, reviews, characteristics. Wilo circulation pumps for heating systems - a guarantee of efficient operation Wilo pump operating instructions

For real efficient heating impossible without forced circulation. To do this, it is necessary to install pumps whose design is designed specifically for such operating conditions. And often it is a Wilo heating circulation pump: instructions, reviews, characteristics about which will help you choose the right one optimal model.

About Wilo

Why Wilo? Firstly, this company is the founder of all modern circulation pumps. Back in 1928, she developed the first system for forced movement of liquid in pipes. It was this company that made a serial pump for water heating Wilo with electronically controlled(1988). And despite the rather tough competition, Wilo still remains the flagship in its industry.

A feature of the company's products is A complex approach to solve specific problems - heating, air conditioning or refrigeration. Therefore, the characteristics of Wilo heating pumps meet the most stringent requirements, namely:

Wide range performance characteristics – maximum pressure(up to 16 bar) and temperature (from -10°C to +110°C) of the coolant;
The centrifugal wheel ensures radial movement of water, which significantly reduces hydraulic resistance;
A special feature of the Wilo heating pump design is its “wet” stator. This engineering solution excludes use in construction air cooling engine (this is done by the water itself through the stator). The bearing is lubricated in the same way;
The choice of control system is three-stage, with an extended switching interface or with automatic power control.

But not only these indicators are decisive for the consumer. All circulation pumps for Wilo heating systems are distinguished by competitive prices and quality.

The pump in the heating system is designed to increase the speed of coolant movement. But you need to remember that exceeding this parameter can lead to a loss of heat transfer from the radiators, since their surface simply will not have time to heat up.

How to choose the optimal pump model for autonomous system heating? First of all, you need to calculate its power. Each Wilo heating circulation pump instruction is characterized by such important indicators as pressure (m) and flow rate (m³/hour). Approximate calculation in in this case incorrect. To do this, you should take into account all the features of the system - the height of the house, the volume of coolant, the length of the main line, the thermal operating conditions, etc. The best option Wilo water heating pump calculation – online calculator or a special program.

Only after this stage can you begin to choose a certain model. Reviews of Wilo heating circulation pumps will help you form an objective opinion about the features of its operation. But you need to take into account that the quality of the device largely depends on correct installation and compliance of its parameters with the characteristics of the system.

Some reviews of Wilo pumps say they are ineffective during power outages. To do this, you need to provide sources of emergency power supply - batteries or a diesel generator. Fortunately, the pump’s electricity consumption is minimal.

Circulation pumps Wilo-Star-RS

The main characteristics of Wilo heating pumps of this class are simplicity of design and affordable cost. Its design is a zigzag pipe, in the middle of which there is a circulation impeller.

Models of this class have 3 gradations of rotor speed, necessary for uniform load distribution. Each circulation pump for Wilo heating systems has the following designation:

Wilo-Star-RS N/Q

Where N– size of the nominal internal diameter (from 15 to 30 mm), Q– pressure value (from 2 to 8 m).

In addition to these characteristics, you need to know the connection parameters to the pipeline and to the electrical network. The Wilo Star-RS heating pump device has a 4-position terminal box and an external threaded connection with dimensions of ½”, 1” and 1½”. Design features are also expressed in the following:

Possibility of installation in any position with a horizontal shaft;
IP44 protection;
Electrical network – 220V.

If, after first reading the instructions for the Wilo heating circulation pump, it becomes clear that this power will not be enough, you can purchase a paired Wilo-Star-RSD model.

Its maximum flow rate can be 7 m³/hour with a design head of 5 m. In this case, it is necessary to take into account the synchronous operation of the engines at the same shaft speed. Otherwise, not only will the efficiency of the device be reduced, but there will also be a risk of its failure. In some negative reviews Regarding Wilo heating circulation pumps, there is no mention of improper operation of a specific model. Therefore, their subjectivity should be taken into account.

The average cost of Star-RS depends on its parameters and can range from 2200 to 4500 rubles.

The price of a paired model ranges from 6300 to 6800 rubles.

The pump must be installed in front of the return pipe inlet of the boiler, but in front of the expansion tank.

Circulation pumps Wilo-Stratos

To create automatic control of water heating parameters, it is recommended to purchase Wilo Stratos series pumps. Their mechanical part is completely identical to Star-RS. The difference lies in the electronic control unit.

An LCD display is provided to visualize the current characteristics of Wilo pumps for a specific heating mode. It displays the rotation speed of the impeller. The switching part of the device includes the most common modules - CAN, LON, Modbus, etc. With their help, the Wilo pump device is connected to the heating elements - the boiler and the programmer.

It is noteworthy that the number of models in the Wilo-Stratos series is significantly greater than that of the Star-RS. They have the following ranges of main characteristics:

Maximum flow rate – from 5 to 62 m³/hour;
Pressure value – from 4 to 17 m;
Nominal pressure – from 10 to 16 bar.

Connection can be made using either flange units or threaded connections. The size of the latter varies from 1’’ to DIN-100.

Such a variety of models of Wilo circulation pumps for heating explains the wide range of their prices - from 11,700 to 67,000 rubles.

During installation, you should carefully read the instructions for the specific Wilo heating circulation pump. It will definitely indicate that, regardless of the chosen position, the shaft must be strictly horizontal. This is prerequisite normal operation.

Is it possible to repair the pump yourself if it breaks? The video shows an example of restoring its functionality:

Heating systems that use natural circulation of coolant are slowly becoming a thing of the past. This is due to their low productivity, narrow focus and lack of high pressure in the system, which is important for houses with a large area.

Gradually, natural circulation in heating systems is being replaced by forced circulation, where one of the main units is a circulation pump.

Circulation pumps from WILO: design features and main characteristics

Currently, the domestic market is extremely rich in all kinds of circulation pumps for installation in the heating system.

It should be noted that among them there are both really high-quality, well-designed models and frank Chinese fakes who are not able to work for more than one season.

Naturally, if a heating system is chosen, as they say, “for centuries,” then all the units installed in it must be of high quality, reliable and efficient.

Circulation pumps for Wilo heating systems, produced by the famous German concern, are in great demand among domestic consumers.

As you know, the Vilo heating circulation pump is the “heart” of a modern heating system and the manufacturing company understands this.

Tip: Vilo pumps are available in a wide range, so before purchasing a specific model, it would be a good idea to consult with specialists. Only professionals will give specific advice and help you choose the best unit for each specific case.

Vilo circulation pumps – performance and quality

IN modern systems heating circulation pumps for heating Wilo perform an extremely important task - they ensure the rapid movement of coolant in the network. As a result (and the instructions for Vilo pumps talk about this), heat transfer improves almost significantly, and the efficiency of the system increases.

Also, if the circuit contains a Wilo circulation pump for heating, you can significantly save on pipes, because the lines (due to forced pressure injection) have a significantly smaller diameter than if natural circulation were used.

As for the equipment itself, Vilo pumps are practically silent, reliable and practical, have compact dimensions and do not require any special maintenance.

Any circulation pump from Wilo SE is a modern and efficient unit that works for a long time and trouble-free. It should be noted that installing it yourself will not turn into some kind of complex and time-consuming operation. And the price for such equipment is much lower than for analogues presented on the domestic market.

A wide range of Wilo pumps – the ability to make your heating system efficient

The domestic market simply offers huge selection modern, reliable and high-quality pumps of this German company. In many photos and videos posted on the Internet, you can easily see the main range of equipment that the Wilo group really produces in abundance.

Among the most popular models of Vilo circulation pumps are:

Advantages of using Vilo pumps in heating systems

Modern circulation pumps for Wilo heating systems are an excellent choice for any property, no matter how small country cottage or industrial enterprise.

Using Vilo pumps for systems with forced circulation coolant allows you to get a lot of advantages:

Increasing the efficiency of coolant flow through pipelines, better heat transfer even in the farthest corners of the heating system;
Reduced fuel consumption by boilers and, as a result, significant financial savings. Particularly relevant for large boiler houses on manufacturing enterprises and other objects;
Extending the trouble-free operation of the heating system.Circulation pumps capable of creating quite high pressure in the pipeline, which eliminates the deposition of salts from the coolant . In turn, blockages and narrowing of pipe diameters are eliminated.

Conclusion

As you can see from the above material, such pumps for heating systems (although their installation is also possible in hot water supply pipelines) can improve efficiency and productivity, reduce costs, and also eliminate breakdowns.

Pumps from the famous German brand are surprisingly well integrated into existing and functioning heating systems (due to their low weight and dimensions). They ensure fast coolant flow and circulation throughout all radiators.

However, their choice must be approached with all responsibility, taking into account the area of the heated premises, as well as friction losses in the pipes.

Choosing WILO circulation pumps is a great opportunity to become an owner effective system heating Such equipment fully meets all quality standards and is made only from the best materials and on innovative technologies.

- look here.

Heating systems in which coolant circulates in a natural way according to the law of gravity, are found less and less often, and only where small area heated using a single-circuit boiler.

Forced circulation equipment

Ensure quality travel hot water Wilo circulation pumps will help with pipes and radiators. They do their job well in big houses with complex branching of heating systems. Do right choice a modern and compact device that will show effective operation will be helped by a review of Vilo models and instructions from the manufacturer.

All German-made units are distinguished by their reliability, ease of installation and the ability to reduce the diameter of the pipes, which allows reducing the cost of heating installation.

For complete heating of private houses, two series of Wilo pumps were specially developed, which differ slightly in technical characteristics.

This range of pumps has a low power and is suitable for use in houses whose area is in the range of 200 - 750 m².

Peculiarities

The main advantage of this series is the wet type rotor. It is continuously immersed in the pumped energy carrier, which prevents the graphite bearings from drying out. Another advantage of Star-RS is that a technical polymer is used to produce the rotor wheel.

This material is resistant to impact high temperatures, characteristic of heating systems, and is not afraid of their sudden changes.

Housing and fasteners

The Vilo circulation pump is connected to the pipeline using a thread, the diameter of which may vary depending on the model. The unit has a cast iron body and a stainless steel shaft.

Comfortable working environment for such a device it is water or a water-glycol composition. Star-RS pumps for forced heating systems are almost silent. They quickly pump coolant and consume little electricity.

Advantages

German equipment of this series has gained great popularity due to the following advantages:

the body is coated with an anti-corrosion cataphoresis compound;
speed is regulated using a three-stage mechanical switch;
durable metal-graphite bearings do not wear out in aggressive temperatures;
low cost.

Operating and installation conditions

Devices for heating systems of the Star-RS series can operate in temperature conditions+10 +110 °C at a pressure of up to 10 bar, and this makes it possible to use them in air conditioning.

When installing Vilo Star-RS, the manufacturer’s instructions must be strictly followed, which states that:

insertion is possible after installation and cleaning of pipes from chips;
the terminal box and motor must be reliably protected from moisture;
The pump axis must be positioned strictly horizontally.

TOP-S series

Models in this series are designed for use in buildings with an area of up to 1400 m². Such pumps with single or three-phase connections guarantee accelerated pumping of hot water through pipes and radiators.

They are made using materials similar to the previous line from the German company Wilo.

Operating and installation conditions

The equipment operates at a temperature of +20 + 130 °C, and for two hours the units can operate uninterruptedly at an increase in maximum temperature of 10 °C. The permissible pressure is 6, 10 or 16 bar (special version). As in the previous case, the speed is regulated by a three-stage switch.

The Vilo TOP-S series is available with increased engine protection and a thermal insulating casing. The versatility of Wilo equipment is due to the double-sided cable connection and the configuration with a 6/10 bar combined flange (for models with an internal diameter of 40 - 65 mm).

Product advantages

Circulation pumps from the German company Wilo successfully compete with similar devices due to the fact that they are made from anti-corrosion materials and can work with various coolants.

They are durable and easy to use, and also consume electricity economically. Another important factor that affects demand is the compact dimensions of the units with their multi-stage protection.

Signs of the original

Given the popularity of Vilo products for heating systems, there is a risk of purchasing a counterfeit. To avoid troubles when purchasing, pay attention to the following signs of the original:

minimum price – 80 USD;
presence of a serial number on the case;
manufacturer's instructions;
two mounting bolts out of four (the fake has 4).

Model overview

In order to have an idea about technical parameters Vilo products, we suggest you familiarize yourself with the main parameters of the devices. The table shows the average price of goods that are represented on the Russian plumbing market.

In Russia, the official representative of the international company Wilo is Wilo Rus LLC. She has many partners in many cities of the country. Each partner is issued a certificate that confirms his right to sell products of this brand. We do not recommend buying anything from non-certified dealers, as you may end up with a fake.

Vilo heating pumps with wet rotor

The technical characteristics presented in the catalog of Vilo pumps with a wet rotor allow them to operate in autonomous heating with a pressure of up to 10 bar. The coolant is pumped through an impeller mounted on a shaft (rotor). The peculiarity of this line is that the rotor must always be immersed in water (coolant), which performs two important functions: lubrication and cooling. This condition imposes certain installation requirements - the rotor must be in a horizontal plane. By following this simple rule, you will not have to think about repairing Vilo pumps (see).

The line is divided into two categories: with automatic power control and with manual power control. A total of 21 models of wet rotor pumps are presented. Their body is made of gray cast iron or bronze, the rotor is steel, the impeller is made of plastic, and the bearings are metal-graphite. The unit can be installed on the circuit using a threaded or flanged connection. The last option is typical for Wilo industrial pumps.

It is still the most popular and economical.

Before that, calculate the required thermal power.

In autonomous heating you need through mixing unit, which regulates the temperature of the coolant.

A coarse filter (dirt filter) must be installed in front of the pump. It is needed to prevent solid particles from falling on the impeller blades and breaking them. The coolant always contains deposited salts or metals (scale), and the quality of water in central networks is generally terrible.

The pump is attached to the circuit with American connectors - a detachable connection, which in turn are installed on ball valves. This will allow you to cut off the pump from the circuit at any time and remove it for repair or maintenance without draining the water from the entire system . without the provided recharge from the water supply - for a long time.

The circulation pump is an integral element of any heating system with forced circulation. The stability of coolant circulation through the pipeline depends on this small device.

Pumps from the manufacturer WILO can rightfully be considered one of the best.

Why do you need a circulation pump at all?

In some cases, you can completely do without this element, when we're talking about about systems with natural circulation. In this case, the coolant moves through the pipes due to the pressure difference that occurs when water is heated in the boiler. The coolant expands when heated, part of it is simply squeezed up the supply pipe, rising to the very high point water enters the radiators and, gradually cooling, moves back to the boiler ().

The only advantage of such an organization of home heating is absolute independence from electricity. This is important, for example, when heating country house or cottages in a hard-to-reach area. In addition, the absence of moving elements in the system extends its service life

But it is better to install a circulation pump for Vilo heating at the entrance to the boiler.

As for the advantages, installing such a device makes it possible to:

ensure stable circulation of coolant through the pipes. Modern models are able to reduce the speed themselves, making the heating of the house less intense. This quality is especially useful in terms of financial savings;
the pressure will not depend on the diameter of the pipe (in systems with natural circulation it is better not to use small diameters);
installing a pump does not reduce the durability of the system as a whole, modern models can work for 20-30 years.

The only disadvantages that can be noted are the small costs of electricity and noise. But the boiler is usually located in a separate room, and the price of electricity is not so high as to refuse the pump.

Classification of circulation pumps

As for the principle of operation, all devices of this kind can be divided into 2 types:

with a “wet” rotor;
with a “dry” rotor.

For heating a relatively small house, options with a “wet” rotor are preferable. They received this name due to the fact that the rotor (the part that rotates) is placed directly in the pumped coolant.

Wilo heating circulation pumps of this type have the following features:

almost completely silent;

Note! IN small houses sometimes it is not possible to move the boiler away from living quarters, so noiselessness is an important advantage.

no lubrication is needed - the rotor is in water, so the coolant itself plays its role;
for greater reliability, the rotor chambers and stator are separated by a durable stainless steel sleeve;
The only and rather significant drawback can be considered low efficiency - about 50%.

Note! The “wet” pump must be installed so that its shaft is horizontal.

To operate a powerful system, it is better to use a Wilo “dry” circulation pump for heating. Unlike its “wet” counterpart, its rotor is not in contact with the coolant at all, and a high degree of tightness can be achieved due to the pumped liquid itself.

During operation, a thin film of liquid permanently seals the microscopic gaps between the rotating surfaces. Over time, the O-rings wear down a little, but the problem is solved by the fact that they are spring-loaded and simply shift by the amount of wear, the main thing is that the grinding occurs evenly.

The main advantage of “dry” devices is an efficiency of more than 80%. And the disadvantages can be written down high level noise, which is why such pumps are used mainly in powerful systems.
