The German company WILO was founded back in 1872 in the small town of Dortmund. The beginning of the story was laid by the German engineer Wilhelm Louis Opländer. It was he who patented the first heating pump. The name itself is nothing more than an abbreviation of the full name of the founder. For more than 140 years, the company's activity has been closely connected with the development of technological progress in the field of pump construction. Today, WILO SE rightfully occupies the first position among the world's leading brands. The company boasts more than sixty manufacturing plants, and the number of employees is about 7 thousand worldwide.

In the domestic market, Wilo is known for its Russian division WILO RUS, which has been successfully operating for over 20 years. Today we will talk about the household series of circulation pumps vilo. Let's make an overview of the model range, consider the device and technical characteristics wilo. We will analyze the principle of operation, touch on the advantages, talk about the disadvantages. We read user reviews and draw our own conclusions.

The task of the Wilo pump

The main task that the circulation pump must perform is to create pressure in the heating system. Until now, where it is not possible to use this kind of equipment, a gravitational scheme is used. This version of the heating system implies a more bulky design. The pipes used in the gravity system have a larger diameter, they need a slope, this disgrace looks extremely unaesthetic, the coolant moves slowly by gravity inside the heating system, and the efficiency leaves much to be desired.

The use of a circulation pump ensures the correct uniform flow of the coolant in the heating system circuit. The Vilo circulation pump provides pressure, allowing you to make an efficient heating project with a smaller pipe diameter, using radiators. Together with a “smart boiler” and modern battery-powered thermal heads, a frequency-controlled pump will help balance the heating system and get comfortable conditions in any room of your home.

Domestic circulation pump WILO Device

The modern household Wilo Circular pump is a single design. The hydraulic volute is made of high quality cast iron alloy. The pump body, in which the asynchronous motor fits, is made of die-cast finned aluminium. The rotor is made in the form of a cartridge, mounted on mechanical sliding bearings made of metal graphite, made of stainless steel in a sealed case, it is not repairable and in case of breakage, it changes entirely.

The polypropylene impeller is mounted on a stainless steel shaft. The stator is securely separated from the rotor. This design is called a “wet rotor” and differs from a conventional pump in the absence of air cooling. The motor is cooled by the pumped liquid. The two parts of the pump are fastened together with just two bolts through a gasket. The vilo pump includes threaded connections and two gaskets. The temperature regime of the pumped coolant can reach + 110 degrees Celsius.

It remains to be added that the Wilo pump has a three-speed control, with switching on the terminal box. The Wilo pump is equipped with an internal motor protection, so there is no need to install additional overload protection. The start capacitor is placed inside the terminal box.

The built-in thermostat is included in the package of devices under electronic control. The maximum pressure provided by the pump reaches 7.5 Atm., and the flow rate reaches 12 m3/hour. Such parameters allow you to equip a heating system with room sizes from 150 to 2300 square meters.

Heating pump Wilo Star

The Wilo Star RS series is a glandless circulation pump. He firmly established himself in heating projects, his element is water supply and air conditioning. The device is in the lowest price group of heating pumps, it combines the optimal affordable cost and high quality. The Wilo Star RS pump perfectly copes with the task of arranging the heating system of country houses and cottages up to 760 m2 in size, having a weight of only 4.9 kg.

The line includes the following models:

Wilo Star RS - is manufactured in 17 modifications, with the name from Wilo-Star-RS 15/4 to STAR-RS 25/6-RG. Despite the numerous manufacturing options, there is a “German order” in the names of the models and their decoding is quite simple, let's figure it out:

Pump Wilo-Star-RS 25/4

• Wilo Star- circulation pump with translation into Russian fork-star;
• RS- the pump has a threaded connection;
• 25 – internal, nominal diameter Rp, meaning that this model is installed on a pipe of 25 millimeters; 32 – pump model per pipe, respectively 32 mm;
• 4 – Q = 0 m3/h;
• Execution RG with a bronze body and a small installation length of 130 mm;
• Execution RSL means air valve connection.

4035758	STAR-RS 25/4-RG	176
4035761	STAR-RS 25/6-RG	191

Wilo-Star-RS

The Wilo-Star-RS is manually controlled and generates pressures up to 10 bar. Throughput reaches 6 m3/hour. Since the manufacturer took care of completing the pump with nuts, the buyer does not need to puzzle over which threaded connections to purchase during installation. The pump has a standard installation length of 180 mm, with the exception of five models that can have 130 mm - this length is usually used when space is limited - for example inside a gas boiler.

Wilo Star modifications

There is a modification of Wilo Star RSD - this is a variant of a double pump. From the point of view of engineers, such a “two” can not only increase the pressure in the heating system, but also extend the service life, provided that the pumps are switched on alternately. In addition, it is possible to provide for the connection of a double pump to two different circuits.

A special switch is included with this modification, which regulates the operation of two electric motors. But according to our experience and numerous reviews of installation organizations, we can say that the dual model has not found wide distribution. Firstly, it is bulky, secondly, it is expensive, thirdly, it requires control, and it is easier to put two independent single pumps on a pipe with a diameter of 32 mm.

Technical data Wilo-Star-RS

Pump Wilo Top

The next model we will look at is called Wilo Top. The model is a logical continuation of the line of pumps with the purpose of arranging heating and air conditioning systems; it differs from the previous model in increased technical characteristics.

The Wilo Top pump is already able to circulate the coolant in medium and large industrial plants. The pump is widely used in various heating points, multi-apartment multi-storey buildings, schools and other institutions. Performance Wilo Top provides stable performance in heating systems up to 1400 m2. Let's look at the "German order" and the decoding of the Wilo Top pump:

Wilo top modifications

The manufacturer of the concern manufactures at its enterprises about 50 modifications of the Wilo TOP pump. The main differences lie in the flange mounting size and technical performance figures. In addition to the standard version S, the manufacturer Wilo produces Wilo TOP-Z - drinking water circulation systems, the hydraulic part of the pump is made of bronze alloy. The pump has won a strong place in industrial facilities such as schools, kindergartens, and other buildings. Wilo TOP-Z- is intended to be used exclusively for pumping clean drinking water.

Wilo-Stratos pump

An improved model of the Wilo Stratos. Smooth power adjustment. A feature of the pump is the release function. The device module is equipped with electronic control. Created and developed for large heating systems with the ability to connect to an automated control system. It is completed with connection to coppers, with power from 25 kW.

The main advantages of Wilo-Stratos are exemplary energy efficiency with the highest - "A" energy class. The pump electronic control module is located next to the terminal box. The declared power of the Wilo Stratos pump in the peak value does not exceed 48 watts, complete with a “smart boiler” when operating in night mode. Connecting the pump to the thermostat automatically allows you to select the optimal speed, performance, depending on current needs.

Construction of the Wilo Stratos

The basis of the foundation of the Wilo Stratos design is synchronous motor. The rotor is made on permanent magnets. Unlike the stainless steel cartridge used in previous models, the Stratos uses a unique carbon-based composite material as the spacer.

Additionally, there are models made of bronze alloy, in addition, there are options with an increase in pressure up to 16 bar. Providing high reliability, low noise performance. Wilo-Stratos becomes the ideal solution for the operation of large project systems.

Pump Wilo Yonos

The Wilo Yonos pump consists of a cast iron hydraulic block, an electric motor with permanent magnets in the so-called “wet rotor” design. The main advantage of the pump is the use of an electronic unit of the frequency converter of the rotation of the electric motor.

Basic operating modes:

1. Variable pressure (Δp-v):

Within the indicated range, by controlling the rotation of the motor, the differential pressure setpoint is converted linearly. In simple terms, you have a heated room with ten radiators. There are two of them in one of the bedrooms. When there is a fierce winter outside the window, they give you their warmth and no questions arise.

But now spring comes and the sun is increasingly peeking through your window. You get hot and decide to turn off one of the two radiators in your bedroom. It is in this case that the Wilo Yonos pump will take into account the change in the heating system and linearly reduce the speed of the electric motor. Thus, the heating system will be balanced, and in addition, the value of the noise characteristic in thermostatic valves will decrease. Simply put, the system will be quiet and perfectly balanced.

2. Constant pressure (Δp-c):

The mode allows you to maintain a constant set value of the differential pressure H. Wilo engineers advise resorting to this control option, for example, when arranging a “warm floor” system or when operating a pump in old heating systems, where the pipelines are overestimated. The Wilo Yonos pump is ideal for balancing systems where changing network characteristics are unknown.

Wilo Yonos is equipped with an air vent: the duration of the vent function can last up to 10 minutes after activation. Upon completion of the operation of the pump in the air vent mode, one of the two selected control options must be installed.

Operating mode selection

The choice of Wilo Yonos control modes is carried out directly by switching the red turntable. The manufacturer took care of the operation of the pump in automatic mode, a fixed production unit saves energy.

On the front side of the Wilo Yonos control box, the manufacturer displayed an indication of the parameters of power consumption, pressure, set frequency conversion adjustment, and so on.

Pump Wilo-Yonos PICO 25/1-6

• Yonos PICO = High Efficiency Pump
• 25 Threaded connection DN 25 (Rp 1)
• 1-6 1 = minimum head in meters (adjustable up to 0.5 m) 6 = maximum head in meters at Q = 0 m³/h
• Mounting standard length 180 mm.

How to choose a pump for heating a private house

Wilo, as a pump for heating a private house, is used by owners everywhere. The selection of a pump is actually a rather delicate matter and, of course, all the little things must be taken into account. You need to calculate the length of the line, take into account the number of radiators, do not forget about the heat loss and much more. In general, as a rule, the design of the heating system is calculated at the stage of building a house and it is better to entrust such a calculation to a competent specialist. In addition, on the official website of the manufacturer Wilo, you can be helped by an online pump selection program - vilo select.

Wilo pump calculation

However, we can of course give some indicative recommendations. For initial calculations, it is necessary to calculate the heated area, and decide on sufficient power. Roughly enough, “by eye”, the required boiler power is calculated based on 1 kW per 100 square meters.

Having calculated the power of the boiler, it will not be difficult to find out the flow rate of our pump using the formula: Q = N / (t2-t1) , where Q is the flow rate necessary for us to select the pump in m3 / h; N is the power of our selected boiler in watts; t2 - water temperature at the outlet of the boiler; t1 is the water temperature at the boiler inlet.

Next, we need to determine from the hydraulic curve (which is attached to all pumps) the head we need. If you did everything correctly, then with a high degree of confidence we can say that your system will work properly. Do not forget that Vilo pumps are supplied with three speeds, so that on site it will be possible to slightly adjust its operation. With frequency regulation, this will be even easier.

Which pump is better for heating a private house

The modern market offers us to buy a pump for heating a private house at a variety of prices, in the most unusual color, with the best characteristics, well, just in a huge assortment. We will remain conservative in this matter and traditionally arrange products in the order:, Wilo,. All three manufacturers offer excellent quality, and the range and characteristics allow you to accurately select equipment for any designed heating system. Which one is better ?, let's leave this debate for those who like to endlessly find out which is better: samsung or iphone, mercedes or bmw, or finally blondes or brunettes ...

Reading 5 min.

The manufacturing company produces several series of circulation pumps: S, RL, Z and SD. Each series is characterized by its individual features, the description of which we will consider below.

Wilo TOP - description of the model range
