"Smart" circulating pump in the heating system: Features and Advantages

The past winter heating period of strong frosts, sudden thaws and frequent transitions through 0 could identify all the pros and cons of the heating system of a country house. As a result, depending on the efficiency of the equipment, or homeowners spend on heating Cottage planned funds or overpaid and think, how to reduce costs in the next heating season.

There are several ways to upgrade the heating system and thus reduce operating costs in the long run. One of them - to equip "inzhenerku" circulation pump adjusts flexibly to the constantly changing operating conditions. We understand the issues with the help of an engineer of the manufacturer of circulation pumps.

• What are the features of a modern heating system.
• Why the need for a circulation pump with intelligent control system.
• On what is based the principle of the circulation pumps with electronic control system.
• What economic benefit of using "smart" circulating pump.

Features a modern system of a country house heating

Depending on the region, the heating season in our country, on average lasts 6-7 months. Because energy prices are rising all the time, there is growing interest among the owners of country cottages to the construction of energy-efficient homes, ie buildings, where all the power losses are minimized. Practice shows that the correct approach to the process of the construction of the house (based on teplotehnicheskom calculating) the money spent on its construction, come back as a reduction in the payment of costs energy.

But often in this type of overlooked one important point - the construction of energy-efficient, and therefore cost-effective home requires solving a complex task. In addition to the insulation, installation of ventilation systems with heat recovery, to minimize costs need to improve efficiency of the heating system.

Heating "inzhenerki" country cottage includes the most diverse equipment. This - solid fuel, gas, electric or diesel boilers, underfloor heating system with radiators or wall thermostatic heads, etc. Therefore, the heating system of a country house is equipped with a circulation pumps.

Often set regular (non-adjustable) Circulating pumps in the heating system, all the time working at constant speed, or the speed with level adjustable head coolant 2-3 bands.

Such pumps can be inefficient and outdated structure running engine. This leads to significant overspending of funds. To avoid this, the heating system can be upgraded by installing it in a "smart" circulator.

Advantages of the circulation pump with intelligent control system

Anastasia Listopad (Engineer pumping equipment Wilo company):

Unregulated heating pumps consume large amounts of power, since during the heating period they are working at maximum capacity. While in fact most of the time the heating system is operating in partial load.

For example, when a sudden warming (this frequently occurs in winter), the user lowers the coolant temperature and pressure, as from heaters requires high heat. Also, the heating system is not the maximum efficiency is needed at the beginning and end of the heating season, when it's only set the cool weather and heavy frosts have not yet arrived. When changing the day or night, when leaving the home to work during the day when using thermostatic heads, installed on the radiators, you can lower the temperature in the premises and thus, to save costs heating.

That is, during the heating season from the circulation pump is required the maximum capacity only a limited period of time. Therefore, the pump must be flexible to adapt to the constantly changing conditions of use and personal preferences of people living in the house.

Anastasia Falling Leaves:

old generation pumps allow to manually select one of several constant speed (typically two or three). Often, these pumps can operate at full speed, even if all the radiators are closed. This leads to unnecessarily high energy consumption.

Modern "smart" circulating pumps are equipped with high-efficiency motors with automatic power control. This optimizes the hydraulic parameters of the pump under all operating conditions of the heating system, and especially in partial load conditions, which enables significantly reduce energy costs.

Additional energy savings achieved by activating the automatic mode and the speed reduction Dynamic adapt functions. This function of continuous dynamic adjustment of the operating point of the pump in the partial load area.

Due to the constant adaptation of the operating point of the pump as well as automatic air removal function, the use of electronic pumps avoids noise in the system, which is especially important for residential

The principle of the circulation pumps with electronic control system

As mentioned above, in our climate zone there are significant changes in ambient temperature. Regardless of weather conditions, the user is required to provide continuous comfortable air temperature in the premises.

At low temperatures, as a rule, all radiators are opened, maximum flow of coolant required. At growth temperatures outside of the radiator is covered - the system passes through fewer coolant.

modern "Smart" circulators able to adapt to changing system loads. Electronic control system allows the pump to automatically change the motor speed, depending on the state of the system (number of open radiators). Unlike standard pumps, with manual selection of one of the two or three speeds, integrated inverter "smart" pumps with high precision automatically changes the motor rotation speed that allows you to instantly respond to changing conditions in the system heating. Thus, use of circulating pumps with intelligent control system significantly reduces power consumption.

Anastasia Falling Leaves:

Also, these pumps have a choice of one of several regulation modes, which allows for optimal operation of the pump in a particular system.

Depending on the set control method, the pump electronics support or linearly changes setpoint differential pressure, according to the current state of the system (e.g., number of open radiators) together with the feed varies pump. motor rotation speed is constantly changing, and therefore, automatically, without user intervention, the pump adjusts to the changed operating conditions.

The economic benefit of using the heating system "smart" circulating pump

What is the savings in install the heating system of "smart" energy-saving pump? This is a key question that any interested developer, who intended to buy a circulation pump with electronic control system.

Benefits should be seen as a whole and, most importantly, in the long run. For example, a typical unregulated circulating pump for the heating system consumes an average of 500-800 kWh per year. For comparison: TV - up to 200 kW • h per year, washing machine - 200 kWh per year, electric cooker - 450 kWh per year, as normal circulating pump runs constantly and maximum capacity. But above domestic equipment is included only periodically.

Anastasia Falling Leaves:

The minimum power consumption of modern energy circulation pump 3 is W, and the average annual consumption does not exceed 50 kWh.

Therefore, the "smart" pumps can save up to 90% compared with standard pumps, since they automatically adapt to the changing parameters of the system and are equipped with high-performance, cost-effective electric engines.

Also remember about such important factors as autonomy at home. Rural residents are well aware that sometimes there are power outages, failure of substations and power lines breaks. To the heating system continues to operate, it is equipped with an uninterruptible power supply. UPS, feeding the boiler circulating pumps and allow to operate the heating system until the restoration of central power.

Placing an energy efficient circulation pump with a small power consumption, greatly increases the user during operation of the UPS from the heating system. Or can reduce the cost of its installation, because need inverter unit battery of smaller capacity.
