UPS for the circulation pump of heating – we understand the nuances of choice

An efficient heating system is crucial to maintaining a comfortable and warm home. Comfort is guaranteed all year long with a dependable heating system, regardless of the season—from a chilly winter’s evening to a crisp autumn morning. The circulation pump, which transfers hot water or steam from the boiler to the radiators or underfloor heating, is an essential part of this system. Power outages, however, have the potential to cause discomfort and damage as they interfere with these pumps’ ability to function. In this situation, Uninterruptible Power Supplies (UPS) provide a way to continue operating the circulation pump even in the event of a power outage.

To guarantee continuous heating, particularly in extreme situations like freezing temperatures or stormy weather, it is essential to comprehend the subtleties of selecting the appropriate UPS for your circulation pump. With so many options on the market that cater to different needs and preferences, understanding the key factors involved is essential to making an informed decision.

The capacity or power rating of a UPS is one of the most important factors to take into account when choosing one for your circulation pump. Circulation pumps have different power requirements based on the size of the heating system and the pump’s efficiency. Selecting a UPS that can manage the pump’s starting and running power is crucial for ensuring smooth operation without taxing the system’s capacity.

The kind of UPS that best meets your needs is an additional important factor to take into account. Different configurations of UPS systems are available, such as standby, line-interactive, online, or double-conversion UPS. Different degrees of efficiency and protection are provided by each kind. Knowing the distinctions between these kinds will enable you to select the best option for your heating system and circulation pump.

When choosing a UPS for your circulation pump, additional considerations like battery backup duration, surge protection capabilities, and ease of installation and maintenance should be made. In addition to supplying backup power during blackouts, a dependable UPS should protect the pump from voltage swings and other electrical disruptions that might harm its internal parts.

Select UPS for a circulation pump

We have included a few required parameters that should pique interest first for individuals who wish to safeguard themselves against an unplanned blackout.

Outgoing current parameters

A clean or correct sinusoid of the output signal is one of the distinguishing characteristics of a proper UPS, as was previously mentioned. Sine-wave deviations are not acceptable. Such devices with questionable qualities are completely inappropriate for the efficient operation of a gas and solid-fuel boiler with circulation pumps.

Check the product’s passport and find out what kind of sinusoid this UPS is before making a purchase.

Starting power

It will be preferable for the UPS to operate dependably if its capacities are fully utilized to meet the demands of all connected equipment. With this option, our primary concern is having sufficient power to run the boiler’s circulation pump. Lousse, in the event that the UPS cuts the power five times or more. Even better if it is seven times higher than the estimated amount.

Its technical passport will tell you how powerful the boiler room’s electric pump is.

What is an uninterrupted fence?

A device that supplies a steady stream of electric energy is a source of continuous power for the circulation pump. The device starts operating on one or more batteries when the network voltage drops.

The continuous fence is made up of the following parts:

1. Stabilizer for the boiler. Allows you to prevent equipment breakdown for voltage drops.
2. Battery. Accumulates electric energy, giving it out if you turn off the network.
3. Converter. Turns a direct current 12 V into a variable with a voltage of 220 volts.
4. Filter. In the presence of a pulsed converter, it blocks interference.
5. The charge control indicator. Allows you to prevent a critical discharge or reloading of the device.

IBP selection criteria for a circulation pump

Stone and power

The great majority of pumps used in home autonomous heating systems are single-phase, low-power devices that range in power from several tens to several hundred watts. Therefore, single-phase UPSs are appropriate for the matching power to power the pump engine.

Nevertheless, the pump electric motor’s short-term but relatively high starting currents must be considered when selecting a "uninterrupted fence" because they may be three to five times higher than the motor’s nominal consumption power. Considering how efficiently contemporary circulation pumps use energy, a 500–1000 wa UPS will typically be more than sufficient.

Autonomous mode

In the operating manuals on the UPS, manufacturers indicate the value of this characteristic at full load. It is obvious that the actual duration of autonomous operation depends on the consumed power of the pump engine and the capacity of the batteries used.

Generally speaking, adding more external batteries to a modern UPS with built-in batteries increases the container’s capacity and, thus, its autonomous time.

It will be better to choose models that don’t offer regular batteries at all in order to choose the necessary battery capacity. Because these UPSs have stronger chargers, they can operate with larger external batteries, which will extend the time that the "uninterrupted" can operate independently.

Output signal

A sinusoidal voltage or one that is as near to the sinusoid curve as possible is ideal for feeding any load. But frequently, the UPS’s inverter operates in autonomous mode at the output, forming a periodic rectangular signal in each semi-period of the sinus graph rather than the accurate approximated (stepped) sinusoid or even meandering. This signal form, which exhibits a significant distortion in the sinusoidality of the curve, is particularly detrimental to power transformers and alternating power supplies.

Due to the occurrence of additional losses and vortex currents, the operation of the circulation pump on the network with a modified sinusoid signal type causes an unacceptable heating of the stator and rotor magnetic circuit. This lowers the pump engine’s service life, damages the insulation, and increases the likelihood of an early failure.

For this reason, it is crucial to consider the output signal form specified in the manufacturer’s specifications when selecting a UPS for a circulation pump. This has to be the ideal sinusoid in order to power the sensitive electrical signal to the signal’s shape.

Type of UPS

Priority technical considerations for selecting a "uninterrupted" power source for a circulation pump include the output signal’s shape and its speed at transitioning to an autonomous mode of operation.

The devices that possess these qualities in the greatest combination are a double transformation For a variety of reasons, using UPSs (online topologies) and certain linear-interactive models as power pumps is not as ideal.

Offline (or reserve) UPSs are inherently unsuitable as power sources for electric motors (in our case, circulation pumps), as they typically take the form of meander output signals that are only slightly modified with sinusoids at best.

Of the UPS types that were submitted, online topology devices will undoubtedly be the most successful option. Using dual transformation devices has the following benefits over using a linear-interactive UPS, in addition to ideal sinusoids at the output and zero time of the transition to autonomous mode:

• The “clean sinus” signal is ensured at the output both when the load from the network and in the autonomous mode (from the battery);
• constant stabilization of the network voltage and current frequency in combination with continuous filtering of high -frequency interference in the supply network;
• very effective work in networks with large dumps and frequent voltage drops without switching to autonomous mode of operation;
• the ability to connect external batteries;
• the presence of through zero for the correct operation of phase -dependent boilers;
• the possibility of performing a “cold start” – launch of the pump in the absence of voltage in the supply network (in autonomous mode).

The circulation pump in your heating system is essential to effectively maintaining a warm home. Selecting the appropriate Uninterruptible Power Supply (UPS) for your circulation pump guarantees continuous performance even in the event of a power outage. Comprehending the subtleties of choosing the best UPS entails taking into account variables such as power capacity, duration of the battery backup, and compatibility with the specifications of your pump. Purchasing a UPS that meets the requirements of your circulation pump will protect you from heating outages and provide comfort and peace of mind, particularly in inclement weather.

The principle of action of uninterrupted nutrition sources

But like any other pump, the continuous heating pump is made up of an automation unit and a specific container’s battery. In standard mode, the electronic unit uses the integrated charger to charge the IBP battery and stores it in reserve while the pump consumes power from the network. The same automation unit switches the consumer to battery power when the standard voltage is lost.

Nearly every source of continuous nutrition has an electronic converter, or inverter, because the voltage and current of the current required for the consumer typically differ from the voltage at the reserve battery’s terminal. Its job is to convert the battery’s constant voltage to the consumer needed to provide power (a household circulation pump typically requires 230 V or 50 Hz).

The battery is once more ready for charging when the regular energy source is resumed. This is known as the reverse switch. As a result, the UPS is always prepared to go and can supply power to a machine whenever needed. For what duration can the UPS power the same circulation pump? Everything is contingent upon the capacity of the battery. Uninterruptibles come in models that have external batteries that can sustain the load for several days.

A computer UPS is one of the more obvious examples of this type of system. The computer will switch to the battery when the network voltage disappears, allowing the user enough time to finish the task accurately and shut down the device.

Criteria for choosing a backup power source

The selection of reserve power sources intended for use with heating system pumps should take into account various factors:

• Power;
• Battery capacity;
• Permissible autonomous work;
• The possibility of using external batteries;
• Sprout of the input voltage;
• Output voltage accuracy;
• The time of transition to the reserve;
• Output distortion.

A circulation pump’s UPS selection should be based on a number of key factors that affect power.

Determination of the required power of UPS

An essential component of the heating system pump, the electric motor is an inductive reactive load. This should be used to determine how much power the UPS needs for the boiler and pump. The pump’s technical documentation might list the power in watts, such as 90 W (W). Thermal power is typically indicated in watts. The value of the thermal power must be divided into COS ∗, which can also be indicated in the documentation, in order to determine the full power.

As an illustration, the pump’s power (p) is 90W, with an accuracy of 0.6. Formula for calculating full power is as follows:

Therefore, 90/0.6 = 150W should be the UPS’s maximum power for the pump to operate normally. However, this is not the end product. The electric motor’s current consumption increases by roughly three times when it first starts. Reactive power should therefore be multiplied by three.

Consequently, the circulating heating pump’s UPS power will be equivalent to:

The power supply in the aforementioned example has 450 watts of power. In case the documentation does not specify the FI cosine, the thermal power measured in watts must be divided by a coefficient of 0.7.

Battery capacity

The amount of time the heating pump pump will run in the absence of a network is determined by the battery capacity. Built-in batteries typically have a tiny container, which is mostly dictated by the device’s dimensions. Select models that enable the connection of extra external batteries if the backup power source is operating under conditions of frequent and extended power outages.

Input voltage

The acceptable deviations for the 220 volt network voltage standard are ± 10%, or between 198 and 242 volts. This implies that, within these parameters, every gadget utilized by the Russian Federation ought to function properly. Indeed, deviations and stress surges can considerably surpass these values in a variety of locations, particularly in rural areas. It will be very helpful to do multiple, within-day voltage measurements of the network prior to buying a UPS for a heating pump. The acceptable voltage limits at the input, at which the device provides the output voltage close to the face value, are indicated on the passport for a backup source.

Output voltage and its shape

This device will work well to power the heating pump pump if the voltage parameters at the uninterrupted fence’s output are within the allowed 10 percent. Typically, the time it takes to switch from the battery to the control payment is a few tens of microseconds. This is not a crucial parameter for the electric motor.

The output signal shape is a crucial UPS parameter that is required for the heating system pump to operate correctly. Of all the backup source models, the smooth sinusoid needed for the pump electric motor can only supply an on-line UPS or double transformation device. This source outputs the precise voltage and frequency value along with a perfect sinusoid at the output.

Some guidelines to follow when installing a UPS for a heating pump are as follows:

• The temperature in the room must correspond to the values specified in the documentation;
• There should not be vapors of caustic reagents and combustible liquids in the room;
• The grounding circuit should be made in accordance with the rules of operation of electrical installations.

The design of the circulation pump and the requirements for the UPS for power supply

The design of devices dictates the power supply requirements for circulating pumps as well as the need for constant power sources for these pumps.

A centrifugal pump with an electric motor cooled by water is a modern circulation pump. These pumps are also known as "wet rotor" pumps. An electric motor, a rotor, a working wheel with blades, sliding bearings, and adjustment devices are all housed in a metal case on a single shaft. The following figure shows the schematic representation of the circulation pump’s design.

An electric motor is the central component of the circulation pump’s design. Typically, a highly efficient small electric motor is employed.

Proper power supply must be ensured for such engines to operate normally. The electric signal that is sent to the electric motor’s windings needs to appear correctly sinusoidal. Engine operation violations arise when modified sinus power sources are used. Here, the electric motor starts to buzz and warm up. Because of the engine rotor’s uneven rotation, the moving parts of the pump experience additional wear over extended use.

An increase in current strength occurs in the electric motor’s windings when the voltage is continuously lowered, including at the UPS’s output. Consequently, the electric motor experienced severe overheating and eventually failed. Engine noise changes when there is a decrease in voltage, the circulation pump operates under conditions of increased load. Extremely low voltage may cause the pump to stop in an emergency and prevent it from starting at all.

An increase in voltage, including at the UPS’s output, raises the possibility that the pump’s electric motor windings will break. A large voltage increase causes the pump to overheat and eventually fail.

The rotor of the electric motor of the circulation pump rotates at a different speed when the frequency of the current flowing through it is altered, including at the UPS’s pump output. Consequently, there will be an uneven water supply and a shorter pump service life.

Factory models

A suitable fence that won’t break can be purchased from heat engineering and plumbing stores. Online retailers are also using them. Final costs differ based on the manufacturer, including features and technical specifications. We’ll look at the most well-liked models and provide an estimated price.
