Inverter for circulation pump

Maintaining comfort and lowering energy expenses in your home requires effective insulation and heating. The circulation pump is an important part of an optimal heating system, among its many other components. Regardless of the real demand for heating, these pumps have historically operated at a fixed speed and consumed a constant amount of energy. But with more control and energy efficiency, inverter technology has completely changed this part of heating systems.

An inverter for a circulation pump works by modifying the pump motor’s speed in accordance with the home’s heating needs. Inverter pumps have the ability to dynamically change their speed in contrast to conventional pumps, which operate continuously regardless of whether heating is actually required. This implies that they may increase or decrease in response to variables like the outside temperature, the demand for heating within, and the features of the heating system.

Energy savings is one of the main advantages of utilizing an inverter for your circulation pump. Compared to their conventional counterparts, these pumps use less electricity because they operate at different speeds. The pump lowers energy consumption by slowing down when there is less demand for heating. On the other hand, the pump accelerates to meet the demand for greater heat. In the long run, this adaptability is a cost-effective solution because it reduces utility bills in addition to saving energy.

Inverter pumps not only save energy but also provide better comfort and functionality. Conventional pumps occasionally produce noise, particularly when operating at maximum speed. On the other hand, because inverter pumps can change their speed in response to demand, they run more quietly. As a result, the constant hum of a fixed-speed pump is eliminated, creating a more tranquil atmosphere inside the house.

When it comes to home insulation and heating systems, inverters for circulation pumps are revolutionary. Instead of operating at a constant speed all the time, these ingenious devices optimize energy consumption by adjusting the pump’s speed in accordance with the actual heating demand. With the help of inverters, you can save energy, lower your electricity costs, and prolong the life of your pump by precisely adjusting the pump’s output to the demands of your heating system. They also guarantee constant heating levels, which makes the interior environment more comfortable. Inverters for circulation pumps are a wise investment for anyone trying to increase the longevity and efficiency of their home heating system because of their efficacy and efficiency.

Working principle and design

The goal of every circulation pump is to initiate the forced water circulation in a closed heating system. Their construction is similar to a sump pump’s, and the non-corroding metal used for the casing is an alloy. It may be made of aluminum, steel, cast iron, brass, or bronze. An electric motor and rotor are parts of the pump’s configuration. The paddle wheel-shaped impeller on the rotor shaft is composed of ceramic or steel. The rotor is started by an electric motor.

After it is installed in the system, the circulation pump uses centrifugal force to pressurize the liquid by sucking it from one side and forcing it from the other. The impeller rotates, creating centrifugal force. The cistern’s water level will remain constant if the pump is operating at an even pace. It turns out that improving heating and increasing pressure require more than one of these pumps.

Equipment used for circulation needs to be connected here. It will assist the liquid in overcoming the resistance found in various system components.

Therefore, the absence of a circulation pump results in higher heating fuel consumption and associated expenses.

Possible problems

Remember that the pump is an energy-dependent device, meaning that it stops working and the room stops heating when there is no electricity. When the water begins to overheat, the heating system as a whole frequently malfunctions. There are multiple approaches to resolving this issue.


It is possible to get around the issue of power outages by just adding bigger diameter pipes to the current system. In this system, gravity moves the liquid around naturally. Regulating such a system is difficult, though.

A generator is another option. Nonetheless, the generator needs particular operating circumstances, such as having a designated location and a constant fuel level. Usually, this involves financial resources and is risky. Voltage surges may occur while the boiler is operating, and these could cause the electronic control system to malfunction.

Using an uninterruptible power supply (UPS) to solve the problem is far more practical and simple. "Uninterruptible" switches on by itself when there is no power, ensuring that the system will function regardless. Any room can have UPS equipment installed, and it requires no special maintenance other than replacing the batteries every two to three years. A device like that runs very quietly. It should be mentioned that installing a UPS is significantly less expensive than purchasing something like a generator.

Nuances of the operation of "uninterruptible"

But there are subtleties even here. The UPS typically outputs a voltage that is constant, but the pump needs precisely the opposite kind of voltage. As a result, an inverter—a type of current converter—must be purchased in order to use the "uninterruptible."

To guarantee that the circulation pump runs, an inverter is a necessary part of the heating system.

Modern UPSs typically consist of an inverter and a battery (or possibly more than one). The following are the benefits of the UPS, which has an inverter:

  • A pure sine wave is created, thanks to which the circulation pump functions;
  • energy saving;
  • The ability to increase the number of batteries used;
  • Automatic switching on in case of power outages and in general ease of operation.

Classification of "uninterruptible power supply"

There are various UPS types available:

  • Linear type – the simplest, it does not have a voltage stabilizer. If there is a power outage, the device automatically connects to the battery power;
  • line-interactive uninterruptible power supply source. It contains a simple stabilizer and from one to four batteries, the charge of which the system controls itself. In devices of this type have a lower internal voltage.

The process for setting up a UPS with an inverter is directly related to the device’s model. These 12/220 voltage converters differ in the kind of automation that controls the installation procedure.

As a result, some units are fixed directly to the pumping equipment’s motor. An additional kind of uninterruptible power supply can only be mounted on the wall and is limited to operating in a vertical orientation. Additionally, there is an impressively large, rectangular uninterruptible power supply. The automation of this kind is situated close to the circulator. Using the instructions, they can connect the 12/220 voltage converter manually as well.

Inverter for a heating pump – do it yourself or buy a ready-made one?

Everyone knows that a home cannot exist without a heating system in the modern era. This element receives a lot of attention as a result. Nonetheless, errors can occur during the planning and installation of the heating system.

Specifically, a circulation pump is often added to contemporary heating systems (learn more about them and how to choose one here). And it appears that everything is in order because this gadget increases the activity of coolant circulation through the pipes, leading to faster and better-quality home heating. However, a lot of people overlook the fact that the pump is an energy-dependent component of the system. However, generally speaking, only bring it up during a blackout. Consequently, the house cools down gradually because the coolant is unable to circulate.

This problem can be resolved in two different ways.

To start with, you can purchase a generator, which can supply the essential electricity. However, using the generator presents some challenges. The location for installation must be carefully chosen and furnished. Additionally, there are unique operating requirements, such as the requirement to routinely top off the fuel tank, and so forth. And how easily would a child be able to handle the situation if the house’s electricity went out when he was the only one there? Consequently, investing in a specialized UPS (UPS) is a more sensible way to address the circulation pump’s power supply problem.

Nevertheless, in the majority of instances, this kind of apparatus can generate a steady voltage, whereas the complete functioning of the pump requires a variable voltage. Therefore, an inverter should be added to the uninterruptible power supply.

What it is?

The sine wave needs to be pure.

A DC to AC converter is called an inverter. Furthermore, your battery-operated circulation pump will not function at all without it. That is, in essence, a UPS—a power inverter—supplied by one or more batteries and required for equipment to continue operating when the primary power source is disconnected.

Crucial to remember is that all pumps—regardless of brand—run on sine waves.

And there could be very bad outcomes if you don’t follow this guideline to the letter, as the sinusoid will become warped. That is to say, the energy-independent boiler may overheat because the pump will just be unable to pump water. This implies that further, very costly repairs will be needed.

There are numerous benefits to using an inverter, including:

  1. Significant (up to 40%) reduction in electricity consumption – and considering the fact that sometimes the pump runs on a battery, this is important.
  2. Creation of a pure sine wave, which is necessary for the quality work of the pump.
  3. Automatic switching on the power supply from the battery when the main power supply is switched off.
  4. It is possible to increase the number of batteries used.
  5. Easy installation and operation.

The type of device will determine how the inverter is installed. Today’s market offers a wide variety of models made by various manufacturers. Specifically, some inverters are mounted directly on the pump motor, while others need to be wall mounted in a precise location (usually vertically). Additionally, there are models of inverters—impressive, rectangular devices—that are mounted in close proximity to the circulation device.

The inverter’s connection is very easy to make. It is possible to complete it on your own; the most important thing is to carefully read the instructions and rules before starting the installation. Those who are unsure of their own abilities can, therefore, invite an expert.

What to consider when buying?

When choosing an inverter for a heating circulation pump, keep in mind that purchasing a pre-made item is preferable. It has specific requirements, meaning you can choose a unit that precisely fits your pump.

Naturally, there will be "skillful people" who will argue that the pump’s inverter can be modified from an automobile inverter. It is feasible to remake, yes. However, the challenge lies in attaining rigorous adherence to every requirement, particularly with regard to the sinus’s power and purity.

Because the prices of the inverters available on the market vary greatly, every customer can find a model that works well for them.

It’s crucial to utilize an inverter in a circulation pump’s electrical supply system. Ultimately, the apparatus will assist in mitigating electricity expenses while simultaneously safeguarding your pump against numerous issues that may arise from variations in voltage or insufficient electricity.
