An effective heating system is essential for keeping your house warm and comfortable during the winter. Especially for closed-loop heating systems, the expansion tank is an essential part of a heating system. As the water in the heating system heats up and expands, pressure fluctuations happen, and the expansion tank helps control them. With an emphasis on the Expanomate expansion tank, we’ll discuss the significance of the expansion tank and walk you through the installation process in this post.
Let’s start by discussing the need for an expansion tank in your heating system. A closed-loop heating system heats water and circulates it through pipes to distribute warmth throughout your house. The expansion of the heated water results in a rise in system pressure. If there isn’t a way to handle this expansion, the pressure might rise to an unsafe level and harm the boiler and other system parts as well as pipes and valves. The expansion tank is useful in this situation.
By acting as a buffer and allowing the heated water to expand into the tank as it heats up, the expansion tank keeps the system from building up too much pressure. Expanomate expansion tanks are made especially for this kind of application, providing a dependable and effective way to keep your heating system’s pressure levels at ideal levels. It is the perfect option for both residential and commercial heating systems because of its strong construction and creative design.
Let’s now explore the installation procedure of an Expanomate expansion tank for your heating system. Installation is a manageable task with the correct guidance, despite the fact that it may seem intimidating, particularly if you’re unfamiliar with plumbing or HVAC systems. The first step is to determine the expansion tank’s size based on the needs and specifications of your heating system. Make sure to choose the tank size that best suits your needs from the variety that Expanomate offers to accommodate various heating configurations.
Finding the perfect installation location comes next after you have the correct expansion tank. Installing the tank on the heating system’s supply side is recommended; it should be done closest to the water heater or boiler. To avoid any possible mishaps or damage, it is crucial to make sure the tank is positioned vertically and firmly fixed to a stable surface.
Connecting the expansion tank to the heating system is the last step after it has been installed. This usually entails using the proper fittings to attach the tank to the system’s pipework and making sure that every connection is tight and leak-free. To guarantee best performance and safety, it’s also essential to adhere to the manufacturer’s installation instructions and suggestions.
To sum up, installing an expansion tank, such as the Expanomate, is essential to preserving the longevity and effectiveness of your heating system. Your heating system will run smoothly all year round thanks to the expansion tank’s ability to adapt to changes in pressure. This helps shield your system from expensive damage.

An open expansion tank, where air exits the pipelines during water filling and compensates for thermal expansion of the water, is a standard feature of any heating system that uses convective circulation or another form of gravitational heat supply.
However, leaving the tank open while the heat supply is running has drawbacks because it allows the heat carrier—water—to evaporate and becomes saturated with airborne oxygen. The water in the tank vaporizes, requiring frequent additions of water. Additionally, an excess of oxygen-rich water oxidizes the metal surfaces of the pipes, heating devices, and heat-reproaches that make up the heating system, reducing the system’s overall operating time.
A straightforward conversion of the open heat supply to a closed system is the only way out of this predicament. Convective circulation as a principle is maintained; that is, the heat carrier will circulate as a result of the physical characteristics of heated and cooled water, but only if the process passes through a closed pipeline under extreme pressure.
The installation of a circulation pump and this well-executed modernization will provide the old system with all the benefits of a state-of-the-art heat supply.
Transfer to a closed heating system
Dismantling the expansion’s open tank, installing the security group, and removing the expansomate for heating are all part of the transfer to the closed system. To ensure a sufficient supply of heat, it is imperative to select an expansomate at the outset of the project and accurately calculate the volume of all constituents, including pipes, heating devices, and heat generators.
Expandomat for warmth-related purposes
The device for measuring pressure, the protective valve, and the automated Maevsky crane are all part of the security group. However, the group is expensive, and you can put it together yourself to cut costs.

Think about any of these:
1. Valve for protection. keeps heating systems and hermetic containers from raising the potential pressure.
They can be used in a wide range of conditions because they are produced with the most diverse factory targeting.
This method of selecting the heating system’s pipes is also fascinating.
Most of the time, "explosives" with a 3.5 bar limit are used in heating systems; however, you should follow the boiler manufacturer’s recommendations when choosing a valve. The majority of steel boiler manufacturers advise against using steel heat generators at hydraulic pressures higher than 1.5 bar, if not outright prohibit it.
As a result, the valve needs to be chosen with the 1.5 bar line for the operation if a steel boiler is chosen for heating.
2. A tool to measure the pressure’s magnitude. serves as a fluid or gas pressure indicator. Since the heat supply continues to function even under extreme pressure, its value is controlled by employing a device to measure the pressure’s magnitude.
3. Maevsky’s automated crane. It is a machine that automatically extracts air from a pipeline or sealed container.

The most frequent malfunctions of the heating system
1. When the water analysis opens the tap, the boiler’s combined valve (safety and reverse, in one instance) crackles.
Reason: The boiler’s expansomat showed a pressure of 3.0 atm when air pressure was measured, while the 2.5 atm system showed a pressure of cold water.
Elimination: You must lower the pressure to 2.0 atm by frightening the air out of the expansomate. The cracking of the valve stopped.
2. Occasionally, a boiler that is operating steadily and normally will abruptly shut off, reporting the error "No water pressure." Simultaneously, the boiler’s hydraulic pressure gauge indicates a steady pressure that is adequate for the boiler to operate. The heating system pressure sensor malfunctioned, which is the cause of this issue. It has to be changed, either by you or by a professional from the boiler service center.
But what if something like this happened: it’s cold outside in the yard in the evening, the boiler isn’t working, and there isn’t a replacement sensor? Here is where you can use a little trick: you need to shorten the pressure sensor’s contacts by inserting a jumper, which is a tiny piece of copper wire. In this instance, the control board receives a signal indicating the system’s maximum pressure, allowing the boiler to operate. The suggested fix for the boiler error is merely a stopgap measure; it does not negate the need to replace the sensor.
3. On a double-circuit boiler, the pressure in the heating system drops significantly when the hot water is turned on; as a result, the boiler does not enter the heating mode. Such a malfunction may occur for one of two reasons: – The boiler’s expansion tank membrane has ruptured, resulting in a loss of impermeability. – There is a defect in the heat exchanger, causing leakage from the heating circuit to the water supply circuit. Boilers with a steel-beeter heat exchanger are prone to this malfunction.
To eliminate this malfunction, you need to turn off the expansomate from the boiler and measure the pressure in the air cavity. If the pressure is 0 bar and it is not possible to pump air into it (the air will go through the hydraulic fitting), then the tank should be changed. Very often it happens that it is difficult or impossible to choose an expanomate appropriate to the cauldron. In this case, you can install an expansion tank, the corresponding volume, outside the boiler, connecting it to the return line and drowned out a flexible eyeliner to the regular tank. If the pressure in the expansion tank corresponds to the norm, then there is a leak in the heat exchanger and it must be replaced.
4. A noticeable discrepancy in the boiler’s feed temperature and return is evidence that the circulation pump, when operating at its lowest speed, is not inadequately accelerating the coolant. Working at speeds of two and three results in normal circulation.
Sometimes the engine stops producing the necessary number of revolutions when the pump’s first speed is wound with short, closed turns, which deteriorates circulation. However, there are no issues when working at the second or third speed because circulation remains normal. In this situation, a working circulation pump can be used instead of leaving it running at high speeds.
5. The boiler does not turn on when you try to turn it on, and the indicator shows an error.
Reason: The boiler control’s power current was not phased correctly. Elimination: Alter the power’s phasing. All that needs to be done to accomplish this is to unfold the fork in the electric network outlet.
