Modern gas heating systems are powered by electricity, which means they need additional protection against power outages. Sensitive components of automatic gas boilers often fail, and in order to prevent this trouble, it is necessary to choose the most reliable, efficient uninterruptible power supply.
Further, the experts have selected for you the most effective ways to help you choose an excellent device that will last for many years without breakdowns and other problems.

What is a UPS, how it works
A UPS or an uninterruptible power supply is equipment that interacts with primary current sources and stabilizes it to prevent the failure of other devices and units powered by electricity. Uninterruptible power supplies are actively used for computer equipment and gas equipment, and each type of equipment requires its own version of the UPS, according to the technical characteristics of the equipment.
UPS systems are not designed the same and choosing the wrong type of system for your gas boiler can have disastrous consequences. Before choosing a UPS system, it is important to take the time to study the technical specifications of the boiler.
For example, the type of cooling fans installed in UPS systems can range from small, inexpensive boilers to large heating systems used in large rooms or warehouses.
Because a UPS contains sensitive electronics as well as batteries, proper airflow and cooling design is critical.
UPS pros and cons
The main advantage of any type of UPS is current stabilization, which means preventing equipment failure, the repair or replacement of which will be a costly and time-consuming process.
The disadvantages of the UPS include sensitivity to operating conditions.
If your environment is aggressive, make sure the device can be sealed or at least covered with electronics to protect the internal electronics. Be sure to check your UPS outputs and make sure the cooling systems are capable of handling your heat output.
The weakest link in a UPS system is its batteries, and elevated temperatures can significantly shorten its lifespan. In fact, it's estimated that for every 15 degrees above 25C, battery life is halved.
UPS types
Experts classify uninterruptible current supply devices for heating systems into several categories depending on the principle of operation, type of installation and the availability of additional options.
But since the main nuance in choosing a device is precisely the technical characteristics, the following types of UPS are most often distinguished:
- regular or reserve. They are also called offline devices.Such devices provide backup power and become necessary in the event of a power outage. The advantages of such devices include low price, compactness, the ability to install on a wall or put on the floor. But the disadvantages include limited functionality, in particular, backup models do not stabilize the voltage of the electric current.
- with stabilizer. AVR stabilizer device is characterized by the presence of a voltage rectifier, however, it is basic, the simplest. The battery capacity is small, the reserve of the device is only enough for 20 minutes of operation of the boiler when the power is turned off. But it is possible to connect an additional battery (external), in which case the power will increase, and the device will provide up to 10 hours of operation without power supply.
- Online systems. This is a modern solution in the issue of voltage stabilization and are considered the most reliable models. A double converter, consisting of an inverter, batteries and a power supply, converts AC to DC, and then back to AC, but during processing, the device makes the current stable. When the power is turned off, the uninterruptible power supply system runs on batteries and continues to ensure efficient operation of the heating unit for a long time.
How to choose a UPS
When choosing a UPS for your heating system, you should adhere to two points. First, you must consider that for long-term operation with circulating pumps, models with an approximated sinusoid or square wave are not suitable. These are budget models that immediately catch your eye when you visit a store or an online store with their attractive price.
The choice of models of the budget segment is only valid if your heating system is of the gravitational type, it does not have motorized elements. The second important point is the fact of the phase dependence of most modern boilers. They do not turn on without the neutral required by the technical characteristics of the boiler.
This problem can be solved, but this will entail additional costs, incl. it is better to exclude it at the initial stage by choosing the right UPS that matches the technical characteristics of your heating unit.

Expert advice
Set load priorities
It is very important to take the time to properly understand your current and future device loads. Most often, the UPS is used to support conventional oversized gas boilers used in apartments, which have a clean and stable load profile, in which case the UPS requirements are minimal.
But in the case of overall systems, you need to approach the choice more carefully. Reactive loads, compressors, electric motors and similar loads have their own power requirements and should be considered prior to selecting your UPS. Find out the load type of your heating boiler before you go shopping for a UPS.
Understand your energy infrastructure
Your power infrastructure is an important part of choosing a UPS. Take the time to review your existing power distribution.
These questions can clarify the power quality in your building:
- Are there frequent power outages, sags or power surges?
- Have there been any electrical problems in the last two years?
- How stable is your utility provider?
- Do you have neighboring businesses that could disrupt your own facility's power supply?
UPS maintenance considerations
Experts estimate that the initial capital cost of a UPS system is only 50% of the true UPS life cycle cost. After the warranty period expires, the UPS may require maintenance, replacement of batteries, capacitors and fans.
Low cost UPS options typically require three batteries to be replaced during their life cycle.Check what type of battery your chosen device requires and see what the standard warranty and battery life expectancy are. If you have the option to purchase an extended warranty, this may help offset or reduce some maintenance costs.
Finally, some manufacturers are still trying to control their service market by installing proprietary software in their UPSs. If a UPS manufacturer keeps its software off-limits to the public or vendor-neutral service providers, this may result in increased service costs and limited future service options.
Efficiency is also a key component of the life cycle cost of a UPS system. An inefficient system can cost you thousands of dollars over the life of the plant.
While some device manufacturers advertise their high reliability through the use of ECO or standby modes, make sure you test their true online AC efficiency as most sites will require a true online system to operate.
Choosing the right uninterruptible power supply is an important decision that can have a significant long-term impact on your business. Understanding these five considerations can guide you towards the best UPS for your team.
FAQ
To ensure the smooth operation of the gas boiler and avoid possible breakdowns, a UPS is necessary even in a small living space.
No, not all, but only models specially designed for this purpose. Redundant models only provide backup power.
Choose the type of UPS should be based on the technical characteristics of your heating unit. But as practice shows, online systems with a double current converter have proven themselves the most well.
Like any electronic device, the UPS requires special operating conditions, in particular, the device does not respond well to moisture and elevated room temperatures.
Here it is necessary to take into account the technical features of the heating unit. So budget models can be considered for a gravity system, while the circulation type is not compatible with a meander and an approximated sinusoid.
UPS today is a necessary equipment to avoid breakdown of the gas boiler. Interruptions in power supply can range from a slight surge, which will not cause serious damage to the heating system, to a significant impact on the automation of the boiler, which will lead to the need for costly repairs or even replacement of equipment.
Therefore, choosing the right UPS is a rational decision that helps save the family budget, time and nerves in the future.
