An uninterruptible switch for a gas boiler ensures the operation of equipment in emergency situations that affect the performance of the mechanism's functions. Modern heating appliances are equipped with electrical modules that regulate the operation of the equipment. Therefore, when there is a power outage, the devices stop working. The solution to the problem is a UPS for the boiler, which will support the functioning of the system for some time.

What is a UPS and why is it needed
Many models of heating equipment must be constantly connected to the mains in order to properly perform their functions. Elements such as a circulation pump, ventilation, a control unit and an ignition system completely stop working during a power outage. This leads to the fact that the heated area begins to cool down. In some cases, this contributes to the irreversible breakdown of equipment or the occurrence of life-threatening situations.
The UPS for the boiler not only supports the operation of the heating system due to the stored energy batteries, but also stabilizes the voltage parameters within the power grid. Electronic chips in the equipment are sensitive to voltage drops, which shorten the period of operation of the mechanism.
Uninterrupted power for a gas boiler allows you to provide special devices. They include 2 modules: a current stabilizer and a rechargeable battery. The first equalizes the degree of tension, excluding its fluctuations. It also protects the battery when it is charging. The battery stores energy and provides it with power to the boilers during the disconnection of the device from the mains.
Benefits of using a UPS:
- Voltage surge protection. This reduces the cost of new equipment to replace the old one.
- The process of installing and configuring the equipment is simple and does not require special skills.
- Control of electrical network parameters does not require user intervention. The process is fully automated.
- Uninterruptible power supplies have a long period of use, which ranges from 5 to 7 years.
- Possibility to connect additional electronic devices.
The configuration of the UPS varies depending on the manufacturer and the specified characteristics.
The main types of uninterruptible power supplies
Uninterruptible power supplies for boilers of various price categories are presented on the market. The cost is calculated depending on the functionality of the device and its battery life.
Devices are classified according to the principle of operation into 3 large groups:
- line-interactive;
- continuous;
- reserve.
A distinctive feature of linear-interactive models is the presence of a voltage stabilizer. The power of the uninterruptible power supply allows you to install it at the entrance to the room. The switching interval is from 2 to 10 ms and does not affect the operation of the equipment in any way. Models of a more expensive price category analyze the type of sinusoid and switch power to batteries when the indicator is distorted by 5-10%.
When connecting an uninterruptible power supply of a continuous type, the parameters of the electrical network at the output do not depend on the incoming indicators. The equipment constantly uses the battery for power, regardless of the presence of electricity at the input. Electricity conversion is carried out in 2 steps:
- The input voltage is reduced, and the alternating current goes through the process of rectification. The resulting energy is used to charge the battery.
- During the return, the electricity from the battery contacts is converted into alternating current, thereby increasing the voltage that is transmitted to the output of the uninterruptible device.
The linear inverter for the power supply boiler of which power to use depends on the individual requirements of the devices. Standard models allow you to work autonomously from 10 to 30 minutes. During this time, the user can correctly leave the equipment, preventing damage to the control board of the device.
How to choose and connect a UPS
An uninterruptible switch for a boiler is purchased taking into account factors that will play an important role in the process of using the device. In order not to get lost among the variety of models, manufacturers and characteristics of devices, you need to accurately consider several parameters:
- The limits of the operating voltage range.
- Duration of work offline.
- Ability to connect external batteries.
- The nature of the sinusoid at the output of the device.
A competent choice of a UPS for a gas boiler also involves taking into account the power of the equipment and the number of batteries that can later be connected to the device. Battery capacity directly affects the length of the time interval of offline operation. For country houses, models with a low operating voltage threshold are suitable.
The scheme for connecting the UPS to gas equipment is simple. Additionally, you need to purchase cables and an electrical panel. The inverter output is connected to the terminals of the 220 V heating equipment. Their location is indicated in the unit's data sheet.
The charge controller is connected to the network through special circuit breakers. After connecting the batteries, turn on the power and allow the batteries to fully charge. After that, check the battery life of the mechanism.
