Uninterruptible power supply for the gas boiler ensures the operation of equipment in emergency situations that affect the function of the mechanism. Modern heating devices are equipped with electrical modules that regulate the operation of the equipment. Therefore, in case of power failure, the devices stop working. The solution is a UPS for the boiler, which will keep the system functioning for some time.

What is a UPS and why do you need it?
Many models of heating equipment must be constantly connected to the power grid in order to properly perform its functions. Items such as the circulating pump, ventilation, control unit and ignition system all stop working during a power outage. This causes the area being heated to begin to cool. In some cases, this contributes to irreversible equipment failure or life-threatening situations.
The UPS for the boiler not only maintains the operation of the heating system by accumulating energy, but also stabilizes the voltage parameters within the power grid. Electronic chips in the equipment are sensitive to voltage fluctuations, which reduce the period of operation of the mechanism.
Uninterrupted power supply for the gas boiler can provide special devices. They include 2 modules: a current stabilizer and a battery. The first equalizes the degree of voltage, eliminating its fluctuations. It also protects the battery when it is charged. The battery stores energy and provides it to power the boilers during disconnection of the device from the mains.
Advantages of using a UPS:
- Protection against voltage fluctuations. It 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's intervention. The process is fully automated.
- Uninterruptible power supplies have a long period of use, which ranges from 5 to 7 years.
- Ability to connect additionally other electronic devices.
UPS equipment varies depending on the company-manufacturer and the specified characteristics.
The main types of uninterruptible power supplies
The market offers uninterruptible power supplies for boilers in different price categories. The cost is calculated depending on the functionality of the device and the time of its autonomous operation.
Devices are classified according to the principle of operation into 3 large groups:
- linear-interactive;
- continuous;
- standby.
A distinctive feature of the linear-interactive models is the presence of a voltage regulator. The power of an uninterruptible power supply makes it possible 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. The more expensive models of the price category analyze the sine wave pattern and switch the power to the batteries when the indicator is distorted by 5-10%.
When you connect an uninterruptible power supply of the continuous type, the parameters of the electric network at the output do not depend on the incoming indicators. The equipment constantly uses the battery for power, regardless of the availability of electricity at the input. Power conversion is done in 2 steps:
- The input voltage is lowered and the alternating current undergoes a rectification process. The resulting energy is used to charge the battery.
- During recoil, electricity from the battery contacts is converted to alternating current, thereby increasing the voltage that is transferred to the output of the uninterruptible power supply.
The linear inverter for the boiler power supply what power to use, depends on the individual requirements of the appliances. Standard models allow autonomous operation 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 the UPS correctly
Uninterruptible power supply for the boiler is purchased taking into account the factors that will play an important role in the use of the device. In order not to get confused among the variety of models, manufacturers and characteristics of devices, it is necessary to accurately consider several parameters:
- The boundaries of the operating voltage range.
- The duration of operation in standalone mode.
- The possibility of connecting external batteries.
- The nature of the sine wave at the output of the device.
Competent selection of a UPS for a gas boiler also involves taking into account the power of the equipment and the number of batteries, which in the future can be connected to the device. The battery capacity directly affects the duration of the time interval of autonomous operation. Models with a low operating voltage threshold are suitable for country houses.
The connection diagram of the UPS to the gas equipment is simple. Additionally, it is necessary to purchase cables and an electrical switchboard. The output of the inverter is connected to the terminals of the heating equipment 220 V. Their location is specified in the datasheet of the unit.
The charge controller is connected to the network through special protective circuit breakers. After connecting the batteries, turn on the power and allow the batteries to fully charge. After this, check the autonomous operation time of the mechanism.
Rating of popular models
Before choosing a UPS, it is worth familiarizing yourself with the most commonly purchased models:
- INELT Monolith k1000lt can work autonomously for more than 10 hours. There are no built-in batteries, but a battery with a capacity of up to 150Ah can be additionally connected.
- The Stihl VOLTGuard HT1101L model has short-circuit protection and dual inverter.
- Uninterruptible power supply for boilers Bastion Skat-UPS1000 is used for boiler equipment and heating systems.
A variety of models will allow you to buy the necessary device to meet the individual requirements of the user.
