Backup Power Supply for Boiler and Circulation Pump

Wondering why your boiler room shouldn't be without a backup power supply for gas boilers or circulation pumps? If you own a boiler for wood or other solid fuel, you certainly know that these solid fuels burn for a longer time. Since they keep constantly heating your boiler, overheating can occur within minutes of the circulation pump stopping. This can cause welded joints to crack and even lead to a fire in the boiler's outer insulation. In such a case, a backup power supply for the circulation pump serves as prevention against unwanted damage to the boiler, or even to your entire property. It will provide enough electrical energy for several hours of operation during a power outage, keeping the controller or circulation pump running.

The importance of a backup power supply - not just for your heating

A key feature of a backup power supply is powering solid-fuel boilers in the event of a main power failure. The backup power supply instantly provides the boiler with energy from the battery, keeping the circulation pump running. This allows the boiler to cool down safely.

Operation of the backup power supply on battery is possible for several hours. However, it depends on the number of connected devices and their power consumption. If your home also has other electrical appliances that require stable power parameters, you can safely use this backup power supply to keep them running as well.

Some backup power supplies feature a loud alarm that sounds during a power outage. Most backup power supplies also include short-circuit protection - if such a risk is detected, the unit will stop operating. In addition, all backup power supplies include surge protection, which protects the boiler, controller, and circulation pump from voltage spikes.

Avansa 500W backup power supply for circulation pumps

Avansa 500W backup power supply belongs to a group of professional automatic backup power supplies suitable for circulation pumps. It is supplied together with a standard 12V Akuma Komfort Plus 46 Ah car battery. To extend the battery's service life, it is recommended to perform a full discharge-and-charge cycle at least once every two months. You should carry out this procedure even if there were no power outages during that period and the battery remained fully charged.

The main feature of this device is a pure sine wave output when running on battery power, identical to your home's main power supply. While mains power is available in your property, the backup power supply will charge the battery, ensuring its long service life.

It's important to note that the backup power supply only works when connected to an external battery. In the event of a power outage, it automatically switches to battery power, and this switchover is also shown on the unit's display. At the same time, an audible signal will alert you to the change. However, if you hear a rapid beeping alarm, the device is signaling that overload protection has been triggered. This usually happens when the load on the backup power supply exceeds 110% of its rated output. In that case, the unit will stop operating to prevent damage.

On the front of the Avansa 500W backup power supply you will find a display and an "On/Off" button. On the back, there is a power cable and two additional cables marked "+" and "-" used to connect the battery. There is also a fan, beneath which are two output sockets. Since this is a device carrying electrical voltage, you should never touch the battery terminals during operation. Also, keep it away from any fuel.

Backup power supplies are available in several versions depending on power output and battery. Units without a battery are also available. You can find our full range of backup power supplies on our website and if you need expert advice, feel free to contact us at info@atria.sk.

Frequently Asked Questions

• How long can a backup power supply keep the boiler running during a power outage? Runtime depends on the capacity of the connected battery (Ah) and the power draw of the boiler or circulation pump - typically a few hours, and considerably longer with a larger battery (46-55 Ah).
• Does the backup power supply switch on automatically? Yes, when mains power fails, the unit switches power to the battery instantly (within milliseconds), so neither the boiler nor the circulation pump stops.
• Is the backup power supply compatible with common gas boilers? Yes, Avansa units work with most household gas boilers as well as solid-fuel boilers - the only requirement is sufficient power output (W) for the given appliance.
• Can the capacity be increased later with an additional battery? On some models, yes - the battery can be replaced with a more powerful one or an external battery can be connected. We're happy to help you choose based on your boiler.
