Uninterruptible Power Supply (UPS) for pellet stoves

Pellet stoves are an increasingly popular home heating solution, appreciated for their efficiency, energy savings, and low environmental impact.
However, like many other electronic devices, these systems are highly sensitive to power outages and voltage fluctuations, which can compromise their proper functioning and, in the worst cases, damage internal components.

To ensure continuous heating and protect your stove from blackouts or electrical disturbances, it is ideal to use a specific UPS for pellet stoves, fully compatible with this type of device.

Why to use a UPS for pellet stoves?

Modern pellet stoves are powered by an electronic control board that manages ignition, ventilation, combustion, and smoke extraction.
In the event of a power outage the stove shuts down abruptly, interrupting the combustion cycle.
This not only results in an immediate service interruption—especially during the colder months—but may also require manual cleaning of the brazier and a new ignition cycle that can take 15 to 20 minutes.

In the event of a blackout, the lack of a backup system can therefore lead to:

  • stove lockout
  • accumulation of unexpelled combustion residues
  • malfunction of the smoke extraction systems
  • potential damage to the electronic control unit

Equipping your system with a UPS for pellet stoves can help you avoid all these issues.
Now we just need to understand how to choose the right UPS for your stove!

UPS waveform

A pellet stove is a rather delicate device. Since it includes fans, motors, and sensitive electronic circuits, it cannot be powered by just any kind of UPS.

In order to avoid malfunctions, unexpected shutdowns, or damage to the stove’s electronics, it is essential to use a UPS with pure sine wave technology.
This type of Uninterruptible Power Supply can supply power identical to that of the domestic electrical grid, ensuring maximum compatibility with all major pellet stove models.

UPS sizing

Another crucial factor in choosing a UPS for a pellet stove is sizing, which means selecting the appropriate power capacity of the UPS.

Pellet stoves have variable power consumption and especially experience current spikes (inrush current) when fans and preheating resistors start. For this reason, it’s always advisable to oversize the UPS, choosing a model with at least double the nominal power of the stove.
For example, if the stove consumes 200 Watts during operation, then the UPS should have at least 400 Watts of real power, equivalent to around 700-800 VA.
Oversizing the UPS allows you to:

  • properly handle startup surges
  • avoid sudden overloads
  • increase overall autonomy
  • extend the UPS’s lifespan
