How much electricity does a pellet stove use?<\/strong>
Most pellet stoves use 80\u2013150 watts while running, with a brief startup draw of 300\u2013500 watts.<\/strong><\/p>\n

Most pellet stoves require electricity to run the auger, combustion fan, and exhaust fan, even though they burn pellets for heat.<\/p>\n

If you\u2019re wondering how many watts or amps a pellet stove uses, or whether it can run during a power outage, this article answers both. I measured my own pellet stove\u2019s real-world power consumption and tested how to keep it running using a battery and inverter when the grid goes down.<\/p>\n

How Much Electricity Does A Pellet Stove Use?<\/h2>\n

First, as with all typical pellet stoves I\u2019m aware of, they require a 120-volt AC power source (typical in-home electricity) to run the auger and fans.<\/p>\n

Second, we need to discover the operational power consumption (watts) or the AC (amps) before figuring out what we need to run our pellet stove during a power outage.<\/p>\n

I am going to use my pellet stove, which is a Harman brand, as an example. This will likely be typical for most pellet stoves with fans and motorized auger.<\/p>\n

\"How<\/figure>\n

The electrical requirements listed in their spec sheet are as follows. However, I will give you real-world measurements afterward:<\/p>\n

Specifications:<\/strong>
Start up: 4.0 amps (460 watts)
Run: 3.0 amps (345 watts)<\/p>\n

My Real World measurements:<\/strong>
Start up: 3.0 amps (360 watts)
Run: 0.7 amps (80 watts averaged over time)<\/p>\n

Note: I am confident these specs are for everything full-on(all fans, auger speed, etc.) on the highest settings, plus a margin.<\/p>\n

My real-world measurements are less than that during regular operation. When the ignitor initially fires up, there is a brief condition (several minutes) of higher power consumption (the ignitor coil).<\/p>\n

How Many Watts Does a Pellet Stove Use?<\/h2>\n

Typical pellet stove wattage:<\/strong><\/p>\n

    \n
  • Startup (igniter): 300\u2013500 watts (5\u201310 minutes)<\/strong><\/li>\n
  • Running average: 80\u2013150 watts<\/strong><\/li>\n
  • Peak load (worst case): ~400\u2013500 watts<\/strong><\/li>\n<\/ul>\n

    My Harman \u2018Absolute 43\u2019 pellet stove draws almost 400 watts for a few minutes during the ignition period. Once lit and running, the average consumption was 80-100 watts, averaged over time.<\/p>\n

    While this example uses a Harman pellet stove, power consumption is similar across most modern pellet stoves with fans and augers.<\/p>\n

    How did I measure how many watts\/amps? Answer: I use the \u2018KILL A WATT\u2019 meter\u2026<\/p>\n

    I explain more about it in the following article:
    [ Read: How To Measure Energy Consumption Of Appliances ]<\/p>\n

    How Many Amps Does a Pellet Stove Use?<\/h2>\n

    At 120 volts AC:<\/p>\n

      \n
    • 400 watts \u00f7 120V \u2248 3.3 amps<\/strong><\/li>\n
    • 100 watts \u00f7 120V \u2248 0.8 amps<\/strong><\/li>\n<\/ul>\n

      Most pellet stoves draw less than 1 amp while running<\/strong>, but briefly spike higher during ignition.<\/p>\n

      On the 12-volt DC side (if using battery power and inverter), this equates to roughly 30\u201335 amps during ignition.<\/p>\n

      Do Pellet Stoves Require Electricity?<\/h2>\n

      Yes.<\/strong>
      Most pellet stoves require electricity to operate the auger and fans. Without power, they will not feed pellets or exhaust smoke unless connected to a backup power source.<\/p>\n

      Can You Run a Pellet Stove Without Electricity?<\/h2>\n

      A pellet stove cannot run on its own<\/em> without electricity \u2014 but it can be powered by a battery, inverter, or generator during a power outage<\/strong>.<\/p>\n

      How To Run A Pellet Stove Without Electricity<\/h2>\n

      Do you want to know how to run a pellet stove during a power outage? If you have a pellet stove and rely on it for heat, pay attention to this article. I\u2019ll show you how I measured my own pellet stove for watts\/power consumption and how I can run it during a power outage for a while.<\/p>\n

      Without electricity during the winter (severe storms, snow\/ice, high winds), your home or cabin will get cold quickly!<\/p>\n

      It\u2019s not that complicated to set this system up. I will first run through the calculations to exemplify a pellet stove\u2019s typical power consumption. Then, we\u2019ll see what we can do to keep it running during a power outage\/blackout.<\/p>\n

      12 Volt Battery & DC-AC Inverter For Pellet Stove<\/h2>\n

      Could you make your emergency backup power source so you can run a pellet stove during a power outage? You will need at least one deep cycle 12-volt battery and an inverter to convert 12-volt DC to 120-volt AC.<\/p>\n

      Use a pure sine wave inverter to avoid potential damage to sensitive control boards.<\/p>\n

      DC to AC Power Inverter Wattage for Pellet Stove<\/h3>\n

      The inverter you choose will have to produce at least the maximum load of your pellet stove. That would be 460 watts based on the Harman spec sheet or 360 watts based on my accurate real-world measurements. When specifying a system, looking at the worst-case scenario is always wise, so let\u2019s look for at least a 500-watt inverter.<\/p>\n

      The only time the inverter will be loaded down will be a few minutes after the ignitor is on. Otherwise, it will be cruising well below its rated maximum during regular operation.<\/p>\n

      I tested this 600-watt Samlex (because I already had it for other purposes). It worked great. However, it is somewhat expensive (albeit a high-quality inverter made in the USA).<\/p>\n

      The following choices from BESTEK (a reputable company) are good, cost-effective power inverters. You might also consider their 1,000-watt model, which may benefit other uses.<\/p>\n

      \"\"\"\"<\/figure>\n

      The following 500 watt inverter should get the job done, albeit nearly maxed out during the ignition phase:
      BESTEK 500 Watt Inverter on Amazon<\/p>\n

      My recommendation for an inverter is the following 1,000 watt BESTEK due to the margin it provides during pellet stove ignition:
      BESTEK 1,000 Watt Inverter on Amazon<\/p>\n

      Think of it this way: A 12-volt DC to 120-volt AC inverter can also power other devices. It\u2019s great for an emergency situation, simply powering something from your vehicle battery, etc.<\/p>\n

      12 Volt Battery to DC-AC Power Inverter Cables<\/h3>\n

      You might make your own cables to connect the battery to the inverter, or you might purchase one already made. Some DC to AC inverters may come with cables\/connectors for this.<\/p>\n

      How many 12-volt DC Amps to run a Pellet Stove<\/h4>\n

      My real-world measurements of my Harman pellet stove showed that it pulled nearly 400 watts during the ignition phase. Depending on the battery condition\/voltage, the 400-watt amperage conversion for a 12-volt battery may range from 32 to 34 amps.<\/p>\n

      Bear in mind that you will need a cable set that can carry the full amp rating of the inverter. For a 500-watt inverter, an 8AWG cable is generally sufficient.<\/p>\n

      You might use the following 8AWG jumper cables. Cut the cable set in half and strip the non-clamp ends to bare wire. This will insert into the DC input connectors of the inverter.<\/p>\n

      If you are serious about using the BESTEK 1000-watt inverter near its rated capacity, I recommend the following 4AWG cable set (note the different lengths) instead of the factory-included cables.<\/p>\n

      Battery For Pellet Stove During A Power Outage<\/h2>\n

      Now that you have an inverter, you will need a battery! Here\u2019s the critical thing to remember: The battery must have enough capacity to run your pellet stove for a reasonable period.<\/p>\n

      What does that translate to? A typical 12-volt \u201cdeep cycle\u201d marine-type battery will be rated for about 100 AH (Amp Hours). This will be displayed on the battery itself. And this will be your limiting factor regarding how long you can run your pellet stove.<\/p>\n

      Let me explain\u2026<\/p>\n

      If you are using a 100AH 12VDC deep-cycle battery and your pellet stove draws 100 watts on average, this battery will be 50% discharged in 6 hours.<\/strong><\/p>\n

      Formula:
      100 watts = 8.3 amps (100 W \/ 12 VDC)
      100 watts \/ 8.3 amps = 12 hours (fully discharged)
      12\/2 = 6 hours (50% discharged)<\/p>\n

      This assumes continuous operation; real-world runtime is often longer due to thermostat cycling.<\/p>\n

      Important: Never fully discharge a lead-acid battery. It will damage the battery. To prolong the battery\u2019s life, it is a rule of thumb not to discharge beyond 50% before recharging.<\/p>\n

      Note: Connecting two batteries in parallel (plus to plus and minus to minus) will double their capacity and run time.<\/p>\n

      Real-world pellet stoves cycle on and off, meaning actual runtime is often longer than continuous calculations suggest<\/strong>.<\/p>\n

      Use Your Car Battery To Run Pellet Stove Through an Inverter<\/h3>\n

      Another alternative would be to connect your inverter to your car battery. You can run an extension cord into your house to operate the pellet stove. You could start your vehicle now and again to charge the battery to keep your pellet stove running.<\/p>\n

      Frequently Asked Questions About Pellet Stove Electricity Use<\/h2>\n
      \n
      How much electricity does a pellet stove use per hour?<\/strong> <\/p>\n

      Most pellet stoves use about 80\u2013150 watts per hour while running<\/strong>. During startup, the igniter briefly increases power usage to 300\u2013500 watts for several minutes<\/strong>, after which electricity consumption drops significantly.<\/p>\n<\/p><\/div>\n

      Do pellet stoves use a lot of electricity?<\/strong> <\/p>\n

      No. Compared to other household appliances, pellet stoves use very little electricity<\/strong>. Even when running continuously, the electrical cost is modest because the stove\u2019s heat comes from burning pellets, not electricity.<\/p>\n<\/p><\/div>\n

      Do pellet stoves require electricity to operate?<\/strong> <\/p>\n

      Yes. Most pellet stoves require electricity to power the auger, combustion fan, and exhaust fan<\/strong>. Without electricity or backup power, the stove will not feed pellets or vent exhaust gases.<\/p>\n<\/p><\/div>\n

      Can a pellet stove run without electricity during a power outage?<\/strong> <\/p>\n

      A pellet stove cannot run on its own<\/strong> without electricity. However, it can be powered during a power outage<\/strong> using a battery and inverter, generator, or other backup power source.<\/p>\n<\/p><\/div>\n

      How many watts does it take to run a pellet stove?<\/strong> <\/p>\n

      Most pellet stoves require:
      300\u2013500 watts during ignition<\/strong>
      80\u2013150 watts while running<\/strong>
      Designing a backup system with a 500\u20131000 watt inverter<\/strong> provides sufficient capacity and safety margin.<\/p>\n<\/p><\/div>\n

      How many amps does a pellet stove use?<\/strong> <\/p>\n

      At 120 volts AC:
      Running: ~0.7\u20131 amp<\/strong>
      Startup: ~3\u20134 amps<\/strong>
      On a 12-volt battery system, startup can draw 30\u201335 amps<\/strong> briefly during ignition.<\/p>\n<\/p><\/div>\n

      Will a pellet stove work with a battery backup?<\/strong> <\/p>\n

      Yes. A pellet stove can run on a 12-volt battery paired with a DC-to-AC inverter<\/strong>. Runtime depends on battery capacity, inverter efficiency, and how often the stove cycles on and off.<\/p>\n<\/p><\/div>\n

      How long can a pellet stove run on a battery?<\/strong> <\/p>\n

      A typical 100Ah 12-volt deep-cycle battery<\/strong> can run a pellet stove for about 6 hours at 50% discharge<\/strong>. Actual runtime is often longer because pellet stoves cycle rather than running continuously.<\/p>\n<\/p><\/div>\n

      Are pellet stoves safe to run on an inverter?<\/strong> <\/p>\n

      Yes, provided you use a pure sine wave inverter<\/strong> with sufficient wattage capacity. Pure sine wave inverters help protect sensitive electronics in modern pellet stove control boards.<\/p>\n<\/p><\/div>\n<\/p><\/div>\n
