Can the EcoFlow DELTA 2 Run a Gas Furnace Blower?
Yes. With 1,024Wh of LiFePO4 battery capacity (870Wh usable after 85% AC inverter conversion) and a 1800W continuous / 2700W surge pure sine wave inverter, the EcoFlow DELTA 2 should run a Gas / Propane Home Furnace Blower Motor for approximately 3.8 hrs on a single charge.
- Usable Watt-Hours: The EcoFlow DELTA 2 holds 1024Wh, which yields about 870Wh of 120V AC power, assuming ~15% DC-to-AC inverter loss.
- Gas Furnace Blower Duty Cycle: While active, a Gas Furnace Blower pulls 550W (with a 1200W startup spike). Over a multi-hour period, its 40% duty cycle averages ~220W per hour (plus ~8W inverter standby overhead).
- Tip: By installing a simple $95 single-circuit EZ Generator Switch next to your furnace, you can plug a 1,800W–2,400W portable power station directly into your gas furnace during a winter blackout. Because the furnace thermostat cycles the blower on ~40% of the time (~220W average hourly draw), a 2,048Wh station keeps your whole house warm for 8–10+ hours!
