Short answer. Yes, a portable power station can run a gas furnace during a power outage, and you connect it through a listed furnace transfer switch. A PSC-blower furnace uses about 2,260 Wh per 8-hour night; the BLUETTI Elite 300 holds 2,562 usable Wh and costs $0.47 per usable Wh.

What the differences mean

A gas furnace burns gas for heat but its blower, inducer fan, igniter and control board run on 120 V. Outage Authority quotes an NRC Canada field measurement of 490 W for a PSC blower and 284 W for an ECM blower, plus a 75 W inducer from the LBNL model, so the furnace draws about 565 W (PSC) or 359 W (ECM) while the burner is on. On a mild night the furnace runs about half the time: 565 W × 0.5 = 282.5 Wh per hour, and an 8-hour night (UDPOWER's night length) is 282.5 × 8 = 2,260 Wh. At a design-low 77% duty that rises to 565 × 0.77 × 8 = 3,480 Wh; an ECM furnace on a mild night needs 359 × 0.5 × 8 = 1,436 Wh. Every station row above uses 85% of its rated Wh as usable (inverter losses and the low-battery cutoff), then divides: Elite 300, 3,014.4 × 0.85 = 2,562 Wh, 2,562 ÷ 282.5 = 9.1 h, 2,562 ÷ 2,260 = 1.1 nights, $1,199 ÷ 2,562 = $0.47 per usable Wh. The 85% figure is conservative for the two BLUETTI units: StorageReview metered 2.67 kWh out of the Elite 300 (89% of rating) and 1.91 kWh out of the Elite 200 V2 (92%).

Your furnace and outage	Energy per night	Fits
ECM blower, one mild night	about 1,436 Wh	Elite 200 V2 (1,763 usable Wh) with margin
PSC blower, one mild night	about 2,260 Wh	Elite 300 (2,562 usable Wh) or Growatt HELIOS 3600 (3,133)
PSC blower, one design-low night	about 3,480 Wh	DELTA Pro 3 (3,482 usable Wh) on one charge; Elite 300 covers 74% of it
Two or more nights with no grid	4,520 Wh and up	Recharge from a car or generator by day, or a 240 V-class battery; no row here holds two PSC nights

Buy stored capacity, not a panel

The solar kits look like the furnace-backup answer, but the arithmetic runs the other way in November. The BLUETTI Elite 200 V2 + 200 W kit is $1,199 today, exactly the price of the bare Elite 300. For that money the kit holds 1,763 usable Wh and the Elite 300 holds 2,562, 45% more. To put one mild PSC night back through the kit's 200 W panel takes 2,260 ÷ 200 = 11.3 hours of full-rated sun (7.2 hours for an ECM night), and a flat panel in a November sky delivers well under its rating for most of the day. The 2 × 200 W Elite 200 V2 kit ($1,499) halves that to 5.7 hours, and the Elite 300 + 2 × 200 W bundle ($1,699) gives the same 5.7 hours with the bigger battery. For a one- or two-night outage the money is better spent on Wh in the box; add panels only if outages at your address run past a weekend. The bare Elite 200 V2 at $899 is the value pick when 0.8 of a mild PSC night, or 1.2 ECM nights, is enough. $899 on bluettipower.com, $854.05 through this link: https://dealectric.com/go/bluetti-elite-200-v2

How to connect it

If the furnace has a cord and plug, unplug it from the wall and plug it into the station's 120 V outlet. Most furnaces are hardwired, and for those the listed path is a single-circuit furnace transfer switch mounted at the furnace: Outage Authority quotes Reliance's Easy/Tran TF151 at 1,875 W and TF201 at 2,500 W, both UL 1008, with Reliance's instruction that the switch 'should be connected by a licensed electrician or heating contractor'. You then run the station's cord to the switch's inlet and flip it from line to generator. Never backfeed a wall outlet with a male-to-male cord.

Test the setup with the station fully unplugged from the wall before the first outage. The Cool Down (Wyatt Fischer, 2026-09-16) reported an EcoFlow DELTA 3 Plus owner whose furnace would not behave as expected once the unit stopped passing through utility power and began supplying inverter power, because, in the owner's words, 'the neutral and ground are no longer bonded'. The same article relays warnings that using a bonding plug while the unit is still connected to the wall could violate code by creating a second bond and could damage the station. Outage Authority adds that the manuals it read for Jackery, Bluetti and Anker do not state whether the AC neutral is bonded, so the electrician installing the transfer switch is the one to settle bonding for your furnace.

Not recommended

The Elite 200 V2 + 200 W kit at $1,199 is the trap in this table: same money as the Elite 300, 800 fewer usable Wh, and a panel that needs about 11 hours of rated sun to replace one furnace night. The ALLPOWERS R4000 would match the Elite 300 on cost per usable Wh and hold 1.3 nights, but every variant is sold out on the maker store today.
