Compare Harman P43 vs PelPro PP130
Harman P43 vs PelPro PP130 Premium name or bigger numbers
Both are freestanding pellet stoves sold under Forge & Flame. On the EPA listings the PelPro PP130 is ahead on output (40,637 against 33,252 BTU/hr), efficiency (82% against 77% HHV) and emissions, for less than half the Harman's starting price.
Where to buy: no retailer links on this page yet. Prices below are the makers' own figures on the date shown.
Short answer: On certified numbers and price, the PP130 wins clearly. The P43 is the choice if you value Harman’s dealer network and reputation enough to pay about $2,600 more at starting prices. The EPA test doesn’t measure build quality or service life, so this comparison can’t settle that part.

Where They Differ
Tested output. The PP130 runs 9,605 to 40,637 BTU/hr; the P43 runs 18,783 to 33,252. The PP130 turns down to about half the P43’s lowest output, which matters in shoulder season, and reaches about 7,400 BTU/hr higher at the top.
Efficiency and emissions. 82% vs 77% HHV, 0.53 vs 1.8 g/hr of particulate and 0.16 vs 1.866 g/min of carbon monoxide, all in the PP130’s favor. Both are under the 2.0 g/hr limit.
Hopper. 130 lb for the PP130 (330 lb with PelPro’s PPHE200 extension) against 50 lb for the P43. For most owners that’s the difference between filling once a day and filling twice.
Advertised numbers. Both product pages print a heat input figure as “heat output”: 45,200 BTU/hr for the P43 and 49,200 for the PP130. Both manuals or spec tables label them correctly as input. The PelPro page also leads with “87.5% efficiency,” its LHV figure.
Price. Forge & Flame lists the P43 “starting at $4,449” and the PP130 “starting at $1,819,” both before installation.
Who Each One Suits
The PP130 suits a buyer who wants the most certified heat and efficiency for the money and likes the idea of a once-a-day fill. It comes up constantly on r/PelletStoveTalk for exactly that reason.
The P43 suits a buyer who wants to buy through a Harman dealer for installation and service and is comfortable paying for that. On the EPA numbers alone, it doesn’t outperform the PP130.
Common Questions
Why does Harman say 45,200 BTU when EPA says 33,252?
45,200 BTU/hr is heat input: the energy in the pellets the stove can feed per hour. Harman’s spec table labels it as input (23,900 to 45,200 BTU/hr); the product page calls it heat output. The EPA figure is measured heat output. See stove BTU ratings explained.
Is the PP130 really 87.5% efficient?
That’s its LHV figure. The PelPro manual gives 81.9% on the HHV basis, which matches the 82% EPA listing. The Harman’s equivalent figures are 82.7% LHV and 76.7% HHV.
How long does a hopper last?
It depends on the burn rate. At full input (45,200 BTU/hr for the P43, 49,207 for the PP130) and the USDA figure of 16.4 million BTU per ton of premium pellets, about 8,200 BTU per pound, the P43 feeds roughly 5.5 lb an hour and the PP130 about 6 lb. That empties the P43’s 50 lb hopper in about 9 hours and the PP130’s 130 lb hopper in about 22 hours on high; on low, much longer. These are our estimates from the published figures, not maker claims.
