Wood stove/insert Efficiency Question

[Rcr72]

I'm trying to decide between two inserts:

1) Lopi Revere
Emissions: 1.9 grams per hour
Steady State Efficiency: 75%
Made in: USA

2) IronStrike (Lennox) Performer C210
Emissions: 4.2 grams per hour
Heat Transfer Efficiency: 85%
DEQ Efficiency: 67.1%
Made in: Unknown


My quesions:

1) I'm confused by the efficiency numbers. Does one look better than the other here?

2) For similar sized stoves/inserts, is 4.2 grams/hour vs 1.9 grams/hour significant?

3) Does anyone know where IronStrike (Lennox, formerly Country Stoves) are made?

Thanks for any insight

Both are going to put the heat into your home. The Lopi is a bit cleaner burning which indicates a little higher combustion efficiency. Lopi Stoves are made in Mulkilteo, WA. Country Stoves are made about 50 miles south of there in Auburn, WA.

The EPA list of certified stoves estimates both of them as capable of 63% average efficiency. Neither of them appear to have been officially tested. Look under Travis Industries for the Lopi Revere.
