Upgrading for efficiency?

[Tim_J]

I've got an old Pelpro HHPP2BD that came with my house. It's been solid, I just replace the igniter once a year and have had no other issues. I can't find any ratings on the current stove but I'm guessing 65% and a new ComfortBuilt hp54 is rated at 84%.
I'm wondering if I should replace this stove with a new high efficiency stove? Does that extra 20% equate to any real savings?

85 % one should qualify for a tax credit. Double check that. So for numbers sake say new cost is 4000$ 30% is 1200. Burn 2 tones a year say 500$ save 20% or 100$ a year. 4000-1200= 3800 or 38 years to pay it off. Old unit won’t last forever. You may burn more than 2 tons.
Buy insulation and/or a heatpump would be better money in my opinion.

All that figuring takes the fun out of buying a "certain must have" or new car too.
