Yes emissions reduction is correct. All wood heaters require 50 hours of conditioning prior to emissions tests.So, emissions will be better.
How much will the lifespan be increased?
For a consumer that would have to be compared with the difference in price.
We run combustor testing 200+ days a year. We torture them. The combustors we use provide reduced emissions over a greater period of time. This translates to a longer life of clean burning.
This will wrap up my sharing on this topic.
