Single Burn-Rate Wood Stoves New Again -Mar 8/2016 Single burn-rate wood stoves have been around since the very first crude wood-burning appliances were created. Basically, they’re wood stoves, inserts or fireplaces in which the incoming combustion air cannot be adjusted, unlike the majority of today’s wood stoves. This results in a burn rate that cannot be dampered or controlled for long burn times. Proponents claim that since these units burn very hot, they produce very low emissions, even with a large firebox. Thousands of these single burn-rate stoves have been sold over many years. Most are less expensive, simple, price-point models used as shop, garage and barn heaters. Until Dec. 31, 2015, the EPA did not regulate single-rate models. But with EPA’s new NSPS, single burn-rate stoves must now meet the same emissions requirements as adjustable burn-rate models – 4.5 gph now and 2.5 or 2.0 gph in 2020.
