Here is a NON-scientific testing of the two densified wood firelogs. Although, Non-scienfific it may be respresentative of how "Joe Homeowner" may test the effectiveness of the products. With this said, you should perform your own tests in your own burning device because results will vary. This way you can make an informed purchasing decision based on your own needs and desired outcome.
For this test we took a 4, 5lb Hearthwise Premium Pellet Firelogs with a half pound fire starter on the right side. 4, 3.5lb Smartlogs with a half pound fire starter on the left side.
One half hour after ignition. Smartlogs are starting to "accordian". Hearthwise Premium Pellet Firelogs remain whole.
One hour after ignition. Smartlogs have broken in half and have continued to "accordian". The Hearthwise Premium Pellet Firelog remain whole.
Two hours after ignition. Smartlogs are pretty much done while the Hearthwise Premium Pellet Firelogs are still going strong.
Two and one half hours after ignition the Smartlog is done heating while the Hearthwise Premium Pellet Firelogs are still heating.
Three hours after ignition the Hearthwise Premium Firelogs are still heating (even though there is little flame, this stage resembles coal burning). At this point you can break down the logs to form a coal base and add logs to extend the fire. For this test we will break down the logs.
Four hours after ignition the Hearthwise Premium Firelogs are still heating.
Five hours after ignition the Hearthwise Premium Firelogs are still heating.
