Question: We are getting conflicting information about whether the solid ceramic logs are better than the newer ceramic fiber logs. Specifically, we are concerned about the durability of the ceramic fiber logs and how they compare with the solid ceramic logs. We would also like any other information you deem significant in comparing the two types of logs. We will be using ventfree logs in an existing masonry fireplace to heat a finished basement area. Thank you in advance for your assistance. Answer: Neither is really better. They are different in some ways. With fiber logs, the flams often actually hits upon the log, making it glow. In the case of solid logs (in vent-free products) the flame is designed not to touch the log...if it did the log set would produce soot. The solid logs often have more detailing because they are hand-painted rather than just formed. As far as longevity, the solid logs will probably outlast the fiber ones, but we've had lots of fiber logs in the fiel for 3 or 4 years with little or no problems. Replacement logs are available at a fairly low cost. Remember, vent-free products are for attended space heating only...to be used a couple of hours a day. These products are not for full-time heat.
