Gas Logs and Replacement Logs

Customer Q&A with Product Specialists

Charlotte from longview asked:

Which 42-inch gas log set puts out the most heat?

Logs sold without a burner do not produce heat on their own, since heat output comes from the burner. For maximum heat, choose a complete burner and log set with a high BTU rating. Among our standard single-sided 42-inch vented sets, the highest rating is 130,000 BTUs on natural gas. Several Real Fyre 42-inch sets share this rating, including the Real Fyre 42 Inch Rustic Oak Vented Natural Gas Log Set - Match Light, which ships the same business day and requires a firebox at least 48 inches wide at the front. Vented sets are designed mainly for ambiance rather than primary heat. If heating the room is your main goal, a vent-free gas log set or gas fireplace insert will be a better fit. Vent-free logs can only be installed in a masonry fireplace or a factory-built wood-burning fireplace listed to accept them, so confirm your fireplace type first. Our Virtual Gas Log Set Assistant shows every set that fits your firebox measurements and fuel type.

Kathy A. from Woodstock, CT asked:

I have a gas log set that is no longer sold. The logs need replacing due to the age of the set, but the burner works like it always has, perfectly. Can I buy replacement logs of another brand and put them on my current burner?

Typically, no. The logs and burner are matched to work as a pair. This is especially true when using a vent-free log set.

Peter S. from 92037 asked:

Do some logs put out more heat than others?

Yes, different gas log sets with different burners have varying levels of BTU (heat) output.
