Ventless gas logs
Ventless gas logs are a great option when looking for a secondary heat source in your home, they operate at 99.9% efficiency and will quickly heat up to 1300 square feet. The range of BTU'S will vary due to size, style and whether you are heating with natural gas or propane. With a ventless gas log system you have the best of both worlds, heat when you want or need it, or open your damper to release the heat when you don't. Ventless gas logs are designed to be used 4 to 6 hours a day, as long as you are within that range of time, moisture will not be an issue in your home.
