Difference Between Vented And Vent Free Gas Logs

They put out a constant rate of heat.

Difference between vented and vent free gas logs.

Because they use less fuel and burn more efficiently the flame is not as large as a vented gas log set. Vented and ventless gas logs are a little different. Each type of fireplace requires its own type of gas logs to function safely and correctly. Innovations in technology are changing that.

Vented gas logs burn like a real wood fire with a yellow flame that produces smoke. The reason for this is that they do not burn the gas cleanly and create exhaust that is very similar. Ventless vent free gas logs burn cleanly with a lower flame that does not smoke. The flame is much more attractive than it was 20 years ago.

While they will emit some heat they do not discharge as much heat as a built in gas fireplace or gas insert. Yes ventless gas logs heat more effectively than vented logs because there s no chimney flue for the heat to escape through. Gas logs are usually more for looks and aesthetics than for warmth. Vented gas logs offer a full authentic looking flame presentation with plenty of ambiance while ventless gas logs provide a reliable and efficient heating source.

Vented gas logs are designed to produce a beautiful roaring fire but it comes at a cost of fuel. Vent free fireplaces use no vents and in certain existing homes they re the only gas option if new ducting can t be supported by the home s infrastructure. Vent free gas logs burn less fuel than vented gas logs and are 99 9 efficient. Vented gas logs require a fully functional wood burning fireplace and must be burned with the damper.

Vented gas logs vent up your existing chimney while vent free gas logs vent all of the heat and exhaust into the house they do not require a chimney or flue. Vented gas logs produce carbon monoxide emissions so your fireplace must have a chimney or flue. Vented gas log sets are also less efficient since some of the heat that s produced escapes through the chimney. Some of the benefits of vent free fireplaces include.

Ventless logs do not put off these emissions so no chimney or flue is needed and the heat is more likely to stay in your space. They must be burned in a wood burning fireplace with the damper open so smoke goes up the flue along with most of the heat.
