Ventless gas heaters are room-heating furnaces that do not vent air to the outside of the house. Instead, the oxygen that is needed to fuel the combustion process for heat is taken from the air inside of the room in which the unit is placed, and the resulting heat is vented back out directly from the unit.
Are ventless heaters any good?

In addition to carbon monoxide, ventless fireplaces also produce a high levels of water vapor. The increased level of water vapor in the home will increase humidity, increasing the risk of mold growth.
Which is safer vented or ventless gas logs?

Do gas heaters cause condensation?
Gas heaters cause condensation in winter “An unflued gas heater produces lots of C02, together with all the water vapour in the air, condenses on the wall, and then the C02 feeds the mould. “Hot air holds a lot of moisture, and at night when the air cools down, the moisture condenses on the walls.
How much moisture does a ventless heater produce?
However, consumers need to know that the combustion process produces water. A 20,000 BTU vent free heater will produce about ¼ gallon of water into a living area each hour.
Do gas heaters make moisture?
Yes, the combustion process produces a lot of water vapor, but that water vapor doesn’t get into the house. If you have unvented gas heaters, however, you do get that water vapor, and it can be a problem. That takes you in the opposite direction, though. It humidifies the house; it doesn’t dry it out.
Can a ventless fireplace make you sick?
