Furthermore, do ventless heaters produce carbon monoxide? A good gas heater that is well maintained will produce very little, if any, CO - carbon monoxide.
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 ventless fireplaces cause moisture?
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.
Do natural gas heaters produce 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.
Do gas heaters cause humidity?
The answer is that running a gas furnace can lead to lower humidity inside a house. The furnace's burners don't dry out the air, however.
Does a gas fireplace give off moisture?
Gas fireplaces make the air dry and create moisture–that is the answer to the question. Gas fireplaces create moisture in the air, while simultaneously drying the air out.
Which is better vented or ventless gas fireplace?
Ventless fireplaces are more energy efficient than vented fireplaces because no heat escapes up the flue, so you'll save money on gas utility bills. A vented gas fireplace uses more gas to create the same level of warmth because some of its heat escapes through the flue.
How do I stop condensation in my gas heater?
If there are no heater-venting problems, then the condensation is probably caused by excessive indoor relative humidity from other sources. If a humidifier is being used, turn it off. Bathrooms, kitchen and laundry should be equipped with vent fans that can expel excess moisture to the outside.
Do gas heaters remove humidity?
Because the furnace continuously uses air to burn, it will also draw in cold, dry air from outdoors, which in turn lowers your house's humidity.
Does the heater make the air dry?

Do heaters increase humidity?
Heaters do not take moisture out of the air itself. However, once the air is warmed past a certain point, it can absorb a lot of moisture. It then draws moisture away from your body, making your skin feel much drier. Essentially, heaters cause much lower levels of relative humidity.
Will a heater dry out damp walls?
Yes, a space heater or centralized heater can help to dry out damp walls. You can also use a dehumidifier for this task as well. However, you'll want to use caution and ensure that the building materials are not sensitive to heat.
Is natural gas ventless?
Natural gas is 80 percent water vapor, and when that vapor doesn’t have a proper escape route, it creates an indoor environment akin to a tropical rainforest and extends a direct invitation to dangerous mold s and bacteria. The heater may be called ventless, but that only ...

Are Ventless Propane Heaters Safe?
Ventless propane heaters are not safe because they dissipate all the combustion products into the room. The combustion of propane produces several products, including carbon dioxide, carbon monoxide, water vapor, and nitrogen dioxide.
How do Ventless Gas Heaters Work?
Ventless gas heaters produce heat energy by burning gas and oxygen. They are portable heating devices that are not vented to the outside. Venting is vital for heating devices because it helps provide an escape route for all the combustion products.
