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 molds and bacteria. An oxygen depletion sensor ods on unvented gas heaters and fireplaces shuts off the gas flow if the oxygen level drops below 18 an indicator that not enough fresh air is getting into the house but the ods does not detect carbon monoxide or other hazardous emissions.

Yes carbon monoxide inside the home is certainly a danger and that s the best reason to get rid of unvented gas space heaters. Ventless is the key word behind the moisture problem in this room. The absence of a venting mechanism results in indoor moisture accumulation.

Gas wall heaters whether vented or unvented can supply enough heat to warm a small or medium sized room and they can operate with propane or natural gas. This greatly reduces the fumes. Carbon monoxide results from incomplete combustion of natural gas.

As the ventless gas fireplace produces heat it also generates a considerable amount of moisture. When one isn t working properly the.
