It all depends on what kind of heater you have. Some people have had great experiences using vented propane wall heaters. The vented propane wall heaters allow the air to escape where as the unvented wall heaters will keep the moisture in the mobile home.
The other thing to take into consideration is how long you would keep the propane heater running. The moisture will only build up in the mobile home if you keep the propane heater running all the time. It is probably best to get a timer switch that will monitor the length of usage of the wall heater.
If you do have the heater on 24/7 make sure you take precautions and safe measurements by installing a CO detector and gas detector. Having carbon monoxide poisoning is no laughing matter.
Carbon monoxide detectors are very important to keep in your house, mobile home and office. Any building that has gas running through it should have a Carbon monoxide detector. This detector can show early signs of gas leaks and avoid carbon monoxide poisoning.
CO is one of the causes of accidental poisoning deaths in America. People do not take enough precautions when installing any type of gas instruments.
