Best ventless propane heater with thermostat You'll be hard-pressed to find a more powerful, reliable unit on the market. The Rinnai ventless propane heater safely offers unmatched heating ability.

When properly maintained and adjusted, gas heaters produce low amounts of carbon monoxide. One cause of carbon monoxide poisoning from unvented heaters– incomplete combustion caused by lack of air–has been virtually eliminated in newer heaters by use of Oxygen Depletion Sensors (ODS).

Blue-flame heaters are ideal for insulated spaces, while infrared heaters work best in uninsulated areas. It's important to keep in mind that vent-free heaters should only be used as supplemental sources of heat. This means only operating the heater when you're in the room and turning it off when you leave.

If you are using a vent-free propane space heater, using it while sleeping puts you in danger of carbon monoxide (CO) poisoning. Because carbon monoxide is odorless, you can take in a dangerous and even lethal amount of it when you're asleep before the CO detector near your bedroom goes off.
