| Burning propane doesn't produce the poisonous exhaust that diesel and gasoline does, and therefor can //sort of// safely be run indoors without ventilating the exhaust products. There are a couple of things to remember about this method though: | Note: these are called //non-ventilated// heaters because there is no external exhaust for the heater. |
| * Burning propane **generates water vapor** which will increase the humidity in your vehicle. You may require additional ventilation or [[hvac:dehumidifier|dehumidification]]. | |
| * Burning propane **generates carbon dioxide.** Even clean-burning, low CO2 emission heaters **generate much more CO in low oxygen levels**. This is the reason you are supposed to ventilate. | * **Ventilation of the heated space is still required**. (ie the heater isn't vented but your living space must be) |
| | * the primary outputs of propane combustion/catalysis are **water vapor** and **CO2**. This means running an unvented propane heater will increase the humidity in your vehicle. You may require additional ventilation or [[hvac:dehumidifier|dehumidification]] unless you are in an area with very low humidity. |
| | * **if O2 levels are too low** (due to insufficient ventilation) the reaction gives off **increasingly-deadly amounts of CO**((carbon *mon*oxide)). This is the same culprit as deaths from folks running generators indoors, vehicles in the garage, etc. So we keep O2 levels normal by ventilating the space. |
| * Any forced air heater will require electrical power to run the fan. | * Any forced air heater will require electrical power to run the fan. |

| Tip: you can turn the Buddy down //below// the LOW setting by depressing the gas knob like you are turning it off, then //slowly// easing the setting back to the desired level. The flames will "flutter" a bit if set too low -- increase slightly from that point. Check your CO detector to make sure your CO output isn't increased. | Tip: you can turn the Buddy down //below// the LOW setting by depressing the gas knob like you are turning it off, then //slowly// easing the setting back to the desired level.
