The Mr. Heater Portable Buddy® Heater, model MH9BX, is a popular choice for portable heating solutions. It is designed to run on propane gas and can emit 4,000 or 9,000 BTU per hour, providing heat for up to 225 square feet. When using a 1 lb. propane cylinder, the run time varies depending on the heat setting, with approximately 3 hours on high and 6 hours on low.
Understanding Propane Consumption Rates
The fuel consumption rate of the Mr. Heater Portable Buddy® Heater varies with the heat setting. At 4,000 BTU, the heater consumes 0.044 gallons of propane per hour, while at 9,000 BTU, it consumes 0.099 gallons per hour. These figures can help users calculate their propane usage and costs more accurately.
| Heat Setting | Propane Consumption Rate |
|---|---|
| 4,000 BTU | 0.044 gallons per hour |
| 9,000 BTU | 0.099 gallons per hour |
To determine the run time of a 1 lb. propane cylinder, we can use the following calculations:
1 lb. propane cylinder = 0.434 gallons of propane
* At 4,000 BTU (0.044 gallons per hour): 0.434 gallons / 0.044 gallons per hour = 9.86 hours
* At 9,000 BTU (0.099 gallons per hour): 0.434 gallons / 0.099 gallons per hour = 4.38 hours
Therefore, the approximate run time of a 1 lb. propane cylinder on the Mr. Heater Portable Buddy® Heater is:
* 4,000 BTU (low): 9.86 hours
* 9,000 BTU (high): 4.38 hours
Factors Affecting Propane Consumption
Several factors can influence the actual run time of the Mr. Heater Portable Buddy® Heater when using a 1 lb. propane cylinder:
- Ambient Temperature: Colder temperatures can increase the propane consumption rate, as the heater works harder to maintain the desired temperature.
- Insulation and Airflow: The level of insulation and airflow in the space being heated can affect the heater’s efficiency and, consequently, the propane consumption.
- Usage Patterns: Frequent on/off cycling or intermittent use can impact the overall propane consumption compared to continuous, steady-state operation.
- Heater Condition: Proper maintenance and cleaning of the heater can help ensure optimal performance and fuel efficiency.
