Does a Big Buddy Heater Need a Propane Regulator?

The Big Buddy Heater is a popular portable propane heater that offers versatility in its usage and connection options. When it comes to the question of whether a Big Buddy Heater needs a propane regulator, the answer is not a straightforward yes or no, as it depends on the specific model and the type of propane source being used.

Big Buddy Heater Models and Regulator Requirements

The Big Buddy Heater comes in various models, each with its own unique features and specifications. The key factor that determines the need for a propane regulator is the BTU (British Thermal Unit) rating of the heater.

18,000 BTU Big Buddy Heater Models

The Big Buddy Heater models rated at 18,000 BTU are equipped with a Quick Disconnect (QD) port, which allows them to accept low-pressure gas (regulated) directly. This QD port enables the use of a hose assembly, such as the F271803, which eliminates the need for a separate regulator. The hose assembly provides a “one size fits all” solution for connecting the 18,000 BTU Big Buddy Heater to various propane sources.

Buddy and Little Buddy Heater Models

The Buddy and Little Buddy Heater models, which are rated at lower BTU levels, do not have the QD port feature. These models typically require the use of a separate propane regulator when connecting to high-pressure gas sources, such as a 20-pound propane tank.

Filters and High-Pressure Gas Sources

While a regulator may not be strictly necessary for the 18,000 BTU Big Buddy Heater models, the use of a filter is highly recommended when connecting the heater to high-pressure gas sources. This is because high-pressure gas can introduce contaminants that can potentially damage the internal components of the heater.

The filter should be changed periodically, typically every year or two, depending on the frequency of use and the quality of the propane source.

Direct Connection to Propane Tank

When connecting the Big Buddy Heater directly to a propane tank without an extension hose, a regulator is not required. However, even in this scenario, the use of a filter is still recommended to ensure the longevity and proper functioning of the heater.

DIY Tips for Connecting the Big Buddy Heater

Secure Connection: When connecting the Big Buddy Heater directly to a propane tank, ensure that the connection is secure and that the tank’s safety valve is properly engaged.
Hose Assembly Connection: When using a hose assembly, make sure to force the connection into the tank’s valve to open the hidden safety valve. This may require additional turns or the use of a wrench.
Regulator and Filter Maintenance: If using a regulator and filter, regularly inspect and replace the filter as recommended by the manufacturer, typically every year or two, depending on usage.
