The Integrated Regulator In A Buddy Heater

All of the portable heaters made by the company, according to Mr. Heater, include a built-in regulator.

A regulator is required for any propane-using appliance. The Buddy system’s regulator is on the heater itself, whereas the tank-mounted system’s is located adjacent to a supply line.

The gas supply will only be excessively regulated if a detachable regulator is used. The rubber may be compressed by over-regulation during high-pressure gas flow. Oils and plasticizers, which are pollutants, are drawn out.

There are no plasticizers or oils in the built-in 10-foot buddy hose that could leak during high-pressure propane flows. Because they include oils and plasticizers, several other hoses require filters.

Is There A Distinction Between A Filter And A Regulator?

The built-in regulator regulates the propane gas flow for the Buddy heater. You need a hose assembly that serves as a fuel filter if you’re using gas tanks other than the one-pound cylinder.
