A Buddy Heater’s Built-in Regulator

According to Mr. Heater, there is a built-in regulator in all the company's portable heaters.

Any appliance using propane needs a regulator. You'll find it on the tank next to a supply line, while a Buddy system's regulator is on the heater itself.

Using a detachable regulator will only over-regulate the gas supply. Over-regulation during high-pressure gas flow can squeeze the rubber. It pulls oils and plasticizers, which are contaminants.

The built-in 10-foot buddy hose has no plasticizers or oil that can pass out during high-pressure propane flows. Some other hoses need filters because they contain oils and plasticizers.

Is There A Difference Between A Regulator and A Filter?

For the Buddy heater, the built-in regulator maintains the propane gas flow. If you are using gas tanks, other than the one-pound cylinder, a hose assembly is required, which serves as a fuel filter.

Safety Tips For Using Buddy Heaters

According to Consumer Reports, portable heaters are responsible for an average of 1,700 house fires annually. Fires by portable heaters result in about 80 deaths per year.

About 50% of home heating fires occur during December, January, and February. The fires happen because the portable heaters are near curtains, upholstered furniture, and bedding.

The National Fire Protection Agency and the Association of Home Appliance Manufacturers offer these safety tips:

  1. Set up the portable heater on a hard, non-flammable surface.
  2. Keep the portable heater at least three feet away from flammable and combustible materials like furniture and curtains.
  3. Children and pets should maintain three feet of distance from the heater. You should never place or leave a portable heater in a child's room.
  4. Never use a portable heater in a garage or workshop where paint, matches, and gas cans are stored.
  5. Turn off the heater when leaving the room.

Buddy Heater Safety Features

Mr. Heater Buddy portable heaters are equipped with specific safety features such as the following:

  1. Safety tip-over switch - This is a small device inside the heater that turns off the heater when the unit tips more than a certain number of degrees from the proper upright position.
  2. High limit safety shut-off - This is another small device that will turn the heater off if the internal temperatures of the device rise above a specific level.
  3. Oxygen Depletion Sensor (ODS) - As a detection system, it accounts for low oxygen levels and turns the portable heater off.
  4. Altitudes over 7,000 feet above sea level will auto-shut the portable heater.

Mr. Heater certifies its products for indoor use. Canada and the state of Massachusetts do not allow the use of propane heaters indoors. That's the reason why there are different models for these locations.
