Mr. Heater

Mr. Heater heaters are for homeowners and contractors heating a garage, workshop, or construction work area. The range includes propane and kerosene forced-air heaters, portable radiant heaters, and propane connection hardware, so you can match the heat and the hookup to the job.

Mr. Heater is Enerco Group Inc.’s heating-products brand. Enerco designs and manufactures consumer, heavy-duty commercial, and construction heating products. The brand previously operated as Mr. Heat-IR.

Match the heat to the work

Forced air moves warmed air through the work area, which helps when you’re moving between tasks. Mr. Heater offers propane and kerosene versions. Choose around the fuel you can handle and replenish, then check the particular heater’s electrical requirements. Forced-air electric heaters are another Mr. Heater option when the available electrical supply meets the model’s requirements.

For work concentrated at a bench, consider Mr. Heater’s portable radiant heaters. Radiant heat warms people and objects in its path, so placement matters. Keep the heater’s required clearances open around the work area.

Floor area multiplied by 40 gives a starting estimate of required BTUs. Ceiling height, building layout, and insulation affect the result. A tall, poorly insulated shop needs a different calculation from a tight room with the same floor area. Size for those conditions.

Indoor use and setup

Buddy heaters are certified for indoor use, with the individual model’s manual governing the permitted setting and ventilation.

For a Garage/Shop heater, follow the individual model’s installation and ventilation instructions because residential and construction indoor-use standards differ, and commercial indoor use involves heavily ventilated spaces.

Before lighting a propane heater, establish the required ventilation and clearances, check the fuel connection as instructed, and follow the model’s lighting sequence. Controls and starting procedures depend on the heater. Use the manual that matches its model and production version.

Fuel planning belongs in the setup too. Runtime depends on the heater, heat setting, and fuel supply. Compare the model’s stated runtime at the setting you expect to use.

Get the propane connection right

Mr. Heater offers hoses, fittings, and regulators with different lengths and connections. Match the appliance connection and pressure arrangement before choosing the length. Regulator placement matters as much as whether the fittings screw together. Follow the accessory package’s stated application and the heater’s connection instructions.

High-pressure propane can draw oils and plasticizers out of some rubber hose materials. Contaminants carried into a heater can accumulate and cause gas-flow trouble. Use the hose-and-filter combination specified for the setup. When gas-pressure testing is needed, use a gas-company professional or an HVAC-certified person.

Parts and warranty

The heater’s serial number helps identify its production-year parts schematic. Match replacement parts to that drawing, especially when similar-looking heaters have different production versions.

Mr. Heater’s general limited warranty provides one year of coverage against defects in materials and workmanship through product or parts replacement; Unit Heaters carry three years. Coverage excludes servicing and installation labor.

Frequently Asked Questions

How do you vent a Mr. Buddy heater?

A Buddy heater needs the fresh-air ventilation specified in its manual. The general ventilation guideline is one square inch per 1,000 BTUs, but your particular heater’s instructions determine the setup. Indoor-use certification doesn’t remove that requirement.

How do you use a Mr. Heater propane heater?

Set up ventilation, clearances, and the fuel connection according to your heater’s manual before following its lighting sequence. The correct manual matters because starting procedures vary. If you’re using a Buddy heater, it’s for heat only: cooking or warming food isn’t safe, and unapproved attachments are prohibited.

Do you need a filter for a Mr. Buddy heater?

Whether your Buddy heater needs a filter depends on the hose and pressure setup, so match the hose-and-filter combination to the heater’s instructions. The filter traps contaminants that can accumulate inside the heater and restrict gas flow. If your setup uses a filter, start each heating season with a new one; a filled filter can let contaminants pass through.

How do you find the right parts for a Mr. Heater?

Your heater’s serial number helps identify the parts schematic for its production year. Match the replacement part to that drawing, rather than going by appearance. The serial number may also be needed to find the correct manual.
