Item Information

If you are looking to turn your garage or barn into a work space you can use all year-round, you will have to find a safe quiet and reliable heat source. This Mr. Heater 50,000 BTU Natural Gas Unit Heater is the way to go. It uses a built-in electric high velocity fan to pull cool air into the rear of the heater, across a heat exchanger, then forcing warm air into the surrounding areas.

  • Requires 115V AC power and can be vented vertically or horizontally - please check local codes and restrictions
  • With a mounting clearance of only 1 inch, the supplied brackets, external access to power, and thermostat connections - installation is a cinch
  • Durable Spark ignition and robust factory standard self-diagnostic control module
  • 3 year factory warranty on all parts and burners and a 10 year warranty on any defects in the heat exchanger

Note: This product may require up to 2 additional days for order processing prior to shipping

Rated 3 out of 5 by from Furnace works great Very happy easy install. For our needs we needed to heat (to around 40°) a insulated pole barn 30 x 40 with 14' to the bottom of the rafters. We do have a wood stove and last year we also used ventless propane heaters. The problem was burning the propane heaters with no ventilation cause a lot of condensation to the point where it would rain in the building. We expect the furnace will heat with dry air eliminating the condensation issues.

In the specs it states the heater must be 8 feet from the bottom of the heater to the floor.  I wanted to put it 5 feet off the floor.  It seems if the unit can be mounted inches from the ceiling above it, 5 feet below or even less would work.

Asked by: Ritzen
We have the spec so a person does not bump into the bottom of the heater. check your local regulations . Mr Heater

I want to sit this heater near the floor instead of hanging from the ceiling. How high off the floor is a safe distance?

Asked by: Lois Lane
This heater is designed to be hung securely from above to accommodate exhaust and best use of the blower. The installation is code and regulation driven and you can be asked to remove it by inspectors. You may want to consider another kind of heater purposed for near the floor. Rich Mr Heater
