## Overview

The Mr. Heater ceiling-mounted forced air propane unit delivers a robust 50,000 BTUs to efficiently heat up to 1,250 sq ft, transforming garages, barns, and workshops into comfortable, year-round workspaces. Compatible with both standard 24-volt and Wi-Fi enabled thermostats, it features a low-profile design requiring minimal clearance, plus advanced safety sensors for reliable, worry-free operation. Backed by a 3-year parts warranty and 10-year heat exchanger guarantee, it’s the smart, affordable choice for professionals who demand warmth and efficiency.

## Description

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 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. These heaters only require 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. With the Durable Spark ignition and robust factory standard self-diagnostic control module, we can offer a 3 year factory warranty on all parts and burners and a 10 year warranty on any defects in the heat exchanger. This heater offers the operating versatility and safety that you have come to expect from Mr. Heater.

Review: Affordable and powerful. Exactly what I needed to keep working through the winter! - Hopefully this review is useful for other, it was hard to find real examples of use like this to get an idea of how well this unit will heat my space. I am heating a 21'x33' garage with an 11' ceiling. Walls are insulated at about an R15 but ceiling with unfinished attic above it is not insulated. Overhead garage door is insulated. Here's the data: Outside temp: 28F Garage Inside temp when heater was turned on: 40F 30 minutes after heater on inside temp: 53F 1 hour after heater on inside temp: 59F 2 hours after heater on inside temp: 65F The heater was able to get the temp inside the garage up to 70F after about 2.5 hours after not being used all day with an outside temp of 20F the other day as well and it keeps things very nice and comfortable. I cannot speak to reliability as I just purchased, but installation was easy (check Menards for their category 3 horizontal venting kit as it is half the price of the manufacturers kit), and the price was insanely good compared to all of the other options. I was quoted $3500 installed for other brand units from several different local HVAC companies and I was out the door installed (had a local company do part of the install) for around $900 total. I put the unit up and ran electrical but had the installer do the gas line and vent kit install. Since the unit was so inexpensive, I did add the 4 year desertcart protection plan. Hopefully it lasts a long time but if it doesn't, at least it will be easy and free to replace. All in all a good value and it gets the job done.
Review: easily keeps three car garage in Minnesota warm - Just what you would expect from Mr Heater. Was easy to install and has been heating my Minnesota three car garage for about three years now without any issues. I keep it at 50 degrees most of the time and the gas bill only went up like $7 a month. Highly recommend it.

### ⭐⭐⭐⭐⭐ Game changer for our garage!
*by A***N on August 31, 2025*

A great heater! Good install instructions. Make sure you read them and follow them! Lots of good guidelines. Heater itself is heavy but seems to be built well. I added a nest thermostat. Easy to wire a power cord on and easy to get exhaust and gas line hooked up. This is going to be a game changer for when I get back from plowing in the winter! I have natural gas and it came set for that. They do include the kit to switch to LP. I’ve tested this a few times when it’s been cooler recently and the garage heated up extremely fast! FYI I did a lot of research before install, but as I said the instructions are laid out well.
