Review: Works great - This is amazing. Wish they would stop raising the price. Would be nice to get another one. Everything works great on it. Auto shutter-off works, heat feels great, airflow is perfect. Looks good and is stable hanging up.
Review: All right, this is my yearly update for my Mr Heater. - Update April 19, 2026 Alright guys, forgot to update you all last fall. I got frustrated last fall when I hit the switch and got the clicking to fire up the gas and nothing.. Turns out there was a little piece of fuzz or spiderweb plugging up the vacuum line that that needs to be clear to engage the solenoid that opens the gas valve. Cleared out the fuzz from the line and BOOM, it fired right up. So mechanically it was fine, just a little cleaning required. Still love this heater, it’s April in upstate NY and it’s snowing..So had to fire it up to work on my lawn tractor (a different issue, always something required to keep life moving forwards) and it reminded me I hadn’t posted an update. I still highly recommend this heater.. Update Feb 9. 2024 Still going strong. Absolutely NO issues.. Update: October 17, 2023 I flipped the heater on today after leaving it off since sometime in April.. Its been in the low 50's so I just wanted to take the chill out of the garage and sort out my tools for a fall project. The unit fired right up, warmed up the garage, no issues, just did its job. This unit has been very reliable for me, and I continue to recommend this heater for a garage. ------------------------------------------- I bought this heater in September of 2019 when I retired. I live in western NY where the winters are long, dark and cold. Since the wife doesn't want to snowbird in the south, I figured I better heat the garage, so I had a place work on projects. If you can run some natural gas lines and stick a vent through the roof, you will love this heater. I stuck a cheap thermostat on it from one of the big box stores, a separate house switch on it to flip it off for the summer months. I have had NO problems with it. It runs for 6 months during the cold months, then I flip it off at the end of April, when October comes, I flip it back on and it fires right up. It doesn't make any vibrating noise like some have said, vents out the garage roof using the double wall vent duct with a hat to keep the snow out. I insulated my garage walls and ceiling with standard R19 from HD, and drywalled it as well. My garage is 24' x 24' x 10' with concrete floor. This unit heats it with no problem. I should have installed one years ago. Also, I did not use an isolation relay to isolate the unit that protects the house wiring from "a pulse" from the unit when the solenoid kicks on and I have experienced no issues with the unit interfering with the house electric. I have broadband internet, smart switches, smart lights, Alexa, etc.. and have experienced no issues. If you're like me, live in the north and have some DIY skills and are sitting on the fence, just pull the trigger and buy it. You'll get a whole new play area for the winter months. :-)

### ⭐⭐⭐⭐⭐ !!!! REALLY GREAT HEATER !!!!
*by M***6 on January 20, 2020*

So worth the price, and very easy to install. Yeah the exhaust duct work costs almost as much as the unit itself. But We'll Worth It!!! Heats up the Garage almost instantly, my Garage is a 1 1/2 car garage. It's 12°outside currently in Buffalo NY. 01/20/2020. Turned the heater on and it was warm in 7 minutes, about 60°. The fan is quiet, don't listen to the other reviews. Not saying that their unit was loud but maybe they had something wrong with their fan?? My garage is a Gym and to work out in the winter it's great to have the Garage Heated. This unit goes ABOVE and BEYOND my EXPECTATIONS. Im VERY PLEASED with the performance, the ONLY advice i can give is that THE DIRECTIONS SAY TO pitch the duct work UP a quarter inch per foot. DO NOT pitch it UPWARD!! the CONDENSATION will run right into the heater. Their is a Fan their inside the unit that will get wet and ruined. I had to fix this because for 1 i could not find a 4" piece that's shown in the instructions that had that DRIP HOLE where you have to attach a drip hose to. I don't know why you would want a hose hanging down from your exhaust anyway with nowhere to drain it to... "PRO TIP" So angle the duct work downward and this way the sweat/ Condensation will run outside - out of the exhaust. If not you're going to have sweat and condensation running towards the heater ruining and rusting the inside of the heater. That's the only thing that I seen in the instructions that were horribly wrong. Everything else was a breeze. The gas line, the electrical, the thermostat simple work. I am installing a smart thermostat so I can control it from my phone, So when I wanna go out there and work out I will turn to thermos son 5 minutes before I go out their. Thank you, hope this review helps someone.
