Exactly what I needed to keep working through the winter! *by on Reviewed in the United States December 3, 2024* 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: 28FGarage Inside temp when heater was turned on: 40F30 minutes after heater on inside temp: 53F1 hour after heater on inside temp: 59F2 hours after heater on inside temp: 65FThe 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 Amazon 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. ### ⭐⭐⭐⭐⭐ Works great *by on Reviewed in the United States July 11, 2026* 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. ### ⭐⭐⭐⭐⭐ !!!! REALLY GREAT HEATER !!!! *by on Reviewed in the United States 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 12Β°outside currently in Buffalo NY. 01/20/2020. Turned the heater on and it was warm in 7 minutes, about 60Β°. 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. ## Frequently Bought Together - Mr. Heater F260550 Big Maxx MHU50NG Natural Gas Unit Heater,Black - Mr. Heater F210359 Thermostat for Heater,Tan,Small - Mr. Heater F271239 One-Stop Universal Gas-Appliance Hook-Up Kit,Small --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/12954544-mr-heater-50-000-btu-forced-air-unit-heater-propane](https://www.desertcart.co.uk/products/12954544-mr-heater-50-000-btu-forced-air-unit-heater-propane) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-08-14*
