Qmark MUH072 Self-Contained Unit Heater for Factories Warehouses, Garages, Loading Docks, and Industrial Settings, 7500 Watt, 240 Volt, Beige

Great heater easy to install. Have hooked up on job site in past. Knew when it was time for me to buy one this would be the brand I would buy. Fairly quiet for the cfm. Love this heater hope it last years and years.

This little heater is great for my 2 car insulated garage. Hooked up a Wi-Fi tstat to it and works like a charm. It’s quiet as well.

I did a great deal of investigating before this purchase. There are so many heaters on the market to pick from.I was able to see this one in action at a work site and was impressed by the amount of heat it was throwing out.Ordered my heater and was installing it three day later. I use 8ga braided cable, 40amp double pole breaker andwall mounted 24 volt thermostat. After finishing up install, verifying termination and voltages I fired up unit and letit run for about ten minutes. Cleaned up my mess from installed and wanted to cycle heater one more time beforeI called it a night. Turned heater back for the second time when the blower motor came on it was a lot louder than thefirst time I ran it and within 5 seconds I heard a pop sound followed by white smoke. Not what i was expecting from aquality heater. Contacted Amazon they were great like always was told contact manufacture direct. I spoke to Darrenfrom customer support and he was great. He knew right away I had a bad blower motor and said I'll have onesent to you in a few days. Three days later motor was at the house took me all of ten minutes to change out. So farheater is working great I will up date after more use.

I purchased this heater to replace the identical system. I've had the other for over 15 years, heating my workshop. They are easy to install and made in the USA.

Very nice heater, installed it in my 24 x24 shop which has concrete block walls

incredible buy

These heaters are well built or were. I maintained a few for years in industrial environments before I retired.Here is why I gave a 1 star review. I found that it is impossible to get parts or even a return call from the manufacturer. When you contact the manufacture there is no one available who will sell you parts through the manufactures website or at the provided phone number on the parts list. I was unable to raise a human and no one responsed to the messages left on the message machine I did reach or messages sent by the messaging system at their website. I believe it is good to know this before you purchase it. It was not what I was expecting. I bought a MUH072 on line. I purchased this to put into a remote building that would be inaccessibly in the winter. I needed a heater that could be inspected each summer, maintained as necessary, then expected to make it through the winter keeping a building from freezing up unattended. There is back up heat there for intermittent power outages, but only a limited supply of fuel, not enough to run the entire winter.I've had good luck with these heaters lasting in harsh industrial environments, better than most brands. The price didn't seem to bad either.However it is crucial that I can buy parts to maintain it. Although it comes with everything that would lead you to believe you can buy parts, when you attempt to contact the manufacturer to actually buy them you reach a dead end.My heater arrived with a bent fan blade which I straightened. Could have been damaged in shipping or just not right when assembled. This place is remote so there was no choice but to fix it and put it on line. I didn't have a week or two to wait for another one to arrive and possibly be in similar condition. Winter had started early.I am now trying to replace the fan blade. I want the fan blade to be in balance dynamically when it runs and the best way is to put on a new one that hasn't ever been bent. I am trying to purchase a new one. The blades for this list for about $70 or double what a generic blade from Grainger this size would be. I'm not trying to warranty it even though it is within the warranty period. I need to get this done as winter will be here again. I don't want a generic blade because the the actual air flow is still a best guess. I want to be sure that the air flow over the elements is as designed to insure max life of the unit. I want an OEM fan blade even though they are extremely over priced. Even before shipping.I don't need another bent one, have one. This sort of fan blade are delicate when out of the heater. They have to be stored right and packaged correctly to withstand shipping. Needing one that hasn't been abused I turned to the manufacturer. I have been unable to get any response from the manufacturer when I contact them about purchasing one , not an email back from their message system or a return call from the message I left with technical support and parts sales during their business hours.While this heater seems to be a good value it will only be so until the weakest part fails. Then you will need to purchase another complete unit and replace the whole thing if you need heat.

Excellent garage heater, mounted horizontally works well with wi-Fi thermostat.
