Mr. HeaterMH125FAV 125,000-BTU Forced-Air Propane Heater, Black

Used this twice. Second time being a 20 amp circuit and the homeowner replaced the outlet with a 15 amp making me believe it was ok to plug this in. As soon as I pressed the button to ignite.. a little puff of smoke came out and it was done. Gas and fan worked but no igniter. BAD DESIGN. Also be prepared to buy a 100 lb tank. This sucks down the propane. On a positive note.. I have a 28 x 30 garage with pretty much all open construction and this unit gets the garage warm fairly quickly (1/2 hour - 45 min~ ) and maintains a decent warmth in winter.

This is a FANTASTIC heater but there are some things a new buyer should be aware of. It'll bring a 30x60x12 garage from 0 to 60 in about an hour and a half. However you really do need a 100 lb tank. You can get away with a 40 or 50 lb heating a smaller area on low otherwise the tanks will condense and shut off the gas flow to the heater. They are louder than you'd expect if you haven't used one of these before because of the blower fan. Think mini jet. I've also used the convection style heaters and depending on your needs these are both great. The convection style is much quieter but takes a fair bit longer to heat a large space and you won't get as even a heat in the room. For larger spaces or fast heat up the forced air heater is an awesome product. Mr. Heater MH125FAV 125,000-BTU Forced-Air Propane HeaterMr. Heater 80,000 BTU Propane Convection Heater #MH80CV

Its like a giant giant big a$$ heater/ boooozooa. Used it for heating my garage! It shoot out giant flame at the end. EZ to start just like a BBQ grill. Push buttton click click after you get the propane dripping. Make sure the seals are good and tube connected well before you start. I have it connected to a 100 gallon tall propane tank. It burned for hours and hours while i worked on my baby! High recommended. You can NEVER have tioo much heat! You can also adjust the BTU size if it gets to hot hot hot!

I'm in the process of insulating and paneling a 12x30 portable building to be used as a workshop. During the winter it get's a bit cold here. I got this hoping it would heat the building enough to work comfortably. I couldn't. Kept having to turn it off after every 15 minutes of run time and wait 45 minutes to an hour before needing it again. That's a lot of heat from a device that's slightly larger than ones thigh. It uses very little propane for a LOT of heat. I heartily recommend it.

We bought it and it worked for a while. After a few weeks, it would not ignite . We were sent a new board which did not fix the problem. Called tech support and we were told to by pass the high heat sensor with a paper clip. I cant see that this is an acceptable practice to override a safety feature.Then we talked to the next level person and they asked us to jump across the two wires that come from the circuit board to the high limit sensor.Come on. Never again.

puts out a lot of CO. I wish I would have bought a large electric heater instead. It does put out a lot of heat.

Very noisy and not to fuel friendly. Not what I would recommend for heating your garage or shop. More for new construction !

This heater is very nice. Puts out lots of heat fast. The only thing I dislike is that you can not put it on a thermostat, so it would shut off and come back on by it's self.
