Mr. Heater 80,000 BTU Garage Heater LP / Natural Gas

For the last few years we have had a real hard time with winters in the garage and traditionally we have used torpedo heaters, from kerosene which is about the worst, on to the natural gas units to at least keep up a minimal existence thru the winter... often times we would end up closing up for the most part in January and February because it was just impossible to keep the garage warm and not kill yourself with the amount of fumes.

This year we opted for the convection Mr. Heater garage heater with LP gas conversion @ 80,000 BTU... since we waited so late in the season we could not get a gas line run in time before the freeze... that said I had to convert the unit to LP gas if I was going to have a convection heater this year. I was amazed at how well the conversion went with nothing more than some pipe sealant. I also picked up two 100lb tanks from Menards, which just happens to be the same place I picked up the heater. Each of the 100 lb tanks was about $120 each and cost about $100 to refill here. The heater I think was a little over $500.

Given the fact that I still have a lot of insulation and hollowing out of my roof to allow full lift on my hoist the heater has been temporally installed until this project gets finished off. Here are some of the photos in the rough while it was being converted, test fired and then temporarily hung.

So far the heater has been working great! It heats the entire garage in under 30 minutes and if left running it will get too hot! Look forward to seeing how it works in the deep chill however this year I should be able to work with the really cold northern temperatures and the best part is it's clean heat no nasty smell or loud fan! Very impressed so far and I just hope it's a quality unit that will last a good 10-15 years. 

I get about 3 days of use out of each tank @ about 6-8 hour days but this has been at temperatures in the mid 30's... It may need to run more in the colder weather however we should treat this as almost an un-insulated garage since the roof panels have been removed to gain access to the upper roof. Hopefully once it's insulated proper the usage will lower as I do eventually plan on having a line run out to the garage for natural gas. I saved the old parts so I can convert it back.

I'll update the thread as time goes on.
