Need a garage heater, I have 120 service and natural gas rough in already in a ceiling corner. It’s an attached garage, insulated, 1000 sf, 10-11 foot ceilings, 2 garage doors, 3 windows and 2 service doors. I am looking for something to keep it around 40 when I’m not using it but I want something with enough BTUs to warm it up to 50-60 when I will be working in the garage. Three are more brands out there than you can shake a stick at, and like everything I know you get what you pay for, but I have seen some as low as $400 and some as high as $1400 for the same BTU capabilities. Any brand suggestions, install tips, size? Online they have a size chart but it ask what temp you want to keep it at, so I have been plugging in my temp I would like it to get to even though I’ll be keeping it at a much lower temp 90% of the time. I have also been leaning towards forced air since i want to ramp up the temp quick and then bring it back down, but would it be smarter to spend a little extra $ and go with NG radiant heat? Are they as efficient as they advertise, can you still adjust temps with them or should it stay a constant temp? Thanks for the help!
