Sorry for a bump...just my personal opinion... I don't like propane because you never know when you're going to run out, and it's not good to keep the bottles in the garage. I use a radiant style torpedo (a lot quieter than a regular torpedo.) It's 70,000 BTU. I tun diesel thru it and keep the man door cracked. I don't notice any fumes. I use that to get things up to temp before switching on my electric heater. It heats my 24 X 32 up to about 80 from 40 in about 15 minutes. The propane unit you showed just heats the direct area where it's pointed at. Not a lot of circulation unless you buy a fan. So for the price of that unit, plus a fan, you could buy a radiant style torpedo for about the same money and have heat circulation plus more BTU's.Kerosene house style patio heaters are good too https://patiotip.com/best-patio-heater It will take it longer to heat up the area though.And with all kero/diesel/propane heaters in garages, a 20-30$ CO sensor is a good investment.
