I have had the worst time trying to heat my garage, however i do a lot of work in my garage, so I like to have it at least sort of hot in there. I prefer it to be around fifty degrees in the garage. It is the perfect temperature while I am laboring. It does not feel too hot or too cold. At first, it is a little chilly, but once I beginning laboring it feels perfect. I have a sizable propane space furnace in my garage that I have been using for the last couple of years. It is the only furnace that I have found that keeps the garage around fifty degrees. It is still a pain because it takes about three hours to heat the garage to that temperature each afternoon, although I recognize it is worth it in the end, but unluckyly, my furnace is not doing well. I have made sure that the propane tank is full, and I have tried everything I can to clean the thing, but it still is not laboring right. It just is not putting out the heat that it used to, and it is getting harder and harder to ignite. I have thought about replacing a few parts like the thermocouple, but the furnace is so aged that I figure I should really just go ahead and buy a whole new one, however my spouse told me that he would buy a new one if it was him. I have been looking at a few different stores and online to find the cheapest place to buy a new one… Thankfully, they are not actually overpriced, so I should not have any concerns either way.
