May be over kill but I use a Fire Demon to warm an open patio. People tend to keep their distance as it pumps out 47kw. It keeps us toastie warm on the coldest of nights. They are often seem in big machinery sheds on farms and do a great job. Burns diesel, kero, sump oil, cooking oil. 16 hours on a tank. Starts a bit smoky then burns clear. Probably spews out really really bad chemicals when burning sump oil. http://henstock.com.au/demon%C2%AE-heaters http://www.littlefarmco.com.au/products/the-%E2%80%98demon%E2%80%99-heater/ For your garage you would need to open the garage door completely and place the fire demon just outside On 27 November 2017 at 16:37, V G wrote: > Hi all, I'd like to install some heating mechanism in my decently-insulat= ed > garage for working on my motorcycle and some other projects over the > winter. > > Initially, I considered getting a portable propane heater but I don't wan= t > to mess around with propane tanks, exchanging them, the danger of setting > something on fire, and the fact that they vent directly into the room. > However, this would be the cheapest option and definitely workable if I > lift the garage door up a bit to let some fresh air in and mount a CO > detector nearby. > > The options I'm now considering are: > > - Natural gas heater - This will require running a natural gas line into > the garage which a professional will likely need to take care of, then > installing an expensive natural gas heater as well as setting up the vent= .. > - Electric heater - To be practical, this will require running a two-phas= e > 240V power line into the garage and hooking up some powerful 240V electri= c > heaters.
