If you are dealing with vehicles then I would be reluctant to see a heater = with a naked flame (either of the gas options) or exposed heating element (= electric radiator) around exposed potentially volatile fluids. I would suggest an electric oil radiator or two arranged around the working= space. With several of these you probably don't need a two pahse 240V sock= et, but rather several 110V ones. > -----Original Message----- > From: piclist-bounces@mit.edu [mailto:piclist-bounces@mit.edu] On Behalf > Of V G > Sent: 27 November 2017 08:38 > To: Microcontroller discussion list - Public. > Subject: [OT] Best garage heating option >=20 > 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. >=20 > 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 l= ift > the garage door up a bit to let some fresh air in and mount a CO detector > nearby. >=20 > The options I'm now considering are: >=20 > - 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 instal= ling 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 electric > heaters.
