CO is not something you can smell, you just have a few symptoms then drop. -----Original Message----- From: piclist-bounces@mit.edu [mailto:piclist-bounces@mit.edu] On Behalf Of= Bob Blick Sent: Monday, November 27, 2017 9:47 AM To: Microcontroller discussion list - Public.

Subject: [OT] Best garage heating option Hi all, I'd like to install some heating mechanism in my decently-insulated= garage for working on my motorcycle and some other projects over the winte= r. Initially, I considered getting a portable propane heater but I don't want = to mess around with propane tanks, exchanging them, the danger of setting s= omething on fire, and the fact that they vent directly into the room. However, this would be the cheapest option and definitely workable if I lif= t 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 th= e 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-phase = 240V power line into the garage and hooking up some powerful 240V electric = heaters. I'm not worried about electricity costs, since this will only be u= sed when I'm working on my projects, which is only during off-peak hours, a= nd not too many hours per week. These would also be the safest and easiest = to manage. I'm leaning towards electric since it would likely be easier to install and= overall cheaper considering the infrequent use case. I would appreciate any thoughts and advice on this.
