I mentioned a while ago on this forum that I'll do the heated garage. Winter is coming fast and I just got a quote from a contractor.
One of the things he recommends is a Beacon Morris 45K btu garage heater for about $700. I don't know anything about these garage heaters. Is this a good brand? Good price? Your experience with it or other brand?
One of my concerns is this heater will be covered with dust since I intend to use the garage as my woodworking shop. Is that a safety issue or a major pain to keep it clean, or potential problem to run the heater in such an environment?
I've got an open-flame heater in my garage / workshop and don't have any problems. I do practice a few things in the name of safety:
Periodically I turn off the heater (and pilot) and use my air compressor to blow out the dust.
I do my finishing on the far side of the garage, maximizing the distance to flame. Before using flamable finishes / solvents in the winter I get the garage good and warm and then turn off the heater/pilot as well as my water heater and house furnace before opening them up, do my finishing and let it surface dry and then open the garage door for a few minutes to get some air flow in there before re-lighting the heater. Fortunately for me they are all in one corner of the garage. The overhead door isn't open long enough for any fear of freezing and I haven't experienced any negative impacts.
If I was doing something large, like spraying an entertainment center with flammable materials I don't know how safe it would be. For those I'd probably use a different finish or hold of finishing for spring. <g>
Here in Anchorage garages are very popular, virtually all insulated and heated with open-flame heaters (like my setup) and its rare to hear of a fire. The only two I know of were both gasoline fires, where the water heater was setting on grade. Here in Alaska, code requires them to be on raised platforms since gas vapor is heavier than air but some old houses were "grandfathered" in.
Just another source of information for you. Compare it with what you hear from others.
Just because something has been done so far without injury doesn't make it safe!! Use your own judgement!
