You never mention how many square feet you are heating ??? My shop/garage is is the typical 20x20 foot
garage or 400 sq/ft. The price might be OK when pulling permits, including cost of heater, installation,
labor and profit.
I bought a Hamilton 45K BTU natural gas Forced Air heater on Ebay in March of 2008. I did not pull permits,
but that is something only you can decide on for yourself. I have a hot water heater in the garage closet, so I
had a NG line close by. I installed a tee and checked with a soapy solution for leaks. I also had saved a Honeywell
round thermostat from the house that I used and installed just inside the door to the garage. This made it really
easy to just open the door, flip the thermostat switch to ON and go eat breakfast in the morning. In 30 minutes it
would be 68°F to 70°F when it was 45°F outside. I have installed insulation in all but one outside wall, including
the ceiling.
Personally when you have NG as an option, I don’t see why you would use anything else. You would never have to
refill a bottle, never have to go without heat because you didn’t have time to run and get a bottle filled when you
wanted to complete a project and leave for an event. Maybe the only reason would be that you don’t need a permit
for some reason ???
I have replaced 80% of all my soffits, anytime I replace something on the house I use screws instead of nails. So all
I had to do was unscrew the soffit to gain access to work around the vent.
I uploaded the manual for the Hamiltion heater if you want to read all the particulars for installation, just page
down to the bottom to find it.
