That's the one disparity that didn't completely make sense to me. I came
across one website that indicated that 10W were needed for every square
foot...approximately. So for my 20' X 20' shop of 400 square feet that
comes to 4000W. The unit I purchased produces 5600W, which supposedly is
equivalent (don't know the conversion factor on this one) to 19,000 Btu. I
guess I'll just have to wait and see how I fare. The price difference
between this and the Hot Dawg 45,000 Btu unit was $300 (not including the
venting and the thermostat for the Hot Dawg), and installation of that Hot
Dawg would've increased that difference.
The other factor was that I was told by one contractor that if my gas unit
caused a fire and I didn't pull a permit, my insurance company wouldn't pay
for anything. So pulling permits would've tacked on even more money. I'm
"comfortable" with having a person I know do the electrical work for the
electric heater without pulling a permit, but I was a little leary about the
gas unit when you consider the factor of the gas lines, the electrical
lines, combustion in the heater, and the proper exhausting of the
by-products. I guess I've got a little fear of the unknown to not pull
permits in that case...and so I went with the safer, cheaper option.
This is not likely going to be a permanent home for us, so I thought a
temporary, cheap solution might be prudent in this case, especially given
the complexity of decisions and the money involved with going with a gas
I suggest that the dust warning related to accumulation in the
heater which would reduce proper heat transfer - resulting in
overheating the element. The forced-air is probably only somewhat
forceful, so the unit should probably be blown out with compressed air
The insulating dust would also reduce the heating efficiency, so if
the unit does not suffer meltdown, longer runtimes would increase the
cost of operation.
No mention was made of a thermostat - is one available?
The propane or fuel-oil construction heaters have a more forceful
circulation due to the combustion which occurs in addition to the fan.
This unit does have a thermostat. As a unit "designed to be placed on the
ground", it probably is already going to see more dust exposure than a
ceiling or wall-mounted gas unit. Blowing out the dust (I do have a
compressor, thankfully) is a good idea.
