Basically the same type heater found in forced air heating in homes,Schools. Business's. Only diff is this has a custom tin cabinet built around it, so it is portable. Very economical to run,  heating elements can be replaced, all parts can be serviced, replaced. It is basically a heating element coil, a blower, and a belt, motor in a box.

Thats a great idea Gary   That could be a real economical alternative, especially if you could score a used gas one.

Are there any issues with using a gas fires heater in a dusty wood shop?

Hate to find out the hard way! Stic already had a pellet burner, so his dust collection must be adequate.

This is an electric 220 volt.
Not gas.

Not familiar with hvac unit. Is that all electric ?

HVAC units are generally used with duct work.
They can be elec, gas, or whatever.

The pellet stove has the burn pot enclosed with heat tubes that a fan blows the hot air out into the room. If the gas ones have open flame then there may be a problem. Thinking most of them have to be vented tho.

there are vented and non vented gas heaters, depends on your needs/concerns.   Another consideration is that most building codes and good practices will specify a minimum height above the floor for the install if there are flammable vapors present.

Tracey and I have been looking at these and It will do the job. and will be doing one in the near future.  Look at Menards to buy one they are cheaper there than what you found.  https://www.menards.com/main/heating-cooling/heaters/gas-garage-heaters/mr-heater-reg-big-maxx-dual-fuel-forced-air-garage-heater/f260550/p-1444441200665-c-6861.htm?tid=8940405124321896071&ipos=1

I had a couple of those types from overseas and did not get a winter out of them.
Make sure elements can be replaced and they have a good brand fan/blower motor

I have a 14 x 24 and bought one of the 30,000 btu overhead heaters from Menards. Working nicely.

Last summer I installed a 5,000 btu air window unit. Runs on low and works great!

Open flames and airborne dust can be quite explosive.     

 Bruce how noise is the heater? Are the flames contained or open to shop air.?

Just fan noise, not loud.

It was a special order to get one smaller than 45,000, not cheap. I think it was around $600 or so.

Beacon Morris Brut 30,000

Forgot to mention that it draws cold air from outside. There is a pipe in a pipe, heat thru the center, air on the outside of the inside of the piping!

I don't see any flames, but I would have to read up on the literature to know how it works.

Says that with a  • Combustion Air Inlet Kit  (For All Separated Combustion Installations)

And:

DUAL VENTING
Beacon/Morris "BRT" units are agency certified for both standard and separated combustion venting. Units are shipped to accommodate either category I or category III horizontal or vertical venting. With the addition of a Beacon/Morris combustion air inlet kit, the unit can be installed as a separated combustion unit.
