Considering the always rising cost of electricity, if I were you, I'd explore alternate and less costly alternatives if you have alternative fuels available.
Those work, but I would never use one in a shop with solvents, fuels, or dust. I think the fire risk is significant compared to a ceramic style heater that has lower temperature elements or an oil heater.
1475 watts won’t heat anything not right under it. It certainly wont heat a space. You’d need at least 220v to do that, and even then electric would be weak
I'd definitely prefer some type of heated oil option to anything quartz or electric filament style. Every time I see an electric quartz or filament style heater, I cringe at the fire hazard. I understand they all have tip-over protection, but what about a piece of cloth or paper laying up against it?
Edit: Of course, I say this while I'm sitting in front of a Dearborn gas heater at deer camp. In my defense, we do have a working smoke/CO detector and fire extinguishers. The Dearborn has sat in the same place for 50+ years.
That's the exact one I bought years ago. Gave it to the SIN as you could only feel it while under it. I ended up putting a 4,500W electric heater in the garage that I don't use unless I have to. You can almost hear the meter spinning when I turn it on.
I bought a cheap 80,000 btu propane radiant heater last year. Coupled with a 40lb tank, I can get about 23 hours of heat out if it on its lowest setting of about 25k BTU
I had a propane catalytic heater in a small shed years ago. The amount of moisture it would put in the air covered all my tools with condensation...gave that to the SIN too LOL.
