Good advice. I too use an electric radiator type heater in my basement workshop. It does not have an open heating element but heats the oil filled radiator. It has a thermostat so I am able to turn it way down when I am not in the shop.
However, they tend to draw a lot of electricity and when it is running and I turn on the table saw or shop vac, or any other device that draws a lot of current, it pops the circuit breaker.
Soo, I have to turn off the heater while I use any other power tool. Not a big deal but it requires a little prior planning.
