My day job is large industrial power supplies. The test racks have large resistive loads with big fans exhausting to the outside. Cheap & simple. Safety is by several strings of temperature cutouts wired in series. We usually get work experience students in to wire them up.
Tip: to make a funny valued power resistor, just get the next value up and wrap some nichrome wire around it to bring it down to the correct value. I met an engineer who made a battery charger for one of our submarines. This was tested by putting the load bank in a dumpmaster, and keeping it filled up with water using a firehose!
