Magnetic Block Heater

[grsthegreat]

The magnetic heater has its place on some small motors like generators (mine holds 2 qts of oil), but they do suck up 250 watts and lose alot of that heat to the air. I put mine on a plug in thermostat so it only runs when temps get below 38 F and shuts off when it gets above 45 F. 250 watts x 24 hrs x 30 days = 180,000 watts or 180 KW @ $0.06/kwh here in n idaho = $10.80 per month if running 24 hours a day. Wont break the bank

I've had a magnetic heater for many years. They can be usefull for lots of stuff including an oil pan heater. Not sure I ever tried to put mine on an engine block. As said.....a block heater is much more effiecent and gets the job done correctly.

Most often, a magnetic heater is more of a band-aid approach. Still....a band-aid can be handy to have around. In Minnesota we are always looking for some way to warm things up. :thumbsup:
