Evening Gents, just a question about the block heater. Does it run constantly or does it cycle as it needs it? Thanks!

Constantly. There is no thermostat built in.

Thanks MaxPower, guess I'll use the Christmas tree timer.

I'm not a tech but you're going to want to use a heavy duty timer to handle the load. They draw somewhere around 7-8AMPS or about 900WATTS.

Kinda overkill, but I have a 15 amp timer. Originally bought for 3/4HP pump.

Home Depot has Block Heater timers for about $19. They are supplied with approx. 12" of supply cord and are suitable for exterior use. The local one had about 2 doz. recently.
