Add Countdown Timer for Electric Heater

heatertimer

I have a ceiling mounted 240V 30A heater that is currently controlled by its built-in thermostat. The heater is in a workshop (in an out building). The heater is wired using three wires (two hot and a ground).

I'd like to be able to add a countdown timer so that I won't have to worry about forgetting to turn the heater off when I leave the workshop. Maybe, one that could be set for up to an hour.

Thanks in advance for any help you might offer.

Just to answer your question, you could always use a common Intermatic double pole single throw timer. You'd have to have a fixed "off" pin and just rotate the time wheel to an hour before the "off" pin each time you used the shop.These timers are relatively inexpensive and available everywhere. It would also give you the ability to set the heater to go on at a certain time so it's warm when you get there. enter image description here

Another alternative would be to get count down timer from a heating supply company. They're good for up to a 6000 watt heater. They are over twice the price of the Intermatic
