I would like place my electric hot water heater on a timer is this possible. If so what type of timer would be looking for.

Something like this Intermatic WH40 Electric Water Heater Timer Single Pole 240V 40A (http://www.google.com/products/catalog?hl=en&q=electric+water+heater+timer&wrapid=tlif129676223731410&um=1&ie=UTF-8&cid=710712341878854688&ei=hwVLTebzFoaBlAf1q9nYDw&sa=X&oi=product_catalog_result&ct=image&resnum=1&ved=0CEAQ8gIwAA#) would do the trick.

HD and Lowe's sell a timer for a 240V HW heater. I will assume it is 240 not 220. I use one in a vacation home and it works well.
