Default Water heater improvement (Timer)

GE 15207 timer was $38 at Home Depot.



http://waterheatertimer.org/15087-15...Manual-eng.pdf

Before installing this timer on my hot water heater (actually my oil burner),
I tested it with my Kill-A-Watt and got no reading.
Used the VOM AC Amps and saw 0.02 Amp that's about 2.5 watts, so it's a keeper.
The meter reading was less than 0.01 Amp without the two relays energized.
(When the water heater is off. Clock motor only).


It's a simple mechanical timer that does 30 minute increments.
Can run on 120, 240 or 277 vac. (This is the indoor version).
Not as fancy as a battery-backed-up LCD unit, but it's a lot less money.
It can handle 8,000 watt loads, so my little burner should work fine.

I'll try to post some pics of the install.

Cheers,
Rich
