Water Heater Timer Project
I installed a timer on our electric water heater as my weekend project:
GE 15207 Hot Water Heater Timer
3/8" Clamp Connectors
10/2 wire (3 ft)
A couple years ago I participated in a pilot program with our local electric company using a Smart Monitoring system that allowed me to monitor and control our electrical usage to major devices. For us it was our heat pump, furnace, and electric water heater. The big take away for me from the program was how much our electric water heater was costing us. While I didn't store the data, I roughly recall that our water heater was costing us around an average of $45+/mo (and upwards of $80+ during the cold winter months). I felt during the winter months we could be saving an average of $10-$20/mo off our electric bill by using a timer to turn the heater off for overnight hours (6hrs/day).
Once the pilot program ended I've had it on my to do list to install a water heater timer. While in Home Depot the other day I saw some timers on clearance and grabbed one.
I found a few sites that were very helpful for installation including this water heater timer installation video and this site dedicated to water heater timers. It took me about 2 hours to install and didn't run into any issues when setting it up.
My plan is to have the water heater off from midnight to 6AM (1/4th of the time). Based on my anticedocal experience with our house, I'm expecting this will reduce our annual electric bill a minimum of $40-$80/yr.
Here is a previous post of other energy savings improvements I've completed.
Anyone else have personal experience with water heater timers?
