Tips
for choosing & installing water heater timer 1. Re-setting timers after power outage is inconvenient, especially when located outdoors after thunderstorm. 2. Check timer has enough on-off periods per day or per week 3.It is difficult to reset timers located in remote locations requiring flashlight, for example in attic or cluttered utility area. 4. Put timer at eye-level In-wall timer is more difficult to install, but gives easy access, and adds value to home. Back to all timers |
