Getting that EH40 Electronic Water Heater Timer. From what I have seen , most of the time, it is installed near the water heater or near the Circuit Breaker Box. Electric Water Heater is in the Basement. Arthritis is getting pretty bad. Don't really like to climb stairs , if I don't have to. Can that water Heater Timer be installed on the wall at the top of the stairs that go down to the Basement ? It would me from going up and down those stairs, if that timer were attached somehow to the wall at the top of the stairs
