Actually, building the 7 day programmable WH timer isn't all that expensive. Get a contactor with a 120V coil and 240V load side. Get a plastic project case to contain the contactor. Get the #95205 digital timer from harbor freight to operate the contactor. At this point, you might be in for $30, but you have an 8 On/Off digital timer.
I don't have crumb crunchers, but I am running an idea I found on waterheatertimer.org It uses an old Decora switch sized Intermatic 7 day programmable digital timer I bought from my local Habitat ReStore. I'm only using 3 of the 7 on/off cycles available. I still don't understand why most water heater timer manufacturers still use mechanical timing devices?
The HF digital timer I suggested above is actually more sophisticated than my Intermatic timer. The HF timer will do groups in addition to individual days, groups can be: MTWRFSS, MTWRF, MWF, TR, SS (M=Monday, T=Tuesday, etc). The Intermatic doesn't do groups of MWF, TR. I really need to get another one and gut the mechanical timer out of my sprinkler timer. I'm using that HF timer to cycle the dehumidifier in my garage.
