Maybe a stupid question, but here goes. Will I wear out my hot water heater by shutting the fuse off and on once a day. Its just Dh and I at home and it seems wasteful to heat water all day long. I shower once a day in summer, maybe every other day in winter, he showers less. And I do the dishes myself, could just heat a bit of water on the stove for those times. I have already purchased a grey box timer for the water heater, but don't want to call an electrician until I have a few small projects lined up and the money saved to pay for them Thanks in advance. Mary.
