Can you reduce consumption and schedule hot water?

> A Water Heater Timer is a good idea.
> It requires changing what we think about hot water.

Everyone shops for lowest cost energy. People turn off extra lights and program heat/AC units to save energy.
Most agree a water heater timer is a good idea.
But barriers exist.

People expect always-ready hot water. We resist planning for hot water and prefer old habits to new ones. American homes have one (or more) water heaters that run full-time keeping water hot-n-ready. Some homes have circulation pumps for immediate hot water at each faucet.
A staggering amount of energy is spent delivering the ideal of plenty.
Times have changed. We can't sustain the same energy consumption as before. More homes and businesses are built each day. The demand for energy is growing, coal and gas vary in price, the electric grid needs overhaul, hydrocarbons are harder to pull from the ground, so prices will go up.
As a result, change is here.
Change is slow, in ordinary times.
For example, programmable thermostats for heat-AC came on the market in the late 1970s. Yet programmable thermostats did not become standard until the mid-to-late 1990’s. In the past, it took 15 years for change to take root.
Change is faster today.
A Water Heater Timer lets you control energy costs, and protect yourself for the future.

> For shower, turn on electric water heater 15-25 minutes. For gas, it takes 10-11 minutes.
> For bath, turn on electric water heater for 45-60 minutes. For gas, it takes about 20-35 minutes.
