The cold water supply entering a water heater may drop as much as 25 degrees during the winter. This temperature difference will cause a water heater to recover much more slowly.
A 40 gallon water heater can only deliver about 27 gallons of usable warm water. Its very easy to use up hot water without realizing it.
As sediment builds up in a water heater, it takes more energy to heat the water.
Its a good idea to flush a water heater every 3 months in areas with hard water.
Excessive sediment is the major cause of low hot water pressure.
