hot water heater not so hot? turn it up!

D been complaining that we doesn’t have enough hot water – runs out for during a long shower.  She says it is a recent behavior in the past couple of months.    I have noticed at times that a shower is just fine but I sometimes have to set to the maximum  hot setting on the shower valve.  I take shorter showers.  This has been long-standing I believe.  Also note that it is winter now and it is about 10 degrees colder in the house than summer.

I have been wondering if we should replace the heater even as a pre-emptive measure.  Friend Cowboy who is a contractor thinks it should be good to go for 15 or 20 years.  For now, we’ll play with it.  Couldn’t hurt to drain it one day either and see if there is corrosion.

Today I made thermostat changes.  Turned off power to heater, adjusted, power back on around 1125.  The two thermostats look different ( i.e. bottom is just a screw, bottom has pointer and A B C markings ).  Both adjust with a flathead screwdriver.

1/8/17:  made an incremental adjustment to increase temp to top and bottom thermostats:

  1. Top element, moved set dial from 4 o’clock to 6 o’clock with flathead
  2. Bottom element, moved dial from full left to “A” position.
