Hi, Our gas 40 gal hot water heater does not keep a constant temperature unless it is used every 3 - 4 hours. My wife gets up 45 minutes earlier than the rest of the family and the water is noticeably cooler when she showers. Also, if we are away all day and a bath is run, it runs out very quickly. After vacation, we put a load of washing through and wait 1/2 hour before we shower.
Is this usual for HW heaters? Once it's used during the day it's fine, three of us shower in a row and it's hot enough. It seems that as long as it gets intermittent use it's OK.
I would appreciate any comments.
Thanx,
