I have a problem that has stumped my neighbor who is a plumber...the first shower (or any use) in the morning is cold water. But a short time after the first use the water is hot. In order to get a hot shower first thing in the morning I have to run the dishwasher on the timer to begin at about 3:00AM to get a hot shower at 5:00AM. Why doesn't my 7 year old water heater maintain the hot water temperature for prolonged hours of non-use (i.e. any period more than about 5 hours)?

May I suggest that you search on the word "deadband" and read another post further down in the board on the same subject? You're not alone. :wink:

Thank you for your reply. I read your "deadband" response as directed. But you mean to tell me that you live with this cold water problem every morning? Running the water for 10 minutes prior to the first shower every morning is not only inconvenient, but seems terribly wasteful.



Would a new thermostat correct the problem?

Hello: The thermostats in modern heaters are not very responsive to slow temperature change. A way around that which would increase satisfaction is to install either a recirc system or a Metlund type system. A normal recirc system requires running a return line back to the heater. The Metlund ( http://www.gothotwater.com) does not. Either system will put cool water back in the tank, making the thermostat wake up and turn on the heater. A normal recirc would use a timer set to run 10-15 minutes before you need hot water, or with Metlund, there is a remote control you could push on getting up. In addition to getting the heater up to temperature, you would have quick hot water. Hope that helps.



Yours, Larry
