I purchased a Ruud pacemaker water heater about six months ago and it also was installed with a small reserve tank. I am having a problem that I am not sure is related to the type of water heater, the reserve or is to be expected. If we have not used hot water for a period of time, say overnight, the water is cold. In order to get hot water, we need to run the hot water for several minutes. We then hear the heater turn on and in a few minutes, we have hot water. It will then remain hot for most of the day. What do you think?
Thanks for your help!
