It’s easy to miss changes when they happen gradually. Water heats slowly and you wouldn’t notice it until it’s too late. This happens in reverse too. I just had my water heater replaced because I didn’t really have hot water anymore. I had a small amount of lukewarm water. It sometimes got hot, but not often, and not for very long. This happened over time.
Now that I have a working hot water heater I realize what I have been missing. Sometimes the water is too hot and I have to turn it down. I don’t remember the last time I had to do that.
