Waiting for hot water

[judy]

I am not used to living in a house, waiting for the hot water to kick over so that I can take a nice hot bath!!! Grrrrrr! And then, when I get in, I can't add more hot water to keep it warm because it gets used up.

I think there might be something wrong anyway because I can't fill the bath up before the hot water gets used up. I don't use hot water for a good while before I fill up the bath. Then I fill it with only hot water and wait until it cools down just enough so that I can get in and enjoy it.
