And the can't get costant access to warm water again!

I'm tired of that situation. Actually, at the place where we live now is no constant access to warm or hot water. The water heater is so small and old. It was bought as a second-hand item about eight years ago! When the water is getting hot, we can take a shower but watch out - usually there isn't enough water for two of us and me or my boy  Additionally, there are five people in this house. Parents of my boyfriend, the grandfather, sometimes Marius's sister and of course me and he. It's imposible to take a shower one after another even though the heater heats water for two hours :( halkap
