Trekker,
shows you don't have a baby.
If you hear a baby crying...probably mine! He can't stay in the stroller for more than 10 minutes. I wish I had one of those kuai kuai babies who seem to be able to do everything (eat, sleep, drink milk, be entertained) in their strollers...mine wants to be carried.
Green Apple,
I've always had that 'bong' sound whenever I turn on the hot water - from day one. Mine does take a while (2 - 3 mins) to heat up but once it's hot, it stays hot. Mine's on to the max and it's on all the time... ya, considering all things, maybe an electric heater would be better.
Trekker,
I grew up using storage heater, that thing took like 10 mins to heat up before I could shower. My parents came for a visit and they turned on the "water heater" switch and left it on for a while...I saw it and asked that what they were doing...it's not connected to anything!
