Hi Hi......I am not a regular here......Just login to check if there are any tips on storage heater. PLease do NOT get CityGas!!! I just installed it because it is free and I begin to regret my decision. The water will only get heated up after you turn on the tap. I need to leave the tap running for 1min in the kitchen before the water is warm. I need to leave the tap running in the bathroom until it fill up half a pail of water before getting warm water. So you can get warm water immediately after the first one shower. But the first person who shower got to let the water run for sometime before you get warm water. I find it totally unacceptable and call in the citygas maintenance guys. They said they cannot do anything about it cos it is due to the long piping, that's y it take so long to heat up. Well, unless you live in old flats where the toilet is beside the kitchen, I don't think you will have the same issue. According to him, TPY 79 blks, Tanglin Halt and SengKang faced the same issue. So looking for alternative solution now. What a waste of time.
