I've tried ALL kinds of locally-manufactured water heaters and none of them are satisfactory. When I turn on the water, the temperature I selected does not remain constant--the water just gets hotter and hotter and hotter and hotter until I have no choice but to shut it off or mix it (and continue mixing it) with water from the cold water tap. MUST I order my water heater from Singapore, which is most probably actually from the UK? I wonder how many other modern pretensions this country has that are there for me to further discover.
