Depending on how your tap water is made hot, drinking it may be ok: if you have an electrically heated tube-coil that warms the water just as it is flowing, or if you have an heat-pump system also with a last-second water-heating flow through the heat-buffer. Then you are ok. Any hot water that is kept a while before it goes out the tap, you should not drink. Also of course it must then be kept above 50C, or you've got a serious bacteria risk. This is assuming the plumbing is not lead, but who the hell has leaded plumbing still?
