When we had the old back boiler it wasn't wise to drink water from the hot water tap (ie from the copper tank).
Now we have a new combi boiler, I was wondering if it's OK to drink water straight from the hot water taps as the hot water comes, effectively, direct from the mains.
I find that the temperature of the water from the hot water tap is just about right for a quick cup of instant coffee!
TIA.
