Hi all
I'm not sure if the title makes sense but basically today I was getting some work done. The plumber isolated my mains and drained the system down by opening multiple taps however I noticed afterwards that one of the taps opened up was a hot water tap.
My concern is the combi boiler will have kicked in to heat this water but as the mains was isolated the flow would have decreased until there was no water for the boiler to heat I'm not sure if this is an issue or not but I'd guess it works by a heat exchanger that is intended to have a constant flow of water over it I'm not sure of the ramifications of removing the water when the heat exchanger is operating. The boiler seems to be working ok in regards to producing hot water and heating rads however I did note that there was a distinct squealing noise from it when I used it
Also, on a side note, can anyone explain to me how the boiler knows to start producing hot water Is it a flow meter inside it that detects hot water tap is open and then directs the boiler to start heating it?
