Hi Trudu, Yes, I am up the road from Cabo Roig ' Strip'.
The Boiler would normally have an Isolating 'Stop' Tap very near to it which can be used to shut off its water supply for Maintenance or in an Emergency situation leaving only the water then present within the boiler , and no more able to entetr it ,however , depending upon which type of system is installed, it could mean you would then be left with only a Water supply to the unheated ' Cold ' taps , including the Shower.
The Electrical supply to the Boiler can be via an adjacent switch or Plug and Socket arrangement and if isolated from there then no Electricity should be reaching the Boiler.
