i have a possible job to sort a direct hot water cylinder. the customer suddenly got no hot water. they turned off the immersion heater a few months ago and haven't used it since. i checked the thermostat and it was set at 40 degrees, i changed it to 60 degrees and turned it back on. tried to get hot water out but nothing came out of the tap, no spluttering, nothing so i guess that rules out an airlock (or does it?).
the building is quite old and lead pipe is used to both cold inlet and hot outlet.
the cylinder does feel quite warm to the touch when it had been on for a bit.
so what do you reckon? is it the immersion heater, the thermostat or a blockage in the maze of pipework. the cylinder is dated 1999.
also any advice on cutting into and joining lead pipe to copper?
thanks
andrew
