it is electricity that heats the cold shower water,check to see if a fuse has blown,also did you turn the stop cock off or down so reducing water pressure,things can happen in two,s

air locks in the pipes maybe. all sounds very strange

check for mineral deposits blocking the water heater intake preventing water from getting into the unit

it sounds as though you did have low water pressure when they were working on the piping system. it seems to be OK now as it is under pressure but. you are not getting hot water. the lamp says ‘low water pressure’.
most likely occurrence is that the work on the system has released mineral deposits that have travelled along until they got to You shower unit. it may well have an internal filter which is partially blocked. also it may be a fault withing shower unit itself that is Simply indicating ‘low’ pressure when in fact it isn’t. here we need ot get somebody top have a look at the shower unit as suspect prime problem .

Your kitchen sink cold tap is probably the only one that is connected directly to the incoming mains water pipe. If the water pressure from that is what it should be then the fault is somewhere inside the house pipework.

It is common for all other cold water taps, electric shower feeds and toilets to be fed directly from the cold water cistern in the attic. This maintains a cold water pressure that is equal to the hot water taps, which are fed from the heat exchanger in the airing cupboard cylinder (which is also fed from the tank in the attic).

Check that the big tank (cistern) in your attic is filling properly. If it is always partly empty or fills slowly then that will reduce your “head” of water pressure for everything except the kitchen cold tap. If someone draws water or pulls a flush then the pressure will drop for someone taking a shower.

The cistern may be suffering from a faulty ball cock (float valve) or from a partially closed gate valve (the ones with the ring type handles) in the airing cupboard.

The shower will be reacting to low incoming water pressure. If the pressure drops then the thermostat will try to reduce the heating effort but because of lag in the system it can’t keep pace with the water pressure fluctuations and so you get temperature variations.
