Hot taps don't flow until cold is turned on and off

[asktoby]

In my house, if I turn on the hot tap, no water comes.
If I leave the hot tap on, and then quickly turn the cold tap on and off, I hear a "thump" from the pipes and the hot tap starts flowing.
This normally fixes it for a few hours, and then the issue comes back.
This issue happens at many of the sinks in the house and also the two showers.

I took a video to demonstrate:

I also have a photo showing my plumbing system:

Is your water pumped and the pump pressure sensor is failing?
Turn electric off and try water.

I'm not aware of any pump. To be sure, I turned off my whole house electric at the main consumer unit, and was still able to draw hot and cold water.
