Forgive the naivety, but I've never lived anywhere that was electric only and I'm having some trouble with the hot water in the shower. There is a pull cord with a off/on indicator and a separate red light (which is always on regardless of off/on status), but there are no other buttons or things to fiddle with, just regular (separate) hot and cold handles for the faucet.
The problem is that the hot water runs out after about one shower's worth regardless of whether the pull cord says off or on. So my question is this: am I using it wrong? Does the cord need to be pulled 'on' all the time? Does the always on light mean something is broken? The hot water from any other faucet in the flat doesn't ever run out, so I doubt it's a problem with the boiler. Any suggestions on how to use this silly shower are very welcome! Thank you!
