We had a new bathroom fitted last year and I noticed straight away that when the hot tap is fully on, the water is only luke warm. It needs to be on about midway to get hot water. We had a corgi guy come to look at the boiler, as I was concerned that it sounds constantly as if it's firing up when the heating is on (a whooshing sound) but he couldn't find anything wrong.
More seriously, ever since we've had the heating coming on in the mornings this winter, the shower is freezing cold with just a few warmer bursts. This makes showering a miserable experience!
Does anyone have any ideas what might be wrong? The corgi guy hinted the boiler might not be up to the job, but it's only 5 years old and we live in a one bed flat so that didn't seem a likely explanation to me - though he's the expert of course...
Any advice appreciated. Many thanks.
