Why Has My Boiler Pressure Dropped?
If you’ve noticed your boiler pressure has suddenly dropped, don’t panic. It’s a common problem that we see on a regular basis, and in many cases it’s something that can be resolved quite easily – and crucially, without costing you a fortune.
Most modern boilers work best when the pressure sits somewhere between 1 and 1.5 bar when the system is cold, although this can vary slightly depending on the manufacturer. If the pressure drops too low, your boiler may stop working properly or display a fault code.
Often, the first time you will realise that the pressure has dropped is when you can’t get any hot water or your radiators are cold when the heating is meant to be on!
The good news is that low boiler pressure isn’t always a sign that you need a new boiler. Sometimes it’s simply the result of a minor issue that can be identified and repaired before it becomes a bigger problem.
