- What causes a drop in pressure? There are two leading culprits when it comes to low water pressure: Leaks. You may have a leak somewhere in your boiler system.

For your boiler to work at its best, your ideal water pressure should be between 1 and 1.5 bar. So, if the pressure's not quite high enough, adjust it carefully using the filling loop. See our how-to guidefor more on boiler pressure issues and their fixes.
If your temperature is set below 21℃ your boiler might not come on at all, so you'll need to increase it. If you're not getting any reading on the thermostat panel you might just need to change the batteries.
Power cuts and accidental knocks can throw your boiler's timer out, so double check that yours is still set correctly and adjust it if not. If you're unsure about how to reset the timer on your system, check your boiler manual.
