Should Boiler Pressure Drop To Zero When Not In Use
Should Boiler Pressure Drop To Zero When Not In Use. Been doing some research on the forum's and think i may have nailed it but wanted a second opinion. I have restarted the boiler etc and filled it upto 2 bar.however this took approx 1 min to drop to 0 bar.

Attach the hose to each side of the valve and open the mains cold tap. Hopefully, the boiler installer dosed your new system with inhibitor and fitted it with a scale reducer (in hard water areas) and a magnetic system filter. Once the pressure has gone, most leaks will only drip very slowly and maybe not at all.
On Most Digital Gauges, You’ll See A Flashing Pressure Reading, If There’s A Low (Or High) Pressure Warning.
The amount of water which needs to be drained away to drop the boiler pressure from 3 bar down to zero is usually no more than 10 or 15 litres. The pressure relief valve outside is wet/dripping (although i don't know if it only drips when the heating is off, or whether it's dripping all the time). Dropping below 1 bar, often to zero), but only usually when the heating is turned off.

The Red Area Tells You When The Pressure Is Too High, But Watch Out For It Falling Below 1 As Well.
But be sure to close off the filler valves afterwards! It stands to reason there is a leak somewhere. At this point i have to let water out of the system to get the bar down to 1.5 again, just to have heating & hot water through the evening.
I Don't Always Remember To Do This, And It Doesn't Seem To Be A Problem.
Boilers are built to quickly control these jumps in pressure via the pressure relief valve. Watch the pressure rise and stop once the bar reaches just about one and turn off both taps. If your boiler pressure keeps dropping, there’s a good chance you’ve been told to use the filling loop to “top up the boiler”.
