Why is my boiler losing pressure all the time?
Your combi boiler can be losing pressure for a number of reasons. Pressure loss may be caused from a leak in the pressure relief valve, an issue in the expansion vessel, air in your system, or a leak in the heating pipework itself.
What causes a Ferroli boiler to lose pressure?
If your Ferroli boiler is losing pressure, but you’ve checked there are no leaks coming from the radiators and no water discharging from the pressure relief valve, it’s usually a problem with the expansion vessel which will need to be repressurised.
What should the bar pressure be on a Ferroli?
1. Switch off the boiler. Ensure that there is no water pressure in the system. 2. On top of the expansion vessel (grey object with standard tyre valve on top, viewable from the top of the boiler) inflate with a bike or car pump to 1.5 bar (22 psi) 3. Charge your water system pressure to 1.0 to 1.5 bar. 4. Start your boiler
Where is the pressure gauge on a Ferroli boiler?
valve is usually to the right looking at the boiler from front above the boiler, firstly drain water from the radiator system so pressure gauge reads zero, then use a footpump or bike pump to pressurize the vessel to 1 bar (14psi).
What’s the boiler pressure on a Ferroli Optima 701?
I had the same problem on a Ferroli Optima 701. The pressure kept dropping to below the cutoff point, but when I re-pressurised (by topping up the water) to only about 1.2 Bar, it went up to 3 Bar when the boiler was operating, so that the relief valve vented.
