Answers: The expansion vessel probably needs recharged,if you enjoy a footpump with a appraise on it you can check/recharge the air within it.Pump it up to 0.5-1.0 bar,the upper air valve is customarily located at the top off the boiler,at the put money on.Make sure the gauge on the boiler is at zilch before you check it.
It could be the expansion vessel desires recharging, or it could enjoy ruptured internally and filled completely beside water.
Also depending on your boiler spawn, the pipe going to the expansion vessel may be blocked.
If you can get to the little tap on the vessel, it looks like the one you find on a car tyre. Undo the bonnet and press in the tap quickly, if marine comes out you need a up to date expansion vessel, it should be air coming out. If not it may freshly need to be topped up. You entail to drain off the heat system pressure and with a pressure determine see if there is around 0.5 public house. If there is, later pipe to it is blocked, if not recharge the vessel next to a pump
Your pressure differential valve is on the blink, and you are losing water out through your boiler overflow pipe. This spigot is a one way stopcock which holds the water pressure on the boiler. When it become faulty, marine can leak put a bet on out of the valve. You will hold to have a unusual one fitted, they cannot be repaired.
