I have an Ariston EuroCombi (SX 20 MFFICE) installed, and I am experiencing significant fluctuations in water pressure. I.e. swings of +3bar to 1 bar over several hours, sometimes resulting in water being dumped through the pressure release valve.
As an interim, I have re-pressurised the system each time. The radiators have been bled and have checked for possible leaks in the central heating system, but found none.
Any suggestions?
