what make and model of boiler is it?

what exactly is happening with the hot water? is it going hot and cold hot and cold or is the boiler shuttng down altogether and going to lock-out?

i dont know any boiler that operates at 0.5 bar, they are usually 0.8 to 1.2 bar with 1.0 bar being the norm. try topping the water in the boiler up to 1.0 and see if that helps.

Hi leeandjoanne, Some of the Saunier Duval boilers have a built in filling loop under the boiler. If the digital display shows pressure less than 0.7bar, re-pressurise the system to 1bar by gently opening the built in filling taps underneath the boiler. Tap extension tools are provided to facilitate this. Using the tap extensions connected to taps open one tap and then slowly open the other tap. Re-pressurise the system to a pressure of 1.0 bar indicated on the digital display. When the system is pressurised you must close bloth taps. On older Saunier Duval boilers there is a seperate filling loop you will have to locate it, usually is quite near to the boiler under it attached to the pipes and has a silver braided hose and taps on either end you need to attach the hose and open up the taps untill correct pressure then close both taps and disconect the hose.

This was happening with our boiler until we got it serviced. THe man said it was just dirty and cleaned it. Not sure where he cleaned it though.
