I have a Vailant turbomax Boiler fitted and it seems to work fine.
The problem I have is when I switch the central Heating off, the pressure dial drops down to zero bar. When I switch the CH back on again it gradually rises up to 3bar and stays there until it swithces of on the timer. I have checked for leaks in the pipe work an i definatley have no leaks upsatirs or i would notice the water marks on the ceiling.
Any suggestions???
