ive got a baxi 105e and when the heating is on the pressure shoots up to 3.5 bar and the water discharges through the pressure relief valve so needs topping up every day
OOPS. Sorry it is the safety relief valve (one end is red).

we had just the same problem and our E-On technician came and found the fault. He had to change the SAFETY VALVE -3 bar, chich he did after removing nearly a bucket full of water accumulated in the boiler.
