We have a combi boiler which has just been serviced. The guy did say that we would need a new one soon as it is pretty old.
The problem we have is this. There was a small leak on the boiler a couple of months ago, when this was fixed the pressure raised to just below 3 bar, no matter how many times I bleed the radiators the pressure raises to just below 3 bar again. Recently the hot water, specifically to the bath, runs for about 30 secs - 1 minute hot then runs luke warm / cold. The water to the kitchen and bathroom sink are both running hot.
Is this just a case of replacing the boiler or is it something else which could be more easily rectified?
