Hello - I have a question about my Potterton Puma 110e. We have recently had the water mains sorted in our new house and the cold water pressure is now excellent. However, the hot water is not half a powerful which leads me to believe that it's to do with the boiler. It is registering at just over 1 bar but we want to install a shower and we need 2 bar pressure minimum. Should this make and model be able to reach 2 bar pressure or are we wasting our time. Very loathed to put in a new boiler as you would imagine.... Thanks in advance for your help.
