how can i fix the pressure on my glo worm combi boiler?
my glo worm boiler is on approx 0.8 bar ? but i feel that the pressure in the shower is not powerful enough any suggestions ?one guy come out a while ago and said it was the thermistor then never come back? but this was when it wasnt working and for some reason it started working again but the shower has never been as powerful as it used to be also it is if the hot water runs out before the bath is full up?
0.8 bar refers to your heating pressure. if the valve which supplys the cold water to the boiler is fully open and the water flow to your taps are ok then you may have a problem with the shower. if the flow to the taps are poor then you may have a blockage or low pressure from th cold mains.
